II. LUBRICATION

A. Compressors

Each compressor is charged with the correct amount of oil at the factory.

B. Fan Motor Bearings

Fan motor bearings are of the permanently lubricated type. No further lubrication is required. No lubrication of con- denser or evaporator fan motors is required.

III. BLOWER BELT ADJUSTMENT

Inspect blower belt for wear, proper belt tension, and pulley alignment as conditions require or at the beginning of each heating and air conditioning season.

Refer to Step 9 — Adjust Evaporator-Fan Speed on page 24 for adjustment and alignment procedures.

Check belt tension at least once each heating or cooling sea- son or as conditions require. Adjust as required.

IV. MANUAL OUTDOOR-AIR DAMPER

If outdoor-air damper blade adjustment is required, see Manual Outdoor-Air Damper section on page 14.

V. ECONOMI$ER+ ADJUSTMENT

Refer to Optional EconoMi$er+ section on page 15.

VI. CONDENSER-FAN ADJUSTMENT (Fig. 40)

Shut off unit power supply. Remove condenser-fan assembly (grille, motor, and fan) and loosen fan hub setscrews. Adjust fan height as shown in Fig. 40. Tighten setscrews and replace condenser-fan assembly.

VII. REFRIGERANT CHARGE

Amount of refrigerant charge is listed on unit nameplate (also refer to Table 1). Compressor must run a minimum of 10 minutes before adjusting or checking charge.

Unit panels must be in place when unit is operating during charging procedure.

Fig. 40 — Condenser-Fan Adjustment

A. No Charge

Use standard evacuating techniques. After evacuating sys- tem, to 500 microns, weigh in the specified amount of refrig- erant. (Refer to Table 1.)

B. Low-Charge Cooling

Using Cooling Charging Charts, Fig. 41-44, vary refrigerant until the conditions of the appropriate chart are met. Note the charging charts are different from type normally used. Charts are based on charging the units to the correct super- heat for the various operating conditions. Accurate pressure gage and temperature sensing device are required. Do not use pocket type thermometers for measuring surface temper- atures as they are not designed for this type of measure- ment. Connect the pressure gage to the service port on the suction line. Mount the temperature sensing device on the suction line and insulate it so that outdoor ambient tempera- ture does not affect the reading. Indoor-air cfm must be within the normal operating range of the unit.

C. To Use Cooling Charging Chart

Take the outdoor ambient temperature and read the suction pressure gage. Refer to chart to determine what suction tem- perature should be. If suction temperature is high, add refrigerant. If suction temperature is low, carefully recover some of the charge. Recheck the suction pressure as charge is adjusted.

VIII. FLUE GAS PASSAGEWAYS

To inspect the flue collector box and upper areas of the heat exchanger:

1.Remove the combustion blower wheel and motor assembly according to directions in Combustion-Air Blower section on page 49.

2.Remove the flue cover to inspect the heat exchanger.

3.Clean all surfaces as required using a wire brush.
