Sullair Portable Air Compressor 600H

Refer to Figure 5-6. When fluid carry-over is evident after the fluid return-line strainer and orifice, as well as the blowdown valve diaphragm, have been inspected and found to be in satisfactory condition, or if the separator restriction gauge reads in excess of 10 psig (0.7 bar), separator element replacement is necessary.

Remove all piping connected to the receiver tank cover to allow removal (return line, service line, etc.)

Remove the fluid return line from the fitting in the cover.

Remove the twelve (12) 5/8 x 2.25 in cap-screws and lock washers and lift the cover from the receiver tank with the minimum pressure/check valve in place.

Scrape the old gasket material from the cover and the flange on the receiver tank. Be sure to keep all scrapings from falling inside the tank.

Make sure grounding staples are attached to separator gasket. DO NOT REMOVE STAPLES.

Replace the receiver tank cover. Install the twelve (12) 5/8 x 2.25 in capscrews and lock washers in finger-tight, then gradually tighten in a crisscross pattern in 4 to 5 steps.; Always tighten the capscrews alternately at opposite sides of the cover. Never tighten capscrews adjacent to each other. Torque capscrews to 112 to 127 ft.lbs (151 to 172 N-m).

5.7 Maintenance every 300 hours

When not using Sullair AWF®, change the compressor fluid and replace the fluid filter element. Refer to Main Fluid Filter Servicing on page 62.

5.11.4 Main fluid filter servicing

Refer to Figure 5-3. The main fluid filters are located schematically in the coolant line between the receiver tank and the compressor unit. The main filter elements are replaceable. For installation of the filter elements, follow the procedure explained below:

1. The compressor MUST be shut off and system pressure MUST be relieved.

2. Position a suitable container beneath the elements to catch fluid drainage.

3. Remove elements using a suitable tool.

4. Rotate each element counterclockwise to remove.

5. Remove element and discard. These elements are not cleanable.

Clean the return line orifice and strainer

Repack the wheel bearings on wheel-mounted units

Warning: Only use the recommended coolant for the machine. Do not mix different color coolants.

Select the color of the coolant used

Is the coolant the same as what is in the cooling system?

If unsure of the coolant type, flush the system until the flushed water is clear.

Select the type of coolant to be used

CAUTION: The radiator and engine cooling system must be drained and flushed periodically.

If Sullair AWF® is used, proceed with the following steps

Compressor fluid change procedure

Has the compressor been warmed up for 5 to 10 minutes?

Is the compressor off and all internal pressure relieved?

Has the fluid been drained by opening the appropriate drain valve?

Has the valve been closed after draining?

Has the compressor fluid been changed and the fluid filter element replaced?
