The loca on has adequate
space (clearances) for period-
ic servicing. For op mal water
heater effi ciency, the unit must have
unrestricted airfl ow and requires a
minimum installa on space of 700 ³
(19.8m³). As an example, a room that
has an 8 foot tall ceiling and is 10
(3m) long by 8.75 (2.6m) wide would
contain 700 ³ (19.8m³).
NOTICE: This Heat Pump Water Heater
may be located within a required mini-
mum of 6in. (150mm) clearance from
a wall on the outlet side, however for
future service considera ons, a mini-
mum of 3 (900mm) from any
obstruc on on the back, le and right
side is recommended.

The fl 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 by vehicles,
fl ooding, or other risks.
6
Avoid loca ons such as 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 serviceability, a
minimum clearance of 6
inches must be maintained from all
sides and 6in (150mm) from the top
for access to the air fi lter.
9
The air fi lter, condensa on
drain and controls must be
easily accessible for opera on
and service.
10
The site loca on must be
free from any corrosive
elements in the atmosphere
such as sulphur, 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 eff ect the
opera on of the unit, see the Air Filter
Maintenance sec on in this manual.
11
The ambient air temperature
must also be considered when
installing this unit. In Effi ciency
Mode the air temperature needs to be
above 45°F/7 °C and below 120°F/ 49°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 Effi ciency or Hybrid
Mode.
