Aeraulic connections
The machine is equipped with plastic nozzles with gaskets, which protrude about 4 cm and
which make it possible the connection with flexible or rigid ducts, provided that they are
equipped with gaskets to avoid air leaks and unpleasant noise. Spigot diameters are as follows:
supply and recirculation
Ø 200
fresh air intake and air exhaust
Ø 200
stale air from bathroom/kitchen
Ø 160
PLEASE NOTE: the real diameter of the air spigots is approximately 1-2 mm less than the
nominal diameter.
ELECTRICAL CONNECTIONS
CONDUCTOR SIZE
The electric power supply line and the isolating devices must be decided by qualified staff
responsible for the electrical design. In any case, the cable must have a minimum cross-section
of 3x1.5 mm², F + N + PE.
The following diagram shows the terminals which are available for connections:
-
the machine must be connected to an electric power supply;
-
a 4-wire connection provides the control panel with both the 24VDC power supply and
the serial communication. This connection cable must have a minimum cross-section of 0.5
mm² and must be shielded.
