– The flow switch must be tightened on the “T” shaped metallic manifold by the plastic knurled union nut.
Check that the arrow located on the upper side is pointing in the direction of flow. Be sure to fit the O-ring
seal, through the brass manifold and the plastic nut. The O-ring seal is supplied in a plastic cover to protect
the flow switch shaft.
– Connect the flow switch to the other end of the “T” manifold.
– Route the flow switch electrical cable through the hole in the unit structure and run it to the electrical panel
by ascending the upright in the machine interior. Connect the flow to switch terminals 1-14 as indicated on
the electrical drawing.
– The flow switch can be removed by screwing out the plastic knurled union nut. In order to reassemble it,
ensure that the O-ring seal is positioned in proper location (see figure 6).

Direction of flow
Pressure relief valves are fitted on the refrigerant circuit. Some standards specify that these valves must be vented
to the exterior via a vent pipe, the diameter of which must be at least the same as that of the relief valve and
its weight must not affect the valve.
6.7 INDOOR UNIT INSTALLATION
Caution: The relief valve must be directed into a safe zone where
no injuries can be caused to people.
The indoor unit can be installed in a false ceiling with ducting or with direct air flow into the room (models 21-
28), either on the ceiling, or on the floor (models 91 -101).
The minimum clearances required for satisfactory operation of the unit is as follows:
– above or below the unit: enough space for filter extraction;
– suction and supply air side: enough room for duct maintenance.
Give particular care when installing the indoor section (models 21 - 81) and give a incline of at least 10-20 mm
towards the condensation water drainage connection (figure 7).
