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 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
outdoor unit
INFORMATION
Also read the following requirements:
▪ General installation site requirements. See the
"General safety precautions" chapter.
▪ Service space requirements. See the "Technical data"
chapter.
▪ Refrigerant

requirements
(length,
height
difference). See further in this "Preparation" chapter.
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
and
light
industrial
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.
▪ Select a place where rain can be avoided as much as possible.
▪ 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.
▪ 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 play).
Do NOT install the unit in the following places:
▪ 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 might be higher than the sound
pressure level mentioned in Sound spectrum in the data book due
to environmental noise and sound reflections.
▪ 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
Seaside installation.
Make sure the outdoor unit is NOT directly
exposed to sea winds. This is to prevent corrosion caused by high
levels of salt in the air, which might shorten the life of the unit.
Install the outdoor unit away from direct sea winds.
Example:
Behind the building.
