Installation & Startup
Your Circulating Bath with Advanced Programmable Temperature Controller is designed to be simple to
set-up and install. The only tools required are a Philips-head screwdriver and a container for adding water
or other 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 cords is not
recommended; this will reduce the potential for problems caused by low line voltage.

Pump Inlet and Outlet Connections
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 pump inlet and outlet ports are female ¼ inch NPT connections that permit use of barbed tubing
adapters or hard plumbing fittings. ½ inch (13mm) ID tubing may also be slid over these connections and
held in place with a hose clamp.
If the pump inlet and outlet are not used for external circulation, the Bypass Tubing provided with the unit
should be left in place in order to optimize fluid mixing within the reservoir.
The nylon barbed tubing adapter fittings supplied with the unit are intended for applications from
®
-40° to 93°C. For applications above 93°C, brass, stainless steel, or Teflon
fittings are recommended. ¼
inch NPT to M16 stainless steel male adapter fittings are provided with all 50Hz models.
NOTE: The use of quick-connect fittings is not recommended as they typically restrict flow rate.
External Closed Loop Circulation
Connect the pump inlet and outlet to the external apparatus. To maintain adequate flow, avoid restrictions
in the tubing. When connecting the Circulator to more than two closed loops, the use of a manifold made
of “Y” adapters to divide the fluid into multiple banks is recommended. After setting up multiple closed
loops, check for adequate flow at the return manifold of each loop and check that the bath fluid is at an
adequate level. A booster pump may be added to closed loops without damaging the Circulator’s pump.
The temperature control stability of a closed loop system is better at the external apparatus than in the
Circulator reservoir (provided the control point of the apparatus represents a constant load and is well
insulated). For example, if you circulate fluid through a viscometer at 50°C, the temperature variation
observed in the Circulator reservoir may be ±0.1°C while the temperature variation in the viscometer may
be only ±0.05°C.
Although temperature stability is generally better at the external apparatus control point, depending on the
length of tubing used and the efficiency of the insulation, the actual temperature reading at the external
apparatus may be slightly different than the temperature reading at the Circulator reservoir.

Open Loop Circulation
The duplex (pressure/suction) pump permits circulation to and from an external open bath. To prevent
siphoning when the Circulating Bath is turned off, position both baths so that the two fluid levels are at the
same elevation.
Connect the pump inlet and outlet to the
external bath using tubing of the same
diameter and length. The same size fittings
should also be used on both the inlet (suction)
and outlet (pressure). This helps ensure a
balanced flow. A restricting valve or pinch clip
should be installed in the pressure (outlet)
tubing and adjusted to match the return
suction (inlet) flow rate. Cut the external end
of the suction tube into a “V” shape so that the
tube will not seal itself against the wall of the
external tank. Both the pressure and suction
tubing should be securely fastened to the
external tank to prevent movement during use.
When using flexible tubing, the suction tubing
must have a wall thickness that will not collapse under vacuum, particularly when going around bends.
Circulating Bath Height Regulation — Position the ends of the pressure and suction tubes at the desired
maximum fluid level in the external bath and fill the bath to that level. Fill the Circulating Bath to a height
one inch (25mm) below the top of the reservoir. Start the pump and adjust the restricting valve/pinch clip
on the outlet tubing until the liquid height in both baths remains constant. Add fluid to the baths as needed
to compensate for the fluid in the inlet and outlet lines.

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: When using Class III flammable fluids per DIN 12876-1, the user must attach the
following warning labels to the front of the unit so that they are well visible:

Colors: Blue/white
Or
Semi S1-0701
Table A1-2 #9
Colors: Blue/white
WARNING: Always use fluids that satisfy safety, health, and equipment compatibility requirements.
Be aware of the chemical hazards that may be associated with the bath fluid used. Observe all safety
warnings for the fluids used as well as those contained in the material safety data sheet.

Attention! Observe instructions
(operating manual, safety data sheet)
Carefully read the user information prior to
beginning operation.
Scope: EU
Carefully read the user information prior to
beginning operation.
Scope: NAFTA
For optimum temperature stability, the fluid’s viscosity should be 50 centistokes 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.

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.

CAUTION: External Cooling Control settings are always displayed and set in °C.
NOTE: The Circulator must be equipped with the optional external cooling control valve in order to use
this function. Refer to the instructions included with the optional External Cooling Control Valve for
installation information.
External cooling control provides you with a means of quickly cooling the bath fluid after a period of
operation at an elevated temperature. When properly configured, it also prevents the bath from cooling to
a temperature below that which is intended.
General Operation
External cooling control allows you to initiate a controlled cool down of the bath fluid after operation at an
elevated temperature by automatically and incrementally closing the valve as the bath temperature
decreases.
1. When the bath temperature is above the Maximum Set value, the external cooling valve is fully
open (100%).
2. When bath temperature is between the Maximum Set and Minimum Set values, the external
cooling valve is partially open (user-adjustable from 10% to 90%).
3. When the bath temperature is below the Minimum Set value, the external cooling valve is fully
closed (0%).
Configuring External Cooling Control
1. Select External Cooling Control from the second page of the Control sub-menu. The External
Cooling Control setup screen will appear.
