Electric Water Heater Control

INSTALLATION INSTRUCTIONS

This control is a dual-function control having a tempera-
ture control in series with a high-limit control.

The temperature control is a normally closed SPST switch
which opens on a rise in temperature and will control one
heating element.

Operator: Save these instructions for future use!

PRECAUTIONS

THIS CONTROL MUST BE INSTALLED BY A QUALI-
FIED INSTALLER.

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 compo-
nents could cause the control to malfunction.

This control has been accurately calibrated at the factory.
Any attempt to re-calibrate this control will void the White-
Rodgers warranty.

Do not use on circuits exceeding specified volt-
ages. Higher voltages will damage control and
could cause shock or fire hazard.

If in doubt about whether your wiring is millivolt,
low or line voltage, have it inspected by a quali-
fied heating and air conditioning contractor or a
licensed electrician.

CAUTION

!

The limit control is a normally closed DPST switch which
opens on a rise in temperature to limit the maximum
allowable temperature. It has manual reset.

Both switches are calibrated to meet the requirements for
typical residential type storage tank water heaters.
