Introduction
WARNING: Brookfield Circulating Baths are not intended for directly controlling the temperature of
foods, pharmaceuticals, medicines, or other objects which may be ingested by or injected in humans
or animals. Any such objects must be isolated from contact with the bath fluid and bath surfaces.

Circulator
Thank you for choosing a Brookfield Circulating Bath with MX Temperature Controller. It is intended for
the precise temperature control of suitable liquids in a reservoir. Extremely easy to use and maintain, it
combines design innovation with highly intuitive operation to deliver convenient and versatile liquid
temperature control for a wide range of applications.
Here are some of the features that make your Circulating Bath so user-friendly:
• Simple, intuitive operation
• Displays actual and set point temperature simultaneously
• Powerful pump, easy flow adjustment
• External circulation capability
• Fully enclosed housing prevents direct contact with pump and heater, yet provides quick
access for inspection and cleaning
• Suitable for use with Class I non-flammable fluids per DIN 12876-1
It will take you very little time to get your new Circulating Bath installed and running. This Operator’s
Manual is designed to guide you quickly through the process. We recommend that you read it thoroughly
before you begin.

General Safety Information
This symbol alerts you to a wide range of potential dangers.
This symbol advises danger from electricity or electric shock.
This symbol indicates that a hot surface may be present.
This symbol marks information that is particularly important.
This symbol indicates alternating current.
These symbols on the Power Switch / Circuit Breaker indicate that they place the main power supply
ON / OFF.
This symbol on the Power Key indicates that it places the unit in a standby mode. It DOES NOT fully
disconnect the unit from the power supply.
This symbol indicates a protective conductor terminal.
When installed, operated, and maintained according to the directions in this manual and common safety
procedures, your Circulating Bath should provide safe and reliable temperature control. Please ensure
that all individuals involved in the installation, operation, or maintenance of this Circulating Bath read this
manual thoroughly prior to working with the unit.
Read all instructions pertaining to safety, set-up, operation, and maintenance.
Proper operation is the user’s responsibility.

Safety Recommendations
WARNING:
• This Circulating Bath is suitable only for use with Class I non-flammable fluids (per DIN 12876-1).
• 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.
• Use only recommended bath fluids; see Technical Information in the rear of this manual for
recommended fluids.
• Use only non-acid bath fluids.
WARNING:
• Always connect the power cord on this Circulator to a grounded (3-prong) power outlet. Make
certain that the outlet is the same voltage and frequency as your unit.
• Never operate the Circulator with a damaged power cord.
• Always turn the Circulator OFF and disconnect mains power before performing any maintenance
or service.
WARNING:
• Never operate the Circulator without bath fluid in the reservoir. Periodically check the reservoir to
ensure that the liquid depth is within acceptable levels. Always refill the reservoir using the same
bath fluid that is already in the reservoir. Bath oil must not contain any water contaminants and
should be preheated to the actual bath temperature before adding as there is an explosion hazard
at high temperatures.
• 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:
• Always allow the bath fluid to cool to ambient temperature before draining.
• The reservoir cover, top deck, and/or external pump connections may become hot with continuous
use. Exercise caution when touching these parts.
WARNING: It is the user’s responsibility to properly decontaminate the unit in the event hazardous
materials are spilled on exterior or interior surfaces. Consult manufacturer if there is any doubt
regarding the compatibility of decontamination or cleaning agents.
To prevent injury to personnel and/or damage to property, always follow your workplace’s safety
procedures when operating this equipment. You should also comply with the following safety
recommendations:

Regulatory Compliance and Testing
CAUTION: Remove any loose packing material that may have fallen into the heater/pump housing
during shipping. Before powering up, check that nothing remains around the heater or Circulator
pump.
This equipment is compliant with the European Directive 2002/95/EC and its latest amendments on
Restrictions on Hazardous Substances (RoHS) and below the given limits of hazardous substances.

Unpacking Your Circulator
Your Circulator is packed in a special carton or cartons. You should keep the packaging, along with all
packing materials, until the unit has been installed and you are certain it is working properly.
We recommend that you begin using your Circulator immediately to confirm proper operation, since
beyond one week you may be eligible for warranty repair only (rather than replacement). You’ll find
complete warranty information in the back of this manual.
In the unlikely event that the unit was damaged or does not operate properly, immediately contact the
transportation company, file a damage claim, and contact the company where your Circulator was
purchased.
