Ventilator mounting
Read the users manual before installing the unit
Do not block the air duct of the installed unit with dust accumulating materials, such as
curtains, cloth shutters, etc. As it prevents air circulation in the room.
1. Prepare a round core hole in the outer wall
Make one or two holes in the exterior wall according to the configuration of the ventilation system. For
efficient ventilation, the locations of ventilation systems must be as far apart as possible. When preparing
the holes, it is recommended to also prepare places for laying the electrical cable and other necessary
cables in the wall. The size of the hole and the minimum distance to the surface (eg wall, ceiling or window)
and the minimum distance between the devices are shown below.
2. Measure the air ducts of the required length
Measure the wall thickness B
The required air tube length is calculated as L = B + A.
A means the part of the air tube from the outside that is required for installation of an external ventilation
cover. Distance A is given in the instructions for installing the external ventilation cover. Cut the air tube to
length L.
