Installation and Startup Your Circulating Bath with MX Temperature Controller is designed to be simple to set-up and install. The only tools required are a flat-head screwdriver and a container for adding water or another suitable fluid to the bath reservoir. General Site Requirements Locate your Circulator on a level surface free from drafts and direct sunlight.
External Closed Loop Circulation WARNING: When connecting tubing to an external application, it is the user’s responsibility to make sure that the tubing and fittings connected to the Circulator are suitable for the fluid being used and the temperature range of operation. CAUTION: The Circulator’s bypass tubing is secured to the fluid inlet and outlet connections by high temperature nylon hose clamps, which can be removed by carefully cutting them with diagonal cutters.
Refrigeration Control Connections (Refrigerating/Heating Circulators only) Attach the Refrigeration Control Cable connected to the rear of the Temperature Controller to the Refrigeration Control Connection on the Refrigeration Power Module.

Electrical Power WARNING: The Circulator’s power cord must be connected to a properly grounded electrical receptacle. Make certain that this electrical outlet is the same voltage and frequency as your Circulator. The correct voltage and frequency for your Circulator are indicated on the identification label on the back of the Controller.
Controller Setup Power Press ; all characters and symbols on the LCD will momentarily light. The Circulator will begin running, actual and set point temperatures will be displayed, and the word “SET” will be continuously lit. The circulating symbol will also be lit and the heating or refrigerating symbol may be lit or flashing. Heating Refrigerating Circulatingl...
Normal Operation Keys and Controls Power Turns the Circulator’s Temperature Controller ON. Accesses the Temperature Controller’s set-up sub-menus. The items in these sub-menus are used to configure the Controller’s general Menu operational parameters (temperature unit, upper and lower temperature limits, offset calibration, etc.). Used to increase temperature set point and other operational Up Arrow settings/values.
Set-Up Sub-Menus Press the key to access the Temperature Controller’s set-up sub-menus. The keys are used to change the current setting / value in the sub-menu. To Change Sub-Menu Selection / Range Current Value Press for °C Temperature unit °C or °F Press for °F Offset Calibration...
Selecting the Temperature Unit The temperature units sub-menu (°C / °F) allows you to select the temperature unit in which the actual bath temperature and set point temperature are displayed. The factory default is °C. Appears when in Temperature Units sub-menu To Access: Press the key until °...
Setting the Offset Calibration This sub-menu allows you to match the Circulator’s temperature display to an external reference thermometer. A value from -3.0° to +3.0°C may be entered; the factory default is 0.0°C. IMPORTANT: To prevent the Offset Calibration value from being changed unintentionally, the following power down/power up sequence is required to enable the Offset Calibration function.
Setting the Low Limit Temperature This sub-menu allows you to limit how low the temperature set point may be set. It also serves as a low limit safety, alerting you if bath temperature falls below the low limit temperature setting. The Low Limit value may be set from -35°...
Setting the High Limit Temperature This sub-menu allows you to limit how high the temperature set point may be set. It also serves as a high limit safety, alerting you if bath temperature rises above the high limit temperature setting. The High Limit value may be set from +40°...
Adjusting the Auto Cool Temperature This sub-menu is displayed only on Refrigerating / Heating Circulators. It determines the bath temperature at which refrigeration will be activated and permits more precise control when operating at high temperatures as well as more rapid cool downs. For most applications, an Auto Cool set point 15°C above room temperature is recommended.
Resetting the Factory Default Values You can return your Circulator to all factory-set defaults as follows: 1. Press the key to turn the Circulator OFF. 2. Turn Mains power OFF by unplugging the power cord from the electrical outlet or (Refrigerating/Heating Circulators) placing the power switch/circuit breaker on the Refrigeration Power Module in the OFF position.
Tap Water Cooling Tap water cooling allows for more rapid bath cool down from high temperatures and/or more precise operation at temperatures near ambient. Heat only Circulating Baths feature an integrated cooling coil as standard equipment. The tap water connections are made on the rear of the unit. Two 0.25 inch / 6.4 mm female NPT fittings are provided for these connections.

Warning: The temperature set Decrease the Low Limit temperature value or increase the point is below the Low Limit temperature set point.
Routine Maintenance and Troubleshooting WARNING: Always turn your Circulating Bath OFF and disconnect it from the electrical power outlet before performing any maintenance or service. WARNING: To avoid the potential for burns, allow the Circulating Bath to cool completely before cleaning or performing any maintenance.
Polycarbonate Open Tank Circulators Larger capacity (17 liter and above) polycarbonate open tank Circulating Baths are equipped with a drain port. To drain fluid from these baths, remove the knurled cap. When replacing the cap, do not over tighten. WARNING: Be sure to replace and tighten knurled cap before refilling the bath reservoir. Checking the Over-Temperature Safety System Your Circulator incorporates over-temperature protection according to IEC 61010.
Cleaning Your Circulator WARNING: It is the user’s responsibility to properly decontaminate the unit in the event hazardous materials are spilled on exterior or interior surfaces. Consult the manufacturer if there is any doubt regarding the compatibility of decontamination or cleaning agents. Temperature Controller Turn the Temperature Controller OFF by pressing and unplug power cord from the electrical outlet.
Temperature Controller Removal and Re-Installation Removal The Temperature Controller on your Circulating Bath is designed to be easily removed from the top deck without the use of special tools. It is removed as follows: 1. Place the tip of a small flat blade screwdriver under the retaining ring locking tab and pry up gently.
Page 33
Re-Installation The top deck of your Circulator incorporates four alignment pins to facilitate positioning of the Temperature Controller when it is being reinstalled. These pins correspond to keyhole slots on the interior of the Circulator’s retaining ring. 1. With the retaining ring locking tab oriented above one of the indents on the top deck, slowly lower the Temperature Controller into the top deck opening until it is resting on top of the positioning pins.
