• The appliance must be connected to a mains circuit breaker in the fixed installation.
• Switch power off (all-pole circuit breaker) before servicing or maintenance, and make sure the impeller
has come to standstill.
• Make sure protection grid has been installed (EN ISO 13857), no moving parts shall be accessible after
installation.

Warning
• The fans can have sharp edges and corners which may cause injuries. Be careful when opening the fans,
the motor assembled on the motor bracket is relatively heavy.
Caution
