AVOID EQUIPMENT FAILURE OR CONTAMINATION. Use SHIG adsorber P/N F300138A
only. Use of non-SHIG spare parts will void the warranty.
The compressor’s adsorber should be replaced every 30,000 operating hours (40 months).
The used adsorber has no salvage or repair value. Venting the compressor is not required
when replacing the adsorber because the gas couplings are self-sealing.
Adsorber Removal
1. Stop the compressor and disconnect the power to the compressor.
2. Disconnect the high pressure (supply) gas line from the helium high pressure coupling on
the compressor. Screw a dust plug into the disconnected gas line. Use two wrenches.
NOTE
Always hold the stationary nut on the gas line coupling with one wrench while
turning the moveable coupling with the other wrench.
3. Remove the compressor’s cover panel.
4. Disconnect the self-sealing coupling on the inlet side of the adsorber. Use two wrenches.
Hold jam nut with one wrench
Turn water line coupling with
the other wrench
