Kaeser Screw Compressor AS31

Clean the filter mat every 100 to 300 service hours depending on the dust content of the intake air.

Switch off the compressor (see chapter 8.2).

Lock the main disconnect switch in the "off" position in accordance with applicable lock out/tag out procedures to ensure the compressor does not restart.

Open the snap fasteners (turn the flat-head screw with a screwdriver counter clock- wise 90*) and remove the holding frame.

Fit the holding frame and close the snap fasteners (turn the flat-head screw with a screwdriver clockwise 90° then press until the fasteners snap in).

Rinse the mat in warm water ( approximately 105°F), if necessary, use a mild detergent soap to rinse out oily dust. The mat can also be tapped, vacuum cleaned or blown out with compressed air (not in excess of 30 psig).

Attention!: If the mat is heavily soiled or has been cleaned often (maximum five times), replace it.;

Warning: Ensure the compressor unit is switched off and locked in the 'off' position before starting.

Vent the compressor unit before starting.

Open the left-hand maintenance and drive access doors.

Open the upper maintenance door and the drive guard.

Isolate the compressor from the compressed air system by closing the isolation shut-off valve.

Insert the maintenance hose into the hose coupling on the aftercooler.

Unscrew the pressure line of the pipework from the compressed air connection.

Attention!: Replace the run--in oil filter cartridge with a standard oil filter cartridge (supplied with the compressor) after approximately 200 operating hours.

It is recommended that the oil filter cartridge is replaced every 1000 to 2000 operating hours and always when the oil is changed.

Switch off the compressor with the control switch

Lock the main disconnect in the "off" position in accordance with applicable lock out/tag out procedures to ensure the compressor does not restart.

Lock the isolation shut-off valve in the "closed" position and vent all compressed air trapped between the compressor and the isolation shut-off valve in accordance with applicable lock out/ tag out procedures.

Open the upper maintenance and door and the drive guard.

Open the right-hand maintenance door.

Insert the maintenance hose - with the ball valve closed - in the hose coupling on the oil separator tank.

Check the oil level weekly through the oil sight glass when the compressor is shut down.

Is the oil level at the maximum level (center of the top oil sight glass)?

Is the compressor unit shut down?

Is the main disconnect locked in the 'off' position?

Is the isolation shut-off valve locked in the 'closed' position?

Is all compressed air vented between the compressor and the isolation shut-off valve?

Is the right-hand maintenance door open?

Does the pressure gauge on the oil separator tank indicate zero psig?

Warning: Non-observance of safety references can lead to accidents causing injury or damage to equipment.

The compressor unit starts automatically after a power failure if the line pressure is lower than the setting on the air pressure switch.

Do not operate the compressor with open maintenance doors as injury could occur from the drive belts and electrical equipment.

Remove all packaging materials, tools and transport securing devices on and in the compressor unit.

The operator of this compressor unit is responsible for its safe operating condition.

Do not operate this compressor unit in locations where heavy dust conditions, poisonous, or inflammable gases could exist.

Do not connect the compressor unit to a supply voltage other than that stated on the nameplate.

Install the compressor unit in a location not subject to freezing temperatures.

If exhaust ducting is provided, this must be at least the cross section of the cooler exhaust area in size and may not exceed the max. allowed pressure drop defined by the manufacturer.
