. 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.
. 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, 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.
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
The reservoir is designed to prevent overfill. With warm unit
stopped in the normal way, coolant should be at the top of the sight
glass. The level should not drop beyond the bottom of the sight glass
when running with steady load.
CAUTION
Ensure that SSR ULTRA 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/vent 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.
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.
AIR FILTER ELEMENT CHANGE PROCEDURE
1. Stop the machine, electrically isolate and vent all trapped pressure.
2. Unclip the retaining cap and withdraw the old element.
3. Fit the new element.
4. Replace the retaining cap.
