10.0 MAINTENANCE

10.4 ROUTINE MAINTENANCE

This section refers to the various components which require periodic maintenance and replacement.

For all other maintenance, contact your local Ingersoll Rand office, Distributor or Air Center.

Refer to safety information and maintenance procedures prior to carrying out any of the maintenance in the following sections.

Prior to starting

Coolant level checking procedure

The coolant level should be checked daily. A coolant level sight glass is located on the side of the separator tank and while the machine is running on load, coolant should always be visible in the sight glass. The normal position is half way.

Stop the machine and ensure coolant is still visible in the sight glass.

Adding coolant

Run the compressor for a minimum of 40 seconds, the coolant level should be visible in the sight glass. If not, stop the compressor, depressurize by isolating the compressor from the system, pressing the emergency stop to vent the separator tank & airend & then slowly unscrew the coolant fill plug to verify all pressure has been released and add coolant. Replace the coolant fill plug, restart the compressor and recheck the coolant level. Repeat until the coolant level is visible in the sight glass with the compressor both running and stopped.

Do not add coolant through the intake of the compressor, as this can result in overfilling, saturation of the separator filter element, and coolant carry−over downstream.

danger

Under no circumstance should the compressor be operated with the coolant fill plug removed.

Coolant change procedure

warning

The coolant filter and coolant may be hot!

The compressor features a ’no drip’ coolant drain feature which requires no special tools and minimizes the risk of coolant spillage.

It is better to drain the coolant immediately after the compressor has been operating as the liquid will drain faster and any contaminant will still be in suspension

Remove the cap from the drain valve located at the front of the separator vessel.

Place a suitable container close to the drain valve.

Screw the coolant drain hose onto the drain valve. As the threads engage, the valve will automatically open and the coolant will drain.

Remove the drain hose. The valve will automatically close and seal.

Replace the cap on the drain valve.

For a complete drain, remove the plug near the vessel inlet flange and replace when complete.

Replace the coolant filter element.

Refill with correct quantity of coolant. See 8.0 General Information.
