Emerson White-Rodgers 11B79-3 Installation Instructions

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE
INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL
INJURY AND/OR PROPERTY DAMAGE.
The 11B79-3 combination control is a Hot Water Control
utilizing a thermostat and an E.C.O. (Energy Cut-Off)
device. The thermostat consists of a remote sensor and an
integral sensor. It is a temperature regulating device for use
in applications not exceeding 180°F (82°C). This model is
designed for use as direct immersion. No immersion well is
required.
The E.C.O. is a non-cycling manual reset device designed
to limit the system temperature to 205°F. It is mounted in an
integral well built into the immersion fitting.
If in doubt about whether your wiring is millivolt, line or low voltage,
have it inspected by a qualified heating and air conditioning
contractor, electrician, or someone familiar with basic electricity
and wiring.
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.
CAUTION
!
Do not short on circuits exceeding specified voltage.
Higher voltage will damage control and could cause
shock or fire hazard.
