SSR UP Series Maintenance Schedule
PERIOD MAINTENANCE
Each 24 hours
operation
Check the coolant level and replenish if
necessary.
Visual check of
machine for any
leaks, dust build up
or unusual noise or
vibration
Report immediately, contact Ingersoll Rand
authorized distributor for assistance if in
doubt
When compressor
is receiver mounted
Drain air receiver of condensate, or check
that automatic drain is operating
Visual check
condition of
package pre–filter
Blow clean if needed
If the air filter
indicator locks into
red position before
the 2000 hour/1 year
change out period
Check the Condition of filter. Change the air
filter if needed. Dusty environments require
more frequent replacement.
(Indicator should be checked with unit
stopped)
First 150 hours Change the coolant filter.
Each month or 100
hours
Remove and clean package pre–filter,
replace if needed
Check the cooler(s) for build up of foreign
matter. Clean if necessary by blowing out
with air or by pressure washing.
Check hoses and fittings for leaks – tighten
as required.
Each 2000 hours / 6
months
Take coolant sample for fluid analysis.

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 significantly reduced as a consequence of poor operating
environment. This would include effects 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 GENERAL
INFORMATION section of this manual.
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.
Strip, clean and re–Grease motor bearings
