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.
Tables 8 and 9 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
.
