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.
TOP UP COOLANT PROCEDURE
1 Slowly remove fill cap.
2 Pour coolant into spout until spout almost overflows.
3. Replace and tighten oil fill cap.
4. Start unit for about 10 seconds (until coolant drains out the bottom
of the sight glass).
5. Slowly remove fill cap.
6. Re–fill into spout until spout almost overflows.
7. Replace and tighten oil fill cap.
8. Run unit.
Note:
Coolant level is correct when a unit is showing coolant in bottom half
of sight glass when up to operating temperature (ten minutes running

MAINTENANCE

Repeat this procedure to get coolant to proper level when up to
operating temperature.
When the unit is shut down, coolant will usually fill up sight glass.
Do not adjust level based on level at shutdown. Proper level is always
set for a running unit at operating temperature.
CAUTION
Ensure that SSR ULTRA–PLUS 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 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 cycling between load and no load, before checking that the
level is correct.
9. Replace and tighten fill cap.
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.
