ROUTINE MAINTENANCE
This section refers to the various components which require
periodic maintenance and replacement.
It should be noted that the intervals between service
requirement may be signicantly reduced as a consequence
of poor operating environment. This would include eects of
atmospheric contamination and extremes of temperature.
The SERVICE/MAINTENANCE CHART indicates the
various components’ descriptions and the intervals when
maintenance has to take place. Oil capacities, etc., can be
found in the PRODUCT INFORMATION SHEET.
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.
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 ll cap one turn. Unscrewing the ll cap opens
a vent hole, drilled in the cap, allowing pressure to
release to atmosphere. Do not remove the ll 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 ll 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 accidentally or otherwise.
all residual electrical power sources (mains and battery)
are isolated.
