INSTALLATION
4
Your satisfaction and safety require a complete understanding of this unit. Read the instructions thoroughly and be
sure all operators are given adequate training before attempting to put the unit in service.
This equipment must be used only for its intended application; any alterations or modifications will void your
warranty. Local city, county, or other ordinances may govern the use of this equipment. If you have any questions
about local requirements, please contact the appropriate local agency. The end user may perform installation.
Customer service should be contacted for operating conditions outside these limits.
Environmental Conditions
Under normal circumstances these units are intended for use indoors, at room temperatures between 18° and 40°C,
at no greater than 80% relative Humidity (at 25°C) and with a supply voltage that does not vary by more than
10% from the data plate rating. This equipment should not be operated at an altitude exceeding 2000 meters.
Installation category is II, pollution degree 2. Customer service should be contacted for operating conditions outside
of these limits.
Power Source
Check the data plate for voltage, cycle, and ampere requirements. If matched to your power source, plug the power
cord into a grounded outlet.
Voltage should not vary more than ± 10% from the data plate rating.
These units are intended for 50/60-HZ application. A separate circuit is recommended to prevent damage to the unit
due to overloading or circuit failure.
Location
In selecting a location, consider all conditions that might affect performance, such as heat from radiators, ovens,
autoclaves, etc. Avoid direct sun, fast-moving air currents, heating and cooling ducts, and high traffic areas. Allow a
minimum of 10 cm between the unit and any walls or partitions that might obstruct free airflow.
Lifting and Handling
These units can be heavy for some people and care should be taken to use appropriate lifting devices that are
sufficiently rated for these loads. Units should only be lifted from their bottom surfaces. Handles and knobs are not
adequate for lifting or stabilization. The unit should be completely restrained from tipping during lifting or transport.
All moving parts such as trays or covers should be removed during transfer to prevent shifting and damage.
Oscillation Rack
The oscillation rack is installed in the bath when packed for shipping. There is a reciprocating arm that extends from
the motor housing to the rack. An adjustable bearing is at the bath end of the arm that slides over the locking pin at
the top of the rack. This bearing must be in place over the locking pin before the rack will oscillate.
Cleaning and Decontamination
In the event hazardous material is spilled onto or into the equipment appropriate decontamination must be carried
out. If there is any doubt about the compatibility of decontamination or cleaning agents with parts of the equipment or
with material contained, please contact the manufacturer.

CONTROLS OVERVIEW
5
Figure 1. Controls Illustration
Power Switch
The Green I/O (On/Off) power switch, located in the top right hand corner of the control panel, controls all power to
the unit. It must be in the I position to be ON and illuminated before any systems are operational. The on/off switch
must remain easily accessible at all times.
Main Temperature Controller
This control is marked TEMPERATURE and consists of the digital display and UP and DOWN arrow pads for
inputting set point temperatures and calibration.
Over Temperature Safety Thermostat (OTP)
This control is marked SAFETY and is completely independent of the Main Temperature Controller. The Safety
guards against any failure of the Main Controller that would allow the temperature to rise past the set point. If the
temperature rises to the Safety set point, the Safety takes control of the heating element and allows continued use of
the water bath until the problem can be resolved or service can be arranged. The control is adjusted using a
screwdriver or a small coin. (See Setting Main Temperature Control for more information.)
Safety Light
This pilot lamp is located just above the OTP and comes ON whenever the Safety Thermostat is activated. This light
should never be on during normal operating conditions.
Reciprocating Water Bath
8
Oscillation Controller
This control is marked OSCILLATION and consists of the digital display and UP and DOWN arrow pads for inputting
selected oscillations per minute.
To enable oscillation, this switch must be in the I position. This switch DOES NOT have to be ON to adjust the
oscillation set point.
Circuit Breaker and Fuse
This control provides additional protection for the unit’s electrical circuitry against power fluctuations. The circuit
breaker (non-CE models) is adjacent to the power cord, and when tripped must be reset by pushing in the extended
button before the unit will continue to operate. The fuse (on CE models in place of the circuit breaker) is located
within the power inlet where the detachable cord set connects to the unit. When blown, the fuse must be replaced
before the unit can continue operation. Not shown in Figure 1.

OPERATION
Warning:
These baths are not intended for use as acid baths. Use as an acid bath will cause severe
damage to bath components and void your warranty. Do not use deionized water, tap water,
or chemicals. USE DISTILLED WATER ONLY.
Turning On the Unit
To turn on the unit, perform the following steps:
1. Check power supply against unit serial plate; they must match.
2. Plug service cord into the electrical outlet. If supplied with a detachable cordset, plug the female end
into the unit inlet and the male plug into the power supply. Verify that units requiring a fuse have the
fuse installed in the power inlet.
3. Fill bath to your required depth with DISTILLED WATER. DO NOT USE TAP WATER, DEIONIZED
WATER, OR CHEMICALS. Normal depth is 5 ½ inches (14 cm), but depth must be at least 2 inches
(5 cm) over the bottom of the rack. Check water level frequently, add water to appropriate levels if
needed. At higher operating temperatures, or under circumstances where a cover cannot be used, it
will be necessary to check the water level more frequently.
4. Push the Main power switch to the ON position and turn the Over Temperature Safety Thermostat to
its maximum position, clockwise.
Bath Cover
Using the bath cover supplied with your accessories will accelerate heat-up time and reduce evaporation.
The cover must be used to reach set points above 60°C. The bath cover is not designed to be airtight and
create a pressurized environment.
There is a half-inch, plugged hole at the edge of the cover. This plug can be removed and a thermometer
can be inserted using the small thermometer clip when calibrating with the cover on. The larger clip is for
calibrating without the cover. See Figure 2 for placement of these clips.
Setting Main Temperature Control
To enter set point mode on the control, push and release either the UP or DOWN arrow pad one time and
the digital display will start to blink from bright to dim. While blinking, the digital display shows the set
point that can be changed using the UP or DOWN arrow pads. If the arrow pads are not pressed for five
(5) seconds, the display will stop blinking and will revert to reading the actual temperature in the bath.
Allow at least two (2) hours for the temperature to stabilize.
Warning:
Note:
If the tank boils dry while containing plastic ware, the plastic will melt. If you intend to use
test tube racks, remember that plastic coated wire racks may wear and expose metal that
can cause damage. Preferably, use all plastic racks.
The heating element of this bath does not contact the tank bottom and will not burn out if the tank
is allowed to run dry. However, a tank going dry may strain interior surfaces so this should not be
allowed to occur.
Reciprocating Water Bath

Calibrating the Main Temperature Control
We recommend that you calibrate your unit once it has been installed in its working environment and the
chamber temperature has been stable at the set point for several hours.
1. Place a calibrated reference thermometer in the bath (a thermometer clip is provided with the
accessories package). Allow the thermometer to reach temperature and remain stable for one (1)
hour.
2. Compare the reading on the reference thermometer with the temperature control display. If there is a
difference, put the display into calibrate mode by pressing both the UP and DOWN arrow pads at the
same time until the two (2) outside decimal points begin to blink.
3. When the decimal points are blinking, press the UP or DOWN arrow pad to adjust the display to
match the reference thermometer. If the arrow pads are not pressed within five (5) seconds the
display will revert to showing the temperature within the bath.
4. Allow the unit to stabilize again, and repeat calibration if necessary.
Setting the Over Temperature Safety Thermostat
To set the Over Temperature Safety Thermostat, perform the following steps:
1. Verify that the Safety Thermostat was set to its maximum position to allow the water bath to stabilize.
2. Turn the Safety Thermostat counterclockwise until the Safety indicator light turns on.
3. Turn the Safety Thermostat clockwise until the Safety indicator light turns off.
4. Turn the thermostat clockwise again, two of the smallest divisions on its scale past the point where the
indicator light went out. This will set the Safety Thermostat at approximately 1°C above the Main
Temperature set point.
Setting Oscillation Control
The oscillation switch DOES NOT need to be ON to adjust oscillation set point (see Oscillation
Controller). To enter the set point mode on the control, push and release either the UP or DOWN
arrow pad one time and the display will start to blink on and off.
While blinking, the digital display is showing the RPM (Rotations Per Minute) set point, which can be
changed by pushing the UP and DOWN arrow pads. The range for this set point is 20 - 200 RPM. If the
arrow pads are not pressed for five (5) seconds, the display will stop blinking and revert to its original RPM
value.
Setting Samples in Place
With the bath temperatures and oscillation set points adjusted, the unit is ready for operation.
1. Place samples on the oscillation rack as desired.
2. If you are using flask clamps on your oscillation rack, remove the rack and place samples in clamps
then put the rack back in place (see Oscillation Rack).
3. Put the bath cover in place if desired and turn the oscillation switch to the ON position.
