8. OUTDOOR UNIT INSTALLATION MANUAL
„ Installation Location
CAUTION
Install the outdoor unit in a location that meets the
following conditions after the customer's consent is
obtained.
• A well-ventilated location free from obstacles near the
air inlets and air outlet
• A location that is not exposed to rain or direct sunlight
• A location that does not increase the operating noise
or vibration of the outdoor unit
• A location that does not produce any drainage
problems from discharged water
Do not install the outdoor unit in the following
locations.
• A location with a saline atmosphere (coastal area) or
one that is full of sulfide gas (hot-spring area) (Special
maintenance is required.)
• A location subject to oil, vapor, oily smoke, or
corrosive gases
• A location in which organic solvent is used
• A location where high-frequency equipment (including
inverter equipment, private power generator, medical
equipment, and communication equipment) is used
(Installation in such a location may cause malfunction
of the air to water heat pump, abnormal control or
problems due to noise from such equipment.)
• A location in which the discharged air of the outdoor
unit blows against the window of a neighboring house
• A location 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 location in which drain water poses any problems.
1. Install the outdoor unit in a location where the
discharge air is not blocked.
2. When an outdoor unit is installed in a location
that is always exposed to strong winds like a
coast or on the high stories of a building, secure
normal fan operation by using a duct or wind
shield.
3. When installing the outdoor unit in a location
that is constantly exposed to strong winds such
as on the upper stairs or rooftop of a building,
apply the windproofing measures referred to in
the following examples.
1) Install the unit so that its discharge port faces
the wall of the building.
Keep a distance 500 mm or more between the
unit and wall surface.
2) Consider the wind direction during the
operational season of the Air to water Heat
Pump, and install the unit so that the discharge
port is set at a right angle relative to the wind
direction.
Strong wind
• When installing the unit in an area where snowfalls
may be heavy, take steps to prevent the unit from
being adversely affected by the fallen or accumulated
snow.
• Either make the foundation higher or install a
stand (which is high enough to ensure that the
unit will be above the fallen or accumulated
snow) and place the unit on it.
• Attach a snow shield (locally procured).
