Safety Recommendations
To prevent injury to personnel and/or damage to property,
follow your workplace’s safety procedures when operating
this equipment. You should comply with the following safety
recommendations:
WARNING:
• This Immersion Circulator is suitable only for use
with Class I non-flammable fluids
(per DIN 12876-1).
• Be aware of the chemical hazards that may be
associated with the bath fluid used. Observe all
safety warnings for the fluids used as well as those
contained in the material safety data sheet.
• Use only recommended bath fluids.
• Use only non-acid bath fluids.
• Use fluids that satisfy safety, health and equipment
compatibility requirements.
!
WARNING:
• Connect the power cord on this unit to a properly
grounded power outlet. Make certain that the outlet
is the same voltage and frequency as your unit.
• Never operate the unit with a damaged power cord.
• The use of an extension cord is not recommended.
• Turn the unit OFF and disconnect mains power
before performing any maintenance or service.
WARNING:
• Never operate the Circulator without bath fluid in
the reservoir. Periodically check the reservoir to
ensure that the liquid depth is within acceptable
levels. Refill the reservoir using the same bath
fluid that is already in the reservoir. Bath oil must
not contain any water contaminants and should be
preheated to the actual bath temperature before
adding as there is an explosion hazard at high
temperatures.
• Drain all fluid from the reservoir before moving
or lifting. Be sure to follow your organization’s
procedures and practices regarding the safe lifting
and relocation of heavy objects.
• Turn electrical power to the unit OFF and remove
the Immersion Circulator from reservoir before
