Chapter 4: Maintaining Your CentriVap Cold Trap
Product Service 1-800-522-7658
NOTE: IF THE ICE HAS MELTED, THE GLASS TRAP INSERT MUST
BE EMPTIED BEFORE THE COLD TRAP IS STARTED AGAIN.
7. If the Glass Trap is used, check to see that the ethanol in the stainless steel
trap is free of ice or water. Drain the ethanol and replace it with fresh ethanol.
8. If the media in the cartridge in the optional clear canister has changed color,
discard and replace the insert with a new insert. For the radiochemical trap
insert, no indicator exists; therefore, it should be discarded after each use. In
radioactive applications, the system should be monitored with a Geiger
counter.
9. Check the continuity of the protective earth between the ground terminal on
the power inlet and a bare metal housing panel. Contact Labconco if there is
no continuity.
10. Repair any defects to the surface where the CentriVap Cold Trap is installed.
Monthly:
1. The rubber components on the CentriVap Cold Trap may eventually
deteriorate and require replacement. The effective life of rubber parts depends
upon both their usage and the surrounding environment. Check all rubber
hoses and gaskets and replace any that show signs of hardening, permanent set
or deterioration.
2. Using a soft cloth, sponge, or chamois and a mild, non-abrasive soap or
detergent, clean the exterior surfaces of the unit. Liquid spray cleaners and
polishes may be used on the exterior surfaces. Do not use solvents to remove
stains from the exterior surfaces as they may damage the finish.
Annually:
1. Every 12 months, or more often, if the Cold Trap is operated in a dusty
environment, the refrigeration system condenser of the Cold Trap should be
cleaned. Using a vacuum cleaner with brush attachment, clean the condenser
to ensure proper airflow for peak performance. Disconnect power to the Cold
Trap prior to removing covers.
