before making the conversion to 5500 watts, check the (1)
power supply . . . must be 240 volts, (2) wiring . . . 10 gauge
AWG @ Type TW, 60°C or equivalent, and (3) Circuit breakers
or fusing . . .capable of 30 amp loading. Also, the installation
must conform with this manual, local codes and electric utility
rules. Failure to comply can result in DEATH, SERIOUS bODILy
INjURy, OR PROPERTy DAMAGE.

NOTE: Whether or not the element conversion is made the
model rating plate must be marked. Using a hard point ink pen,
check the appropriate block within the model rating plate, which
is located adjacent to the lower access panel.
Water Piping
HOTTER WATER CAN SCALD: Water heaters are intended
to produce hot water. Water heated to a temperature which
will satisfy clothes washing, dish washing, and other sanitizing
needs can scald and permanently injure you upon contact.
Some people are more likely to be permanently injured by
hot water than others. These include the elderly, children, the
infirm, or physically/mentally handicapped. If anyone using hot
water in your home fits into one of these groups or if there is a
local code or state law requiring a certain temperature water at
the hot water tap, then you must take special precautions. In
addition to using the lowest possible temperature setting that
satisfies your hot water needs, a means such as a mixing valve,
should be used at the hot water taps used by these people or
at the water heater. Mixing valves are available at plumbing
supply or hardware stores. Follow manufacturers instructions
for installation of the valves. before changing the factory setting
on the thermostat, read the “Temperature Regulation” section
in this manual.
See Figure 7 for mixing valve usage.
FIGURE 7.
Figure 8 shows the attachment of the water piping to the
water heater. The water heater is equipped with 3/4” water
connections.
If a water heater is installed in a closed water supply system; such
as one having a back-flow preventer, check valve, water meter
with a check valve, etc... in the cold water supply; means must
be provided to control thermal expansion. Contact the local utility
or Sears Service Center on how to control this situation.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the water inlet connection.
Do not solder the water supply lines directly to the cold water
inlet. It will harm the dip tube and damage the tank.
NOTE: To protect against untimely corrosion of hot and cold
water fittings, it is strongly recommended that di-electric
unions or couplings be installed on this water heater when
connected to copper pipe.
