FAN BLADE SETTING DIMENSIONS

leaving face of the orifice plate. Check to make sure
the blades do not extend beyond the rear casing of the
unit. Spin the blade by hand to make sure it does not
hit the ring.
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 and temperatures 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.
