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 rotors for loose or missing parts. Tighten or replace as required. Do
not use defective rotors.
10. Inspect the chamber to insure that there are no cracks or structural damage.
Call Labconco if defects exist.
11. Check 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.
12. Repair any defects to the surface where the CentriVap is installed.
Monthly:
1. The rubber components on the CentriVap may eventually deteriorate and
require replacement. The effective life of rubber parts depends upon both
their usage and the surrounding environment. Check all 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 glass lid.
3. 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 Refrigerated CentriVap or Cold Trap is
operated in a dusty environment, the refrigeration system condenser should be
cleaned. Using a vacuum cleaner with brush attachment, clean the condenser
to ensure proper airflow for peak performance. Disconnect power before
removing covers.
