CryoProbe Safety

Equipment Safety

CAUTION:

• Do not bend the CryoProbe.

Do not hold the CryoProbe at its upper tube, always carry it at its body.

• Do not open the CryoProbe.

There are no user-serviceable parts inside. A CryoProbe cannot be sealed or
reassembled without special equipment. Even undoing some screws can destroy factory
settings and will in general render the CryoProbe unusable.

• Never force a CryoCoupler into position.

• Do not obstruct the operation of the safety-valves on the top and front faces of the

CryoProbe body.

• Never force a CryoCoupler into position.

• Do not move a cryogenically cold device.

• Do not try to fix a leak on a cold part because cracking of frozen O-rings, valves etc. may

occur.

• Excessive RF power can destroy the CryoProbe or the HPPR. Obey the limitations given

on the specific ‘LIMITATIONS - WARNINGS’ sheet.
