Preparing installation site

Do NOT install the unit in places often used as work place. In case
of construction works (e.g. grinding works) where a lot of dust is
created, the unit must be covered.
Choose the installation location with sufficient place for carrying the
unit in and out of the site.
5.2.1 Installation site requirements of the
indoor unit
INFORMATION

▪ Refrigerant piping
difference). See further in this "Preparation" chapter.
INFORMATION
The sound pressure level is less than 70 dBA.
CAUTION
Appliance not accessible to the general public, install it in a
secured area, protected from easy access.
This unit, both indoor and outdoor, is suitable for
installation in a commercial
environment.
NOTICE
The equipment described in this manual may cause
electronic noise generated from radio-frequency energy.
The equipment complies to specifications that are
designed to provide reasonable protection against such
interference. However, there is no guarantee that
interference will not occur in a particular installation.
It is therefore recommended to install the equipment and
electric wires keeping proper distances away from stereo
equipment, personal computers, etc.

In places with weak reception, keep distances of 3 m or more to
avoid electromagnetic disturbance of other equipment and use
conduit tubes for power and transmission lines.
▪ 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.
▪ Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings.
▪ Choose a location where the hot/cold air discharged from the unit
or the operation noise, will NOT disturb anyone.
▪ Air flow. Make sure nothing blocks the air flow.
▪ Drainage. Make sure condensation water can be evacuated
properly.
▪ Paper pattern for installation
(accessory). When selecting the installation location, use the
paper pattern. It contains the dimensions of the unit and the
required ceiling opening.
▪ Air flow directions. You can select different air flow directions.
Choose the one best suited for the room. Also make sure the "Air
flow direction" field setting corresponds with the actual situation
(see Field settings).

kit required)
c 3-way air flow (optional blocking pad kit required)
▪ Ceiling insulation. When conditions in the ceiling exceed 30°C
and a relative humidity of 80%, or when fresh air is inducted into
the ceiling, then additional insulation is required (minimum 10 mm
thickness, polyethylene foam).
Do NOT install the unit in the following places:
▪ 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.
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
▪ Spacing. Mind the following requirements:
