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. Do not place it where there
are corrosive fumes, excessive moisture, high room temperatures, or in excessively dusty areas.
Refrigerating / Heating Circulators must be 10.2 cm / 4 inches or more away from walls or vertical
surfaces so that airflow is not restricted.
Avoid voltage drops by using properly grounded power outlets wired with 14 gauge or larger diameter
wire and if possible, be close to the power distribution panel. The use of extension co rds is not
recommended; this will reduce the potential for problems caused by low line voltage.
Adding Liquid to the Bath Reservoir
WARNING: Read the safety data sheet for the bath fluid being used carefully before filling reservoir.
WARNING: See Technical Information in the rear of this manual for a list of compatible liquids.
WARNING: If the proper fluid level is not maintained, the heater coil may become exposed and
possibly damaged (fluid level too low) or the bath may overflow (fluid level too high).
The liquid in the reservoir should be maintained at a depth between 1 inch / 2.54 cm and 2.6 inches / 6.7
cm below the underside of the bath’s top deck. Upon start up, it may be necessary to add fluid to the bath
to compensate for the fluid required for external circulation. Likewise, be sure to comp ensate for fluid
displacement when placing samples or other materials in the Circulator’s reservoir.
Maximum Liquid Level:
1 in. / 2.54 cm
below the underside of the top deck
Minimum Liquid Level:
2.6 in. / 6.7 cm below the
underside of the top deck
WARNING: Always drain all fluid from the reservoir before moving or lifting your Circulator. Be sure
to follow your organization’s procedures and practices regarding the safe lifting and relocation of
heavy objects.
WARNING: To avoid the potential for burns, allow the Circulator to cool completely before cleaning
or performing any maintenance.
110-509 PSC/EN 13
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.
CAUTION: Secure the tubing to the inlet and outlet fittings using hose clamps with a minimum ID of
7/8 inch (22 mm). Do not operate the unit without hose clamps.
WARNING: If the Circulating Bath will not be used for external circulation, the inlet and outlet ports
should remain connected using the Buna N bypass tubing provided with the unit.
The single speed pump on your Circulating Bath permits closed loop circulation to an external apparatus
via the ½ inch / 12.7 mm OD pump inlet and outlet ports on the rear of the MX Controller. To maintain
adequate flow, avoid restrictions in the tubing.
The control stability of a closed loop system is better at the external apparatus than in the immediate
vicinity of the heater (provided the apparatus control point represents a constant load and is well
insulated). For example, if you circulate through a viscometer at 50°C the temperature variation observed
in the reservoir may be ±0.1°C, whereas in the viscometer it may be only ±0.05°C.
Although stability is better at the external apparatus control point, depending on the insulation and length
of tubing used, the accuracy of temperature may be slightly different than the temperature indicated in the
reservoir.
NOTE: Viscosity Baths and the Coliform Bath are not equipped for external circulation.

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.
CAUTION: The use of an extension cord is not recommended. If one is necessary, it must be
properly grounded and capable of handling the total wattage of the unit. The extension cord must not
cause more than a 10% drop in voltage to the unit.

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.
WARNING: Always drain all fluid from the reservoir before moving or lifting your Circulator. Be sure
to follow your organization’s procedures and practices regarding the safe lifting and relocation of
heavy objects.
Maintaining Clear Bath Water
Optimum temperature and moisture conditions for algae growth exist when using water as a bath fluid. To
prevent algae contamination and minimize the frequency of draining the reservoir, an algaecid e such as
polyclean Algaecide (004-300040) should be used.
WARNING: Do not use chlorine bleach.
Draining the Bath Reservoir
WARNING: Bath fluids should be stored and disposed of according to applicable laws and
regulations.
Refrigerated / Heating and Heat only Circulating Baths
Refrigerated / Heating and Heat only Circulating Baths are equipped with a drain valve and port located
either behind the front access panel or on the right hand side of the unit.
To drain fluid from the bath, attach a short length of suitable 11.5 mm ID / 0.45 inch ID tubing to the drain
port and secure it using a hose clamp with a minimum ID of 18 mm / 0.7 inch. Open the drain valve using
a flat blade screwdriver. When closing the valve, do not over tighten.
Drain Port Drain Valve
WARNING: Be sure to close the drain valve before refilling the bath reservoir. Do not over tighten.
110-509 PSC/EN 28
Polycarbonate Open Tank Circulators
Larger capacity (17 liter and above) polycarbonate open tank Circulating Baths are equi pped 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. 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 bat h 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 cloc kwise 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 Controller Setup, Safety Set Temperature).

Reservoir Fluids
Depending on your needs, a variety of fluids can be used with your Circulator. No matter what bath fluid is
selected, it must be chemically compatible with the reservoir and the materials in your 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.

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.

properly, contact the supplier from whom the unit was purchased. Have the following information

• Supplier’s order number or invoice number
• A summary of the problem
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
PARTICULAR PURPOSE WHICH EXTEND BEYOND THE DESCRIPTION AND PERIOD AS STATED
IN THE OPERATOR’S MANUAL INCLUDED WITH EACH PRODUCT.
LIMITATION ON DAMAGES. THE MANUFACTURER’S SOLE OBLIGATION UNDER THE WARRANTY
IS LIMITED TO THE REPAIR OR REPLACEMENT OF A DEFECTIVE PRODUCT AND POLYSCIENCE
SHALL NOT, IN ANY EVENT, BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES
OF ANY KIND RESULTING FROM USE OR POSSESSION OF THIS PRODUCT.
Some states do not allow: (A) limitations on how long an implied warranty lasts; or (B) the exclusion or
limitation of incidental or consequential damages, so the above limitations or exclusions may not apply to
you. This warranty gives you specific legal rights and you may have other rights that vary from state to
state.
