2.
Disconnect the supply gas line from the supply coupling on the compressor. Screw a dust
plug into the disconnected gas line.
NOTE
Always hold the stationary nut on the gas line coupling with one wrench while turning
the moveable coupling nut with the other wrench.
3. Remove the compressor’s top panel and the side panel nearest the gas supply coupling.
NOTE
Trace the outline of the adsorber base on the compressor base to help locate the
proper position for the new adsorber.
4. Disconnect the self-sealing coupling on the inlet side of the adsorber. Use two wrenches.
5. Elevate the compressor to gain access underneath the bottom panel. Remove the M10
hex-head bolt and lock washer holding the adsorber to the base. Use a 17-mm wrench.
AVOID EQUIPMENT FAILURE, CONTAMINATION OR A NUISANCE
SHUTDOWN
. Do not tip the compressor greater than 5 degrees from horizontal
to avoid flowing oil into unwanted places and causing a nuisance shutdown.
6. Remove the lock nut on the supply coupling on the front panel.
7. Pull the adsorber back until the supply coupling clears the front panel. Remove the
adsorber. Remove the lock washer from the Aeroquip supply coupling. Retain all hardware
to use with the new adsorber.
AVOID INJURY. The adsorber is charged with helium gas. Follow the adsorber
venting procedure for safe disposal of the used adsorber.
Adsorber Installation
1. Remove the caps from the gas lines of the new adsorber. Do not vent the new adsorber.
2. Insert the supply coupling through the front panel and position the adsorber on the base
within the traced outline. Be sure the lock washer is installed on the coupling prior to
inserting it through the front panel.
3. Apply Loctite 242 to the threads of the bolt used to secure the adsorber to the base. Install
and tighten this bolt and lock washer. Lower the elevated compressor to the floor.
4. Install the nylon washer and the locknut on the supply coupling. Torque the locknut to
5.5 kgf m (40 ft. lbs.).
5. Connect the adsorber’s self-sealing coupling on its inlet side to the oil separator’s outlet
coupling. With wrenches, torque the Aeroquip coupling to 4.85 ± 0.7 kgf m (35 ± 5 ft. lbs.).
