NSTALLATION OF THE UNIT
6.1. Selecting an installation location
General precautions on installation location
Select an installation site that meets the following requirements:
■
The foundation must be strong enough to support the weight of
the unit. The floor is flat to prevent vibrations and noise
generation and to have sufficient stability.
This is especially of importance when the optional domestic hot
water tank is installed on top of the unit.
■
The space around the unit is adequate for maintenance and
servicing (refer to
"Service space of the unit" on page 12 ).
■
The space around the unit allows for sufficient air circulation.
■
There is no danger of fire due to leakage of inflammable gas.
■
The equipment is not intended for use in a potentially explosive
atmosphere.
■
Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone, and the location
is selected according the applicable legislation.
If the sound is measured under actual installation conditions, the
measured value will be higher than the sound pressure level
mentioned in
"12. Unit specifications" on page 44 due to
environmental noise and sound reflections.
Choose the installation location carefully and do not install in a
sound sensitive environment (e.g. living room, bedroom, …)
■
All piping lengths and distances have been taken into
consideration (For requirements of piping length for the
refrigerant piping, refer to the outdoor unit installation manual).
■
Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings.
■
The installation location is frost-free.
■
Be sure that sufficient precautions are taken, in accordance with
the applicable legislation, in case of refrigerant leakage.
■
When installing the unit in a small room, take measures in order
to keep the refrigerant concentration from exceeding allowable
safety limits in the event of a refrigerant leak.
■
Do not climb, sit or stand on top of the unit.
■
Do not place any objects or equipment on top of the unit (top
plate).
■
Do not install the unit in places often used as workplace. In case
of construction works, where a lot of dust is created, the unit
must be covered.
■
Do not install the unit in places with high humidity (e.g.
bathroom) (max humidity (RH)=85%).

WARNING
Be sure to provide for adequate measures in order to
prevent that the unit be used as a shelter by small animals.
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean and clear.
Requirement Value
Maximum allowable distance between the domestic
hot water tank and the indoor unit (only for
installations with domestic hot water tank).
10 m
If the installation is equipped with a domestic hot water
tank (optional), please refer to the domestic hot water tank
installation manual.
WARNING
Excessive refrigerant concentrations in a closed room can
lead to oxygen deficiency.
