NOTES:

1.Performance based on nominal condenser airflow listed in physical data table on page 3.

2.SHC is based on 80 F db temperature of air entering the coil.

Below 80 F db, subtract (corr factor x cfm) from SHC.

Above 80 F db, add (corr factor x cfm) to SHC.

*Standard direct drive indoor (evaporator) fan motor (IFM). For optional belt drive IFM performance, see table on page 8.

NOTES:

1.Above fan performance is based on wet coil and deducted casing losses, and clean factory-installed permanent cleanable filter.

2.Evaporator fans are direct drive (except 048, 060 special order evaporator-fan motor option). Refer to Belt Drive Evaporator Fan Performance table on page 8.

3.Interpolation is permissible, do not extrapolate.

4.For units installed with accessory electric heaters, see Electric Heater Static Pressure Drop table for additional performance losses.
