Installation Of The Pipes; Fitting The Gratings - MAXA 2600 W STD Manual Usuario Y Instalador

2.5 INSTALLATION OF THE PIPES

- After drilling the holes, the plastic pipes supplied with the air conditioner need to be fitted through them.
- The pipe with a diameter of 160mm (fresh air intake) has to be fitted in the right hole.
The length of the pipes should be same the depth of the wall plus 10 mm. Use a normal hacksaw to cut the supplied
pipes to the correct length. Remember that the modification must to have the same inclination of the holes (minimum
3 degrees).
- The tube diameter is nearly the same as that carried out using the 162 mm nominal diameter core drill therefore
you may need to slightly force the introduction of the pipe using, in difficult cases, a normal rubber hammer and a
small piece of timber to gently tap the tube into the hole.
- Please use the same instructions to fit the left hand tube (AIR discharge pipe) using the supplied pipe with a
diameter of 150mm. The tube diameter is slightly smaller than that carried out using the 162 mm nominal diameter
core drill.
- Please centre the pipe into the hole in
the wall and insulate and seal their perimeters to prevent air and humidity infiltration using polyurethane foam and
using plaster as finishing on the inside wall.

2.6 FITTING THE GRATINGS

To fit the external two gratings please proceed as follows: familiarise yourself with the fitting of the grating to the tube,
before installation.
Insert the cords through the centre of the grating.
One grating fits on the outside of the tube and the other fits inside. The air intake is the bigger hole and the grating
therefore fits on the outside of the air intake tube.
Insert the supplied cord into the hole. Fold the outer grating in half grasping the cord with your free hand.
Insert your arm inside the pipe with the grating and push all the way to the outside.
Let the grating unfold and pull the cord toward you. One grating fits on the outside of the tube and the other fits
inside. With a little patience and manipulation the 2 gratings will fit the end of the tubes. Grasping the cord, insert
your fingers between the fins and pull the grating toward you until the same is properly slipped in the pipe, keeping
the fins in vertical position. If the external grating is accessible to prevent its removal, it is recommended to fasten it
to the wall with wall plugs and screws with a diameter of 6 mm. Tighten the cord and fasten it to the dent on the
internal flanges.
