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.
