Ingersoll Rand Air Compressor ups-40-125bp

Isolate the housing from the air supply

Fully depressurize in drain bowl

If pressure has not been completely released from the housing, air will escape from the warning hole giving an audible alarm. Screw back bowl and repeat instruction 2 before attempting again.

Check condition of bowl seal and replace if necessary

Repressurize and check for leaks

If leaks occur they will most probably be from the bowl ‘O’ ring. Depressurize housing and remove ‘O’ ring as stated above and inspect and clean. Ensure that mating surfaces are clean and then refit ‘O’ ring and repressurize.

1. Stop the machine, electrically isolate and vent all trapped pressure.

2. Loosen filter with the correct tool.

3. Remove the filter from the housing.

4. Place the old filter in a sealed bag and dispose of in a safe way.

5. Clean the mating face of the housing taking care to avoid any particles entering the machine.

6. Remove the new Ingersoll Rand replacement filter from its protective package.

7. Apply a small amount of lubricant to the filter seal.

- Change drive belt and gas spring.

1. Stop the machine, electrically isolate and vent all trapped pressure.

2. Remove the side cover from the machine.

3. Fit a 1/2” square drive wrench in the tension cam located above the airend (access from front door). Turn clockwise 1/4 turn to Position II to release gas strut tension on the belts.

4. Using a small screwdriver under the spring clip, ease the ball ends off the spherical studs at the ends of the gas strut.

5. Replace the gas strut and the studs at the same time by removing and replacing the studs then pushing the new gas strut firmly onto the studs until it clicks into place.

6. Turn the tension cam clockwise 1/4 turn to Position III to raise and support the airend. Place a block of wood or similar under the separator tank for support.

7. Replace the belts from the left side of the machine.

- Remove and clean package pre–filter, replace if needed.

- Check the cooler(s) for build up of foreign matter. Clean if necessary by blowing out with air or by pressure washing.

1. Stop the machine, electrically isolate and vent all trapped pressure.

2. Remove the top cover to obtain access to the cooler.

- Check hoses and fittings for leaks – tighten as required.;

Ensure that the compressor is isolated from the compressed air system by closing the isolation valve and venting pressure from the drip leg.

Ensure that the main power disconnect switch is locked open and tagged.

Put the compressor in the MODULATION mode by placing control selector switch SS in the “MODULATION” position (Non–Intellisys models).

Remove 1/4” plastic plug from the tee (18) in the regulator valve Connect a pressure gauge to this port.

Loosen the adjustment screw locknut and back out adjusting screw 3 turns See Figure 2.

Put the main power disconnect switch in the ON position.

Open the isolation valve and start the compressor.

Adjust the isolation valve to bring the discharge air pressure to the rated discharge pressure (100, 125, 140, or 200 psig).

While maintaining the rated discharge pressure, turn the adjustment screw on the modulation valve (see Figure 2) so that the test pressure gauge reads: 30 psig for modulate 60% cfm.
