REFRIGERANT CHARGE

This unit was charged at the factory with the quantity of

refrigerant listed on the serial plate. AHRI capacity and

efciency ratings were determined by testing with this

refrigerant charge quantity.

The following pressure tables show nominal pressures

for the units. Since many installation specic situations

can affect the pressure readings, this information should

only be used by certied 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.
