FAN BLADE SETTING DIMENSIONS
Shown in Figure 8 is the correct fan blade setting
dimension for proper air delivery across the outdoor coil.
Any service work requiring removal or adjustment in
the fan and/or motor area will require that the
dimensions below be checked and blade adjusted in or
out on the motor shaft accordingly.

Tables are based upon rated CFM (airflow) across the evaporator coil. If there is any doubt as to correct operating charge being
in the system, the charge should be removed, system evacuated and recharged to serial plate instruction

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.
