Sullair Portable Air Compressor 900H

Refer to Figure 5-4. Air filter maintenance should be performed when indicated on instrument panel. The air filters are both equipped with a primary element and secondary element each.

The secondary element must be replaced after every third primary element change. DO NOT reconnect the secondary element once it is removed.

1. Clean the exterior of the air filter housing.

2. Remove the cover/element assembly by loosening the wingnut securing the cover/ element assembly.

3. Remove the cover/element assembly from the housing by unscrewing the wingnut.

4. Clean the interior of the housing by using a damp cloth. DO NOT blow out dirt with compressed air as this may introduce dust downstream of the filter.

5. When it becomes necessary to remove the secondary element, pull the element out of the housing.

Each day, walk around the air compressor and inspect for leaks, loose or missing parts, damaged parts or parts out of adjustment. Perform all recommended daily maintenance. Inspect for torn, frayed, blistered or otherwise deteriorated and degraded hoses. Replace as required.

DO NOT remove caps, plugs and/or other components when compressor is running or pressurized. Stop compressor and relieve all internal pressure before doing so.

Prior to starting the compressor, it is necessary to perform a daily inspection. Perform the following maintenance operations to prevent unnecessary problems.

1. Check the fluid level in the compressor receiver tank. Should the level be low, simply add the necessary amount. If the addition of fluid becomes too frequent, a simple problem has developed which is causing this excessive loss. Refer to Section 5.12: Troubleshooting guide on page 65 under "Excessive Compressor Fluid Consumption" for a probable cause and remedy.

2. Drain water from the fuel/water separator.

3. Check the fuel level in the fuel tank.

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?

Is the valve closed when draining is complete?

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

If not using Sullair AWF, replace the fluid filter element only.

Compressor shut off and system pressure relieved?

Suitable container positioned beneath the elements to catch fluid drainage?

Elements removed using a suitable tool?

Each element rotated counterclockwise to remove?

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.

Enter the hours since the last coolant change

Dispose of fluids in accordance with applicable federal, state and local regulations.
