To position the external grids, proceed as follows:
- Fit the small eyelet of the spring, with the long stem, on
the cap pin (on both components) (fig. 10/2).
- Fit the two caps (with spring), from the front part of the
external grid, on the two housings, pulling until a click is heard
(fig. 10/3) and attach the two chains to the large eyelet
of the spring.
- Using one hand, grip the two chains connected to the grid.
- Bend the external grids back, gripping these with your
free hand where the bend is and introducing your
fingers inside the single fins (fig. 10/4).
Introduce your arm into the pipe until the grid protrudes
completely outwards.
- Allow the grid to reopen, being careful to keep your
fingers inside the fins.
- Turn the grid until the fins are fully horizontal and tilted
towards the outside.
- Pull the chain, tensioning the spring, and fasten the ring
of the chain onto the pin of the inner washer (fig. 11).
- Using a pair of nippers, cut the excess chain links (fig.
12).
Warning: If the external grating is accessible, to
prevent the hazards resulting from its possible
removal (insertion of the hands into the pipes and
touching moving or powered parts) it is absolutely
essential to fasten it to the wall with 4 anchor bolts
with a diameter of 6 mm.
2.3.4 The air conditioner is equipped with a power supply cable
Power supply and plug.
Connection If it is installed near an outlet, you need only plug it in.
In this case, it is important to make sure the outlet to which
you are plugged in is effectively grounded and connected
to the mains by wiring of adequate size (minimum 1.5
sq.mm. cross section). To make an electrical connection
with the shielded cable (recommended for installations high on
the wall) proceed as follows:
Install a shunt box in the wall in the position shown on the
installation template (fig. 6), where you should provide a power
cable with a cross-section (two poles plus ground wire) of 2,5
sq.mm.
Warning: The external power line should be provided with
an overload circuit breaker with suitable capacity for the
rating of the machine.
Make all connections in compliance with the laws in effect.
Close the shunt box with its cover after drilling a hole in it for
passage of the cable.
Alternatively, you can use a cable in the wall in the position shown
on the template, for making the connection. In this case,
remove the casing (as described in paragraph 2.4.2) and
connect the cable to the power terminal board.
Caution: these operations should be performed with the
machine already positioned on the bracket. Read the
instructions carefully before completely the electric
connection.
