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 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.
