Cleaning Air-Cooled Cooling System
air compressor operating temperatures will be higher than
normal if the external passages between the fins of the
cooler cores become restricted with foreign material. Regular
cleaning of the cooler surfaces will support the reliable
operation of the air compressor system, improve the life of
the compressor coolant and improve overall compressor
efficiency. when performed frequently as determined by
site conditions and airborne contamination, more significant
cleaning or replacement may not be necessary.
1. stop the compressor.
2. Isolate the compressor from the system.
3. Press the emergency stop to vent the separator tank
and airend. fixed speed compressors can take more
than two minutes to fully de-pressurize once stopped.
4. Ensure that the main power disconnect switch is
locked off and tagged.
NOTICE
For any required lifting of air compressor parts or
required tools, always use the proper certified lifting
equipment, and employ sound working principles .
5. visually check the outside of the cooler cores to
determine the appropriate cleaning method detailed
as follows:
a. for loose dirt, dust and other light foreign material,
open the access panel on the cooler plenum. gently
blow compressed air across the cooler surface.
Repeat the process until the coolers are sufficiently
clean. Replace the access panels before returning the
compressor to service.
b. for thick, packed dirt, coolant or grease, or other
heavy material, the coolers will need to be removed
from the compressor for pressure washing. Ingersoll
Rand does Not support pressure washing coolers
when they are installed in the compressor due to
the dangers of spraying water in or around potential
electrical power sources. follow the steps below for
cooler removal.

Removing/ Installing Air-Cooled Cooler
to remove:
1. stop the compressor.
2. Isolate the compressor from the system.
3. Press the emergency stop to vent the separator tank
and airend. fixed speed compressors can take more
than two minutes to fully de-pressurize once stopped.
4. Ensure that the main power disconnect switch is
locked off and tagged.
NOTICE
For any required lifting of air compressor parts or
required tools, always use the proper certified lifting
equipment, and employ sound working principles .
5. drain the coolant from the coolant cooler by
removing the hex plug located at the lower side of
the coolant cooler. Place the straight end of the drain
hose in a suitable container. Install the other end of
the drain hose in the drain valve located at the lower
side of the coolant cooler. the coolant flows through
the drain hose automatically. after drainage, remove
the hose and close the valve.
6. Remove all hoses, pipes, and sensors from the coolers.
7. Remove the top panel (for Rs15-22ie, ne) or
Remove front, rear door and top panel (for Rs11-22i,
Rs15-22n).
8. Properly secure the cooler and remove four screws at
the upper side of the cooler.
9. Re-install the coolant drain plug to 16 Nm (12 ft-lb).
to install:
1. Carefully place the cooler in its proper location and
install four screws (gun tight).
2. Re-attach all hoses and pipes, and properly torque
according to the Parts Information manual.
3. Install the top panel.
4. Refill the compressor with coolant to the proper level,
following the process outlined in the “adding Coolant”
procedure.
