Sullivan Air Compressor 40DG

Open and lock out main disconnect

Disconnect main air line to aftercooler

Disconnect control air. Pick up line @ MVP

Disconnect oil return scavenge line

Unbolt cover in a diagonal criss-cross pattern

Remove cover and separator element

Drain lubricoolant and clean interior of oil separation tank if element appears dirty

Clean flange and cover surfaces. (If rusty, clean thoroughly and paint with high temperature paint)

Coat surfaces of gasket lightly with lithium grease

1. Change compressor lubricoolant filter.

2. Take sample of lubricoolant and submit for analysis if operating in severe environment. (Ex: chemical fumes, oxidizing elements, fine dust)

• When using Palasyn 45: Every 4,000 hours or once a year, whichever occurs first

- Drain lubricoolant and replace with a fresh charge. Inspect interior of tank. Clean tank if any build-up of deposits is present. This may have to be done sooner depending upon results of lubricoolant analysis. Replace air/oil separator element and the air filter element.

• When using Pallube 32p: Every 8,000 hours

- Change Pallube 32p lubricoolant and inspect tank interior. Replace air/oil separator element. Replace air and oil filter.

• When using Pal Extra 44: Every 10,000 hours

- Change AFX 32 and inspect tank interior. Replace air/oil separator, as well as air and oil filter element.;

Open and lock out main disconnect.

Remove end cover by operating snap-catch to release cover.

Remove air filter element, taking care to prevent dirt, which has collected on the outer surface of the element from falling into the open compressor inlet. Wipe dust from inside of housing with a damp cloth.

NOTE: To minimize downtime, it is recommended that a spare element be kept on hand. Check model and serial number for proper element number.

NOTE: An optional safety element is available. For fine dust conditions, a smaller micron element is also available.

Snap the end cover back on once the filter element has been replaced.

- Two capacity control features are incorporated in the Sullivan-Palatek compressors. The control pressure switch (CPS) will cycle the compressor between loaded and unloaded operation. This switch should be set so that the compressor loads when the line pressure falls to the lowest pressure required to operate plant equipment, and unloads the compressor at some higher pressure (normally about 10 psi above load pressure.)

- The other means of controlling compressor out-put is by means of the modulating or regulating valve. The modulating valve will proportionally pinch shut the inlet valve depending upon the existing line pressure.

To set the compressor controls, follow the following steps: 1. Turn in on modulating valve adjusting screw about one turn (this is to remove this control while setting the CPS).

2. Adjust the cut-out pressure by turning the top adjusting screw (CW to raise the pressure, CCW to lower).

3. Adjust the cut-in pressure by turning the lower adjusting screw. CW to decrease the cut-in; CCW to increase the cut-in pressure.

4. One the CPS has been set to the desired valves, the modulating valve must be reset. Loosen the adjusting screw until air is being vented from regulator at a pressure about 5 psi below the set cut-out pressure of the CPS. Lock adjusting screw in place.

- Note that the selector switch on the electrical box has three settings; ‘Run’, “Off/Reset”, and ‘Auto’. In the ‘Auto’ position the compressor will shut off after running unloaded for 15 minutes. In the ‘Run’ mode the compressor motor is never shut off.

- For maximum efficiency of operation, if it is intended to operate the compressor in the ‘Auto’ mode, the pressure settings should have as large a differential as practical to allow the compressor to time out and shut off (consult factory for other optional energy saving options.);

Open and lockout main disconnect.

Relieve all internal system pressure.

Using a strap wrench, remove spin-on oil filter element. (P/N 00520-017)

Spread a thin film of grease on the gasket.

Install element by hand until gasket touches the filter head.

Check for leaks after compressor is up to temperature.
