Bath Reservoir and Wetted Components
A concentrated bath cleaner (polyclean Bath Cleaner, part number 004-300050) is available to remove
mineral deposits from the Temperature Controller’s wetted parts. The cleaner should be added to the
bath reservoir at the prescribed dosage and circulated at 60°C / 140°F until the scale is removed.
Pump Impeller
In the unlikely event that debris becomes lodged in the pump impeller, a soft brush can be used to
remove any lodged particles. If necessary, soak in a solution of distilled water and polyclean Bath Cleaner
to soften before brushing.
CAUTION:
Do not use hard utensils or abrasive pads to remove trapped debris.
Checking the Over-Temperature Safety System
Your Circulator incorporates over-temperature protection according to IEC 61010. For optimum safety,
this system should be checked for proper operation at least every six months. This check must be
performed with the unit running.
1. Enter a temperature set point of approximately 50°C and then allow the bath to stabilize at that
temperature. The amount of time this will take will depend on the size of the bath and the difference
between the initial bath temperature and the Safety Set temperature.
2. Once the bath temperature has stabilized, slowly rotate the Safety Thermostat
counter-clockwise until you hear a soft “click;” the OVERTEMP or LOW FLUID
alarm symbol will appear on the display approximately 5-10 seconds later. At
this point, the heater will also turn OFF.
3. Slowly rotate the Safety Thermostat clockwise until the alarm symbol
extinguishes (you may also hear a soft “click”). The heater should turn back
ON.
4. Reset the Safety Set temperature to the desired temperature value
(see
Installation and Startup
).
