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 (Proportional Integral Derivative) microprocessor control
system provides proportional heat control by anticipating the approach to your set point temperature
and reducing 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.

Read all instructions pertaining to safety, setup and operation. Proper operation is the user’s
responsibility.
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:
• 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 or acceptable
media 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 media 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 or media 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.
CAUTION: If the equipment is used in a manner not specified by
the manufacturer, the protection provided by the equipment may
be impaired.

Your Water Bath is designed to be simple to setup and install. All that is required is a container for
adding water or another suitable fluid or dry medium 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,
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; extension cords increase the potential for low line voltage-related problems.
Adding Liquid to the Bath Reservoir
Fill bath so that the liquid level is approximately one inch (2.54 cm) from top when samples are placed
in the bath.

(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.
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 should not damage the heater, but may
cause permanent discoloration of the tank and inaccurate temperature information.
Distilled water is preferred for temperatures from 10° to 90°C (50° to

The preset function is a powerful feature that allows the user to design a program or setting for easy
access and repeatability. A preset gives the user one-touch access to frequently used settings, allowing
for quick start-up and easy use.
Presets consist of two parts:
• Temperature
The set temperature for the Preset.
• Time
The length of time the Preset Temperature will be maintained. The countdown will not
begin until the correct temperature has been reached. When the time elapses, the
heater will shut off and the Bath will be placed into Eco Mode. In Eco Mode, the
measured temperature will be displayed for one hour. After one hour, the Bath will be
placed into Standby Mode. If time is set to ∞, the Preset Temperature will run
indefinitely.

Stay within the fluid’s normal range for best temperature stability and low vaporization. At fluid’s high
temperature extreme:
• A fume hood may be required to prevent the buildup of vapors inside the room.
• Fluid loss from vapor will have to be frequently replenished.
• Caution must be taken to stay well below the fluid’s flashpoint.
Application Notes
• For optimum results, maintain fluid level throughout the operating period, adding fluid as
needed. Attempt to refill fluid at same temperature as bath.
• Use the bath lid and/or hollow plastic floating balls (part number 060301) to help prevent heat
and vapor loss.
• This unit is designed for indoor use only with an allowable ambient temperature between +5°C
to 40°C (41° to 104°F) and relative humidity not greater than 80%.
• Automotive antifreeze with additives**
• Hard tap water**
• Treated water that has been deionized or ultra-purified with a
specific resistance of >1 meg ohm (including but not limited to
deionized water, MQ water, ultrapure water)
• Any flammable fluids
• Concentrations of acids or bases
• Solutions with halides: chlorides, fluorides, bromides,
iodides or sulfur
• Bleach (Sodium Hypochlorite)
• Solutions with chromates or chromium salts
• Glycerine
• Syltherm fluids
** At temperatures above 40°C, additives or mineral deposits
can adhere to the stainless steel reservoir. If deposits are
allowed to build up, the heater may overheat and fail. Higher
temperatures and higher concentrations of additives will hasten
deposit build up.
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.

Draining the Bath Reservoir Water Baths with 10, 20 and 28
liter reservoirs have a drain port located on the rear of the unit. To
drain fluid from the bath reservoir, place a suitable container
beneath the drain port and remove the cap and o-ring.
WARNING: Be sure to reinstall the cap on the drain outlet before
refilling the bath reservoir. Always verify the o-ring is properly

Cleaning the Bath
Thoroughly clean the bath before each use. Use only mild soap and water when cleaning. Do not use
steel wool as damage to the unit may result. Non-steel scouring pads are acceptable. The entire unit is
housed in a tough, well-insulated powder-coated steel casing that is corrosion and chemical resistant.
Fault Screens
Fault screens will appear when the unit is not operating within normal parameters. All fault screens will
clearly indicate the issue. The fault screen will remain until the issue is resolved. The Main Menu is
accessible from the fault screen, if any adjustments are necessary.

automatically at the set point temperature once power is restored. A notification will appear on the
display to
alert you that there was a power disruption. To clear the message, press .
Resetting the Over-Temperature / Low Liquid Level Safety
For optimal protection, your Water Bath incorporates redundant over-temperature safeties. These overtemperature / low liquid level safeties automatically removes power from the heater in the event that the
bath temperature exceeds their factory set temperature settings.
While these safeties are designed to automatically reset when the bath returns to a temperature below
the factory set safety settings, we recommend that you take the following actions when the overtemperature / low liquid level warning is activated:
1. Press to place the Water Bath in the Standby mode.
2. Allow the liquid in the Water Bath to return to ambient temperature.
3. If the liquid level in the bath is too low, add liquid as required.
Check that power cord is
plugged into an operating
electrical outlet.
Check that Mains Switch on the
rear of the unit is in the On
position.
Place mains switch on back of
unit in off position, then place
mains switch on back of unit in on
position.
Check set point temperature;
