General precautions on installation
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.
The space around the unit is adequate for maintenance and
servicing (refer to
"7.2. Service space" on page
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.
All piping lengths and distances have been taken into
consideration (refer to
"9.5. System piping (length) limitations"
on page
13).
Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings.
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, refer to
"18. Caution for refrigerant leaks" on page
CAUTION
Excessive refrigerant concentrations in a closed room can
lead to oxygen deficiency.
