space (clearances) for period-
ic servicing. For op mal water
heater e
ffi
ciency, the unit must have
unrestricted air
fl
ow and requires a

has an 8 foot tall ceiling and is 10 feet
long by 8-3/4 feet wide would contain
700 cubic feet.

Avoid loca ons such as a cs,
upper
fl
oors, or where a leak
might damage the structure
or furnishings. Due to the normal
corrosive ac on of water, the tank will
eventually leak. To minimize property
damage from leaks, inspect and
maintain your water heater in accor-
dance with this manual’s instruc ons.
Inspect the drain pan, pipes, and
surrounding area regularly and
fi
x any
leaks found. Drain pans are available at
your local plumbing supplier. Leaks are
frequently in the plumbing system
itself and not the water heater.
7
The unit cannot be placed into
any type of closet or small
enclosure, unless adequate
provisions are made for air exchange
(vented or louvered doors, etc.).
8
To ensure op mal perfor-
mance and servicability, a
minimum clearance of 6
inches must be maintained from all
sides and 6 inches from the top for
access to the air
fi
lter.
9
Water heaters located in
uncondi oned spaces (i.e.,
garages, basements etc.) may
require the water piping, condensate
piping, and drain piping to be insulated
to guard from freezing.
10
The air
fi
lter, condensa on
drain and controls must be
easily accessable for opera-
on and service.
11
The site loca on must be
free from any corrosive
elements in the atmosphere
such as sulfer,
fl
uorine, sodium and
chlorine. These elements are found in
aerosol sprays, detergents, bleaches,
air fresheners, paint and varnish
removers, refrigerants and many other
household products. In addi on,
excessive dust and lint may e
ff
ect the
opera on of the unit, see the Air Filter
Maintenence sec on in this manual.
12
The ambient air temperature
must also be considered when
installing this unit. In E
ffi
ciency
Mode the air temperature needs to be
above 45
°
F/7.2
°
C and below
120
°
F/48.8
°
C for heat pump opera on.
If the air temperature falls outside
these upper and lower limits, the
electrical elements will ac vate to meet
the hot water demand and the heat
pump does not operate in either
E
ffi
ciency or Hybrid Mode.
