Installation
AVOID GAS LEAKS. Check the condition of the gasket seal on the male half of
each Aeroquip coupling. Be sure the gasket seal is in place and the sealing
surfaces on both the male and female halves are clean before connecting.
Replace the gasket seal if it is damaged or missing. Keep the gas line couplings
aligned when making or breaking a coupling connection. Leaks can occur due to
the weight of the gas line or due to a sharp bend near the connection
Retain the threaded dust caps and plugs to re-cover the couplings when they are
not in use. They protect the couplings from damage and prevent entry of
contaminants.
5. Connect the supply gas line to the supply coupling on the compressor or to the supply gas
manifold. Use two wrenches to tighten the coupling. See Figure 10.
Torque all couplings to 4.85 ± 0.7 kgf m (35 ± 5 ft. lbs.)
Tighten each coupling before proceeding to the next one.

6. Connect the return gas line to the return coupling on the compressor or to the return gas
manifold.
7. Remove the dust caps from the helium supply and return couplings on the cryopump.
Screw the dust plugs from the gas lines into the dust caps from the cryopump and store
them.
8. Connect the return gas line to the return coupling on the cryopump. Torque the coupling to
4.85 ± 0.7 kgf m (35 ± 5 ft. lbs.). See Figure 10.
9. Connect the supply gas line to the supply coupling on the cryopump. Tighten the coupling
as described in Step 8.
10. Leak check all the Aeroquip coupling connections.
