Using the side
connections
40
INFO
Usually, you can only use one of the air duct inlets (T1, T3) and air duct outlets (T2, T4) at a
time. If you want to use the sealed duct connections on the longer sides of the unit, you have
to remove the covers and use them to seal the duct connections on the shorter sides, which
are open by default.
CAUTION
Risk of hand injuries!
You may cut yourself on sharp edges when cutting out the metal parts.
• Wear protective gloves!
Please proceed as follows to use the duct connections on the longer sides of the unit:
1. Open the four sealed air duct connections on the longer sides of the unit with side cutters.
Remove any excess metal.

2. If you do not use the air duct connections on the shorter sides, which are open by default,
place an insulation piece in a cap. Then close the corresponding duct connection on the
shorter side of the unit with the insulation cap.

3. Connect the air ducts as described in the section "Air duct connections" on page 38.
