Mounting of built-in control units (Fig.2
p.4-5)
Built-in control units must be mounted on the
opposite side from the fan convector's water
connections.
• After choosing the required functions,
fix the control support bracket that is
included in the delivery, to the edge of the
internal structure with screw and washer.
(Fig.2B)
• Insert the terminal board of the control
unit (MC) into the fan convector's
terminal board of the fan coil (MFC).
Remember to tighten the screws of the
terminal board. (Fig.2C)
• Check that all connections are made
according to the wiring diagrams previous
in this manual.
• Attach the temperature sensor with the
adhesive clips that are included in the
delivery. (Fig.2D-2E)
• Insert the control unit into the support
bracket and mount the plastic cover in the
bottom of the bracket.(Fig.2F-2G)
Water connections
• Always use two spanners when connecting
pipes to the water coil.
• Always install a shut-off valve in the water
circuit.
• It is not possible to change the connection
side on the installation location, as the
fan's direction of rotation is reversed when
the motor group is moved to the opposite
side. The connection side must be given at
the time of ordering.
Important!
• A water trap should be installed on the
condensation water outlet with a fall of at
least 3 cm/metre.
• If the unit is used for cooling the pipes
and valve must be insulated to avoid
condensation.
• During the summer and when the
fan is not used for long periods, it is
recommended that the water supply to
the convector is disconnected to prevent
condensation on the outside of the unit.
• If a supplementary condensation box
is used it must be attached to frame's
connection side and the condensation pipe
must be attached to the condensation box.
• The direction of air flow can be changed
by turning the grille as illustrated below.
