Ingersoll Rand Air Compressor R132IU-7.5

Coolant visible in the sight glass while machine is running on load?

Coolant level is between the middle and the top of the green section of the sight glass?

Run the compressor for a minimum of 40 seconds before stopping?

Add coolant until the level is up to the mid-point of the sight glass?

Visual check of machine for any leaks?

Visual check of machine for dust build up?

Visual check of machine for unusual noise/vibration?

Contact IR authorised distributor if in doubt.

NOTE: On some sea water cooled models the oil cooler and after cooler are fitted with sacrificial zinc anodes (pencils) that are located in the end bonnets of the coolers. These sacrificial zinc anodes should be checked after the first 50 hours of operation to determine if corrosive conditions exist. If satisfactory this interval may be extended to 500 hours.

Is the sacrificial zinc anode less than 50% corroded?

If sacrificial zinc anode is 50% corroded it should be replaced.

Is the operation in coastal/harbour waters?

Coastal/harbour waters can contain corrosive chemicals from pollution and may reduce anode/cooler life.

Effects of corrosion or erosion are specifically excluded from warranty considerations.
