2.2 General Description
Refrigerating/Heating and Heat Only Circulating Baths with the Standard Controller are designed for
use as stand-alone baths or to provide precise temperature control of fluids for closed loop
circulation to external equipment.
All Circulating Bath models feature a reservoir which may be used for immersing samples while the
unit is connected to an external device. Circulating bath models are equipped with either 6, 13, or 28
liter reservoirs. All wetted parts are corrosion resistant 300 series stainless steel.
Refrigeration is normally required for operation at temperatures below 40°C. However, refrigeration
should not be used when the fluid temperature is above 55°C. Refrigeration should not be turned on
when the ambient air temperature is above 32°C.

Warning : These units are equipped with over-temperature protection (Safety Set). A low-liquid
level or failure to set the Safety Set and properly immerse the heater may result in heater burnout
and triac failure. While operating, do not allow the heater to contact any potentially flammable
materials, such as plastic trays or the sides of plastic tanks, as a fire hazard may result.
