Rapid couplings in model F300
In this model, the connections of the internal
unit must be disconnected as follows:
1) Unplug the appliance from the main.
2) Remove the filters on the side.
3) Remove the rear door in the back panel
by undoing the two screws.
4) Remove the metal "U"-stays fixing the
pipes to the appliance (2).
5) Use a number 24 spanner to undue the
rotating union on the coupling. At the
same time, use a number 21 spanner to
hold the end of the flexible pipe. Repeat
for the second union using a number 24
and a number 19 spanner
6) Disconnect the condensate pipe from the
pipe fitting.
7) Remove the electrical connection block.
Avoid tight curves in the connection
sheath

Reconnecting the sheath in models F400 and F300
To reconnect the ends of the connecting
sheath to the internal unit, repeat operations
1, 2, 3, 4, 5, 6 and 7 in reverse order, observing
the following precautions:
• Before passing the sheath through the
hole in the wall, protect the threaded
ends of the rapid couplings with insulating
tape or similar.
• Fit the top two refrigerant couplings to the
bottom two and hand tighten them for
several turns. Check they fit well before
tightening with the spanners used previou-
sly
• After connecting the two refrigerant cou-
plings, fix the stays.
• Check the seal of the refrigerant connec-
tions by covering the joins with a little
soapy water. No soap bubbles should
form.
Attention
We recommend that disconnection and con-
nection of the rapid couplings be carried out
by qualified personnel.
