Installation Conditions For Outdoor Units; Minimum Distances For Outdoor Units - Panasonic Aquarea WH-ADC0309J3E5 Planning And Installation Manual

5.2.2.1 Installation conditions for outdoor units

The installation conditions for the outdoor unit are as follows:
● The outdoor unit is designed for outdoor installation only and must not be installed
indoors.
● For condensed water drainage in defrost mode, drainage is recommended via a drain
pipe to the frost-free ground with gravel fill (→
p. 102).
● Maintain the minimum distances (→
p. 101).
● The heat emission of the outdoor unit must not be impeded by additional protection
devices such as awnings or such.
● No objects should be put up that can cause short-circuiting of the exhaust air. Even
when using multiple outdoor units (e.g. in case of heat pump cascades), avoid any air
flow short-circuiting (→
● The operating noise of the outdoor unit must not cause any nuisance to the user or to
neighbours. In certain countries or regions, the installation of air-to-water heat pumps
may require permission. All provisions regarding noise valid at the location must be
taken into account (→
● Additional anti-vibration dampers can be used for enhanced noise isolation.
● Installing an outdoor unit near to the sea, in regions with a high content of sulphur or
at sites where large quantities of oil (e.g. machine oil, etc.) are present, may shorten
its operating lifecycle.
● The outdoor unit is to be installed on a concrete foundation or a stable ground frame,
which may be located on the outer wall of a building. Also, it must be horizontally
aligned and bolted down (ø 10 mm).
● In the case of installation locations experiencing strong winds e.g. on building rooftops
or between buildings, the outdoor unit must be additionally secured by field-supplied
means to prevent tipping over (e.g. by bracing).
