10.0 MAINTENANCE

No Loss Drain Trap (where fitted) Check / Cleaning

Remove the four socket head screws then carefully split the trap. Clean and inspect all internal parts with particular attention to the water level sensor(s).

If the stainless steel strainer mesh is blocked, remove it and clean in a weak detergent solution.

Replace any defective parts (see parts manual for repair kit).

Re−assemble and later, with machine running, check that condensate is expelled at regular period and no alarms are signaled on trap or on INTELLISYS display.

Fluid and Vibration Monitoring

Ingersoll Rand recommends incorporating predictive maintenance, specifically the use of coolant and vibration analysis, into all Preventative Maintenance programs. Predictive Maintenance is designed to increase system reliability and prevent costly downtime. Through the use of sophisticated diagnostic tools, including fluid, vibration, and optional air analysis, IR Certified Service Technicians can identify and correct potential problems BEFORE they can cause expensive unscheduled downtime.

How does predictive analysis work? By establishing an initial baseline for normal operation, and then regularly monitoring fluid and vibration conditions, any sudden deviation or significant increase from this baseline can be identified and investigated to pinpoint the cause. More quickly diagnosing potential problems can directly save money by preventing costly failures and reducing or eliminating downtime. In addition, regular condition monitoring also helps to maximize the time between expensive preventative maintenance intervals, such as component rebuilds and coolant changes.

Coolant Sampling Procedure

Bring unit up to operating temperature. Draw sample, using pump kit, from separator tank port. DO NOT draw sample from drain port or oil filter. Use a new hose on pump for each sample, failure to do this can give false readings.
