3. Installation
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. Installation may be performed by the end user. It is unnecessary for this unit
to be installed by a technician.
Under normal circumstances this unit is intended for use inside, at room temperatures between 5°C 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%. Customer Service
should be contacted for operating conditions outside of these limits.
Power Source
The electrical supply to the unit must conform to all national and local electrical
codes. The power source must match the voltage and ampere requirements listed
on the dataplate. Consult the units serial data plate for the voltage and ampere
requirements before making connection. Plug the cord into a grounded outlet.
The voltage of the outlet should not vary more than 10% from the dataplate rating.
A separate circuit is recommended to preclude loss of product due to overloading or
circuit failure.
Location
When selecting a location for this unit, consider all conditions which might affect
performance, such as heat from radiators, ovens, autoclaves, etc. Avoid direct sun,
fast-moving air currents, heating/cooling ducts and high-traffic areas. Allow a
minimum of 5 cm between the unit and surrounding walls and partitions which
might obstruct free air flow.
Lifting / Handling
These units may 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 racks and covers should be removed and
doors need to be positively locked in the closed position during transfer to prevent
shifting and damage.
Gable Cover
Using the gable cover will accelerate heat-up time, ensure stability, and reduce evaporation. The cover must be used to reach set points above 60°C. Note that the cover
is not designed to be air tight or create a pressurized environment.

4.0 Control Panel Overview (Analog Models 12501-00 to 12500-35)
Power
The main power I/O (on/off) switch controls all power to the bath. It must be in the
I or ON position and illuminated before any systems are operational.
Temperature Controller
This control is marked Temperature. It controls your selection of water bath operat-
ing temperature on a scale of 0 to 10. This scale does not represent temperature, but
is to be used as a reference guide. The operating range is 5°C above ambient to
100°C.
Heating Indicator
This pilot lamp is marked Heating and is ON when the Main Temperature
Controller is energizing the heating element. The element will cycle on and off as
needed to maintain the set point temperature.
