Preparation

5.1

Overview: Preparation

This chapter describes what you have to do and know before going
on-site.
It contains information about:

▪ Preparing the installation site

▪ Preparing the refrigerant piping
▪ Preparing the electrical wiring
5.2 Preparing the 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 an installation location with sufficient space for carrying the
unit in and out of the 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).
5.2.1 Installation site requirements of the
indoor unit
INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
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
