10.1 - Safety instructions
All maintenance operations must be carried out strictly observing the European and National accident prevention regulations.
We refer especially to the accident prevention regulations concerning electrical systems, refrigerators, and manufacturing resources.
Maintenance may be done to air conditioning equipment only by authorized and qualied technicians.
To keep all warranties valid the maintenance must adhere to the manufacturer’s regulations.
The work should be done in the system only when it is at standstill. Do this by switching o󰀨 the air conditioner at the
controller and the main switch. Post a warning sign saying: ”DO NOT SWITCH ON.”
Electrical components of device have to be switched o󰀨 and be checked that they are not under voltage.
Ignoring the safety instructions can be dangerous to persons as well as to the environment.
Soiled parts always cause a loss of performance and for switch or control devices can lead to the break- down of a plant.
