110-511 PSC/EN 18
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.
Enter a temperature set point of approximately 50°C and then allow the bath to stabilize at that
1.
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.

Attainable Temperatures:
Your MX Immersion Circulator can be used with reservoirs of various capacities and shapes as well as
different fluids. These variables may adversely affect temperature accuracy and stability. For example, a
reservoir with a large surface area loses heat more quickly, which may prevent the Circulator from
attaining the desired temperature.
110-511 PSC/EN 21
Reservoir Fluids
Depending on your needs, a variety of fluids can be used with your Immersion Circulator. No matter what
bath fluid is selected, it must be chemically compatible with the reservoir and the materials in your
Immersion Circulator. It must also be suitable for the desired temperature range.
WARNING: Do not use a flammable liquid as a bath fluid as a fire hazard may result.
WARNING: Always use fluids that satisfy safety, health, and equipment compatibility requirements.
For optimum temperature stability, the fluid’s viscosity should be 50 centistokes (cSt) or less at its lowest
operating temperature. This permits good fluid circulation and minimizes heating from the pump.
For temperatures from 10°C to 90°C, distilled water is recommended. For temperatures below 10°C, a
mixture of laboratory grade ethylene glycol and water should be used. Do not use deionized water.
The following chart is intended to serve as a guide in selecting a bath fluid for your application. For
optimum temperature stability and low vaporization, be sure to stay within the fluid's normal temperature
range.
You are responsible for proper selection and use of the fluids. Avoid extreme range operation.

WARNING: DO NOT USE THE FOLLOWING LIQUIDS:
• Automotive antifreeze with additives**
• Hard tap water**
• Deionized water with a specific resistance > 1 meg ohm
• Any flammable fluids
• Concentrations of acids or bases
• Solutions with halides: chlorides, fluorides, bromides, iodides or sulfur
• Bleach (Sodium Hypochlorite)
• Solutions with chromates or chromium salts
• Glycerine
• Syltherm fluids
At temperatures above 40°C, additives or mineral deposits can adhere to the heater. If deposits are allowed
**
to build up, the heater may overheat and fail. Higher temperatures and higher concentrations of additives
will hasten deposit build up.
Application Notes
At a fluid's low temperature extreme:
• The presence of ice or slush adversely affects temperature stability.
• A viscosity above 10 centistokes adversely affects temperature uniformity.
• A high fluid viscosity and high pump speed adds heat to the fluid being pumped.
At a fluid's temperature above ambient without refrigeration:
• If your set point temperature is less than 15°C above the ambient temperature, the
viscosity of the fluid should be 10 centistokes or less to minimize friction heating of the fluid.
• Heat loss should be encouraged by uncovering the fluid and lowering the pump speed.
At fluid's high temperature extreme:
• Heat loss from vapor adversely affects temperature stability.
• To prevent the accumulation of vapors inside the room, the reservoir may need to be
placed in a fume hood.
• Use a cover and/or floating hollow balls to help prevent heat and vapor loss.
• Replenish fluid lost from vapor frequently.

Warranty
The manufacturer agrees to correct for the original user of the product, either by repair (using new or
refurbished parts), or at the manufacturer’s election, by replacement (with a new or refurbished product),
any defects in material or workmanship which develop during the warranty period. The standard warranty
is twenty-four (24) months after delivery of the product. In the event of replacement, the replacement unit
will be warranted for the remainder of the original warranty period or ninety (90) days, whichever is
longer. For purposes of this limited warranty, “refurbished” means a product or part that has been
returned to its original specifications. In the event of a defect, these are your exclusive remedies.
If the product should require service, contact the manufacturer’s/supplier’s office for instructions. When
return of the product is necessary, a return authorization number is assigned and the product should be
shipped, transportation charges pre-paid, in either its original packaging or packaging affording an equal
degree of protection to the indicated service center. To insure prompt handling, the return authorization
number must be placed on the outside of the package. A detailed explanation of the defect should be
enclosed with the item.
The warranty shall not apply if the defect or malfunction was caused by accident, neglect, unreasonable
use, improper service, acts of God, modification by any party other than PolyScience, or other causes not
arising out of defects in material or workmanship.
EXCLUSION OF IMPLIED WARRANTIES. THERE ARE NO WARRANTIES, EXPRESSED OR
IMPLIED, INCLUDING, BUT NOT LIMITED TO, THOSE OF MERCHANTABILITY OR FITNESS FOR A
