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.
