Section 2. Set Up
2.1 Location
Locate your circulator on a level surface free from drafts and direct sunlight. Do not place it near corrosive
fumes, excessive moisture, high room temperatures, or excessively dusty areas. Refrigerated circulators
must be four inches minimum away from walls or vertical surfaces so air flow is not restricted. Avoid voltage
drops by using properly grounded power outlets wired with 14 gauge or larger diameter wire and close to
the power distribution panel. To avoid low line voltage problems, do not use an extension cord.
2.2 Filling the Reservoir
Maximum fill level is one inch below the top of the reservoir. When in operation, add additional fluid to
compensate for any additional volume needed for external circulation.
Minimum liquid depth is enough to fully cover the heater, pump, and one inch of the temperature sensor. If
the proper fluid level is not maintained the heater coil may become exposed and possible damage to the
heater may result.
Warning: These units are equipped with Over Temperature Protection (OTP). Failure due to low
liquid level or failure to set OTP 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 racks, as a fire hazard may result.
2.3 Reservoir Fluids
Use distilled water for temperatures from 10° to 90°C or a mixture of laboratory grade ethylene glycol and
water for temperatures -20° to 100°C. A variety of fluids can be used depending upon your needs. The fluid
must be chemically compatible with the reservoir and with 300 series stainless steel in the pump and heater.
The fluid must also be able to produce the temperature range desired.
For temperature stability of ±0.01°C, the viscosity should be 50 centistokes or less at the lowest operating
temperature to allow good fluid circulation and to minimize heating from the pump. Most single type of fluids
will be able to stabilize to ±0.01°C over a 100°C range. Use fluids that will satisfy safety, health, and
equipment compatibility requirements.
The following chart will help in selecting a fluid for your application. Stay within the fluid’s normal range for
best temperature stability, low vaporization, and safety.
