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:

Warning Label		Danger Area.
W09		Attention! Observe instructions
Colors: Yellow/black		(operating manual, safety data sheet)
Mandatory Label		Carefully read the user information prior to
M018		beginning operation.
Colors: Blue/white		Scope: EU
or
Semi S1-0701		Carefully read the user information prior to
Table A1-2 #9		beginning operation.
Colors: Blue/white		Scope: NAFTA

WARNING: See Technical Information in the rear of this manual for a list of compatible liquids. WARNING: Read the safety data sheet for the bath fluid being used carefully before filling reservoir.

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 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.

110-513 PSC/EN

15

Maximum Fluid Level =

1 inch / 2.54 cm below underside of top deck

Minimum Fluid Level =

3.0 inches / 7.6 cm below underside of 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.

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 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® 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.

110-513 PSC/EN

16

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.

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.
