INSTALLATION

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.

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 are heavy and care should be taken to use appropriate lifting devices that are sufficiently
rated for these loads. 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.
The bottom of the unit is hot during operation as is the water in the tank. Always allow the unit to cool
before attempting to move it.

CONTROLS OVERVIEW

This section provides an overview of the panel controls. See Figure 1 for an illustration of the panel
controls.

Figure 1. Control Panel

Power Switch

The Green I/O (On/Off) power switch controls all power to the unit. It must be in the I position to be ON and the
green power on light illuminated before any systems are operational. The on/off switch must remain easily
accessible at all times. The W614M is equipped with separate switches for each tank.

Main Temperature Controller

This control is marked SET TEMPERATURE and consists of the digital display and UP and DOWN arrow pads for
inputting set point temperatures and calibration. Separate controls are used on the W614M to control temperature in
the respective tanks.

Fuses

The fuses are located at the back of the unit within the power inlet plug and 220v units also have a fuse holder
located next to the inlet. The fuses act as a circuit breaker and will cut off power to the unit if there is an electrical
surge or malfunction. The cause should be determined and corrected before placing the fuse. Fuses must be in
place for the unit to operate.

Over Temperature Limit Thermostat (OTL)

This controller is marked “Set Over Temp Control” and is completely independent of the Temperature Controller. The
OTL guards against any failure of the Temperature Controller that would allow the temperature to rise past set point.
If the temperature rises to the OTL set point, the OTL 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 OTL is manually adjusted with a
screwdriver or coin so accidental adjustment cannot occur. The W614M has separate controls for each of the tanks.

Heating Activated

This light is ON when the Temperature Controller has activated the heating element to reach and maintain set point.

Over Temperature Activated Light

This light is ON when the Over Temperature Limit Thermostat has been activated. Under normal operating
conditions this light should never be on.

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.

Attention : Ces bains d'eau ne sont pas conçus pour les acides. Utiliser un tel bain comme bain d'acide

l'endommagera gravement et annulera la garantie. Ne pas utiliser d'eau désionisée, d'eau
du robinet ni de produits chimiques. UTILISER EXCLUSIVEMENT DE L'EAU DISTILLÉE.

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. For singer or larger tank, normal depth is 5 ½ inches (14 cm), but depth
must be at least 2 inches (5 cm) over the bottom of the rack. For shallow tank, normal depth is 2/3
full, but depth must beat least 2 inches (5 cm). 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 Limit Thermostat to its
maximum position, clockwise.

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: If the tank boils dry while containing plastic ware, the plastic can melt. If you intend to use

1. Place a calibrated reference thermometer in the bath (a thermometer clip is provided with the
accessories package). (See Figure 2 for placement.) 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.

5. On the W614M, both tanks will need to be calibrated individually.

Setting the Overtemperature Limit Thermostat

To set the Over Temperature Limit Thermostat, perform the following steps:

1. Verify that the Limit Thermostat was set to its maximum position to allow the water bath to stabilize.

2. Turn the Limit Thermostat counterclockwise until the Safety indicator light turns on.

3. Turn the Limit Thermostat clockwise until the OTL indicator light turns off.

4. Turn the thermostat clockwise again, two (2) 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.

Figure 2. Thermometer Placement

Note: Water bath thermometer must be placed so that the bulb is always fully immersed. The thermometer

must not touch the sides or the bottom of the bath tank.

Bath Cover Assembly

To assemble the bath cover, perform the following steps:

1. Insert two (2) self-tapping screws through the respective cover holes and into the holes in the handle,
leaving the first self-tapping screw loose to assure proper alignment. See Figure 3. Firmly fasten both
screws into place. Do not over-tighten.
