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.
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 bead in the tank. Always allow the unit to cool
before attempting to move it.
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.
Units are cleaned at the factory, but not sterilized. Remove any beads if assembled and clean the bath
with a disinfectant that is suitable for your application. Separately wash beads. CAUTION: Avoid using
strong acids, bases, including bleach solutions, and detergents, which can tarnish the beads. For
additional information, see MAINTENANCE for cleaning instructions and precautions.

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.
Main Temperature Controller
This control consists of the digital display and UP and DOWN arrow pads for inputting set point
temperatures and calibration.
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 fuses must be in place for the unit to operate. Please contact
customer service for more information.
Over Temperature Thermostat (OTL)
This controller is marked “Safety” 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 bead 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.
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 Thermostat has been activated. Under normal operating
conditions this light should never be on.
