Installation and Startup
Your Circulating Bath with Standard Digital 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 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.
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 4.5 inches /
11.5 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 compensate for fluid
displacement when placing samples or other materials in the Circulator’s reservoir.
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.
Maximum Fluid Level =
1 inch / 2.54 cm below underside

110-512 PSC/EN 14

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 (13 mm) ID tubing may also be slid over these connections and
held in place with hose clamps (minimum 7/8 inch / 22 mm) ID.
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.
110-512 PSC/EN 15

Refrigeration Control Connections (Refrigerating/Heating Circulators only)
Attach the Refrigeration Control Cable to the Refrigeration Control Connections on the rear of the
Temperature Controller and 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.
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.
Refrigerating / Heating Circulators
Attach the 3-ft / 0.91 m power cord to the IEC electrical connectors on the Temperature Controller (male)
and the Refrigeration Power Module (female).
Attach the 6-ft / 1.8 m power cord to the IEC electrical connection on the Refrigeration Power Module and
