SERVICE AND TROUBLESHOOTING

SERVICE HINTS

1.Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces air flow through the system which shortens equipment service life as well as increasing operating costs.

2.Check all power fuses or circuit breakers to be sure that they are the correct rating.

3.Periodic cleaning of the outdoor coil to permit full and unrestricted airflow circulation is essential.

PRESSURE SERVICE PORTS

High and low pressure service ports are installed on all units so that the system operating pressures can be observed. Pressure tables can be found later in this manual covering all models on cooling cycle. It is imperative to match the correct pressure table to the unit by model number.

REFRIGERANT CHARGE

The correct system R-22 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 11.

TABLE 11

SUCTION LINE TEMPERATURES

	Rated	95° OD	82° OD
Model	Airflow	Temperature	Temperature

P1124A2	800	56 - 58	63 - 65

P1224A1	800	56 - 58	63 - 65
P1130A2	1125	56 - 58	63 - 65

P1230A1	1000	56 - 58	63 - 65
P1136A2	1250	57 - 59	58 - 60

P1236A1	1100	57 - 59	58 - 60
P1142A3	1400	57 - 59	58 - 60

P1242A1	1400	57 - 59	58 - 60
P1148A2	1550	54 - 57	58 - 60

P1248A2	1550	53 - 55	56 - 58
P1060A1	1700	47 - 49	54 - 56

The above suction line temperatures are based upon 80°F dry bulb/67°F wet bulb (50% RH) temperature and rated airflow across the evaporator during cooling cycle.

FAN BLADE SETTINGS

Shown in Figure 10 are the correct fan blade setting dimensions for proper air delivery across the outdoor coil.

Any service work requiring removal or adjustment in the fan and/or motor area will require that the dimensions below be checked and blade adjusted in or out on the motor shaft accordingly.
