754-1, 755-1, 756-1

Electric Water Heater Control

INSTALLATION INSTRUCTIONS

This control is designed to meet the high electrical capac-

ity requirements of electric water heaters.

The temperature control is a normally closed switch

which opens on a rise in temperature. The SPST version

(755-1) will control one heating element. The SPDT

version (756-1) will control two heating elements when

used with W-R type 755-1. (See wiring diagrams.)

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 (754-1) 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.
