
When using compounds in the CentriVap Cold Trap that are hostile to the
materials of construction, it is imperative that the equipment is appropriately
maintained. After each run, clean up all residues, spills and materials that
might have splashed in the chamber.

Drain the Cold Trap immediately after the collected ice is melted to prevent
corrosive liquids from residing in the trap. Flush out the trap with water after
draining.
DO NOT chip ice off the Cold Trap walls as damage may occur.
DO NOT start a rotary vane pump when the Cold Trap contains any liquid or
if there is any liquid in the vacuum tubing. The liquid will be drawn into the
pump and will contaminate the vacuum pump oil.

If the stainless steel cold trap chamber is attacked by the compounds in use
consider using the optional Glass Trap insert. See Chapter 5: Accessories for
Your CentriVap.

When using a rotary vane vacuum pump the oil in the pump should be
checked often. It must be changed if it is cloudy, shows particles or is
discolored. The useful life of vacuum pump oil can be extended if the
vacuum pump is operated for an extended period of time with the gas ballast
open after the run is over. This allows contaminants to be purged from the
hot oil. This must be done with the inlet to the pump blocked off to prevent
air from free flowing through the pump. If the pump is operated at an
elevated vacuum level, oil will be expelled from the pump and damage will
occur.

If optional secondary traps are used, monitor their condition often and
replace them when they are saturated. A new acid trap is off-white and
changes color to purple when used up. A new moisture trap is blue and
changes color to pink when used up. The solvent trap molecular sieve does
not change color when saturated so extra care must be taken to determine
when a replacement cartridge should be installed.
Solvent Safety Precautions
CAUTION: Solvents used in the CentriVap Cold Trap may be flammable or
hazardous. Use extreme caution and keep sources of ignition away from the
solvents. When using flammable or hazardous solvents, both the CentriVap
Cold Trap and the vacuum pump should be operated inside a fume hood.
Hazardous materials, such as strong acids or bases, radioactive substances
and volatile organics, must be handled carefully and promptly cleaned up if
spilled.
