1.2 Unpacking

Your circulator is shipped in a special carton. Retain the carton and all packing materials until the unit is completely assembled and working properly. Set up and run the unit immediately to confirm proper operation. Beyond one week, your unit may be warranty repaired, but not replaced. If the unit is damaged or does not operate properly, contact the transportation company, file a damage claim and contact the company where your unit was purchased.

Remove any loose packing material which may have fallen into the reservoir during shipping. Also check that nothing remains around the heater or circulator pump. Before proceeding, be sure the Power switch is in the OFF position. Refrigerated models should have the Cooling switch in the OFF position.

Note:

Work area "opening" is designed to measure samples directly in the bath. If additional viscometer height is required (spindle/guard clearance), either a 4 inch rod extension (part number BLM-4E)used with type A lab stand or an 18 inch rod replacement (part mumber VS-38)used with type S lab stand are available from Brookfield or an authorized dealer.

1.4 Description of Circulating Bath

Digital controller refrigerated and heating circulating baths are designed to provide precise temperature control of fluids for closed loop circulation to external equipment or to be used as a stand alone bath. The reservoir may be used for immersing samples while the unit is connected to an external device. All wetted parts are corrosion resistant 300 series stainless steel. Models are equipped with various size reservoirs.

1.6 Circulating Bath Fluid Connections To External Apparatus

On circulating baths, the pump inlet and outlet are internally threaded with female 1/4inch NPT to allow use of barbed tubing adapters or hard plumbing. Or, you can slide each pipe and hold it in place with a hose clamp.

Select tubing and fittings that are compatible with bath fluid and temperature range. If the pump inlet and outlet are not used for external circulation, for best results connect the inlet and outlet pipes with a short length of insulated tubing. Or, plug the pipes with male nylon plugs (supplied) or with metal plugs (not supplied) for high temperature use.

The nylon barbed tubing adapter fittings supplied are for applications from -20° to 93°C. Brass, stainless steel or Teflon® fittings are recommended for applications above 93°C. Quick connectors are not recommended as they typically restrict flow rate.

Section 2. Operation

2.1 Location

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 excessively dusty areas. Refrigerated circulators must be four inches minimum away from walls or vertical surfaces so air flow 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 avoid low line voltage problems.

2.2 Filling the Reservoir

The maximum fill level is one inch below the top of the reservoir. When in operation, add additional fluid to compensate for any additional volume needed for external circulation. Minimum liquid depth is enough to fully cover the heater, pump, and one inch of the temperature sensor. If the proper fluid level is not maintained, the heater coil may become exposed and possible damage to the heater may result.

Warning: These units are equipped with Over Temperature Protection (OTP). Failure due to low

liquid level or failure to set OTP and properly immerse the heater may result in heater burnout

and triac failure. While operating, do not allow the heater to contact any potentially flammable

materials such as plastic racks or sides of plastic tanks as a fire hazard may result.
