FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
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.)
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.
WARNING
!
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.

INSTALLATION INSTRUCTIONS
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.
To prevent electrical shock and/or equipment
damage, disconnect electric power to system at
main fuse or circuit breaker box until installation
is complete.
Label all wires prior to disconnection when ser-
vicing controls. Wiring errors can cause improper
and dangerous operation.
Following installation or replacement, follow
appliance manufacturers' recommended instal-
lation/service instructions to insure proper op-
eration.
