Connecting the
flexible duct to the
indoor unit
20
34
Reconnect the flexible duct to the indoor unit by
following the inverse process to that just described.
Warning!
The fast connection can only be mounted in
one position, see Figure 18. It must only be
inserted in its housing in a vertical position.
Exerting a little force, pull up the lever until it
is vertical. Only then is the hose connected
correctly.
Should the indoor and outdoor units be
disconnected for a lengthy period of time,
protect the free end of the flexible duct using
the protective cap (See Accessories and
Fig. 19) supplied to prevent dust and dirt
from entering and fit the protective copper
cover over the valves, Fig. 20. You are
recommended not to leave the duct
disconnected from the indoor unit for more
than 24 hours.
Never operate the indoor appliance without
the outdoor appliance.
