To reuse CryoCool that has a layer of water, transfer it to a container and
allow to settle again into a bilayer. Place in a freezer until the water layer
freezes. The liquid fraction is CryoCool, which can be reused. Decant off
the CryoCool and dispose of the ice.
Refrigerated Vapor Traps reach low operating
CAUTION!
temperatures that can cause severe damage to unprotected skin.
Wear protective gloves and clothing when removing CryoCool, ice,
and glass vessels from the trap.
If the vapor trap vibrates excessively, have the line voltage checked with a
voltmeter. The voltage must be above 108V for 120V units and above 209V
for 240V units.
Low line voltage may cause thermal overload of the unit.
CAUTION!
Vapor traps require proper air flow for ventilation. At least every three
months, clean the condenser grill. Dust and dirt on the grill can block air
flow. Be sure to turn the trap off before cleaning so that dust and dirt are
not drawn into the trap. Use a vacuum cleaner with a brush attachment, or
purge the condenser with compressed air.
The refrigeration system in the trap is hermetically sealed and does not
require maintenance.
