To install the damper

Install the damper on the other side of the unit.
▪ Carefully guide the wires from the outside to the inside
through the small hole in the unit's metal plate. Take care
not to damage the connector and the earth wire connection.
▪ Position the damper onto the unit. Take care not to pinch
and damage the wires between the damper and the unit.
▪ Pull the wires through until the foam insulation fits properly in
the small hole in the unit's metal plate. This makes the
connection airtight.
