All maintenance work has to be carried out under strict compliance with the country-specific accident pre-
vention regulations. In particular we refer to the accident prevention regulations for electrical installations,
refrigerating machines and equipment. Non-compliance with the safety instructions can endanger people
and the environment.
Maintenance work must only be carried out on the units by authorized and qualified specialist staff.
Procedure instructions
• carry out work on the system only when it is shut down.
• switch off the chiller at the controller and at the master switch.
• display a „DO NOT SWITCH ON“ warning sign.
