Introduction

Thank you for choosing a PolyScience 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.

WARNING: PolyScience 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.

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 Instruction Manual is designed to guide you quickly through the process. We recommend that you read it thoroughly before you begin.

Safety Recommendations

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:

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.

•Always keep within the 85°C maximum operating temperature limit if using a polycarbonate open bath tank.

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.

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.

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.

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.
