Changing Coolant Filter


1. Remove drain plug from bottom of filter housing and drain coolant.
2. Loosen the filter housing.
3. Remove the element from the housing.
4. Place the old element in a sealed bag and dispose of in a safe way.
5. Remove the new replacement element from its protective package.
6. Apply a small amount of coolant to the element seal.
7. Install new replacement element into the filter housing.
8. Screw the housing to the filter head and tighten to the torque
specified on the housing.
9. Reinstall drain plug.
10. Start the compressor, check for leaks and check the coolant level.

Checking Separator Element


With the compressor running on load, check the separator differential
pressure via the controller. It will be necessary to change the element if the
differential pressure equals zero or exceeds 1 bar (15 psig).

Changing Separator Element


For R30-37, separator cartridges change procedure is as follows,
1. Stop the machine, electrically isolate and vent all trapped pressure.
2. Loosen separator cartridges with the correct tool.
3. Remove the cartridges from the housing; place in a sealed bag and
dispose of safely.
4. Clean the mating faces of the housing.
5. Remove the new Ingersoll Rand replacement cartridges from
protective package.
6. Apply a small amount of lubricant to the cartridge seal.
7. Screw the new cartridges down until the seal makes contact with
the housing, then hand tighten a further half turn.
8. Start the compressor and check for leaks.

For R37e-160, separator element change procedure is as follows,
1. Remove the fitting that holds the scavenge tube into the tank and
withdraw the tube assembly.
2. Disconnect the piping from the tank cover. Tag the lines if required.
Remove all the bolts securing the cover to the tank except the bolt
opposite the pivot bolt which should be left engaged by
2-3 threads with at least 6.5 mm (0.25 in) clearance from the screw
head to the cover. Rotate the jacking bolt clockwise until the cover
lifts off the tank at least 2 mm (0.08 in) all the way around the tank.
Remove the remaining bolt. The cover can now be rotated to allow
access to inside the tank.
3. Carefully lift the separator element up and out of the tank. Discard
the faulty element.
4. Clean the sealing surface on both the tank and its cover. Check the
tank to be absolutely certain that no foreign objects such as rags or
tools have been allowed to fall into the tank. Lubricate a thin layer
of coolant on the separator gasket top and bottom before installing
a replacement element down into the tank after checking the new
element seal for possible damage. Center the element within the
tank ensuring that it is fully seated in the sealing groove. Rotate the
tank cover back into position taking care not to damage the seal,
and locate the cover using two bolts but do not tighten down.
5. Loosen the jacking bolt to fully disengage the threads and tighten
the cover bolts in a cross-pattern to prevent over-tightening one
side of the cover. An improperly tightened cover will likely result in
a leak.
Unscrew the jacking bolt sufficiently to ensure that the cover can be
fully tightened down without imparting any stress onto the jacking
points . Tighten down the cover bolt to 81 N m (60 ft lb) for 75 kW
and smaller compressors or 200 N m (150 ft lb) for 90 kW and larger
compressors . Refer to Figure 3 for the tightening sequence of the
bolts .
6. Inspect the tank scavenge screen and orifice. Clean if necessary
following the instructions below.
7. Install the scavenge tube down into the tank until the tube just
touches the separator element and then raise it 3 mm (0.125 in).
Tighten fittings.
Take extreme caution to not force the scavenge tube into the tank .
This could potentially damage the separator element .
8. Install the piping in the original position.
