
Do not use overfilled cylinder; gas pressure may be excessive and
present a hazard. (9 kilo cylinders should not contain over 9 kilos of
liquid Carbon Dioxide CO
USED IF CYLINDER PRESSURE IS GREATER THAN 800 PSI
(56.25 kg/cm

Move cylinder to a well ventilated area when venting. Carbon Dioxide
in excessive concentration may be hazardous to health. A scavenging
hose is available to divert gas escaping from the Gas Exhaust Port,
away from the operator and patient.

Periodic visual inspection of cryo instrument and tips is essential. Discontinue use of any product
suspected of being damaged. Such product should be returned to Wallach for inspection and service.

At no time should chlorine mixtures (bleach) or iodine-based products be used for soaking or
cleaning Wallach cryotips. Cryotips will degrade if exposed to such solutions.

Moisture in lines and orifices of the cryotip can cause sputtering, poor freeze and other
malfunctions. (Whenever using fluids or steam to clean or sterilize, all gas lines and cryotip orifices
must be plugged or corrosion may result). Plugs are available from Wallach for the cryotips.

Overexposure of tissue may cause cryogenic burns (similar to severe frostbite) as a result
of the rapid evaporation of the liquefied gas.

CHANGING CRYOTIPS MUST BE DONE WITH THE ON/OFF VALVE "OFF".
If ON/OFF valve is "ON" while changing tips, injury may occur due to tip separation from
cryosurgical freezer at high pressure.
