Installing a Glass Lid
Turn off the CentriVap. Unplug the power cord from the wall receptacle. Pull
outward on the hinge pin knob. Lift and remove the old lid. To install the new
lid, reverse the process.
Installing a Secondary Chemical Trap
An accessory secondary chemical trap is available to minimize the exhausting of
solvents into the atmosphere. It may be attached to either side of the Cold Trap.
After selecting the side, remove the two small plastic hole plugs. Attach the
bracket to the side of the Cold Trap housing using the screws provided. Attach
the hose from the Cold Trap Lid Assembly to the “out” connector of the canister
housing. Connect another hose from the remaining fitting on the Secondary Trap
to the inlet port on the vacuum pump. Clamp hoses securely. Unscrew the clear
bowl of the canister housing from the head. Remove both the upper and lower
caps from the filter cartridge and insert the small end of the cartridge into the hole
in the center of the head. Reinstall the clear bowl.
Be sure to use the proper cartridge for your application. The moisture cartridge is
used to trap water vapor. The acid cartridge is used to trap acid vapors. The
solvent cartridge is used to trap solvent vapors and the radiochemical cartridge is
used to trap radioactive waste.
When the media in the insert has changed color, discard the insert and replace it
with a new insert. For the radiochemical trap insert, no color indicator exists
therefore it should be discarded after each use. Use a Geiger counter to monitor
the pump exhaust.
NOTE: This radiochemical cartridge does not meet NRC filter design
recommendations. After operating, properly dispose of all hazardous
materials in compliance with all applicable codes. Labconco is not
responsible for improper disposal of any materials.
