Electrical Connections
Before any electrical connections are made, be sure that the water heater is
full of water and that the valve in the cold water supply line is open. Check
the rating plate and wiring diagram before proceeding. This electric water
heater was built and wired in accordance with the Underwriters Laboratories
testing approvals requirements. The temperature limiting device is of the
manual reset, trip-free type and has been factory installed to interrupt all
ungrounded power supply conductors in the event of thermostat failure.
Thermostats are factory set and wired in accordance with the wiring diagram
fastened to the inside of the top access panel. The dealer in your area
ordered this heater wired at the factory to comply with existing area codes,
but local utility codes may require or allow other circuitry. Consult your local
power company to determine the correct electrical hook-up in order to meet
local utility and building codes and in order to obtain the most economical
rates. Also check to find out if you are required to obtain a permit before
starting the installation. The following chart shows the recommended fuse
size for the maximum water heater wattage. The maximum wattage and
rated voltage are shown on the water heater data plate. The water heater
must be well grounded. A green ground screw is provided at the electrical
connection point for connecting a ground wire.
