9. Using a funnel, top off the level with new coolant.
The proper level is at the top of the fill port.
10. Replace fill plug.
11. Start unit and check for leaks.
Do not add coolant through the intake of the compres-
sor, as this can result in overfilling, saturation of the
separator filter element, and coolant carry-over down-
stream.
4.11 COOLANT CHANGE
Before beginning any work on the compressor,
open, lock and tag the main electrical disconnect
and close the isolation valve on the compressor
discharge. Wait 2 minutes after stopping to allow
internal pressure to dissipate. Vent residual pres-
sure from the unit by slowly unscrewing the
coolant fill plug one turn. Unscrewing the fill plug
opens a vent hole, drilled in the plug, allowing the
pressure to release to atmosphere (See Figure 4.3-
1). A slight mist or oil droplets may be visible dur-
ing venting. Do not remove fill plug until all pres-
sure has vented from the unit. Also vent piping by
slightly opening the drip leg valve . When opening
the drain valve or removing the coolant fill plug,
stand clear of the valve discharge, wear work
gloves and appropriate eye protection.
SPECIAL TOOLS
Suitable clean drain pan or container to hold approxi-
mately 3.6 gal. (13.5 L) of coolant drained from unit.
A quantity of proper coolant sufficient to refill the
coolant level in the compressor.
One genuine IR replacement coolant filter of the prop-
er type for the unit.
The coolant should be drained soon after the com-
pressor has been shut down. When the coolant is
warm, the drainage will be more complete and any
particles in suspension in the coolant will be carried
out with the coolant.
1. Place a clean pan under the drain plug.
2. Remove drain plug (See Figure 4.11-1) and allow
coolant to drain from the tube separator.
3. Using a filter wrench, remove the coolant filter.
Remember that the filter and coolant may be hot!
4. Discard the old filter.
5. Wipe the sealing surface of the filter head with a
clean lint-free rag to prevent entry of dirt into the sys-
tem.
6. Remove the replacement filter from its protective
package.
7. Apply a small amount of clean coolant on the rubber
seal of the filter.
8. Screw element on until the seal makes contact with
the seat on the filter header. Tighten approximately
one half to three quarters turns additional.
9. Install and tighten the coolant drain plug.
10. Remove coolant fill plug (See Figure 4.10-1).
11. Using a funnel, fill unit with new coolant. The prop-
er level is even with the top of the fill port.
12. Replace fill plug.
13. Start unit and check for leaks.
Do not add coolant through the intake of the compres-
sor as this can result in overfilling, saturation of the
separator filter element and coolant carry-over down-
stream.
