Electrical Connections
Before any electrical connections are made, be sure that the water heater is
full of water and that the manual shut-off 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 INTERTEK
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 plumbing supplier 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.
Ground screw on 10 & 15-gallon models is located under the removable
element cover.
