DESCRIPTION
WHITE-RODGERS
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.
