Rheem AP15121-1 - Manual (Page 9)

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.
! 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 access door to
temperature control, temperature and
pressure relief valve or drain valve.
 Inspect the insulation blanket
frequently.
! WARNING: If local
codes require external
application of insulation
blanket kits the
manufacturer’s instructions
included with the kit must
be carefully followed.
Insulation Blankets
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.
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.
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.
