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.

Resetting the Over-Temperature/Low Liquid Level Safety
Also see Display Messages and Alarms (page 14) and the
Troubleshooting Chart (page 16).
For optimal protection, your Water Bath incorporates redundant over-
temperature safeties. These over-temperature/low liquid level safeties
automatically remove 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 over-
temperature/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 cool to ambient temperature.
3. If the liquid level in the bath is too low, add liquid as required.
4. Press .
If the problem persists, contact the factory.

Troubleshooting Chart
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.

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.
!
Stay within the uid’s normal range for best temperature stability and low
vaporization. At uid’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 uid’s ashpoint.
Application Notes
For optimum results, maintain uid level throughout the operating period,
adding uid as needed. Attempt to rell uid at same temperature as
bath.
Use the bath lid and/or hollow plastic oating 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%.
