NB: the nominal diameter, unless otherwise indicated,
always refers to the internal diameter.
To avoid the formation of surface condensation, it is
always recommended to install electric valve kits, except
in the case where an electrical control (eg electrothermal
head) is provided upstream of the appliance. The choice
and sizing of the hydraulic lines must be made by an
expert who must operate according to the rules of good
technique and the laws in force, taking into account that
undersized pipes cause a malfunction.
To make the connections:
- position the hydraulic lines
- tighten the connections using the “spanner and
counter spanner” method
- check for any leaks of liquid
- coat the connections with insulating material.
The hydraulic lines and joints must be thermally
insulated.
Avoid partially insulating the pipes.
Do not over-tighten to avoid damaging the insulation.
Use hemp and green paste to seal the threaded
connections; the use of Teflon is advised when there is
anti-freeze in the hydraulic circuit.

INSTALLATION
Condensation discharge
The condensation discharge network must be suitably
sized and the pipeline positioned so that it keeps a
constant inclination, never less than 1%. In the vertical
installation, the discharge pipe is connected directly to
the discharge tray, positioned at the bottom of the side
shoulder underneath the hydraulic fixtures. In a horizontal
installation the discharge tube is connected to the one
already present on the machine.
- If possible, make the condensation liquid flow directly
in a gutter or a “rainwater” discharge.
- When discharging directly into the main drains, it is
advisable to make a siphon to prevent bad smells
returning up the pipe towards the room. The curve
of the siphon must be lower than the condensation
collection bowl.
- If the condensation needs to be discharged into a
container, it must be open to the atmosphere and
the tube must not be immersed in water to avoid
problems of adhesiveness and counter-pressure that
would interfere with the normal outflow.
- If there is a height difference that could interfere with
the outflow of the condensation, a pump must be
mounted:
- in a vertical installation mount the pump under the
lateral drainage tray;
- in a horizontal installation the pump position must be
decided according to the specific requirements.
Such pumps are commonly found in commerce.
However, on completion of the installation it is advisable
to check the correct outflow of the condensation liquid by
slowly pouring about ½ l of water into the collection tray in
about 5-10 minutes.
Connect to the condensation collection tray discharge
union a pipe for the outflow of the liquid blocking it
adequately. Check that the drip-collector extension is
present and correctly installed.

INSTALLATION
Mounting the condensation discharge pipe in the horizontal version
Connection pipes - Ø14 mm Discharge
To mount the horizontal bowl on the FWXM-series refer to
the instructions in kits EKM(10/15/20)COH.
- check that the "L" pipe and the flexible rubber hose
are correctly connected to the bowl.
- slide in the side of the machine keeping the pipe in
position up against the front grill.
- fully close the side checking that the pipe remains
blocked in the special grove on the side.
N.B. for the horizontal installation carefully note the
following precautions:
- make sure that the machine is installed perfectly level
or with a slight inclination towards the condensation
discharge;
- insulate carefully the inflow and outflow pipes up to the
machine union to prevent any drops of condensation
outside the same collection bowl;
- insulate the bowl condensation discharge pipe along
all of its length.
Breather
Filling the system
Evacuating air while filling the system
When starting up the system, make sure that the hydraulic
unit lockshield is open. If there is no electric power and the
thermo-valve has already been powered use the special
cap to press the valve stopper to open it.
- Open all the shut off valves (manual or automatic);
- Start the filling by slowly opening the system water
filling tap;
- For the unit installed in a vertical position, take a
screwdriver and opne the highest breather of the heat
exchanger; for appliances installed in a horizontal
position, open the highest positioned breather.
- When water starts coming out of the breather valves
of the appliance, close them and continue filling until
reaching the nominal value for the system.
Check the hydraulic seal of the gaskets.
It is advisable to repeat these operations after the appliance
has been running for a few hours and periodically check
the pressure of the system.

pump convector in perfect working condition, safe and
reliable over the years. This can be done every six months
for some interventions and annually for others, by the
Technical Service Assistance, technically authorised and
prepared, using always original spare parts.
Before every cleaning and maintenance intervention,
disconnect the appliance from the mains by switching
off the master switch.
Wait until the parts have cooled down to avoid the risk
of burns.

TROUBLESHOOTING
Troubleshooting
Table of anomalies and remedies
In case of water leaks or anomalous functioning
immediately cut off the power supply and close the
water taps.
Should one of the following anomalies occur, contact
an authorised service centre or an authorised qualified
person, but do not intervene personally.
- The ventilation does not activate even if there is hot or
cold water in the hydraulic circuit.
- The appliance leaks water during the heating function.
- The appliance leaks water only during the cooling
function.
- The appliance makes an excessive noise.
- There are formations of dew on the front panel.
The interventions must be carried out by a qualified installer
or by a specialised service centre.
Effect Cause Remedy
A delayed activation of the ventilation
respect to the new temperature or
function settings.
The circuit valve needs some time to
open and as a result the hot or cold
water takes time to circulate in the
appliance.
Wait for 2 or 3 minutes to open the
circuit valve.
The appliance does not activate the
ventilation. No hot or cold water in the system. Check that the water boiler or cooler are functioning correctly.
The ventilation does not activate even if
there is hot or cold water in the hydraulic
circuit.
The hydraulic valve remains closed.
Dismount the valve body and check if
the water circulation is restored.
Check the working efficiency of the
valve by powering it separately with
230V. If it activates the problem could
be the electronic control.
The fan motor is blocked or burnt out. Check the windings of the motor and
the free rotation of the fan.
The micro-switch that stops the
ventilation when the filter grill is opened
does not close correctly.
Check that by closing the grill the micro-
switch contact is activated.
The electrical connections are not
correct. Check the electrical connections.
The appliance leaks water during the
heating function.
Leaks in the hydraulic connections of
the system.
Check the leak and fully tighten the
connections.
Leaks in the valve unit. Check the state of the gaskets.
There are formations of dew on the
front panel. Thermal insulation detached.
Check the correct positioning of the
thermo-acoustic insulation paying
attention to that in the front above the
finned heat exchanger.
There are drops of water on the air
outlet grill.
In situations of high humidity (>60%)
condensation could form, especially at
the minimum ventilation speeds.
As soon as the humidity starts falling
the phenomenon disappears. In any
case the presence of a few drops of
water in the appliance does not indicate
a malfunction.

INSTALLATION
Effect Cause Remedy
The appliance leaks water only during
the cooling function.
The condensation bowl is blocked. Slowly pour a bottle of water in the
low part of the battery to check the
drainage; if necessary, clean the bowl
and/or increase the inclination of the
drainage pipe.
The condensation discharge does not
need an inclination for correct drainage.
The connection pipes and the valve unit
are not insulated well. Check the insulation of the pipes.
The appliance makes a strange noise.
The fan touches the structure. Check the clogging of filters and clean
them if necessary
The fan is unbalanced.
The unbalancing causes excessive
vibrations of the machine; replace the
fan.
Check the clogging of filters and clean
them if necessary Clean the filters
