6 Preparation
Q
Choose a location where the hot/cold air discharged from the
unit or the operation noise, will NOT disturb anyone.
Q
Heat exchanger fins are sharp and injury is possible. Choose an
installation location where there is no risk for injury (especially in
areas where children playing).
Q
Do NOT install the unit in sound sensitive areas (e.g. near a
bedroom and the like), so that the operation noise will cause no
trouble.
Note: If the sound is measured under actual installation
conditions, the measured value will be higher than the sound
pressure level mentioned in "15.10 Sound spectrum"
on
page 97 due to environmental noise and sound reflections.
It is NOT recommended to install the unit in the following places
because it may shorten the life of the unit:
Q
in coastal areas or other places where the air contains high
levels of salt. Corrosion may occur,
Q
where the voltage fluctuates a lot,
Q
in vehicles or vessels,
Q
where acidic or alkaline vapour is present.
6.1.2 Additional installation site requirements of
the outdoor unit in cold climates
Protect the outdoor unit against direct snowfall and take care that the
outdoor unit is NEVER snowed up.
Q
The unit should be installed in a way that a minimum of 15 cm
free space is assured below the bottom plate of the unit at all
weather conditions (e.g., heavy snowfall). It is recommended to
install the unit at a minimum height of 30 cm. See "7.2 Mounting
the outdoor unit" on page 27 for more details.
Q
In heavy snowfall areas it is very important to select an
installation site where the snow will NOT affect the unit. If lateral
snowfall is possible, make sure that the heat exchanger coil is
NOT affected by the snow. If necessary, install a snow cover or
shed and a pedestal.
6.1.3 Installation site requirements of the indoor
unit
Q
Mind the measurement guidelines:
Q
Mind the following spacing installation guidelines:
Do NOT install the unit in places such as:
Q
Where there is mist of mineral oil, oil spray or vapour.
Plastic parts may deteriorate, and cause them to fall out or water
to leak.
Q
Do NOT install the unit in sound sensitive areas (e.g. near a
bedroom and the like), so that the operation noise will cause no
trouble.
Note: If the sound is measured under actual installation
conditions, the measured value will be higher than the sound
pressure level mentioned in "15.10 Sound spectrum"
on
page 97 due to environmental noise and sound reflections.
Q
The foundation must be strong enough to bear the weight of the
unit. Take the weight of the unit with a domestic hot water tank
full of water into account.
Make sure, in the event of a water leak, water cannot cause any
damage to the installation space and surroundings.
Q
In places with high humidity (max. RH=85%), for example a
bathroom.
Q
In places where frost is possible. Ambient temperature around
the indoor unit should be >5°C.
