FAN BLADE SETTING DIMENSIONS
Any service work requiring removal or adjustment in
the fan and/or motor area will require that the
dimensions in Table 7 be checked and blade adjusted in
or out of the motor shaft accordingly.

Maximum ESP (inches WC) shown is with 1” thick disposable filter (reduced by .2 for 2” filter).
Rated CFM for ducted applications – required for maximum performance rating. To obtain full CFM on models QH362 and QH422
connect the pink jumper wire (provided) to terminal #5 and #6 on the low voltage terminal block located in the circuit breaker box.
Optional CFM – the unit is shipped from the factory set to operate at the optional CFM level shown. This provides lower operating
sound levels for non-ducted, free discharge applications. This reduces system capacity performance by approximately 2% at the same
energy efficiency.
Continuous fan CFM is the total air being circulated during continuous fan mode.
Indoor air flow during periods of high humidity when system is operating under control of optional humidistat for maximum humidity
reduction.
Models QH242 – when operating on 2nd stage heating the indoor air will increase to 1000 CFM.
REFRIGERANT CHARGE
The correct system R-22 charge is shown on the unit
rating plate. Optimum unit cooling performance will
occur with a refrigerant charge resulting in a Super Heat
as shown in Table 8. If correct charge is in doubt,
recover the refrigerant and recharge per the charge on
the unit rating plate.

NOTE: These units are equipped with a variable speed (ECM) indoor motor that automatically adjust itself to maintain
approximately the same rate of indoor air flow in both heating and cooling, dry and wet coil conditions and at
both 230/208 or 460 volts.
