Section 1 - General Information Warranty Thank you for purchasing this circulator. We are confident it will serve you for a long time. Our warranty to you is as follows: The manufacturer agrees to correct for the original user of this product, either by repair, or at the manufacturer's election, by replacement, any defect that develops after delivery of this product within the period as stated on the warranty card.
Circulator Pump The two-speed simplex (pressure) pump may be used for tempering of samples in the reservoir or for circulation in closed loops. It is not designed for pumping from the circulator's reservoir into and out of a second open reservoir. The HIGH or LOW Speed Selection Switch on the rear of the Controller is used to select pump speed.
Filling the Reservoir The maximum fill level for the Circulating bath is one inch Temperature (25mm) below the top of the reservoir. A liquid level that fully Sensor covers the heater coil, pump, over-temperature sensor, and at least one inch (25mm) of the temperature sensor must be Minimum maintained.
Set-Up The Immersion Circulator may be clamped directly to the side of a reservoir (user supplied) or to a support rod adjacent to the reservoir. To produce the best fluid circulation, the rotating pump outlet nozzle should be pointed along one side of the reservoir wall.

Reservoir Liquid Level Fill the reservoir with the appropriate bath fluid. On Circulating Baths, the liquid level should be sufficient to cover the heating coils, pump, over-temperature sensor, and at least one inch (25mm) of the temperature sensor. On Immersion Circulators, the liquid level should be sufficient to fully immerse the heater coils, over-temperature sensor, and pump outlet nozzle.
To change from ° F to ° C, place the Circuit Breaker/Power Switch in the OFF position and then press and hold the P3 Button while turning the power back ON. NOTE: When the temperature display units are changed, the Software High Limit value and all temperature presets revert to the factory-default values.
Local Lockout Feature This feature enables the user to lock all controls on the controller. While the feature is activated, the unit will remain running at the current settings. To activate the local lockout feature, press and hold the Select/Set Knob for 10 seconds. Once locked, the screen will read LLo.

Pump Motor The pump bearings are permanently lubricated with high-temperature silicone grease and do not require additional lubrication. Should the bearings become noisy, replacement of the entire pump motor is recommended. This will reduce repair labor costs and retain fluid pumping reliability. A replacement pump and motor mounting kit is available (see Section 10 - Replacement Parts).
No Heating • Verify that the unit is pumping properly. • If the heat light is not lit, check the control temperature set point and bath temperature to verify that heating is required. • Verify that the liquid in the bath covers the heater coils. •...
Section 8 - Reservoir Fluids Depending on your needs, a variety of fluids can be used with your Circulator. No matter what bath medium is selected, it must be chemically compatible with the reservoir and with the 300 series stainless steel in the pump and heater. It must also be suitable for the desired temperature range. Always use fluids that satisfy safety, health, and equipment compatibility requirements For optimum temperature stability, the fluid’s viscosity should be 50 centistokes or less at its lowest operating temperature.
Application Notes At a fluid's low temperature extreme: 1. The presence of ice or slush adversely affects temperature stability. 2. A viscosity above 10 centistokes adversely affects temperature uniformity. 3. A high fluid viscosity and high pump speed adds heat to the fluid being pumped. At a fluid's temperature above ambient without refrigeration: 1.
