Preparation
4.1
Preparing the installation site
WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
4.1.1
Installation site requirements of the
indoor unit
INFORMATION
The sound pressure level is less than 70 dBA.
▪
Air flow.
Make sure nothing blocks the air flow.
▪
Drainage.
Make sure condensation water can be evacuated
properly.
▪
Wall insulation
. When conditions in the wall exceed 30°C and a
relative humidity of 80%, or when fresh air is inducted into the
wall, then additional insulation is required (minimum 10 mm
thickness, polyethylene foam).
▪
Wall strength.
Check whether the wall or the floor is strong
enough to support the weight of the unit. If there is a risk, reinforce
the wall or the floor before installing the unit.
Install power cables at least 1 metre away from televisions or radios
to prevent interference. Depending on the radio waves, a distance of
3 metres may NOT be sufficient.
▪ Choose a location where the hot/cold air discharged from the unit
or the operation noise, will NOT disturb anyone.
▪
Fluorescent lights
. When installing a wireless user interface in a
room with fluorescent lights, mind the following to avoid
interference:
▪ Install the wireless user interface as close as possible to the
indoor unit.
▪ Install the indoor unit as far as possible from the fluorescent
lights.
It is NOT recommended to install the unit in the following places
because it may shorten the life of the unit:
▪ Where the voltage fluctuates a lot
▪ In vehicles or vessels
▪ Where acidic or alkaline vapour is present
▪ In places where a mineral oil mist, spray or vapour may be
present in the atmosphere. Plastic parts may deteriorate and fall
off or cause water leakage.
▪ In places where the unit would be in the path of direct sunlight.
▪ In bathrooms.
▪ Sound sensitive areas (e.g. near a bedroom), so that the
operation noise will cause no trouble.
WARNING
Do NOT place objects below the indoor and/or outdoor unit
that may get wet. Otherwise condensation on the unit or
refrigerant pipes, air filter dirt or drain blockage may cause
dripping, and objects under the unit may get dirty or
damaged.
▪
Spacing.
Install the unit at least 1.8 m from the floor and keep the
following requirements in mind for distances from the walls and
the ceiling:
≥50
≥50
≥30
(mm)
