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 8 for mixing valve usage.
Figure 9 shows the attachment of the water piping to the water
heater. The water heater is equipped with 3/4” water connections.
FIGURE 8.
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.
