R-410A 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 pressure table on the following page shows
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.
