OPERATION AND MAINTENANCE MANUAL MAINTENANCE
WARNING
Do not under any circumstances open any
drain valve or remove components from the
compressor without rst ensuring that the
compressor is FULLY SHUT- DOWN, power
isolated and all air pressure relieved from the
system.
TOP UP COOLANT PROCEDURE
Slowly remove ll cap.
Pour coolant into spout untill spout almost
overows.
Replace and tighten oil ll cap.
Start unit for about 10 seconds (until coolant
drains out the bottom of the sight glass).
Slowly remove ll cap.
Re–ll into spout until spout almost overows.
Replace and tighten oil ll cap.
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
loaded).
Repeat this procedure to get coolant to proper level
when up to operating temperature.
When the unit is shut down, coolant will usually ll
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 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.
Stop the machine, electrically isolate and vent all
trapped pressure.
Place a suitable container close to the drain valve.
Slowly remove ll cap.
Remove plug from drain valve.
Open the drain valve and drain coolant into
container.
Close the drain valve.
Replace plug in drain valve.
Rell the machine following the ”top up coolant”
procedure above. After initial ll, 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.
Replace and tighten oil ll cap.
COOLANT FILTER CHANGE PROCEDURE
Stop the machine, electrically isolate and vent all
trapped pressure.
Loosen lter with the correct tool.
Remove the lter from the housing.
Place the old lter in a sealed bag and dispose of
in a safe way.
Clean the mating face of the housing taking care
to avoid any particles entering the machine.
Remove the new Ingersoll Rand replacement
lter from its protective package.
Apply a small amount of lubricant to the lter
seal.
Screw the new lter down until the seal makes
contact with the housing, then hand tighten a
further half turn.
Start the compressor and check for leaks.
AIR FILTER ELEMENT CHANGE PROCEDURE
Stop the machine, electrically isolate and vent all
trapped pressure.
Unscrew the retaining cap and withdraw the old
element.
Fit the new element.
Replace the retaining cap.
