Introduction
Thank you for choosing this Water Bath. It is designed to handle a wide
range of laboratory procedures including: incubation, inactivation and ag-
glutination as well as most pharmaceutical, serological, biomedical and
industrial procedures.
To ensure optimium temperature uniformity, your Water Bath features
an energy efcient, 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.

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:
This symbol on the Power Button indicates that it places the
unit in a standby mode. IT DOES NOT fully disconnect the
unit from the power supply.
Read all instructions pertaining to safety, set-
up and operation. Proper operation is the user’s
responsibility.
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.
!
WARNING: Always allow the bath uid to cool to ambient
temperature before draining.
WARNING:
• Never operate the Water Bath without bath uid in the
reservoir. Periodically check the reservoir to ensure that
the liquid depth is within acceptable levels. Always rell
the reservoir using the same bath uid 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 uids only.
• Always drain all uid 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 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.
CAUTION: If the equipment is used in a manner not
specied by the manufacturer, the protection provided by the
equipment may be impaired.

Installation and Startup
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 uid 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
Fill bath so that the liquid level is approximately one inch (2.54 cm) from
top when samples are placed in the bath.
To ensure accurate reading of temperature, the uid level should not be
less than 2 inches (5.08 cm) from the bottom of the unit. Operation of the
bath without uid 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 uids can be used with the bath depending on the
application. The uid must be compatible with 300 series stainless
steel. See Technical Information, Reservoir Fluids (page 18) for a list of
compatible uids.
If using water, a few drops of polyclean Algaecide (part number 004-
300040) should be used to help prevent algae formation.
WARNING: Read the safety data sheet for the bath uid
being used carefully before lling reservoir.
WARNING: See Technical Information, Reservoir Fluids
(page 18) for a list of compatible liquids.
WARNING: If the proper uid level is not maintained, the unit
could possible by damaged (uid level too low) or the bath
may overow (uid 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.

Electrical Power
Insert the power cord into a properly grounded
electrical outlet.
Place the Mains Switch on the rear of the unit in the
On position. The three decimal points in the upper
readout light to indicate that the Water Bath is in the
Standby mode.
WARNING: The Water Bath’s power cord must be connected
to a properly grounded electrical receptacle. Make certain
that this electrical outlet is the same voltage and frequency as
your Water Bath. The correct voltage and frequency of your
Water Bath are indicated on the identication label on the
rear of the unit.
CAUTION: The use of an extension cord is not
recommended. If one is necessary, it must be properly
grounded and capable of handling the total wattage of the
unit. The extension cord must not cause more than a 10%
drop in voltage to the unit.
!
Controller Setup
Power On
1. Place the Mains Switch on the rear of the unit in the On position. The
three decimal points in the upper readout light to indicate that the
Water Bath is in the Standby mode.
2. Press . The actual bath temperature is displayed on the upper
readout and the set point temperature is displayed on the lower
readout. Both values are displayed to one decimal point. If the actual
bath temperature is lower than the set point temperature, the unit will
automatically begin heating and the heating symbol will light.
Selecting the Temperature Unit
1. Press until ºC or a ºF appears on the lower readout.
2. If ºC is shown, press to change it to ºF. If ºF is shown, press to
change it to ºC.
3. Press or allow the display to timeout (~10 seconds) to accept the
displayed temperature unit.

than the High Limit value, further increases will be blocked and the words
HIGH LIMIT on the LCD will ash.
1. Press until the words HIGH LIMIT appear on the LCD; the current
High Limit value will appear on the lower readout.
2. Use the and buttons to set the high limit value to the desired
temperature; this value may be set as high as 105ºC (221ºF).
3. Press or allow the display to timeout (~10 seconds) to accept the

lit.
1. Press until PRESET appears on the lower readout.
2. Use the and buttons to adjust the set point displayed on the
lower readout to the desired temperature.
3. Press until the word TIMER is displayed on the LCD; the two left
hand digits in the lower readout will begin ashing.
4. Use the and buttons to set the time duration in hours; this value
may be set anywhere from 00 to 99 hours.
5. Press again; the two right hand digits in the lower readout will
begin ashing.
6. Use the and buttons to set the time duration in minutes; this
value may be set anywhere from 00 to 59 minutes.
7. Press or allow the display to timeout (~10 seconds) to accept the
displayed Time Duration value.
