10.4 FINAL INSPECTION
Check that:
• The impeller is mounted for the correct direction of rotation.
• All screws and nuts have been tightened to the corrrect torque values.
• No foreign objects have been left in the casing or in the ducting.
• The mechanical opening of the hatch works.
10.5 MECHANICAL OPENING OF THE DOOR
The mechanical opening of the hatch is intended for emergency situations where the door has to be opened when
the electrical supply has been disrupted/turned off.
The door can be opened mechanically by pulling the wires under the hatch. There are two wires, and they are
located on both sides of the linear motors. Pulling on the wire requires some force, so you must use an aid, such as
a steel rod, formed into a hook (see picture for example).
After mechanically opening the lid, re-attach the linear motor shafts to the mounting lugs and make sure that the
cover seals are intact.
