PERIOD
MAINTENANCE
After 24 hours
Visual check of machine for any leaks, dust
build up or unusual noise/vibration.
Contact IR authorised distributor if in doubt
.
Daily
Check the coolant level and replenish if
necessary.
When the separator
Check the pressure differential.
element warning is
displayed.
Change the separator element if the
pressure drop is zero or exceeds 1 bar (15
p.s.i.g.)
First 150 hours
Change the coolant filter.
1 month
Check the operation of the high temperature
protection switch(es) (109
_
C standard).
1 month
Check the operation of the discharge
temperature sensor (109
o
C standard). The
sensor should alert at 106
o
C.
1 month
Check the cooler(s) for build up of foreign
matter. Clean if necessary by blowing out
with air or by pressure washing.
1 month
Check the operation of the float mechanism
in the moisture separator and clean if
necessary.
Each 3 months
Operate the safety valve manually to verify
that the valve mechanism is functioning
correctly and that a small amount of air is
released.
Each 3 months
Check all hoses for signs of deterioration,
cracks, hardening etc.
Each 2000 hours / 6
months
Change the coolant filter.
PERIOD
MAINTENANCE
2000 hours / 6
months
Take coolant sample for fluid analysis.
2000 hours / 6
months
Check scavenge screen for blockage, clean
if required.
1 year
Change the air filter element.
Replace the element sooner if the indicator
light flashes.
1 year/1000 hours or
as defined by local
or national
legislation.
Separator tank.
Fully inspect all external surfaces, welds and
fittings. Report any excessive corrosion,
mechanical or impact damage, leakage or
other deterioration.
4000 hours / 6
months
Check the operation of the blow down
solenoid valve for signs of fatigue. Renew
the seals if necessary.
2000 / 4000 hours
Lubricate the main motor bearings according
to information on the motor data plate.
If in doubt contact Ingersoll–Rand.
8000 hours / 2 years
Replace the ULTRA COOLANT at
whichever interval occurs first.
Also replace the separator element and
coolant filter.

Replace all hoses.
6 years/6000 hours
or as defined by
local or national
legislation.
Separator tank.
Remove the cover plate and any necessary
fittings. Clean the interior thoroughly and
inspect all internal surfaces and welds.
1 monthly intervals.
On water cooled and sea water cooled
models check the water input line strainer for
build up of foreign matter, clean if required
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.
NOTE:
1 If sacrificial zinc anode is 50% corroded it should be replaced.
2 Coastal/harbour waters can contain corrosive chemicals from pollution and may reduce anode/cooler life.
3 Effects of corrosion or erosion are specifically excluded from warranty considerations.
