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.
