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 optimium temperature uniformity, your Water Bath features
an energy efcient, 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:
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 uid in the
reservoir. Periodically check the reservoir to ensure that
the liquid depth is within acceptable levels. Always rell
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 allow the bath uid 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

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
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 overow (uid level too high).
CAUTION: Fumes from acidic solutions may cause corrosion
!
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.
of the stainless steel reservoir. Care should be taken to
maintain a neutral pH at all times.
