Installing the water heater.
CAUTION: The presence
of water in the piping
and water heater does
not provide sufficient
conduction for a ground.
Non-metallic piping,
dielectric unions, flexible
connectors etc. can cause
the water heater to be
electrically isolated.
!
DO NOT turn on the
electrical supply or operate
this water heater unless it is
completely full of water.
Some ELD model water heaters are
equipped with a terminal block to allow
field conversion from single -phase to
three-phase and/or simultaneous to non-
simultaneous operation of the elements.
Please refer to the "Potential Field
Conversions" table in the next section to
determine the possible field conversion
configuration. Please refer to the wiring
diagram in the following sections for the
factory and field wiring of the terminal
block units. The installation must conform
to local codes or the latest edition of
National Electric Code.
GROUNDING -The branch circuit wiring
should include a separate conductor for
grounding. It should be attached to the
ground terminal of the water heater to
reduce the risk of electric shock. The water
heater must be grounded in accordance
with local codes or the latest edition of the
National Electric Code.
The terminal block configuration is
shipped from the factory as a single
phase simultaneous operation, and it is
designed to be wired to two independent
branch circuits. The first branch circuit
is connected to terminals Ll and L2, and
it must be sized according to the upper
element rating. The second branch circuit
is connected to terminals Tl and T2, and
it must be sized according to the lower
element rating. In this configuration, both
elements may turn on at the same time
during a heating cycle.
