R-410A - Multi-Position - 50HZ (Export Only)Bulletin No. 490159

October 2013

7.0 to 17.6 kW (2 to 5 Tons)Optional Electric Heat

2.5 to 5 kWOptional Hot Water Heat

2.6 to 36.3 kW (9,000 to 124,000 Btuh)

CABINETEnhanced grommets - secure & tight.Multi-position available from factory and field convertible.Bottom return air on all models.All air handlers are basiloid packaged with bar coding and full description on label.Magnetic filter rack door makes for easy filter replacement and a tight seal for less air leakage.Fiberglass air filter furnished with every air handler and filter racks accepts readily available size filters.Taupe painted cabinets constructed of heavy gauge steel to prevent corrosion and are lined with high quality 9.5 mm (5/8 in.) foil faced insulation to prevent sweating.

EVAPORATOR COILPatented lanced fin design and internally enhanced copper tubing.Suitable for use with R-410A.Dual 19 mm (3/4 in.) FPT left and right condensate drain connections.Drain pans are molded of corrosion proof high temperature engineering polymer.Coils are air pressure tested at 72 kPa (500 PSI), pressure tested with Helium, sealed and then charged with dry air.All models have a factory-installed, internal check/expansion valve.

HOT WATER HEATSuitable for potable water systems.Hot Water Heat Coil available factory installed.Easy to remove hot water coil for servicing. Remove one screw and slide out.Purge valve on hot water coil allows for manual release of any air trapped in coil during installation or servicing.Water connections 7/8 in. ODF (for 3/4 in. water pipe) on 24 size models and 1-1/8 in. ODF (for 1 in. water pipe) on 37 and 60 size models.

Control board comes standard factory installed on all Air Handlers and includes the following features:

Features are compatible for field installed circulating pumps.1. Pump timer activates pump for 1 minute every 6

hours eliminating stagnant water in hot water coil.2. 24 VAC isolation valve control-allows for zoning

control.3. Auxiliary contacts for water heater or boiler

activation.4. Freeze protection- standard factory installed,

activates at 4°C (40°F) and deactivates at 21°C (70°F).

5. Thermostat connections.6. Time delay for blower activation:

• 60 seconds (tap in OFF position)• 54°C (130°F) aquastat (tap in ON position)

HYDRONIC SYSTEM DESIGN

Hydronic System DesignIncludes: Heating coil selection, line sizing and selected pump supplied by other

Sample Application

10.5 kW Cooling Load82o C Water Temp40% Glycol Mixture17.6 kW Heat Required

(1) From the 10.5 kW heating capacity tables select a hot water coil that supplies at least 17.6 kW at 565 L/s, 82°C water temperatureThe 3 row coil supplies 20.2 kW @ 14.8 LPM, 0.5 kPa pressure drop 20.2Correct capacity for 40% glycol (correction factors found below capacity chart) X 0.88Corrected coil heating capacity (kW) = 17.7

(2) Determine total equivalent line lengthNote: Use the following line sizes as a guide for initial selection1 - 11.1 LPM, 19 mm 4 - 18.5 LPM, 25 mm 6 - 29.6 LPM, 32 mm

Line size 25 mm Equiv. length of Total number of fittings Quantity pipe (Table 3)

90o SR elbows 20 X 0.79 m =90o LR elbows 0 X 0 = 0 + 045o elbows 0 X 0 = 0 + 0gate valves 2 X 533 mm = 1.2 m + 1.1 m

Total supply and return line length + 56.7 mTotal equivalent line length = 74.3 m

(3) Determine total pump head required Press. Drop/Pa(Table 1)

Total equivalent line length 74.3 m X 3.7 = 2.75 1.1 mTotal pressure drop through coil (found on capacity chart) + 0.67 mLine length correction factor for 40% glycol @ 82°C (Table 2) X 1.12Total pump head required 2.0 m

(4) Now select a pump that supplies 14.8 LPM with at least 2.0 m head capability.Note: If desired, recalculation can be done with another line size to vary pump requirement.
