will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury. It is also be used to alert
against unsafe practices.
The lightning flash with arrow symbol, within an equilateral triangle, is
intended to alert the user to the presence of non-insulated “dangerous
voltage” within the bath’s enclosure. The voltage magnitude is significant
enough to constitute a risk of electrical shock.
This label indicates the presence of hot surfaces.
This label indicates read the manual.
This label indicates a hand crushing hazard. (Shaking Water Bath only)
Observe all warning labels.
Never remove warning labels.
The bath’s construction provides protection against the risk of electrical
shock by grounding appropriate metal parts. The protection will not function
unless the power cord is connected to a properly grounded outlet. It is the
user’s responsibility to assure a proper ground connection is provided.
Do not use the bath as a sterile or patient connected device. In addition, the
bath is not designed for use in Class I, II or III locations as defined by the
National Electrical Code.
The circuit protector located on the rear of the bath is not intended to act
as a disconnecting means. The bath’s power cord is used as the disconnecting
device, it must be easily accessible at all times.
Never operate the bath with a damaged line cord.
Never place the bath in a location or atmosphere where excessive heat,
moisture, or corrosive materials are present.
Never operate the bath without fluid in the reservoir. The only approved fluid
is water. General Purpose Baths may also use lab armor beads.
Never operate the bath or add fluid to the reservoir with panels removed.
Operating the baths at high temperature will cause condensation on the
underside of the cover. Remove
the cover with care so the water falls back into the reservoir and not on the
bath surface.
When operating at high temperatures do not touch the cover surface, always use
the cover’s knob/handle.
The user is responsible for any hazard rising from heated material.
Do not clean the bath with solvents, only use a soft cloth and water.
Drain the bath before it is moved. Drain the bath before it is transported
and/or stored. Store the bath in the temperature range -25°C to 60°C (with
packaging), and <80% relative humidity.
Always turn the bath off and disconnect the supply voltage from its power
source before moving the bath or before performing any service or maintenance
procedures.
Transport the bath with care. Sudden jolts or drops can damage its components.
An operating shaking water bath has moving components. Do not insert
appendages between the reservoir wall and rack. We recommend stopping the
shaker table when loading/removing samples or vessels.

Chapter 3 Installation
Bath Installation
The bath is designed for continuous operation and for indoor use.
**Never place the bath in a location where excessive heat, moisture or
corrosive materials are present.
Ventilation
No special ventilation clearances are required.
Cover Installation**
Electrical Requirements
Refer to the bath’s nameplate for specific electrical requirements.
The bath is intended for use on a dedicated outlet.
The bath construction provides protection against the risk of electrical
shock by grounding appropriate metal parts. The protection will not function
unless the power cord is connected to a properly grounded outlet. It is the
user’s responsibility to assure a proper ground connection is provided.
The circuit protector on the rear of the bath is designed to protect the
bath’s internal components.
Note If the circuit protector activates allow the temperature to cool before
resetting. Restart the bath. Contact us if the circuit protector activates
again.
The bath’s electrical power cord is the disconnecting device, it must be
easily accessible at all times.
****Ensure the cord does not come in contact with the reservoir contents.
Note Before inserting the electrical cord into the bath connection ensure the
circuit protector is in the O (off) position.
Once the cord is connected to the bath, connect the other end to the main
power source.
Approved Fluids
The only approved fluids are:
Filtered/Single Distilled Water
De-ionized water
For applications requiring resistivity greater than 1 MΩ-cm or maintaining
resistivity levels greater than 1 MΩ-cm please call and speak to an
applications engineer for additional information.
Fisher Scientific takes no responsibility for damages caused by the selection
of an unapproved fluid.
When using water above 80°C closely monitor the fluid level, frequent top-offs
will be required. It will also create steam.
Filtered/Single Distilled Water
Filtered drinking water and single distilled water are good choices for heated
water baths. The filtering/distilling process removes microorganisms that are
known to cause biological fouling in water baths. The filtering/distilling
process also removes minerals and harmful particulates
from water. Microorganisms, minerals and particulates can lead to deposits and
or scaling that eventually promotes corrosion if not removed or treated.
It is also recommended to regularly drain and replace fluid especially when
higher temperatures are utilized (above 40°C). Draining and drying the bath
after each use is recommended as leaving standing water for any period of
time is known to lead to a buildup of biologic growth.
Tap Water
Usage of tap water may not cause any adverse affects on the equipment in the
short term, but in the long term problems may arise due to precipitation of
minerals and or development of algae and bacteria. Please refer to “Process
Water Quality and Standard” recommendations in this chapter for guidelines on
water usage.
Chlorine
Draining and replacing “used” water is the best preventative maintenance for
the cooling/heating equipment. Biological organisms will develop in water that
is not replaced or treated regularly. A mild treatment using an algaecide can
help extend the useful life of water.
To help alleviate bacteria or algae growth Fisher Scientific recommends the
use of small amounts of chlorine. The usage of chlorine needs to be monitored
over time in order to prevent the formation of corrosion.
The duration of time that chlorine remains in solution depends on factors such
as water temperature, pH and availability of direct sunlight. We recommend
maintaining chlorine levels at 1 to 5 ppm free chlorine. PPM levels can be
monitored using standard water quality test strips.
For best results, maintain the pH of the fluid between 6.5 and 7.5.
Do not add additional chlorine without first determining the concentration
ratio that already exists in the fluid supply. Corrosion and degradation of
the circulation components can result from concentration ratios that are too
high. Contact our customer support for additional information.
De-ionized Water
De-ionized water is water that has had its mineral ions removed using ion
exchange resins. The purpose of this process is to remove the ions that allow
electrical current to flow more easily through water. This helps to prevent
electrical leaks to ground through the recirculating fluid.
De-ionized water is in an unbalanced state and will leach the missing ions
from the materials it comes in contact with. The aggressive nature of this
leaching can cause pitting on metal surfaces. Note that the de-ionizing
process does not remove microorganisms. Because of this, we recommend de-
ionized water only with applications that have it as a specified requirement.
In any case, only de-ionized water with 1 MΩ-cm resistivity, or less, is
recommended. Recommended Biocides and Inhibitors
Fisher Scientific offers a biocide and inhibitor package Thermo 200 (Nalco)
premixed with five gallons of water or as a kit to be added to water.
****Biocides are corrosive and can cause irreversible eye damage and skin
burns.
They are harmful if inhaled, swallowed or absorbed through the skin. Refer to
the
manufacturer’s most current MSDS.

Unfavorably high total ionized solids (TIS) can accelerate the rate of
corrosion. These contaminants function as electrolytes which increase the
potential for galvanic cell corrosion.
Tap water is not normally recommended because the total ionized solids level
may be too high. As an example, tap water in the United States averages 171
ppm (of NaCl). The recommended level for use in a water system is between 0.5
to 5.0 ppm (of NaCl).
Filling Requirements
Ensure the reservoir drain port is closed and that all plumbing connections
are securely plumbed or capped. Also ensure any residue is thoroughly removed
from the reservoir before filling.
To avoid spilling, place your samples/trays into the bath before filling. Also
make allowance for splashing of water from tray oscillation movement.
Slowly fill the reservoir. When adding, point the opening of a container away
from yourself.
For Shaking Water Baths, fill the reservoir with a minimum of one inch of
water and the maximum level lower than the tray shaft fitting.
For General Purpose Baths, fill the reservoir with a minimum of one inch of
water and a maximum level one inch lower than the tank upper surface.
Note Monitor the fluid level whenever heating the fluid.
To conserve energy, reduce evaporation, and increase temperature control
accuracy, use the supplied gable cover. Do not use aluminum foil as a cover,
as it may cause corrosion due to an electrochemical reaction.
Filling with Thermal Lab Beads (GPD baths only)
Before filling the reservoir with beads ensure the reservoir plug is securely
installed into the drain.
Note Using beads derates the bath’s stability and uniformity capability.
Draining
Drain the bath before moving or storing.
Ensure the fluid is at a safe handling temperature, ~40°C or lower. Wear
protective clothing and gloves.
- Place a suitable receptacle underneath the drain.
- Slowly turn the drain plug until flow is observed.
- When the flow stops close the drain plug.
