Electrical operations:
Electric operations (installation, repair, modification, maintenance, adjustment)
have to be fulfilled by trained and authorised personnel only.
When dealing with electrical issues, the specific rules of the country within which
the equipment is installed must be followed, in addition to the instructions within
this manual.
When working on the equipment or parts of it, the system has to be de-
energised (by master switch, circuit breaker or separate cut-out) and made safe
against restart of the system. Do not reconnect the system to the electric circuit
until all work is done and all connections are tested.
If handled unsafely or unprofessionally, severe electric shocks can occur. Con-
sider the wiring diagram and follow the instructions of this manual very carefully
whilst working on electrical parts. Wrong connections or incorrect grounding
may lead to severe injuries and mortal danger.
Ground the system according to the particular requirements of the country within
which the equipment is installed.
Connect all the wires properly and durably. Loose cables may lead to overheat-
ing or fire
.
Installation site:
Ensure that the ceiling or the wall is solid enough to carry the weight of the sys-
tem which will be mounted on it. Pay attention to the installation of the outdoor
unit: operating noise and air flow should not bother neighbours.
Make sure that appropriate measures are taken against noise emissions, espe-
cially when the system is to be installed close to sensitive facilities (such as hos-
pitals).
Insulate all tube connections professionally to avoid formation of water conden-
sation and water damage to the rooms.
The outdoor unit must be fixed to a flat, stable location. Thereby pay attention
that in that location there is no snow, foliage or dirt accumulating. Take care of
further requirements to prevent the system from damage by earthquakes, hurri-
canes or high winds.
Do not touch movable parts and keep free from clothing. Do not touch any part
of the system without wearing suitable personnel protective equipment and
clothing in order to avoid injury from: the compressor (hot surface), the refriger-
ant condenser (hot surface, sharp fins) and the refrigeration tubes (hot and cold
surfaces, sharp spots).
Suitable personnel protective equipment is at a minimum:
1. Goggles
2. Gloves
3. Shoes
4. Overalls
