FAN BLADE SETTING DIMENSIONS

The position of the fan blade should be flush with the
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.
