Installation and Startup
Your Circulating Bath with Advanced Digital Temperature Controller is designed to be simple to set-up
and install. The only tools required are a No.1 Phillips-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: 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:

The liquid in the reservoir should be maintained at a depth between 1 inch / 2.54 cm and 3.0 inches / 7.6
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.
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.
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 a hose clamp (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
inch NPT to M16 stainless steel male adapter fittings are provided with all 50Hz models.
110-513 PSC/EN 16
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.
®
fittings are recommended. ¼
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 pressure 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.

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).

Communication
The Advanced Digital Controller features a variety of connectivity options. Following are some typical
ways you can use them to monitor and control the operation of your Circulator.
110-513 PSC/EN 20
USB Communication
Two USB ports (A and B) are provided on the rear of the Temperature Controller. USB A is intended for
use with a flash drive and allows you to easily log temperature data. USB B allows you to remotely
monitor and control your Circulator using a computer. See Normal Operation, Selecting a Remote
Communication and Control Protocol and the Technical Information section of this manual for additional
information.
Ethernet
An Ethernet port is provided on the back of the Temperature Controller to enable you to connect your
Circulator to a computer network. See Normal Operation, Selecting a Remote Communication and
Control Protocol and the Technical Information section of this manual for additional information,
RS232 / RS485 Serial Communication
CAUTION: Always turn electrical power to the Circulator OFF before making a connection to the
serial (DB9) port.
Your Circulator features RS232 / RS485 serial communication for remote data logging and control
capability. A DB9 connector is provided on the rear of the Temperature Controller for this purpose. See
Normal Operation, Selecting a Remote Communication and Control Protocol and the Technical
Information section of this manual for additional information.
The serial interface should be connected to a serial communication port on a remote PC using an
appropriate cable. Information on the RS232 / RS485 command and communication protocol can be
found in the Technical Information section of this manual.
External (P2) Temperature Probe
Your Circulator is capable of controlling temperature based on either the temperature of the internal bath
or that of an external vessel or device. The connection for the optional external temperature probe is on
the rear of the Temperature Controller. The Temperature Controller automatically detects the external
temperature probe when it is connected. See Replacement Parts & Accessories for available lengths and
part numbers.

Safety Set Thermostat
This is a “Do Not Exceed” temperature setting for your Circulator and is the temperature at which the
heater will be turned OFF should the liquid level in the bath drop too low or the heater malfunctions. It is
normally set about 5° higher than the desired operating temperature. Setting the Safety Set temperature
is a simple 3-step procedure.
WARNING: The Safety Thermostat is user-adjustable from approximately 100° to 220°C / 312° to
428°F. Do not force the indicator dial beyond the stops at either end of the dial’s range.
