8. OUTDOOR UNIT INSTALLATION MANUAL
Engineering Data book
Installation Place
WARNING
Install the outdoor unit properly at a place that is
durable enough to the weight of the outdoor unit.
Insufficient durability may cause the outdoor unit to fall,
which may result in injury.
CAUTION
Do not install the outdoor unit at a place subject to
combustible gas leak.
Accumulation of combustible gas around the outdoor
unit may cause a fire.
Install the outdoor unit at a place that meets the
following conditions after customer’s consent is
obtained.
• A well-ventilated place free from obstacles near the
air inlets and air outlet
• A place that is not exposed to rain or direct sunlight
• A place that does not increase the operating noise or
vibration of the outdoor unit
• A place that does not cause any drainage problem
with discharged water
Do not install the outdoor unit at the following
places.
• A place full of saline atmosphere (coastal area) or
sulfide gas (hot-spring area)
(Special maintenance is required.)
• A place subject to oil, vapor, oily smoke, or corrosive
gas
• A place where organic solvent is used
• A place where high-frequency equipment (including
inverter equipment, private power generator,
medical equipment, and communication equipment)
is used
(Installation in this place may cause malfunction of
the Air to Water Heat Pump, abnormal control or
problems due to noise to such equipment.)
• A place where the discharged air of the outdoor unit
blows against the window of the neighboring house
• A place where the operating noise of the outdoor unit
is transmitted
• When the outdoor unit is installed in an elevated
position, be sure to secure its feet.
• A place where the drain water does not make any
problem.
CAUTION
1. Install the outdoor unit at a place where
discharge air is not blocked.
2. When an outdoor unit is installed in a place that
is always exposed to a strong wind like a coast
or on a high storey of a building, secure a
normal fan operation by using a duct or a wind
shield.
3. When installing the outdoor unit in a place that
is constantly exposed to a strong wind such as
the upper stairs or rooftop of a building, apply
the windproof measures referring to the
following examples.
1) Install the unit so that its discharge port faces
to the wall of the building.
Keep a distance 500 mm or more between the
unit and the wall surface.
2) Supposing the wind direction during the
operation season of the Air to Water Heat
Pump, install the unit so that the discharge port
is set at right angle to the wind direction.
• When using an Air to Water Heat Pump under low
outside temperature condition (Outside temp.:-5 °C or
lower) with COOL mode, prepare a duct or wind shield
so that it is not affected by the wind.
