The locaon has adequate
space (clearances) for period-
ic servicing. For opmal water
heater eciency, the unit must have
unrestricted airow and requires a
minimum installaon space of 700
³/19.8 m³. As an example, a room
that has an 8 foot tall ceiling and is 10
/3 m long by 8¾ /2.6 m wide would
contain 700 ³/19.8 m³.
 This Heat Pump Water Heater
may be located within a required mini-
mum of 6 in./15 cm clearance from a
wall on the outlet side, however for
future service consideraons, a mini-
mum of 3 /.9 m from any obstrucon
on the back, le and right side is rec-
ommended.

The oor can support the
weight of a full water heater.

Your area is not prone to
earthquakes. If it is, use
special straps as required by
local building codes.
5
The locaon is not prone to
physical damage, ooding or
other risks.
6
Avoid locaons such as upper
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 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 lter.
9
The air lter, condensaon
drain and controls must be
easily accessable for opera-
on and service.
10
The site locaon must be
free from any corrosive
elements in the atmosphere
such as sulfer, 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ect the
operaon of the unit, see the Air Filter
Maintenence secon in this manual.
11
The ambient air temperature
must also be considered when
installing this unit. In Eciency
Mode the air temperature needs to be
above 45°F/7°C and below 120°F/48°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ciency or Hybrid
Mode.
