4 - WATER CONNECTIONS
Inlet water : EUROKONUS 3/4
Outlet water : EUROKONUS 3/4
Condensate discharge :Ø14 mm (internal diameter)
For the position of the pipeline and the wall fixings, refer to the
designs shown in the following sections, based on the specific
configuration.
4.1 PIPELINE DIAMETER
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.
4.2 CONNECTIONS
To make the connections:
x position the hydraulic lines ( ref. A)
x tighten the connections using the “spanner and counter
spanner” method ( ref. B)
x check for any leaks of liquid
x coat the connections with insulating material ( ref. C).
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.
4.3 CONDENSATION DISCHARGE
The condensation discharge network must be suitably sized
(minimum inside pipe diameter 14 mm) and the pipeline
positioned so that it keeps a constant inclination, never less
than 1%.
x 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.
x 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
immerged in water to avoid problems of adhesiveness and
counter-pressure that would interfere with the normal outflow.
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.
If there is a height difference that could interfere with the
outflow of the condensation, a pump must be mounted
(provided by the customer)
Insulate the water lines / In the figure are indicated the optional components
M09160D17-02 59

4 - WATER CONNECTIONS
4.3.2 Condensation discharge VERTICAL version4.3.1 Condensation discharge HORIZONTAL version
x Connect to the condensation collection tray discharge
union (fig. 4.3 rif. A) a pipe for the outflow of the liquid (fig.
4.3 rif. B) blocking it adequately.
x Check that the drip-collector extension (fig. 4.3 ref. C) is
present and correctly installed.
To mount the horizontal bowl refer to the instructions in kits.
x check that the "L" pipe and the flexible rubber hose are
correctly connected to the bowl (fig. 4.1 rif. A).
x slide in the side of the machine keeping the pipe in
position up against the front grill.
x fully close the side checking that the pipe remains blocked
in the special grove on the side (fig. 4.2 rif. B).
For the horizontal installation carefully note the following
precautions:
x make sure that the machine is installed perfectly
level or with a slight inclination towards the
condensation discharge;
x insulate carefully the inflow and outflow pipes up to
the machine union to prevent any drops of
condensation outside the same collection bowl;
x insulate the bowl condensation discharge pipe
along all of its length.
4.4 FIXTURE ROTATION
The operations described and the relative images refer to a
machine with fixtures on the left on which the fixtures on the
right side must be rotated.
If there is a machine available with right side fixtures that
require rotation to the left, the sequence of the operations is
the same, only the images are a mirror image.
To connect the motor to the control kit, use the special
cabling optional.
4.4.1 Dismouting panels
x Dismount the upper grill (fig. 4.4 ref. A) unscrewing the
two fixing screws (fig. 4.4 ref. B)
x On the left-hand side lift the cover covering the screw (fig.
4.4 ref. C) and loosen the screw (D) that fixes the left
panel (fig. 4.4 ref. E) , then move it slightly to the left and
lift it up.
x On the opposite side lift the cover covering the screw (fig.
4.4 ref. C) and unscrew it.
x Move the side panel slightly (fig. 4.4 ref. F) to the right and
lift it.
