Sullivan-Palatek Industrial Air Compressor SP20-250

Main power source disconnected and locked out?

Compressor isolated from the compressed air supply?

Sump pressure reading is 0 psig?

All manual drain valves within the area to be serviced are open?

Unit cooled down to safe temperature?

Compressor run long enough to reach normal operating temperatures?

Drain plug from the end of the drain line at the bottom of the sump tank removed?

The separator element should be replaced every 4,000 hours (or once a year) or if fault E:0809, A:2808 or A:4806 is shown on the microprocessor.

Refer to Figure 6-5. The separator element is located in the top side of the sump tank under the tank lid. To replace the element, access panels have been supplied in the roof. By opening the enclosure roof, overhead access and external light is available.

The following procedures should be followed before doing any maintenance on the compressor and will not be repeated in any of the maintenance procedures.

1. Per Occupational Safety & Health Administration (OSHA) regulation 1910.147: The Control of Hazardous Energy Source (Lockout/Tagout), disconnect and lockout the main power source. Display a sign in clear view at the main power switch stating that the compressor is being serviced.

2. Isolate the compressor from the compressed air supply by closing a manual shutoff valve downstream from the compressor. Display a sign in clear view at the shutoff valve that the compressor is being serviced. Be certain that a pressure relief valve is installed upstream of any isolation valve.

3. Wait until sump pressure reading is 0 psig.

4. Open all manual drain valves within the area to be serviced.

5. Wait for the unit to cool before starting to service. Temperatures of 125°F (52°C) can burn skin. Some surface temperatures exceed 250°F (121°C) when the compressor is operating and just after it is shut down.

Inspect solenoid valve, correct as needed

Tighten electrical connections, correct as needed

Verify gauge accuracy, correct as needed

Instructions for checking the compressor lubricant level

Shut down the compressor (or check before the compressor is turned on)

Wait two minutes after the compressor stops to allow the pressure to be relieved and the oil to settle

Observe the oil level in the fluid sightglass. The fluid sightglass should be full

While the compressor is running, the oil should be visible in the sightglass and the compressor not running hot

Note: Checked with compressor off - sightglass full. Checked while running - any level in sightglass and unit not running hot.

The air filter should be replaced every 2,000 hours or more often in severe or outside conditions or if fault A:2030 or A:4804 is shown on the microprocessor.

The inlet filter is a critical filter, protecting the compressor from exterior foreign materials. Keeping the inlet filter element clean will help maintain proper capacity rating of the compressor.

The following procedures should be followed before doing any maintenance on the compressor and will not be repeated in any of the maintenance procedures.
