CHAP 2.7 INSTRUCTIONS TO INSTALL THE FRESH AIR KIT KR100
The fresh air kit allows the outside air to enter into the room where the air
conditioner is located.
This device guarantees that about 90 m3/h are brought into the room,
resulting in a very good change of air.
Follow carefully these instructions and you will be able to install perfectly the
appliance.
NOTICE

The kit has to be mounted to the wall before the air conditioner
•
It have to be installed on an outside wall, preferably not on the walls looking
onto a road or places where there are polluting substances
•
The minimum height from the ground must be at least 6 metres for walls
looking onto high traffic-congested roads and 3 metres in all the other cases.
•
Check that nothing could obstruct the airflow at the device inlet (trees with
leafs, curtains, etc..)
•
To improve the air downflow from the room it is recommended to install a
plenum lock-gate with approx. dimensions 150x150 mm.
INSTALLATION
After having determined the position of the indoor unit fixing bracket, trace the centre of
the hole following the instructions of picture 1.
•
Drill the wall using a suitable drill equipped with core bit with a diameter of at least
132 mm. The hole has to be perfectly horizontal, or at the most having a slight
inclination toward outside.
•
Put the 130-mm. pipe into the hole, after you cut it according to the wall thickness.
