•
Locate the helium compressor package within 10 ft (3 m) of the dewar. If greater
separation is required, longer helium flex lines, as well as a longer dewar cord, will be
needed.
•
Position the helium compressor package so there is sufficient space around it for
changing the adsorber. If the helium compressor package cannot be moved easily to
an open area, leave approximately 2 additional feet (0.6m) clearance above and to
the left and right of it. Allow for 2 feet (0.6m) of clearance around all four sides and 3
feet (1m) of clearance above air-cooled models for proper air flow.
6.3.2 Connect the water lines to the helium compressor (water-cooled
models only)
CAUTION
Cooling water must meet the requirements in Section 5. If water that does not meet
the cooling water specifications in Section 5 is introduced into the system, even for
cleaning purposes, it will void the warranty.
CAUTION
Do not apply heat to the cooling water inlet and outlet connectors located on the front
panel of the compressor.
1) Make sure that the cooling water supply is turned OFF.
2) Apply Teflon tape or pipe sealant to the threads on the male pipe thread (MPT)
fittings that you provide to connect to the compressor’s cooling water inlet connection
and the cooling water outlet connection.
o
CP900 and CP800 Series Compressors require 1/4 MPT (1/4” Male National
Pipe Thread) fittings.
o
CP2800 and CP1000 Series Compressors require 3/8 MPT (3/8” Male National
Pipe Thread) fittings.
3) Attach the fittings to the compressor’s cooling water inlet and outlet connections.
Turning the fitting clockwise, first hand-tighten the connection. Use a wrench to keep
the compressor’s cooling water connections from turning, and use another wrench to
tighten fittings until snug.
4) Attach the supply water line to the Cooling Water IN fitting and the return water line to
the Cooling Water OUT fitting.
5) Turn the cooling water supply ON and check for leaks.
6) Make certain the cooling water flow rate and inlet temperature meets the
requirements in Section 5.
