Sullivan-Palatek Industrial Air Compressor SP20-350

Warning: Follow 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.

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.

Wait until sump pressure reading is 0 psig.

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

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.

Follow 6.3 Stopping for Maintenance procedures (optional).

If the compressor is equipped with the optional canopy, remove the front left access door panel. The pressure control regulating valve is located behind this enclosure panel, to the right of the electrical control panel.

Tighten the adjusting screw on the pressure control regulating valve about one turn to remove the modulating control while adjusting the load and unload settings on the CPS.
