5.1 Important

Danger

• Make sure that the Mains supply to the unit is disconnected before performing any maintenance or

electrical work!

• All electrical connections must be carried out by an authorized installer and in accordance with

local rules and regulations.

Warning

• Although the Mains supply to the unit has been disconnected there is still risk for injury due to rotating

parts that have not come to a complete standstill.

• Beware of sharp edges during mounting and maintenance. Use protective clothing.

Even if the required maintenance, such as change of filters, is carried out dust and grease may slowly
build up inside the fans. This will reduce the efficiency. The fan motor can overheat if a thick layer of dust
prevents the air from entering the motor to cool down the stator structure.
