Compressed air can be dangerous if incorrectly handled��
Before doing any work on the unit, ensure that all
pressure is vented from the system and that the machine
cannot be started accidentally��
CAUTION
Before beginning any work on the compressor,
open, lock and tag the main electrical disconnect
and close the isolation valve on the compressor
discharge�� Vent pressure from the unit by slowly
unscrewing the coolant fill cap one turn�� Unscrewing
the fill cap opens a vent hole, drilled in the cap,
allowing pressure to release to atmosphere�� Do not
remove the fill cap until all pressure has vented from
the unit�� Also vent piping by slightly opening the
drain valve�� When opening the drain valve or the
coolant fill cap, stand clear of the valve discharge
and wear appropriate eye protection��
Ensure that maintenance personnel are properly trained,
competent and have read the Maintenance Manuals��
Prior to attempting any maintenance work, ensure
that:-
•
all air pressure is fully discharged and isolated from
the system�� If the automatic blowdown valve is used
for this purpose, then allow enough time for it to
complete the operation��
•
the machine cannot be started accidently or
otherwise��
•
all residual electrical power sources (mains and
battery) are isolated��
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 accidently or
otherwise��
Prior to attempting any maintenance work on a
running machine, ensure that:-
DANGER
Only properly trained and competent persons
should undertake any maintanence 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��

MAINTENANCE
Upon completion of maintenance tasks and prior to
returning the machine into service, ensure that:-
•
•
•
•
The reservoir is designed to prevent overfill�� With warm
unit stopped in the normal way, the sight tube level
should be within 15 mm (0��6 in) of the top of the green
strip�� The level should not drop beyond the bottom of the
sight tube when running with a steady load��
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��
•
all hazards present are known (e��g�� pressurised
components, electrically live components, removed
panels, covers and guards, extreme temperatures,
inflow and outflow of air, intermittently moving
parts, safety valve discharge etc��)��
•
appropriate personal protective equipment is worn��
•
loose clothing, jewelry, 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��
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 code
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
CAUTION
Ensure that Ingersoll Rand premium coolant is used��
Failure to do so will void manufacturers warranty��
COOLANT CHANGE PROCEDURE
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��
