INSTALLATION INSTRUCTIONS
Open on Rise – Remote Bulb
TEMPERATURE CONTROL
Fixed or Adjustable Differential
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
These controls have open on rise switch action and are de-
signed for low or line voltage heating applications with ranges
to cover such applications as curing rooms, incubators, anti-
freeze control for stock watering tanks or orchards, developing
tank, aquarium, swimming pool, etc. If the controlled medium is
a liquid, the liquid must not be corrosive to copper.
PRECAUTIONS
THESE CONTROLS MUST BE INSTALLED BY A QUALIFIED
INSTALLER.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical codes and
ordinances.
This control is a precision instrument, and should be handled
carefully. Rough handling or distorting components could cause
the control to malfunction.
This control has been accurately calibrated at the factory. Any
attempt to calibrate this control will void the White-Rodgers
warranty.
CAUTION
To prevent electrical shock and/or equipment damage,
disconnect electric power to system at main fuse or
circuit breaker box until installation is complete.
WARNING
Do not use on circuits exceeding specified voltages.
Higher voltages will damage control and could cause
shock or fire hazard.
INSTALLATION
If the manufacturer of the heating equipment has recommended
a location for the control, then follow his instructions. If none is
made, the following suggestions should be observed.
The switch mechanism of this control may be mounted in any
convenient location and the capillary should be led over a path
that will protect it from injury.
Excessive capillary should be coiled and secured close to the
switch mechanism.
The temperature sensitive element or “bulb” should be located
in the average temperature of the controlled area.
If intended to operate from air temperature, the bulb should be
located in a place where there is good circulation of air. The bulb
should be held away from the mounting surface with screw eyes
or brackets.
When intended to be immersed into a water circulating sys-
tem, such as the heating system for a swimming pool, observe
the cautions on overrun temperatures shown under SPECIFI-
CATIONS. Wells and packing nuts are available for permitting
the bulb to sense the water temperature.
If the control is to be used with a photographic processing
tank, the copper element may cause contamination if immersed
directly into the solution, resulting in a possible fogging of the
film. This may be overcome by inserting bulb into a thin stainless
steel well or plastic tubing having a slide fit over the bulb, or the
bulb may be clamped to the outside surface of the tank and then
covered with insulation to reduce the effects of variations in
room temperature.
Since the copper bulb may be harmful to the fish in an aquarium,
the bulb should be inserted in a thin, snug-fitting, stainless steel
well or plastic tubing for this application.
When the control is to be installed out of doors, such as an anti-
freeze control for stock watering tanks or orchards, the
control must be put in some rain-proof enclosure to keep water
off the switch. There should also be a good ground connection
between the case of the control and earth.
