Introduction

Thank you for choosing this Water Bath. It is designed to handle a wide range of laboratory procedures,
including: incubation, inactivation, and agglutination as well as most pharmaceutical, serological,
biomedical, and industrial procedures.

To ensure optimum temperature uniformity, your Water Bath features an energy efficient, large-area
heater and thermostatic control. Its PID microprocessor control (Proportional Integral Derivative) system
provides proportional heat control by anticipating the approach to your set point temperature and

preventing overshoot. A redundant safety thermostat is standard on all models.

General Safety Information

When installed, operated, and maintained according to the directions in this manual and common safety
procedures, your Water Bath should provide safe and reliable temperature control. Please ensure that all
individuals involved in the installation, operation, or maintenance of this Water Bath read this manual
thoroughly prior to working with the unit.

This symbol marks chapters and sections of this instruction manual that are particularly relevant to
safety. When attached to the unit, this symbol draws attention to the relevant section of the
instruction manual.

This symbol indicates that hazardous voltages may be present.

This symbol marks information that is particularly important.

This symbol indicates alternating current.

This symbol on the Power Switch / Circuit Breaker indicates that it places the unit into a fully

powered state.

This symbol on the Power Switch / Circuit Breaker indicates that it disconnects power to the unit.

This symbol on the Power Switch 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.

Read all instructions pertaining to safety, set-up, and operation.

Proper operation is the users’ responsibility.

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:

• Always connect the power cord on this Water Bath to a grounded (3-prong) power outlet. Make

certain that the outlet is the same voltage and frequency as your unit.

• Never operate the Water Bath with a damaged power cord.

• Always turn the Water Bath OFF and disconnect mains power before performing any maintenance

or service.

WARNING:

• Never operate the Water Bath 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 type 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.

• Use compatible bath fluids only.

• Always drain all fluid from the reservoir before moving or lifting your Water Bath. 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.

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 Water Bath

Your water bath 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, then
contact the company where your unit was purchased.

WARNING: Keep unit upright when moving. Be sure to follow your company’s procedures and

practices regarding the safe lifting and relocation of heavy objects.

Installation and Startup

Your Water Bath is designed to be simple to setup and install. The only tools required are a flat-head
screwdriver and a container for adding water or another suitable fluid to the bath reservoir.

General Site Requirements

Locate your Water Bath on a level surface in an area that is free from drafts and wide ambient
temperature variations, such as near heater or air conditioning vents. Do not place it where there are
corrosive fumes, excessive moisture, or in excessively dusty areas.

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: Read the safety data sheet for the bath fluid being used carefully before filling reservoir.
WARNING: See Technical Information in the rear of this manual for a list of compatible liquids.
WARNING: If the proper fluid level is not maintained, the unit could possibly be damaged (fluid level

too low) or the bath may overflow (fluid level too high).

CAUTION: Fumes from acidic solutions may cause corrosion of the stainless steel reservoir. Care

should be taken to maintain a neutral pH at all times.

Fill bath so that liquid level is approximately one inch (2.54 cm) from top when samples are placed in
bath.

To ensure accurate reading of temperature, the fluid level should not be less than 2 inches (5.08 cm) from
the bottom of the unit. Operation of the bath without fluid will not damage the heater, but will cause
permanent discoloration of the tank and will not provide accurate temperature information.

Distilled water is preferred for temperatures from 10° to 90°C (50° to 194°F). A variety of fluids can be
used with the bath depending on the application. The fluid must be compatible with 300 series stainless

steel. See Technical Information, Reservoir Fluids in the rear of this manual for a list of compatible fluids.

If using water, a few drops of polyclean Algaecide (part number 004-300040) should be used to help
prevent algae formation.

WARNING: Always drain all fluid from the reservoir before moving or lifting your Water Bath. 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 Water Bath to cool completely before

cleaning or performing any maintenance.
