7.6.3 Drilling a Hole in the Wall for Drainage and Inter-Unit Connections
•
To make the connections between the indoor and outdoor units, a 70 mm hole should be
drilled for the refrigerant lines, drainage hose and electrical cable passage, through the wall,
as shown in Fig. 7-6.
•
Make sure to drill outwards and downwards, so that the opening in the outside wall is at
least 10 mm lower than the opening on the inside.
•
Route the drainage hose at the bottom of the hole.
•
Fill in the remaining wall hole gap with an appropriate sealant.

7.7 Air Duct Installation
•
The air ducts should be constructed of 0.7-0.8 mm galvanized metal sheet.
•
To obtain optimal results, dust cross sections, connections, elbows and branches must be
properly designed. We highly recommend seeking for expert advice on this matter.
•
Air ducts should be properly insulated (preferably on the inside) with 50 mm thick
fiberglass insulation having density of at least 24 Kg/m
