Electric Heating Element

Heating element installation
This section applies to CVSA DHW storage tanks
equipped with an electric heating element.
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. Thermostats are factory
set and wired in accordance with the wiring diagram.
The dealer 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 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 wattage and
rated voltage are shown on the water heater data plate.
IMPORTANT
The water heater must be well grounded.
A green ground screw is provided at the electrical
connection point for connecting a ground wire.
WARNING
Confirm that all electrical connections are unpowered
before installing or servicing electrical components /
connections within the water heater.
WARNING
The water heater must be electrically grounded in
accordance with local codes or, in the absence of local
codes, with NFPA 70. Failure to properly wire electrical
connections may result in serious physical harm.
Electrical power may be from more than one source.
Make sure all power is off before attempting any
electrical work.
Screw-in heaters are standard horizontal positioned.
Only a torque wrench shall be used to mount the heating
element. The torque must not exceed 59 lb.ft
(80 Nm).
CAUTION
Screw-in heaters must be installed by an authorized
specialist. The tank must be connected durably and
reliable with the ground wire connection.
Heating element wiring
Determine voltage and wattage from the rating plate
attached to the solar water heater. All external wiring,
connection, and over current protective devices must
be provided and installed in accordance with the latest
edition of the National Electrical Code, local codes, and
local utility requirements. The solar water heater must
be electrically "grounded" by the installer. A green
ground screw has been provided on the solar water
heater's junction box.
IMPORTANT
Connect the screw head with ground wire connection.
The grounding electrode conductor shall be of copper,
aluminum, or copper clad aluminum. The material shall
be resistant to corrosion, and shall be of one continuous
length without a splice or joint. Rigid metal conduit,
intermediate metal conduit, or electrical metallic tubing
may be used for the grounding means if conduit or tubing
is terminated in fittings approved for grounding.
Flexible metal conduit or flexible metallic tubing shall be
permitted for grounding if all the following conditions are
met:
The length in any ground return path does not exceed
■
6 ft. (1.8 m)
The circuit conductors contained therein are protected
■
by over current devices rated at 25 amperes or less.
The conduit or tubing is terminated in fittings approved
■
for grounding.
WARNING
Never use this water heater /storage unit unless it is
completely filled with water
