Notes:
1 Nominal cooling capacities are based on the following conditions:
Return air temperature: 80°FDB(27°CDB), 67°FWB(19.4°CWB)
Outdoor temperature: 95°FDB (35°C)
Equivalent ref. piping: 25ft (7.5 m) (Horizontal)
2 Nominal heating capacities are based on the following conditions:
Return air temperature: 70°FDB (21°C)
Outdoor temperature: 47°FDB (8.3°CDB) , 43°FWB (6.1°CWB)
Equivalent ref. piping: 25ft (7.5 m) (Horizontal)
1 and 2 are the performance for vertical installation.
For horizontal installation, capacity could decrease by about 10%.
3 Capacities are net, including a deduction for cooling (an addition for heating) for indoor fan motor heat.
4 Air filter is not standard accessory, but please mount it in the duct system of the suction side.
5 A field-supplied secondary drain pan may be required.
