STEPS TO INSTALL YOUR WATER HEATER (Continued)
TIME SWITCH OR OFF PEAK WIRING
For TIME SWITCH or “OFF-PEAK” operation of the lower
element see either FIG. 3E or 3F wiring schematic.
CAUTION: If you are going to wire the unit for either a
TIME SWITCH or “OFF-PEAK” operation, the black wire
from Terminal No. 4 of the limit switch must be disconnected
and replaced totally or disconnected and joined with a new
section of wire using a proper connector. BE SURE TO
FOLLOW ALL LOCAL AND NATIONAL CODES AND
ELECTRIC UTILITY REQUIREMENTS WHEN MAKING THE
CONNECTIONS.
Dual element water heaters are designed to allow only one
element to heat at a time, This method is called
non-simultaneous operation and is necessary to avoid
overloading wiring in the house per the National Electric
Code. Off-Peak wiring methods must ensure proper use of
the high limit control in at least one line to each element
and use the non-simultaneous feature.
----------------------- WARNING ----------------------------
IF YOU ARE NOT FAMILIAR WITH WIRING AND YOU
HAVE ANY DOUBTS, YOU SHOULD GET HELP FROM A
LICENSED ELECTRICIAN. IF YOU DO SOMETHING
WRONG, SEVERE BURN OR SHOCK HAZARDS CAN
RESULT.
* REPLACE THE JUNCTION BOX COVER after you have
made the wiring connections.
CAUTION: DO STEP 7, PAGE 6 BEFORE TURNING ON
ELECTRICAL POWER TO THE WATER HEATER.

WATER HEATER START-UP.
To comply with safety regulations, the Kenmore Survivor
water heater is factory set to heat water to 120 degrees F. At
this temperature, water is hot enough for most household
needs. A setting of 120° F, or lower if local codes require, is
recommended as a starting point.
Safety and energy conservation are factors to be considered
when selecting the water temperature setting of water heater’s
thermostat. The lower the setting the greater the safety and
savings in energy and operating cost.
TIME/TEMPERATURE RELATIONSHIPS IN SCALDS
