WARNING
Do not under any circumstances open any drain valve or remove components from the compressor without first ensuring that the compressor is FULLY SHUT − DOWN, power isolated and all air pressure relieved from the system.
Check dryer pressure gauge and vent dryer lines to zero pressure before servicing.
TOP UP COOLANT PROCEDURE
The reservoir is designed to prevent overfill. With warm unit stopped in the normal way, the sight glass level should be at the midpoint of the glass. The level should not drop beyond the bottom of the sight glass when running with a steady load.
CAUTION
Ensure that SSR ULTRA coolant is used. Failure to do so will void manufacturers warranty.
COOLANT CHANGE PROCEDURE
It is better to drain the coolant immediately after the compressor has been operating as the liquid will drain more easily and any contaminant will still be in suspension.
1.Stop the machine, electrically isolate and vent all trapped pressure.
2.Place a suitable container close to the drain valve.
3.Slowly remove fill/vent cap.
4.Remove plug from drain valve.
5.Open the drain valve and drain coolant into container.
6.Close the drain valve.
7.Replace plug in drain valve.
8.Refill the machine following the ”top up coolant” procedure above. After initial fill, to purge any airlocks, the machine should be run for a few minutes before checking that the level is correct.
9.Top up as needed after running for five minutes.
10.Replace and tighten oil fill cap.
11.Dispose of waste properly.

COOLANT FILTER CHANGE PROCEDURE
1.Stop the machine, electrically isolate and vent all trapped pressure.
2.Loosen filter with the correct tool.
3.Remove the filter from the housing.
4.Place the old filter in a sealed bag and dispose of in a safe way.
5.Clean the mating face of the housing taking care to avoid any particles entering the machine.
6.Remove the new Ingersoll Rand replacement filter from its protective package.
7.Apply a small amount of lubricant to the filter seal.
8.Screw the new filter down until the seal makes contact with the housing, then hand tighten a further half turn.
9.Start the compressor and check for leaks.
AIR FILTER ELEMENT CHANGE PROCEDURE
1.Stop the machine, electrically isolate and vent all trapped pressure.
2.Unscrew the retaining cap and withdraw the old element.
3.Fit the new element.
4.Replace the retaining cap.
SEPARATOR CARTRIDGE CHANGE PROCEDURE
1.Stop the machine, electrically isolate and vent all trapped pressure.
2.Loosen separator cartridge with the correct tool.
3.Remove the cartridge from the housing; place it in a sealed bag and dispose of it safely.
4.Clean the mating face of the housing.
5.Remove the new Ingersoll Rand replacement cartridge from its protective package.
6.Apply a small amount of lubricant to the cartridge seal.
7.Screw the new cartridge down until the seal makes contact with the housing, then hand tighten a further half turn.
