Leave a space more than 100 cm at the rear of the appliance and ensure the outdoor air intake not 
be blocked.

A wooden frame as shown in fig.1 is advisable if the appliance is installed through a window. The 
installation bracket as shown in fig.2 should not be welded with the window sash.

The metallic installation bracket should be constructed as fig.4.

The square hole should be smooth enough if the appliance is installed through a wall. A space 
as shown in fig.3 for outdoor air intake should be prepared if the wall is too thick.

All the installation structure should be strong enough.
