The user is always responsible for the fluid used. Never use corrosive
fluids with this circulator.
Never use 100% glycol.
Handle and dispose of liquids, other than water, in accordance with
the fluid manufacturers specification and/or the SDS.
Adjust the circulator's software to the fluid used, see Section 4.
When using water above 80°C closely monitor the fluid level, frequent
top-offs will be required. It also creates steam.
Water/glycol mixtures require top-offs with pure water, otherwise the
percentage of glycol will increase resulting in high viscosity and poor
performance.

Circulators are used with water only. 
The fluid information is only a guide since specifications may change.
Thermo Fisher Scientific takes no responsibility for damages caused by the
selection of an unapproved bath fluid.
Unapproved bath fluids are fluids which:
• are very highly viscous (much higher than 30 mPas at the respective
working temperature)
• have corrosive characteristics or
• tend to break down at high temperatures
For fluid selection consider application requirements, operating temperature
range, material compatibility, safety concerns, and environmental issues.
Chlorine
Short term usage of tap water may not cause any adverse affects on the
circulator or your application, but in the long term problems may arise. To
help alleviate these problems Thermo Fisher Scientific recommends the use
of chlorine.
The duration of time that chlorine remains in solution depends on factors
such as water temperature, pH and availability of direct sunlight. We
recommend maintaining chlorine levels at proper levels using chlorine test
strips, generally 1 to 5 ppm is adequate.
