UNIT FEATURES & OPTIONSA. GENERALThe Zamil Condensing units are environment friendly units that use refrigerant R-134a and incorporate the latest innovativetechnology to provide quiet, reliable performance. The wrap-around coil not only adds to the aesthetical appeal, it also givesoptimum heat transfer efficiency. The access panels provide access to the compressor, fan motor and to the electricalcontrol box.

These condensing units can be combined with a wide variety of evaporator coils and blower packages to provide quietand dependable comfort. These units can be installed on a roof or at ground level.

B. UNIT ENCLOSUREAll panels are of heavy gauge (G-90) galvanized steel sheet and completely weatherized for outdoor installation. Steelsheet panels are zinc coated and galvanized by the hot dip process of lock-forming quality conforming to ASTM A 653commercial weight G-90, followed by baked on electrostatic polyester dry powder coat.

C. COMPRESSORHermetic scroll compressors are used as standard as shown in the physical data. They are provided with all the standardcontrols necessary for proper and safe operation. These compressors have a self-regulating crankcase heater, improvedinternal pressure relief valve which provides high pressure protection to the refrigerant system and vibration isolators forquiet and efficient operation.

D. AIR COOLED CONDENSER1. The large wrap-around condenser coil is of corrugated fin & tube type, constructed of enhanced copper tubes and

mechanically bonded to aluminum fins. As an option to aluminum fins, coated aluminum fins or corrugated copper finsmay be provided. Tube support sheets are of galvanized steel, formed to provide structural strength. Tubes are cir-cuited to ensure minimum pressure drop and maximum heat transfer. Each coil is completely dehydrated, charged andsealed at the factory upon completion of pressure tests.

INSTALLATION & START-UP INSTRUCTIONSSAFETY CONSIDERATIONSImproper installation, service, maintenance or use can cause explosion, fire, electrical shock or other conditions whichmay cause personal injury or property damage. Check with your nearest Zamil dealer/sales office for information orassistance.

WarningBefore installation or servicing the system, always turn off main power supply. Electrical shock can cause personal injuryor death.

INSTALLATIONSTEP-1:Check equipment and job siteUnpack unit and move to final location taking care not to damage the unit. Remove screws holding the unit to woodenpallet and after removing wooden pallet, refix the screws.

STEP- 2:Installation on a solid, level mounting padFor proper drainage, the condensing unit must be raised off the mounting pad. If conditions require the unit be attached tothe pad, tie down bolts should be used.

When installing, allow sufficient space for airflow clearance, wiring, refrigerant piping and service. Double the serviceaccess when multiple units are installed at one location.

On rooftop applications, locate unit at least 6" (152 mm) above roof surface. Place unit above a load-bearing wall, isolateunit and piping set from structure.Arrange supporting members to adequately support unit and minimize transmission of vibration to building.

STEP-3:Piping connectionsOutdoor units should be connected to indoor units using field-supplied piping of refrigerant grade and correct size. Theliquid and suction line diameters can be determined from the physical data table. For piping requirements beyond 25 ft(7.62m), obtain information from your nearest Zamil dealer/sales office.If either refrigerant piping or indoor coil is exposed to atmospheric conditions, it must be dehydrated to 500 microns toeliminate moisture contamination in the system.It is advisable to size piping according to recommended ASHRAE methods. Install piping according to refrigerationstandard practice. Run refrigerant pipes as directly as possible, avoiding unnecessary turns and bends. Install refrigerantpipes carefully to prevent damaging the suction pipe insulation and vibration transmission to the structure.

Outdoor unit connected to factory matched indoor unitOutdoor unit contains correct system refrigerant charge for operation with matched indoor unit as given on cooling capac-ity table and when connected with up to 25 ft (7.62 m) of field-supplied piping. Check refrigerant charge for maximumefficiency.

Sweat connectionUse refrigerant grade piping. Service valves are closed from factory when shipped and ready for brazing. After wrappingthe service valve with a wet cloth, the piping set can be brazed to service valve using either silver rod or silfos rod brazingmaterial. When brazing completed, refrigerant piping and indoor coil are now ready for leak testing. This check shouldalso include all field and factory brazed joints.

ELECTRICALSTEP 1: INSTALLATIONA) Please ensure power supply to the unit is as per unit nameplate (Volts/Ph/Hz) requirements.

Caution: Operation of the unit on improper power supply will result in damage to the unit.Note: Use copper wires of proper rating for all field wiring.

Warning: Before servicing or installation of the unit, always TURN OFF all power to the unit. There may be more than onedisconnect switch. Ensure all of them are turned off. Electrical shock can cause personal injury or death.

B) Ground & power wiresConnect power wires to terminal block per wiring diagram.Connect ground wire to the ground lug inside the control box.

C) Control wiring between outdoor & indoor unitUse 16 gauge color-coded wire between the indoor and outdoor units (control wiring).

STEP 2: START-UP1) Energize crankcase heater for a minimum of 12 hours prior to the system start-up. To energize crankcase heater only,

set thermostat to "off" position and close electrical disconnect switch to the outdoor unit.2) Fully open liquid/suction service valves.3) Close electrical disconnect switch to energize the system.4) Set room thermostat to desired temperature.

SYSTEM DESIGNTHE ZAMIL CONDENSING UNIT SYSTEM HAS BEEN DESIGNED BASED ON THE FOLLOWING:

• Intended for outdoor installation with free air intake and discharge.

• Minimum outdoor operating air temperature during cooling without low ambient operation option is 550F.

• Maximum outdoor operating air temperature during cooling is 1300F.

• For reliable operation, unit should be level on horizontal plane.

• Maximum elevation of indoor unit above or below the outdoor unit is: indoor unit above = 50 feet, indoor unit below =150 feet.

• For interconnecting refrigerant pipe lengths greater than 25 feet, check with your local Zamil sales office.

• Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type ofconnector provided.
