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.

NOTE: These units are equipped with a variable speed (ECM) indoor motor that automatically adjusts itself to maintain
approximately the same rate of indoor airflow in both heating and cooling, dry and wet coil conditions and at both
230/208 or 460 volts.
 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 Q36H2, Q42H2,
Q48H2 and Q60H2, connect the pink jumper wire (provided) to terminal #G2 and #Y 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.
 Model Q24H2 – when operating on 2nd stage heating the indoor air will increase to 1000 CFM.

R-410A REFRIGERANT CHARGE
This unit was charged at the factory with the quantity
of refrigerant listed on the serial plate. AHRI capacity
and efficiency ratings were determined by testing with
this refrigerant charge quantity.
The following pressure tables show nominal
pressures for the units. Since many installation
specific situations can affect the pressure readings,
this information should only be used by certified
technicians as a guide for evaluating proper system
performance. They shall not be used to adjust charge.
If charge is in doubt, reclaim, evacuate and recharge
the unit to the serial plate charge.
