Assembly

Installation and Location

1. Install the compressor in a clean, dry, and well-ventilated area. The compressor should be located 12 to 18

inches away from a wall or any other obstruction that would interfere with the air flow through the fan-bladed

belt wheel.

2. Place the compressor on a firm, level surface. The compressor is designed with heat-dissipation fins, which

allow for proper cooling, Keep the fins and other parts, that collect dust or dirt, clean. A clean compressor

runs cooler and provides longer service. Do not place rags, containers, or other material on top of the

compressor which would obstruct ventilation openings for proper compressor operating temperature.

For Vertical Types:

For permanent installation, the compressor should be bolted to the floor through holes provided in the

compressor feet. Shims must be used to level the compressor before bolting it to the floor. Severe vibration will

result when the compressor is bolted down tightly, and the feet are not level. This can lead to welds cracking or

fatigue failure of the air receiver.

For Belt Types:

Install the triangular belt and adjust it so when pressure is applied at the centre, there is half an inch of slack.

NOTE: If the belt is installed too tightly, overloading of the motor will occur. This will cause the motor to overheat.

If the belt is installed too loosely, it will slip, and unstable operation and vibration will occur.

CAUTION: The rotating direction for the flywheel must follow the arrow shown on the belt guard.

Operation

Compressor Lubrication

NOTE: CHECK THE OIL QUANTITY AND QUALITY BEFORE OPERATING THE COMPRESSOR. DO

NOT ADD OR CHANGE OIL WHILE THE COMPRESSOR IS IN OPERATION. USE ONLY THE

RECOMMENDED SAE 20 OR 30 WEIGHT NON-DETERGENT OIL.

Compressor with Oil Level Gauge

1. Turn the oil-filling plug anti-clockwise, then pull it out.

2. The compressor is full when the oil level is between the “H” and “L” marks. Replace the oil filling plug.

3. ALWAYS KEEP THE OIL LEVEL BETWEEN THE “H” and “L” MARKS ON THE OIL GLASS.

Draining the Oil

1. Remove the oil drain plug. Allow oil to drain completely.

2. Replace the oil drain plug (it’s recommended to use a sealing compound or Teflon tape to avoid leakage).

3. Refill with the recommended oil to the proper level.

Before Operating the Compressor

1. Check to see that all nuts and bolts are securely fixed.

2. Check to see if the belt is installed properly, and with proper tension (except direct coupler types).

3. Check if the quantity and quality of oil is correct (see Compressor Lubrication).

4. Check if the compressor is secured on a strong, stable, and level base (for belt types only).

5. Check if the oil breather is clean (except direct coupler types).

6. If the air filter is dirty, have it replaced or cleaned.

7. Check if the flywheel can be turned easily and smoothly (except direct coupler types).

Initial Start-Up Procedure

1. Open the air receiver service valve to permit air to escape, preventing air pressure build-up in the air

receiver.

2. Plug-in the power supply cord (if applicable to your unit) into the mains power source.

3. Check fan blade rotation, if it is not spinning in the direction as indicated on the belt guard then your

electrician will need to reverse the polarity.

4. For electric air compressors, please use an electricity supply within ±5% of local voltage.

5. Run the compressor for a minimum of twenty (20) minutes in this no-load position to lubricate the bearings
