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

draining.

agents.

WARNING:

• Allow the bath fluid to return to ambient

temperature before draining.

• Keep within the 85°C maximum operating

temperature limit if using a polycarbonate bath.
