Electrical Connection - Novy 906.270 Instructions D'installation

INSTALLATION
Depending on the type of electrical non-return valve, the connection pieces are a circular channel with a diameter of 125
or 150 mm. The connection piece must placed in the circular channel.
• Position the device and the electrical connection in such a way that they can be accessed in case of servicing.
• Ensure the channel where the electrical non-return valve is to be placed is sufficiently supported.
• For an airtight connection, the transition between the non-return valve and the circular channel must be
sealed with tape or a hose clip.
20 mm
• Do not place screws in the plastic housing, or 20 mm on either side of it (this may obstruct the non-return
valve during operation).
• Outside this zone, the length of the screw must not exceed 20 mm.
• Never operate the non-return valve manually (this risks causing damage to the motor).
• The metal connectors must not be removed from the plastic housing.
• The non-return valve is completely open or completely closed; locking the non-return valve in an intermediate
position (through mechanical means) is forbidden.
• The non-return valve must not be subjected to prolonged activity at high humidity, and never more than 90%
RH.

ELECTRICAL CONNECTION

• Connect the connection cable to the 230 VAC power supply.
• In the event of servicing being carried out on the non-return valve, the power supply must first be disconnec-
ted.
