!
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.
!
WARNING: If local
codes require external
application of insulation
blanket kits the
manufacturer's instructions
included with the kit must
be carefully followed.
Electrical Connections continued...
A separate branch circuit with copper
conductors, over current protective
device and suitable disconnecting
means must be provided by a qualified
electrician.
All wiring must conform to local
codes or latest edition of National
Electrical Code ANSI/NFPA 70.
The water heater is completely wired
to the Electrical Power Hookup
Terminals inside the jacket at the top
front of the water heater. An opening
for 1/2" or 3/4" electrical fitting is
provided for field wiring connections.
The voltage requirements and wattage
load for the water heater are specified
on the rating plate on the front of the
water heater.
Insulation Blankets
Insulation blankets, available to
the general public, for external
use on electric water heaters are
not necessary. The purpose of an
insulation blanket is to reduce the
standby heat loss encountered with
storage tank heaters. This water
heater meets or exceeds the National
Appliance Energy Conservation Act
standards with respect to insulation
and standby loss requirements making
an insulation blanket unnecessary.
The manufacturer's warranty does not
cover any damage or defect caused by
installation, attachment or use of
any type of energy saving or other
unapproved devices (other than those
authorized by the manufacturer) into,
onto or in conjunction with the water
heater. The use of unauthorized energy
saving devices may shorten the life of
the water heater and may endanger life
and property.
The manufacturer disclaims any
responsibility for such loss or injury
resulting from the use of such
unauthorized devices.
The branch circuit wiring should include
either:
Metallic conduit or metallic
sheathed cable approved for use
as a grounding conductor and
installed with fittings approved
for the purpose.
Non-metallic sheathed cable,
metallic conduit or metallic
sheathed cable not approved for
use as a ground conductor shall
include a separate conductor for
grounding. It should be attached
to the ground terminals of the
water heater and the electrical
distribution box.
• 208-230V 1PH
• 24.0 Max. AMP draw
• 10 gauge wire
• Recommended 30 AMP over-
current protection.
! CAUTION: If local codes require
the application of an external
insulation blanket to this water
heater, pay careful attention to the
following so as not to restrict the
proper function and operation of the
water heater:
Do not cover the operating or

warning labels attached to the water
heater or attempt to relocate them
on the exterior of insulation blanket.
Do not apply insulation to the top of

the heat pump.
Do not cover the coils around the

sides of the heat pump.
Do not cover the Temperature

Control, temperature and pressure
relief valve or drain valve.
Inspect the insulation blanket

frequently.
