Central vacuum systems
Remove the protection cap and the cover of the
backup box
Connect the inlet valves to the power mains
The two incoming electric cables must be connected
in parallel to the two outgoing cables with a binding
screw. Then connect the binding screw to the inlet
valve.
Resistances
If you use the sequential starting device please
control if there is a resistance (code IS106) 4700
on every single inlet valve. The resistances can be
installed later and welded on one of each outgoing
cable of the control operation panel which is on the
inlet valve. Protect the resistance with a thermoproof
covering.
Install the inlet valves
•
Put some soap on the corresponding tightness
O.R. for an easier insertion of the inlet valve into
the backup box.
Installation and connection
of the inlet valves
INSTALLATION AND CONNECTION OF THE INLET VALVES
AND OF THE CENTRAL VACUUM CLEANER
•
Pre-screw carefully the screws of the inlet valve
with a screwier, so that the socket is not deformed.
•
Adjust the position of the inlet valve with a
screwdriver, using washers if necessary.
Please notice: if the screws are not properly
screwed this may compromise the perfect tightness
of the inlet valve and as a consequence the
performance of the system.
•
Use the proper extensions if the backup box is
too embedded with respect to the plaster’s surface
(for instance because of the panelling of the
walls). If necessary, it is possible to glue several
extensions.
