Fan Coil of SEC type
1.7
Hydraulic connections
Maximum working pressure: 8 bar.
Always use two spanners to connect the heat exchanger to the pipes.
Always fit a gate valve in the water circuit.
To reverse the connections side, proceed as follows:
1 - Undo the four screws (two per side) fixing the coil to the frame and remove the coil.
2 - Undo the two screws fixing the baffle to the coil and remove it together with the lagging covering the
coil. Reposition it on top of the coil.
3 - Disconnect the wires (taking note of the colour). Undo the screws fixing the terminal board and remove
it.
4 - Remove the pre-cut shape from the frame.
5 - Remount the baffle at thebottom and replace the coil, fixing it with the four screws.
6 - Fix the control unit and terminal board on the opposite side to the connections.
7 - Reconnect the electrical wires, following the notes made previously and referring to the electrical wiring
diagram.
IMPORTANT!
You are recommended to fit a siphon on the condensate drain. Install a
condensate drain pipe with a slope of at least 3 cm/metre.
If a second heat exchanger coil is fitted, to change the connections side,
proceed as described previously.
If the unit is fitted with a valve, connect the connection pipes to the valve.
If the unit is used for cooling, insulate the pipes and valve to avoid drops
of condensate forming.
During the summer and when the fan is inactive for long periods, you are
recommended to shut off the water supply to the coil to avoid
condensation forming on the outside of the unit.
If a supplementary condensate drain pan is used, this should be fixed to
the connections side of the frame and the condensate drain pipe should be
fastened to the latter.
In the MV, MVB and MO versions, the air flow can be reversed by
rotating the grill as illustrated.
