•Heating airflows with dry coil; cooling airflows with wet coil
NOTES:
1 Air delivery values are based on 230-v unit operating voltage without air
filter or optional electric heaters. Deduct field-supplied air filter and elec­
tric heater pressure drop to obtain external static pressure available for
ducting
2. Dashes indicate portions of table that are beyond indoor-fan motor
capability
NOTES:
1. Shading indicates integrated ratings
2. Integrated capacity is maximum (instantaneous) capacity less the effect
of frost on the outdoor coil and the heat required to defrost it.
3. Do not operate unit at a cooling airflow less than 350 cfm for each 12,000
Btuh of rated cooling capacity. Operation at airflow below this point may
result in frost on indoor coil
4 See Minimum Airflow (Cfm) for Safe Electric Heater Operation table on
page 13 for minimum airflow required for field-installed electric heaters.
