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.
