UNIT INSTALLATION
ELECTRICAL CONNECTIONS
ROTATING THE COIL
CAUTION: check that the power supply is disconnected before perform-
ing operations on the unit.
CAUTION: wiring connections installation of the fancoil and relevant
accessories should be performed by a technician who has the necessary
technical and professional expertise to install, modify, extend and main-
tain plants and who is able to check the plants for the purposes of safety
and correct operation.
ATTENTION :In the case of installation in very dusty environments, clean
the dust accumulated in the metal clips inserted into the filter guides
with a vacuum cleaner; perform a visual inspection in order to verify the
contact between clips and filter.
Every anomaly must be communicated to the After-sales Service .(vedi
Capitolo “Disegni” Fig.5).
The fancoil should be installed in such a way as to facilitate routine (filter
cleaning) and special maintenance operations, as well as access to the air
breather valve on the side of the unit frame (connector side).
To install the unit, proceed as follows:
- In the case of floor-mounted units on bases, refer to the instructions sup-
plied with the accessory.
- Use expansion plugs to secure the unit to the wall or ceiling, (not supplied)
(chapter "drawings - fig.2/fig.3")
To install hanging units with the AMPZ brackets, proceed as follows:
- fit the 4 brackets
(chapter "drawings - fig.4")
to the sides of the unit (a);
insert the upper tab in the slot, then secure the lower part to the contact
block by means of the screws supplied;
- secure the flanges (b) to the ceiling by means of expansion plugs (not sup-
plied); for the positions between the flanges and the contact block, see the
dimensional data.
- Make hydraulic connections
(chapter "drawings - fig.6")
Refer to the dimensional data for the position and diameter of the hydraulic
connectors.
Insulate water lines adequately or fit the condensate drainage tray (available
as an accessory) to prevent dripping during cooling applications.
In case of horizontal installation, fit the condensate discharge pipe (supplied
separately) following the indications shown in picture 10. The connection
between pipe and drip tray must be sealed with silicone
(chapter "drawings
- fig.7")
.
The condensate drainage system should be of an adequate size and be posi-
tioned to favour runoff (min. 1% slope). If condensate is discharged into the
sewage system, install a siphon to prevent return of unpleasant odour into
the room.
- Make the electrical connections as shown in the wiring diagrams.
- Remount the front pannel, connect the ambient sensor (if present).
- CAUTION: Keep separate electrical connections from water connections.
Water connections and drain should be on the side opposite of the electrical
connections.
If connection of utilities to the unit requires rotation of the coil, remove the
cover or the front pannel, then proceed as follows
(chapter "drawings -
fig.8")
:
- Remove the condensate tray (a)
- Remove the battery cover (B) by loosening the screws;
- Remove the screws that secure the battery (c) and then pull it out;
- Remove the Sliced veneer seed (d) the right side;
- Rotate the coil (c) and fix it with the screws previously removed;
- Replace the cover (b), securing it with the screws and the plastic caps
(s), supplied together, the holes left by the hydraulic connections;
all the trays are arranged for the condensate discharge on both sides.
- Slide out the electrical connections from the right side, remove the
push and move the cable guide (g) from right to left;
- Transfer the electrical connections on the left side through the cable
guide (g);
- Move the terminal (h) and the jumper of the ground (s) on the left
side.
CAUTION: make sure that electrical power to the machine has been
turned off before making electrical connections.
CAUTION: wiring operations and installation of the fancoil and relative
accessories should be performed by specialised personnel only.
CONNECTION CABLE SPECIFICATIONS
Use H05V-K or N07V-K type with 300/500 V insulation piped or ducted.
All cables must be piped or ducted until they are not placed inside the fan
coil.
The cables coming out of the pipe/duct must not be subjected to stretch or
twist. They must be protected from weather conditions.
Stranded wires may only be used in connection with terminating
sleeves. It must be ensured that all individual wires are correctly insert-
ed in the sleeve.
All wiring diagrams are constantly updated. Please refer to the ones
supplied with the unit.
To protect fan coils against short circuits, always fit the power cable to
the units with 2A 250V (IG) thermo-magnetic all-pole switches with a
minimum contact gap of 3 mm.
We recommend using differential devices suitable for interven-
ing for currents of different type:
sinusoidal AC and pulsating DC currents suddenly applied
or slowly rising.
sinusoidal AC with frequency up to 1000 hz.
The assembling place must be chosen so that the max. and min. room tem-
perature limit is respected 0÷45°C (<85% U.R.).
The control panel may not be fitted on a metal wall unless this is perma-
nently connected to a grounded outlet.
The control panels consist simply of electric circuits connected to the mains
voltage of 230V; all the inputs for the sensors and controls must therefore be
correspondingly insulated for this voltage.
Some control panels are fitted with a room temperature probe and/or a
water temperature probe. In addition, it is possible to connect an external
contact to the internal control board (EX), allowing the remote control of the
fan coil; consult the recapitulatory table and the manuals of the individual
panels to select the most suitable model.
The minimum water temperature probe makes it possible to stop the ven-
tilation automatically if the temperature of the input water to the coil falls
below 39°C.
In installations with a three-way valve, the minimum water temperature
probe must be relocated from its standard mounting in the coil to the deliv-
ery hose upstream of the valve.
When relocating the water temperature probe, the standard probe must be
replaced with an accessory SW3 probe, fitted with a cable of suitable length.
CAUTION: given that it is powered to 230 VAC, the probe has double
insulation.
Multifunction electronic thermostats are supplied ready to operate in stand-
ard configuration, though can be adjusted to the specific operating require-
ments by means of the internal dip-switches.
Customised functions vary between models; for this reason, consult the
relative manuals.
The connections are made by the manufacturer as shown in the picture
(chapter "drawings - fig.7")
.
WARNING: check whether the installation has been carried out cor-
rectly. Follow the checking procedures indicated in the manuals of the
control panels.
