Sullivan-Palatek Industrial Air Compressor SP20-125

The oil filter should be replaced after the first 50 hours of operation and then every 1,000 hours (or quarterly) or if fault A:2020 or A:4807 is shown on the microprocessor.

The fluid filter is located between the thermal valve and the unit injection port. The SP models have the filter mounted with the filter elements located on the top side. Once the pressure in the system has been completely depleted, most of if not all of the fluid in the elements have drained out making replacement simpler.

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 return line flow, Correct as needed

Note: Compressor running fully loaded

The oil level should be checked daily.

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.

Sign off on the daily compressor lubricant level check

Remove the scavenger line between the tank lid and the top of the sight glass

Disconnect tube lines connected to the lid or MPV. Mark the ends for proper reinstallation.
