10.0 MAINTENANCE
COOLANT DRAIN
CAUTION
Do not mix coolant types. Use only coolant specified
by Ingersoll Rand
Start the compressor and check for leaks.
Check the coolant level, refilling if necessary.
Dispose of waste coolant in accordance with local
and governmental regulations.
Standard air compressors are factory filled with
SSR Ultra coolant, it is recommended to perform
a coolant analysis every 2000 hours or 3 months
to monitor condition and determine when to
change the coolant, if analysis is not performed, the
recommended coolant change interval is 8000 hours
or 2 years, whichever comes first.
NOTICE
Shorter coolant change intervals may be necessary
if the compressor is operated in adverse conditions.
Food Grade Coolant option
SSR Food Grade Coolant is a polyalphaolefin base
coolant. It is recommended to have samples of the
coolant analysed every 500 hours or each month to
determine when coolant should be changed.
If analysis is not performed, coolant should be
changed after 2000 hours or every 6 months when
utilizing the X-Tend food grade filter supplied with
the machine.
For units running food grade coolant without the X-
Tend food grade filter, the change interval should be
1000 hours or 6 months, whichever comes first.

Coolant Sampling Procedure
Bring unit up to operating temperature. Draw sample,
using pump kit, from separator tank port. DO NOT draw
sample from drain port or oil filter. Use a new hose on
pump for each sample, failure to do this can give false
readings.
