SYSTEM CHARGE

The factory charge in the outdoor unit includes enough charge for the unit and a most sold matched evaporator. Some indoor coil matches may require some additional charge. See Tabular Data sheet provided in unit literature packet.

Sweat connect units also include sufficient charge for 15 feet of lines. Pre-charged line lengths are factory charged with the correct amount of refrigerant required. Table 2 lists the refrig- erant line charges.

The “TOTAL SYSTEM CHARGE” must be permanently stamped on the unit data plate.

Total system charge is determined as follows:

1.Determine outdoor unit charge from tabular data sheet.

2.Determine indoor coil adjustment from tabular data sheet.

3.Calculate the line charge using Table 2 factors. Calculate over 15 feet of sweat lines for sweat connect units.

NOTE: For sweat connect lines, the line charge over 15 feet should be included on the data plate and must be added to the system.

4.Total system charge = item 1 + item 2 + item 3.

5.Permanently stamp the unit data plate with the total amount of refrigerant in the system.

Use one of the following charging methods whenever addi- tional refrigerant is required for the system charge.

Refrigerant charging should only be carried out by a qualified air conditioning contractor.

MEASUREMENT METHOD

If a calibrated charging cylinder or accurate weighing device is available, add refrigerant accordingly.

Compressor damage will occur if system is improperly charged. On new system installations charge system per R-22 charge information label and follow guidelines in this instruction.

Check flare caps on service ports to be sure they are leak tight. DO NOT OVER TIGHTEN (between 40 and 60 inch - lbs. maximum).

SUPERHEAT CHARGING METHOD

NOTE: Use this method only during system maintenace and repair.

1.Operate system until temperatures and pressures stabi- lize (minimum of 10 minutes).

2.Measure and record indoor wet bulb (WB) temperature using a sling psychrometer and the outdoor dry bulb (DB) temperature using a thermometer.
