Prior to opening or removing panels or covers to work
inside a machine, ensure that:-
•
anyone entering the machine is aware of the reduced
level of protection and the additional hazards, including
hot surfaces and intermittently moving parts .
•
the machine cannot be started accidentally or otherwise .
Prior to attempting any maintenance work on a running
machine, ensure that:-
Only properly trained and competent persons should
undertake any maintenance tasks with the compressor
running or with electrical power connected .
•
the work carried out is limited to only those tasks which
require the machine to run .
•
the work carried out with safety protection devices
disabled or removed is limited to only those tasks
which require the machine to be running with safety
protection devices disabled or removed .
•
all hazards present are known (e .g . pressurised
components, electrically live components, removed
panels, covers and guards, extreme temperatures, inflow
and outflow of air, intermittentlymoving parts, safety
valve discharge etc .) .
•
appropriate personal protective equipment is worn .
•
loose clothing, jewellery, long hair etc . is made safe .
•
warning signs indicating that Maintenance Work is in
Progress are posted in a position that can be clearly
seen .
Upon completion of maintenance tasks and prior to
returning the machine into service, ensure that:-
•
the machine is suitably tested .
•
all guards and safety protection devices are refitted and
correctly working .
•
all panels are replaced, canopy and doors closed .
•
hazardous materials are effectively contained and
disposed of in a manner compliant with local or National
environmental protection codes .
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 untill 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) .

DANGER
WARNING
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 loaded) .
A . Correct at operating temperature
B . Too much
C . OK
D . Too little
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 .
Ensure that Ingersoll premium coolant is used . Failure
to do so will void manufacturer warrenty .
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 oil 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 .
