  • IMPORTANT INFORMATION

    WARNINGWARNINGSYSTEM CONTAMINANTS, IMPROPER SERVICE PROCEDURE AND/OR PHYSICAL ABUSE AFFECTINGHERMETIC COMPRESSOR ELECTRICAL TERMINALS MAY CAUSE DANGEROUS SYSTEM VENTING.

    System contaminants, improper Service Procedure and/or physical abuse affecting hermetic compressor electricalterminals may cause dangerous system venting.

    The successful development of hermetically sealed refrigeration compressors has completely sealed the compressor'smoving parts and electric motor inside a common housing, minimizing refrigerant leaks and the hazards sometimesassociated with moving belts, pulleys, or couplings.

    Fundamental to the design of hermetic compressors is a method whereby electrical current is transmitted to thecompressor motor through terminal conductors which pass through the compressor housing wall. These terminals aresealed in a dielectric material which insulates them from the housing and maintains the pressure tight integrity of thehermetic compressor. The terminals and their dielectric embedment are strongly constructed, but are vulnerable tocareless compressor installation or maintenance procedures and equally vulnerable to internal electrical short circuitscaused by excessive system contaminants.

    In either of these instances, an electrical short between the terminal and the compressor housing may result in the lossof integrity between the terminal and its dielectric embedment. This loss may cause the terminals to be expelled, therebyventing the vaporous and liquid contents of the compressor housing and system.

    A venting compressor terminal normally presents no danger to anyone providing the terminal protective cover is properlyin place.

    If, however, the terminal protective cover is not properly in place, a venting terminal may discharge a combination of

    (a) hot lubricating oil and refrigerant

    (b) flammable mixture (if system is contaminated with air)

    in a stream of spray which may be dangerous to anyone in the vicinity. Death or serious bodily injury could occur.

    Under no circumstances is a hermetic compressor to be electrically energized and/or operated without having the terminalprotective cover properly in place.

    See Service Section S-17 for proper servicing.

    CONDENSING UNITThe RHA, RHD and RHE Remote Heat Pumps are made in1.5 through 5 ton sizes. They are designed for dual voltagesingle phase applications. The RHA 3, 4, and 5 ton modelsare also available for 230V and 460V 3 phase applications.The condenser air is pulled through the condenser coil by adirect drive propeller fan. This condenser air is then dis-charged out of the top of the cabinet.These units are designed for free air discharge, so no addi-tional resistance (like duct work) shall be attached.The suction and liquid line connections are of the sweat typefor field piping with refrigerant type copper. Non-back seat-ing valves are factory installed to accept the field run cop-per. The total refrigerant charge for a normal installation isfactory installed in the condensing unit. This charge is forthe matching evaporator coil and a 25 foot refrigerant lineset.Refrigerant line sizes listed in the Specification section arefor 50 feet or less. The maximum length of refrigerant linesis 50 feet with no more than a 20 foot vertical rise. In thiscase additional refrigerant must be added for the extra 20foot of lines.Systems should be properly sized by heat gain and losscalculations made according to methods of the Air Condi-tioning Contractors Association (ACCA) or equivalent. It isthe contractors responsibility to ensure the system has ad-equate capacity to heat or cool the conditioned space.RHD & RHE models use the Compliant Scroll compressor.There are a number of design characteristics which are dif-ferent from the traditional reciprocating compressor.- Phase 1 Scroll compressors include a discharge thermo-stat located beneath the compressor top cap.- Phase 2 Scroll compressors will not have a discharge ther-mostat.- Due to their design Scroll compressors are inherently moretolerant of liquid refrigerant.NOTE: Even though the compressor section of a Scroll com-pressor is more tolerant of liquid refrigerant, continued flood-back or flooded start conditions may wash oil from the bear-ing surfaces causing premature bearing failure.- These Scroll compressors use white oil which is compat-ible with 3GS. 3GS oil may be used if additional oil is re-quired.- The compressor may run backwards (noisy operation) for1 or 2 seconds at shutdown. This is normal and does notharm the compressor.- Operating pressures and amp draws may differ from stan-dard reciprocating compressors. This information may befound in the "Expanded Performance Data" section.

    - The 3 phase Scroll Compressors are direction of rotationsensitive. They will rotate in either direction depending onthe phasing of the power. Verification of proper rotation ismade as follows.1. Install gauges and verify that the suction pressure drops

    while the discharge pressure increases.2. Listen for normal compressor sound levels. Reverse ro-

    tation results in elevated or unusual sound levels.3. Reverse rotation will result in substantially reduced amp

    draw from tabulated values.To correct improper rotation, switch any two power supplyleads at the outdoor unit contactor.There is no negative impact on durability caused by operat-ing 3 phase compressors in reversed rotation. The com-pressors internal protector will trip, de-energizing the com-pressor.The scroll is a simple compression concept first patented in1905. A scroll is an involute spiral which, when matchedwith a mating scroll form, generates a series of crescentshaped gas pockets between the two members. See thefollowing illustration.During compression, one scroll remains stationary (fixedscroll) while the other form (orbiting scroll) is allowed to orbit(but not rotate) around the first form.As this motion occurs, the pockets between the two formsare slowly pushed to the center of the two scrolls while si-multaneously being reduced in volume. When the pocketreaches the center of the scroll form, the gas, which is nowat a high pressure, is discharged out of a port located at thecenter.During compression, several pockets are being compressedsimultaneously, resulting in a very smooth process. Boththe suction process (outer portion of the scroll members)and the discharge process (inner portion) are continuous.

    BLOWER COILSThese blower coils are designed with matching evaporatorcoils to provide an air handler for heat pump operation. Elec-tric heater kits (EHK-A) are available as sales accessoriesfor supplement electric heat.The BHA-T models are equipped with a thermostatic ex-pansion and check valve assembly for refrigerant metering.The BHA-F models are equipped with a restrictor orifice.The units are designed for upflow, counterflow, or horizon-tal application, using two speed direct drive motors on theBHA-FA & TA models, and BPM (Brushless PermanentMagnet) or ECM motor on the BHA-TB models.

    COILS AND BLOWERSAmana CCA & CHA model "A" coils are designed for upflowand counterflow operation. The CCH & CHH model slabcoils, and the CCF & CHF model cased "A" coils are de-signed for horizontal applications.These coils are designed to be installed with a furnace or airhandler and matched with Amana's heat pumps to providehigh efficiency cooling and heating. Thermal expansionvalves on the CCA_T, CHA_T, CHH and CHF coils and re-strictor orifices on the CCA_F, CCH and CCF coils provideaccurate refrigerant control and provide reliable operationover a wide range of conditions.Models CCA30FUA and CCA60FUA have restrictors fac-tory installed for 2 1/2 ton and 5 ton applications. Applica-tions with the 2 ton and 4 ton require a change in the restric-tor.All expansion valves used on indoor coils and blowers areof the non-bleed type.To avoid poor operation and/or equipment damage, anysingle-phase reciprocating compressor used with a ex-pansion valve coil must include hard start components.BBA and BBC model blower cabinets are designed as a twopiece blower coil. The BBA/BBC is the blower section whichattaches to a cased evaporator coil. This two piece arrange-ment allows for a variety of mix-matching possibilities pro-viding greater flexibility.BBC models use a variable speed motor that maintains arelatively constant airflow regardless of duct static. BBCmodels are approved for applications with cooling coils ofup to 0.8 inches w.c. external static pressure. The BBC'sinclude a feature that allows airflow to be changed by 15percent. If lower airflow is desired, place the "ADJUST" pinon the "-" setting. If higher airflow is desired, place the "AD-JUST" pin on the "+" setting.As a modular blower coil, the intended use is for applica-tions with a cased evaporator coil and a condensing unit orheat pump. The blower section may also be used as anelectric furnace. In either case, electric heating elementsare field installed. Electric heater kits (EHK-B & ECB-B) areavailable as sales accessories for supplement electric heat.

    The unit may be positioned for upflow, counterflow, horizon-tal right or horizontal left operation. All units are constructedwith R-4.2 insulation. In areas of extreme humidity (greaterthan 80% consistently), the installer should insulate the ex-terior of the blower with insulation having a vapor barrierequivalent to insulation used on ductwork, if local codespermit.

    NOTE: Restrictor orifice size should always be matched tothe OD unit being used.Suction line accumulators are used on outdoor units withreciprocating compressors for additional protection for thecompressor. The object of the accumulator is to:1. Provide a liquid refrigerant storage vessel during pro-

    longed system off cycles.2. Store excess liquid refrigerant not needed by the sys-

    tem while running.3. Return oil and saturated vapor to the compressor at a

    controlled rate.4. Retain stored excess refrigerant during a sudden sys-

    tem pressure fluctuation such as seen in defrost cycles.

    COOLINGThe refrigerant used in the system is R-22. It is a clear, col-orless, non-toxic, non-irritating, and non-explosive liquid. Thechemical formula is CHCLF2. The boiling point, at atmo-spheric pressure is -41.4F.A few of the important principles that make the refrigerationcycle possible are: heat always flows from a warmer to acooler body, under lower pressure a refrigerant will absorbheat and vaporize at a low temperature, the vapors may bedrawn off and condensed at a higher pressure and tem-perature to be used again.The indoor evaporator coil functions to cool and dehumidifythe air conditioned spaces through the evaporative processtaking place within the coil tubes.NOTE: The pressures and temperatures shown in the re-frigerant cycle illustrations on the following pages are fordemonstration purposes only. Actual temperatures and pres-sures are to be obtained from the "Expanded PerformanceChart."Liquid refrigerant at condensing pressure and temperatures,(270 psig and 122F), leaves the outdoor condensing coilthrough the drier and is metered into the indoor coil throughthe metering device. As the cool, low pressure, saturatedrefrigerant enters the tubes of the indoor coil, a portion ofthe liquid immediately vaporizes. It continues to soak up heatand vaporizes as it proceeds through the coil, cooling theindoor coil down to about 48F.Heat is continually being transferred to the cool fins and tubesof the indoor evaporator coil by the warm system air. Thiswarming process causes the refrigerant to boil. The heatremoved from the air is carried off by the vapor.As the vapor passes through the last tubes of the coil, itbecomes superheated, that is, it absorbs more heat than isnecessary to vaporize it. This is assurance that only dry gaswill reach the compressor. Liquid reaching the compressorcan weaken or break compressor valves.The compressor increases the pressure of the gas, thusadding more heat, and discharges hot, high pressure su-perheated gas into the outdoor condenser coil.In the condenser coil, the hot refrigerant gas, being warmerthan the outdoor air, first loses its superheat by heat trans-ferred from the gas through the tubes and fins of the coil.The refrigerant now becomes saturated, part liquid, partvapor and then continues to give up heat until it condensesto a liquid alone. Once the vapor is fully liquefied, it contin-ues to give up heat which subcools the liquid, and it is readyto repeat the cycle.

    HEATINGThe heating portion of the refrigeration cycle is similar to thecooling cycle. By energizing the reversing valve solenoid coil,the flow of the refrigerant is reversed. The indoor coil nowbecomes the condenser coil, and the outdoor coil becomesthe evaporator coil.The check valve at the indoor coil will open by the flow ofrefrigerant letting the now condensed liquid refrigerant by-pass the indoor expansion device. The check valve at theoutdoor coil will be forced closed by the refrigerant flow,thereby utilizing the outdoor expansion device.The restrictor orifice used with the CCA-F, CCH-F and BHA-F coils will be forced onto a seat when running in the cool-ing cycle, only allowing liquid refrigerant to pass through theorifice opening. In the heating cycle it will be forced off theseat allowing liquid to flow around the restrictor. A checkvalve is not required in this circuit.

    COOLING CYCLEWhen the contacts of the room thermostat close makingterminals R to Y to G, the low voltage circuit of the trans-former is completed. Current now flows through the mag-netic holding coils of the compressor contactor (CC) andfan relay (RFC).This draws in the normally open contact CC1, starting thecompressor and condenser fan motors. At the same timecontacts RFC close starting the indoor fan motor.When the thermostat is satisfied, it opens its contacts, break-ing the low voltage circuit, causing the compressor contac-tor and indoor fan relay to open, shutting down the system.If the room thermostat fan selector switch should be set onthe "on" position, then the indoor blower would run continu-ous rather than cycling with the compressor.RHA, RHD & RHE models energize the reversing valve thor-ough the "O" circuit in the room thermostat. Therefore thereversing valve remains energized as long as the thermo-stat subbase is in the cooling position. The only exception tothis is during defrost.

    HEATING CYCLEThe RHA & RHD model heat pumps use a different controlcircuit than preceding heat pump models. These models donot use a reversing relay to energize the reversing valve.Also many previous models energized the reversing valveoff the "B" terminal on the thermostat, and all previous mod-els energized the reversing valve in the heating cycle.

    The reversing valve on the RHA, RHD & RHE models isenergized in the cooling cycle thorough the "O" terminal onthe room thermostat.These models have a 24 volt reversing valve coil. When thethermostat selector switch is set in the cooling position, the"O" terminal on the thermostat is energized all the time.Care must be taken when selecting a room thermostat. Re-fer to the installation instructions shipped with the productfor approved thermostats.If electric heaters are utilized, a two stage heating and singlestage cooling thermostat should be used.Should the second stage heating contacts in the room ther-mostat close, the first stage of electric heat would becomeenergized. If additional electric heaters are used, they wouldbe controlled by the sequencer on the proceeding heater. Ifinstalled, the electric heaters may be controlled by outdoorthermostats.

    DEFROST CYCLEThe defrosting of the outdoor coil is jointly controlled by thedefrost timer board, defrost (30/60) control, and compres-sor run time.Solid State Timer RHA-A2A ModelsThe defrost timer board can be connected for one of three(3) time intervals. Post T1 = 30 minutes, Post T2 = 60 min-utes, and Post T3 = 90 minutes (Factory connected).The timing interval can not commence until the outdoor coiltemperature reaches approximately 30F. (initiation tempera-ture) at the defrost terminator (30/60) control point of con-tact. As long as this point of contact does not reach 60F.(termination temperature), the defrost timer board will countthe number of minutes that the compressor runs.At the end of this (one of three) time interval, the defrosttimer board will call for defrost and energize the defrost (DFR)relay. This relay has four sets of contacts of which one is inthe line voltage circuit (normally closed) in series with theoutdoor fan motor. When this contact opens, the outdoorfan motor stops. The other three sets of contacts (normallyopen) are in the low voltage circuit. One set of contacts con-trol the reversing valve. When closed, the reversing valveenergizes, switching over to the cooling position sendinghot refrigerant gas to the outdoor coil, which will start to meltany frost accumulation. Another set of contacts close, lock-ing in the compressor until defrost is completed. The thirdset will energize the electric heat if available.The defrost timer board will keep the defrost (DFR) relayenergized until the outdoor coil temperature reaches approxi-mately 60F at the 30/60 control, or a maximum of 10 min-utes compressor run time.If the defrost cycle is terminated by temperature, then a newtime interval count cannot begin until the defrost (30/60) con-trol again reaches approximately 30F. If the defrost cyclewas terminated by time, then a new time interval would be-gin immediately.Integrated Defrost Control RHA-A2B ModelsThe operation of the integrated defrost control used on theRHA-A2B models is very similar to that of the solid statecontrol described above. The time interval is determined bythe position of the time select jumper which is factory set tothe specific unit design. The control will default to 90 min-utes if the jumper is missing or if the jumper is left in the testposition for more than 5 minutes.The board counts the compressor run time in the heatingmode after the 30/60 control closes. If the 30/60 controlopens, the timer will reset. The board will terminate defrostwhen the 30/60 control opens or after 14 minutes compres-sor run time which ever occurs first. If the thermostat is sat-isfied during the defrost cycle, timing is suspended, the boarddoes not reset.NOTE: RHA30 & 36 A2B units are factory set to 30 minutes.

    It is not recommended to change the defrost times on theseunits. All other models are factory set for 90 minutes andcan be adjusted to accommodate local conditions.Some additional features that are built into this controlare;Short cycle protection - The 11164401 integrated defrostcontrol includes short cycle protection. A five minute lock-out will occur when the 24 VAC power to the contactor isremoved by the thermostat demand cycling off or by theopening of a pressure switch.Pressure switch protection - When a pressure switchopens, the contactor is locked out for five minutes. After 5minutes, if the pressure switch is closed, normal operationwill resume. Note: The RHA__A2B units have a second 30/60 control which bypasses the low pressure control at thestart of the defrost mode to avoid nuisance tripping of thelow pressure switches in this phase of the defrost function.Three time Lockout Feature - After 3 pressure switch open-ings within a single heating or cooling cycle, all functions willbe locked out. Lockout is reset by cycling off the thermostator by removing 24 VAC power to the board. Note: TheRanco board requires interrupt of 24 VAC to the board toreset.Adaptive Defrost System RHD/RHE ModelsThe adaptive defrost board works in much the same way asthe standard solid state timer except that it is not set to afixed time between defrosts. Defrosts may be a minimum of30 minutes apart, to a maximum of 180 or 360 minutes (de-pendant on control model) apart depending on conditions.The optimum defrost time is programmed into the defrostcontrol (5.5 or 7 minutes). If the defrost takes less than theoptimum defrost time, the defrost board will increase thetime before the next defrost. If the next defrost also is lessthan the optimum defrost time, the board will again increasethe time before the next defrost.As conditions change increasing the frost build up on thecoil, the length of defrost will also increase above the opti-mum defrost time, causing the defrost cycles to come morefrequently.See section S-23 in the servicing portion of this manual foradditional information and servicing of the defrost control.

    BBA Standard Efficiency Blower SectionSequence of OperationBBA Cooling-Only OperationsThe cooling operation is fairly straight forward. With the ther-mostat in the FANAUTO position and a Y or G call,the blower starts within three seconds. When the Y call issatisfied, the blower will stay on until the supply tempera-ture is greater than 65F or up to a maximum of forty-fiveseconds, whichever occurs first.BBA Electric Heat-Only OperationsAs in the cooling-only operations, with the thermostat in theFANAUTO position and a W2 or E call, the blowerstarts within three seconds. The board then starts turning-on banks of electric heat, one every ten seconds, until thesupply temperature reaches 90F. If the W2 or E call hasnot been satisfied within the next five minutes, the boardturns-on additional banks of heaters and increases the mini-mum supply temperature from 90F to 105F. If an addi-tional five minutes passes and the W2 or E call has notbeen satisfied, the board will raise the minimum supply tem-perature to 120F and once again turns-on additional banksof electric heaters.Should the temperature at the thermistor go above 140F,the control logic will start turning off one bank of heatersevery ten seconds until the temperature falls below 140F.If the temperature climbs above 150F, the control logic turnsoff all electric heat. If the temperature goes above 170F,probably due to a component failure, the control logic turnsoff all power to the heaters and keeps the blower on until thetemperature falls below 90F.BBA Heat Pump Only OperationsThe control process for heat pump operations is very simi-lar to the electric heat only operations, with the thermostatin the FANAUTO position and a Y call, the blower startswithin three seconds. When the Y call is satisfied, the blowerwill stay on until the supply temperature is less than 90F orup to a maximum of forty-five seconds, whichever occursfirst.BBA Heat Pump Operations with Back-up Electric HeatThe major difference when electric heat is added is that theboard can be preset for electric heat lockout and minimumsupply air temperatures of 85F, 90F, 95F, or 100F. Thisdischarge air temperature setting will be used to lock-outthe electric heaters as long as the heat pump cycle satisfiesthe minimum supply air temperature.

  • SYSTEM OPERATION

    30 Rev. 1

    Two conditions must exist for the electric heat to be acti-vated:

    1. The thermistor is sensing temperatures below the setpoint with the heat pump heating operation, and

    2. There is a W2 call.So, if the heat pump cycle fails to satisfy the W2 call, theboard shifts to integrated heating operation which is just likethe electric heater only operation except that the initial mini-mum supply air for the heat pump cycle plus the electricheaters will be 105F instead of 90F.BBA Fan Idle OptionThe control board has a special option for the BBA models.The blower motor is wired for only one speed for heatingand cooling operations. Another tap for the motor can beuse to connect the lower or idle speed. With the thermo-stat in the FANAUTO position, the board allows the motorto operate at the lower speed during system off cycles forminimum circulation air. When the thermostat is switchedto the FANON position, the blower motor will operate atthe higher cooling speed.

    BBC High Efficiency Blower SectionSequence of OperationIt is important to note that the operational logic for thecontrol board for the BBCs is different from the BBAboard, hence, they are not interchangeable.The BBCs, like the BHA**TBs with the ECM variable speedmotor, use the variable speed to maintain constant CFM.However, there is a new twist to the BBCs with the controlboard logic that changes the CFM in response to over-tem-perature and under-temperature conditions with help fromthe discharge air temperature readings from the new dis-charge air thermistor.BBC Cooling-Only OperationsWith the thermostat in the FANAUTO position and a Yor G call, the blower ramps up to speed over a 30 secondperiod. The acceptable cooling operation temperature rangeis 45 to 65F. If the supply air temperature is above the ac-ceptable range, 65F, the control logic decreases the CFM,until the Y or G call is satisfied. Then, on the next Y orG call the CFM will return to the preset level. If the supplyair temperature is below the acceptable range, 45F, thecontrol logic increases the CFM until the Y call is satisfied.Then, on the next Y or G call the CFM will return to thepreset level. In both cases, the blower will stay on at nomi-nal CFM until the supply temperature is greater than 65For up to a maximum of forty-five seconds, whichever occursfirst. At that time the motor will ramp the CFM down over thenext 30 seconds.

    BBC Electric Heat-Only OperationsAs in the cooling-only operations, with the thermostat in theFANAUTO position and a W2 or E call, the first bankof electric heat is energized as the blower ramps up to speedover a 30 second period. The control logic continues turn-ing-on banks of electric heat, one every ten seconds, untilthe supply temperature reaches 90F. The board will thenkeep all existing banks of electric heaters on until the W2or E call has been satisfied.If the supply air temperature is above the upper limit of theacceptable range, 140F, the control turns off one bank ofheaters every 10 seconds until the temperature falls below140F. Should the temperature exceed 150F, the controllogic will shut-off all electric heat and runs the fan continu-ously until the temperature is back below 90F.BBC Heat Pump Only OperationsThe control process for heat pump operations is very simi-lar to the cooling only operations, with the thermostat in theFANAUTO position and a Y call, the blower ramps up tospeed over 30 second period. The acceptable heating op-eration temperature range is 90 to 105F. If the supply airtemperature is above the acceptable range (105F) the con-trol logic increases the CFM until the Y call is satisfied. Ifthe supply air temperature is below the acceptable range(90F) the control decreases the CFM. In either case theairflow returns to the preset level on the next call for heat-ing.BBC Heat Pump Operations with Back-up Electric HeatThe major difference when electric heat is added is that theboard can be preset for minimum supply air temperaturesof 85F, 90F, 95F, or 100F. This discharge air tempera-ture setting will be used to lock-out the electric heaters aslong as the heat pump cycle satisfies the minimum supplyair temperature. If the heat pump cycle fails to satisfy theW2 call, the control will first decrease the airflow to try toobtain the minimum supply temperature. If a lower airflow isunsuccessful, the control board then returns to the presetairflow level and shifts to integrated heating operation whichis just like the electric heater only operation except that theinitial minimum supply air for the heat pump cycle plus theelectric heaters will be 105F instead of 90F. The controllogic will then operate as for the electric heat only operation.BBC Manual Fan OperationThe control board has a special option for the BBC models.When the thermostat is switched to the FANON position,the blower motor will operate at either 50% or 100% of thecooling speed. This is accomplished with the use of the "LowSpeed Manual Fan" jumper located just below the indicatorlight on the control board. With the jumper in place (asshipped) the blower will operate at 50% of the nominal cool-ing speed selected. With the jumper removed the blowerwill operate at 100% of the nominal blower speed selected.

    ELECTRIC HEATERS

    Optional electric heaters may be added, in the quantitiesshown in the specifications section to provide electric resis-tance heating. Under no condition shall more heaters thanthe quantity shown be installed.The low voltage circuit in the air handler is factory wired andterminates at the location provided for the electric heater(s).A minimum of field wiring is required to complete the instal-lation.Other components such as a Heating/Cooling Thermostatand Outdoor Thermostats are available to complete the in-stallation.The system CFM can be determined by measuring the staticpressure external to the unit. The installation manual sup-plied with the blower coil, or the blower performance table inthe service manual shows the CFM for the static measured.Alternately, the system CFM can be determined by operat-ing the electric heaters and indoor blower WITHOUT hav-ing the compressor in operation. Measure the temperaturerise as close to the blower inlet and outlet as possible.If other than a 240V power supply is used, refer to the BTUHCAPACITY CORRECTION FACTOR chart below.EXAMPLE: Five (5) heaters provide 24.0 KW at the rated240V. Our actual measured voltage is 220V, and our mea-sured temperature rise is 42F. Find the actual CFM:Answer: 24.0KW, 42F Rise, 240 V = 1800 CFM from theTEMPERATURE RISE chart on the right.Heating output at 220 V = 24.0KW x 3.413 x .84 = 68.8MBh.Actual CFM = 1800 x .84 Corr. Factor = 1400 CFM.NOTE: The temperature rise table is for sea level installa-tions. The temperature rise at a particular KW and CFM willbe greater at high altitudes, while the external static pres-sure at a particular CFM will be less.

    FORMULAS:

    Heating Output = KW x 3413 x Corr. Factor

    Actual CFM = CFM (from table) x Corr. Factor

    BTUH = KW x 3413

    BTUH = CFM x 1.08 x Temperature Rise (T)

    CFM = KW x 34131.08 x T

    T = BTUH CFM x 1.08
