REFRIGERANT CHARGE
The correct system R-410A charge is shown on the unit
rating plate. Optimum unit performance will occur with
a refrigerant charge resulting in a suction line
temperature (6" from compressor) as shown in Table
2A. If charge quantity is in doubt, reclaim unit and
recharge to factory nameplate quantity.

The correct system R-410A charge is shown on the unit
nameplate. Optimum unit performance will occur with
a refrigerant charge resulting in a liquid subcooling as
shown in Table 2B. If charge is in doubt, reclaim and
