10.4 ROUTINE MAINTENANCE

This section refers to the various components which
require periodic maintenance and replacement.
For all other maintenance, contact your local Ingersoll
Rand office, Distributor or Air Center.
Refer to safety information and maintenance
procedures prior to carrying out any of the
maintenance in the following sections.
Prior to starting
Coolant level checking procedure
The coolant level should be checked daily. A coolant
level sight glass is located on the side of the
separator tank and while the machine is running on
load, coolant should always be visible in the sight
glass. The normal position is half way.
Stop the machine and ensure coolant is still visible in
the sight glass.
Adding coolant
Run the compressor for a minimum of 40 seconds,
the coolant level should be visible in the sight glass.
If not, stop the compressor, depressurize by isolating
the compressor from the system, pressing the
emergency stop to vent the separator tank & airend &
then slowly unscrew the coolant fill plug to verify all
pressure has been released and add coolant.
Replace the coolant fill plug, restart the compressor
and recheck the coolant level. Repeat until the
coolant level is visible in the sight glass with the
compressor both running and stopped.
Do not add coolant through the intake of the
compressor, as this can result in overfilling, saturation
of the separator filter element, and coolant carry−over
downstream.
10.0 MAINTENANCE
IRN37−160K−CC & IRN50−200H−CC & IRN75−160K−2S & IRN100−200H−2S & IRN250−300H−2S
DANGER
Under no circumstance should the compressor
be operated with the coolant fill plug removed.
Coolant change procedure
WARNING
The coolant filter and coolant may be hot!
The compressor features a 'no drip' coolant drain
feature which requires no special tools and minimizes
the risk of coolant spillage.
It is better to drain the coolant immediately after the
compressor has been operating as the liquid will
drain faster and any contaminant will still be in
suspension.
S Remove the cap from the drain valve located at
the front of the separator vessel.
S
Place a suitable container close to the drain valve.
S
Screw the coolant drain hose onto the drain valve.
As the threads engage, the valve will automatically
open and the coolant will drain.
S
Remove the drain hose. The valve will
automatically close and seal.
S
Replace the cap on the drain valve.
S
For a complete drain, remove the plug near the
vessel inlet flange and replace when complete.
S
Replace the coolant filter element.
S
Refill with correct quantity of coolant. See 8.0
