4. Installation of vent tubes
After drilling the holes, the rubber rings, the plastic pipes and the grids supplied
with the air conditioner need to be fitted through them.
The pipe with a diameter 130mm (hot air discharge) has to be fitted in the right
hole. The length of the pipes should be matches to the thickness of the wall.
Take the rubber ring and insert the nylon cords through the
hooks located on each side of the ring.
Fold the rubber ring in half, grasping the cords with your
free hand.
Insert your arm inside the wall with the ring and push all
the way to the outside. Pull the nylon cords towards you
and with a little manipulation the rubber ring will fit onto
the exterior wall
If you are installing the unit at the ground floor level, you can simply install
both the rubber rings from the outside, by screwing them directly to the
exterior wall with 6mm screws and wall plugs, to prevent the rings removal.
Now take the pipe already fitted with the ring. Let the nylon
cords pass through the pipe length and fit the pipe through the
right hole you drilled previously, until it will fit in the rubber ring.
Fasten the flange with 2*6mm screws and the wall plug and
insert the tightened nylon cords to the dents on the internal
flange.
