INSTALLATION
Unit placement
Installation procedure
Daikin FWXT convectors have to be installed only in high
wall position, above 2 meters.
Avoid installing the unit near:
- areas exposed to direct sunlight;
- heat sources;
- in damp areas and areas in which the unit can come into
contact with water;
- in environments with oil mists;
- in environments subject to high frequencies.
Make sure that:
- the wall on which you intend to install the unit is strong
enough to support the weight;
- the wall surface is not crossed by pipelines or power lines;
- the wall is perfectly flat;
- there are no obstructions nearby that could compromise
the inlet and outlet airflow;
- the wall on which you are installing the unit is (if possible)
an external perimeter wall, in order to allow condensate
drain outside the premises;
- air flow is not directed towards by-standers.
The assembly steps described below and their drawings
refer to a version of the machine with connections on the
right side.
For ideal installation and performance levels, carefully
follow the instructions in the manual.
Failure to do so may cause system malfunctions and
automatically voids the warranty, and relieves the
manufacturer of any harm caused to persons, animals
or property.

Wall installation
• For smooth installation, especially if you want to
set-up the system before you install the device, we
recommend installing a wall recess, as shown in the
figure;
• If you do not complete installation of the device
when installing the wall recess, leave the water and
condensate drain pipes hanging loose, so that you
can later make the connections without joints;
• When you finally install the device, it will be possible
to connect the convector with a 90° fitting and socket
with eurokonus connection;
• another option if you can comfortably bend the
pipeline (which will depend on the depth of the
installed recess) is to install the eurokonus connection
inside the pipeline;
• pay attention to the tilt angle of the condensate drain
pipe, which must rest be laid on the lowermost part
of the recess so that the pipe’s height never exceeds
the height of the cooler-radiator drain connection;
• for the installation heights, refer to the installation
template supplied with the device and which is shown
in the following pages.

over-tighten the screws so that you can adjust them
with a spirit level.
3. Firmly fasten the brackets by tightening the four
screws.
4. Check stability by moving the brackets to the right
and left, up and down.
5. Assemble the unit, making sure it fastens properly
onto the brackets and that it is stable.

Hydraulic connections
The engineer is responsible for choosing the right water
lines and their size, in accordance with good installation
practices and the applicable laws, keeping in mind that
under-sized pipelines lead to poor system operation.
To make the connections:
- position the water lines
- tighten the connections using the "wrench against
wrench" method
- check for any fluid loss
- apply a lining to the connections (use proper insulating
material)
The hydraulic lines and fittings must be thermally insulated.
Avoid partial insulation of the pipes.
Avoid over-tightening the pipes to avoid damage to the
insulation.
To ensure water tightness of the threaded connections,
use hemp and green paste; the use of teflon tape is
recommended if you have poured anti-freeze liquid in the
water circuit.
Carefully check that the insulation is tight, in order to
prevent the formation and dripping of condensate.
Note: Always provide an electrically controlled valve
on the machine or upstream that interrupts the water
flow when the setpoint is reached.

Condensate drain
The condensate drain network must be sized appropriately
(minimum inner pipe diameter: 14 mm) and the pipeline
positioned so that it maintains a consistent slope along the
line (never less than 1%). The drain pipe connects directly
to the drain pan installed at the bottom on the side panel
under the hydraulic connections.
- If possible, make the condensate liquid flow directly
onto a gutter or into a "clean water" drain.
- If the liquid is discharged into a sewer, we recommend
that you install a trap-vent to prevent bad odours from
rising back up into the building. The curve of the trap
must be lower than the condensate tray.
- If you need to drain the condensate into a container, it
must remain open and the pipe must not be immersed
in water to prevent adhesion and back-pressure that
would obstruct free flow.
- If the drain pipe has to overcome a gap in height
due to its particular installation which would obstruct
condensate flow, remember to install a pump:
These pumps are commonly available on the market.
However, it is advisable that after installing the pump you
check proper flow of the condensate liquid, pouring it in
very slowly (about 1/2 l of water in about 5-10 minutes)
into the drain pan.
Connect the drain connection of the drain pan that collects
the condensate fluid to a hose and tighten it properly.
Make sure the drip-guard extension is present and that it
has been properly installed.

Evacuating the air when filling the system
When starting the system, make sure that the
lock-shield on the hydraulic unit is open. If there
is a power black-out and the thermal valve
is already running, use its cap to press the valve shutter
and open it.
- Open all the system’s shut-off valves (whether manual
or automatic);
- Start filling the system by slowly opening the water
tap;
- With the aid of a screwdriver, open the vent on the
uppermost coil connection (see figure below);
- When water begins to leak out of the breather valves,
close them and continue to fill the system (as per the
rated specifications).
Check the tightness of the gaskets.
We recommend that you repeat this operation when the
device has been running for a few hours and that you
regularly check the system’s pressure.
Pay attention to the tilt of the condensate drain pipe when
it channels condensate outside the premises as shown in
the figure.

2.11 Wiring
• Access the electrical parts as described in paragraph
2.4.
• An on/off switch with delayed fuse or an automatic
circuit breaker (2A) must be installed to supply power
to the system.
• Because the wiring features a suppression filter, as
required by the applicable laws and standards, which
naturally induces leakage current to the ground, it
is best to install selective differential circuit breakers
upstream of the system.
• For safety reasons, the on/off switch referred to
above should be installed near the device or at any
rate in open view.
• The power cables must be equipped with copper
conductors having the following unitary sections (the
values indicated refer to a maximum line length of
15m). The cables must be appropriate for the type
of installation, in accordance with the applicable CEI
standards.
