Electrical Connections
Before any electrical connections are attempted, be sure the water heater is
full of water and that the manual shut-off valve in the cold water supply line is
open. Heating elements, which have been energized for a very short period
of time, can be damaged (burned-out) if they are not completely immersed in
water. This warranty DOES NOT cover burned-out heating elements. Check
the rating plate and wiring diagram before proceeding. This electric water
heater was manufactured and wired in acc
ordance with the ETL 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. The plumbing
supplier in your area ordered this water 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 o
rder to meet local utility and building codes and in order to obtain
the most economical rates. All electrical connections to elements,
thermostats, contactors, fuses (certain models), and transformer have been
made at the factory. DO NOT alter any of the internal wiring. Wiring
connections may loosen during shipment. Check all connections for
tightness.
To make the wiring connections to a power supply, follow the steps below:
A) Open the cover door of the control box.
B) Bring the power leads from an adequately
fused disconnect switch (not
furnished with the water heater due to varying state and local codes) and
connect to the terminal block. Local ordinances and/or utility company
may require an increase in the gage size of the wiring for conditions where
long wiring lengths exist.
C) This water heater must be properly grounded. A ground lug is provided
within the electrical control box for connection to a properly sized ground.
(See wiring diagram for minimum required ground size. The wiring
diagram is located o
n the inside door of the control box)
D) Close the cover door of the control box.
Heating Elements
To replace heating elements, disconnect power to the water heater, drain
tank and replace element. To remove a heating element, use a screw type
element wrench (1 1/2” or 2 1/8”) available from most supply houses.
DO NOT over-tighten the new element, as this will cause distortion in the new
element gasket. Once the element has been replaced, follow the instructions
“To Fill The Water Heater”. It is imperative tha
t the water heater is full before
power is restored to the heating elements.
