3.1.9 Models with right-hand hydraulic
connections
The fancoils in the AirLeaf range are designed with:
• hydraulic coil connections on the left side of the unit
• electrical connections on the right side of the unit
 Should it be necessary to invert the position of the coil's
hydraulic connections from the left (default) side to the
right side, the hydraulic Hydraulic connection reversal
kit must be used to make the electrical connections to
the fan motor and the grid safety microswitch.
Right-hand side hydraulic connection
reversalkit
 For the hydraulic Hydraulic connection reversal kit
please refer to the "Coding accessories" p.7section.
The hydraulic connection reversal kit consists of:
• a cable with male/female connectors which is con-
nected to the fan motor on the right-hand side and to
the quick connector (MOTOR) on the electrical board
on the left-hand side.
To make the connections:
– connect the cable to the fan motor
– pass the cable through the hole in the back of the
unit
– connect the cable to the MOTOR quick connector on
the printed circuit board
 Pass the cables to the back of the unit.

4.2 Installation
4.2.1 Description
the wall-mounted remote control is an electronic LED ther-
mostat with a touch interface, with the possibility of control
over multiple appliances equipped with the same electron-
ic board. It is equipped with a temperature and humidity
probe.
 The control can control up to a maximum of 16 units.
 The temperature probe can be remoted in one of the
connected device.
4.2.2 Mounting
 The control panel for wall control is to be installed in-
side a 503 electrical box.
 A wall must be prepared to accommodate the 503 elec-
trical box before installing the wall control. The wall-mounted remote control must be installed:
• on internal walls

• away from doors or windows
• away from heat sources (heaters, convectors, stoves,
direct sunlight)
 The wall control is provided inside the package already
assembled.
