3AREAULICI CONNECTIONS
3.1.1 GUIDELINES AREAULICI
The unit is provided on three sides (left, right and rear) of two spigots diameter 160mm, for external and eject hot and humid air air
inlet;
For the correct connection of the air ducts, refer to the following diagram and the places adhesives unit.
CONFIGURATION VERSION
The minimum diameter of the pipe and fittings must
be 160 mm (models 7/10) and 200mm (15 models).
The material constituting the pipe must be
thermoplastic or otherwise another material resistant
to air saturated with moisture.
The eventual rectangular ducts or square must take
into account a minimum diameter equal to 0.03 m2.
(7/10 models) and 0.05M2(15 models)
The maximum linear path of inlet pipes and exhaust
air for the condenser must not exceed 8 meters, path
linear;
It must take into account that:
- Each sharp bend equals 3,3 linear meters of
pipe.
- Each wide-radius turn (min. 300 mm) is equivalent
to 1.8 meters.
EXAMPLE If along the way
there and present a curve
elbow and one with a radius of
about 300 mm development
maximum of the pipe
It will be: 8-3,3-1,8 = 2.9 m.
Aerodynamic links
Inside the ejection pipe (upper inlet on the
machine) can condense, especially if the
pipeline itself through relatively cool
environments such as basements or
underground garages. For this reason it is
necessary that such a pipe is in constant
although slight slope towards the chillerto
ensure the return of condensation inside the
unit. Alternatively you must create drainage
points in the valley areas of the holes through
with relative drainage pipes to channel any
condensate into a drain. The junctions between
the various pipe sections and fittings must be
properly sealed to prevent water leakage.
The masking of the holes external must be
carried out only and exclusively with the dates
grids supplied. Other grids not specifically
designed may result in high pressure drops
resulting in the criminalization of the machine
returns. When used in winter seasons or with
temperature External below 20 ° C it is
necessary to protrude a stretch of pipe inclined
downwards to prevent that any drops of
condensation from falling on the wall wetting.

4.1.4 AUTOMATIC WASHING FUNCTION AND QUALITY 'WATER
In order to avoid large formations
of limestone, which would decrease the
efficiency of
machine, the cooler is equipped with a pump
which, at time intervals between 30
minutes and 6 hours, depending on the water
hardness, stops the machine and performs a
washing
exchanger,
a water collection tank and piping.
The action of these washings, it restricts the
formation of limestone deposits and lengthens
considerably
the interval of time between maintenance and
the other.
The washing sequence involves the following
operation:
-
Stop the compressor;
-
discharge capacitor bath water
-
wash cycle;
-
restart the compressor.
During the wash cycle the system circulation
pump remains in operation.
All the sequences set forth above are carried
out automatically by the electronic
card;
In the first phase of start
-up, the service
technician will have to detect the water
replenishing reference values
with the
appropriate test kit.
If the total hardness is less than 20 ° F water
and reference values
are within the limits
stated:
-
Setting up through the installer menu to the
hardness value of the parameter PC76
controller;
PC76 =
Hardness (in French degrees)
From minimum 4 ° F to 20 ° F max;
A
value that will adjust the frequency of
washes during the operation of the unit;
of well water or groundwater are not from the
aqueduct should always be carefully analyzed
and in case conditioned with appropriate
treatment systems. In case of
installation of a
softener in addition to follow the prescriptions
of the manufacturer, to adjust the hardness of
the output is not below 5 ° F (performing also
test the pH and salinity) and verify the
concentration of chlorides in output after the
regeneration of the resins
make-up water setpoints
pH: 6.5 ÷ 7.8
Electrical conductivity: between 250 and 800 seY / cm
Total hardness: between 5 and 20 ° F
Total iron: less than 0.2 ppm
Manganese: less than 0.05 ppm
Chlorides: less than 250 ppm
Sulfur ions: Ions absent ammonia: absent

4.1.5 CONNECTING THE EXHAUST PIPE
In order to periodically expel the salt-rich
water contained in the bowl placed
under the evaporative condenser, the
apparatus is
It equipped with an exhaust system that
includes a pump and a pipe to be connected to
a drain.
This pipe is positioned inside the device
so that at least a part thereof is in the
upper part of the
machine, at a higher level with respect to
the bath water.
This arrangement serves to prevent the
continuous outflow of water in the case
that the connection of external exhaust is
lower than the level of the basin (which is
located approximately at half height
relative to the apparatus).
The diameter of the discharge fitting by pr
edisporre mm is equal to 22. In the case of
discharge into the sewage system, it is
recommended to provide a siphon to prevent
the return of unpleasant odors into the room.
The siphon curve must be lower than the tray
of at least 1.5 m. One must also take into
account that the water discharged may be
present
of solid residues (pieces of limestone or other
small sediments), therefore, the pipes must
not have inside them points where these
residues can stop.

4.1.6 FILLING THE SYSTEM
Once you terminated the hydraulic
connections necessary to proceed to the filling
plant
using the corresponding tap inside the front
panel;
Simultaneously with this it is necessary to
vent the air inside the piping and apparatus by
means of the hygroscopic valve
During all these operations the machine must
be disconnected from the mains
electricity.
If an external auxiliary pump is used the same
should be off.
The system operating pressure must not
exceed 1.5 BAR pump is switched off. In any
case, to check for any leaks in the system at
the time
testing is recommended to raise the test
pressure to be downloaded later to reach the
operating pressure
Once you terminated the electrical connections
and activated the circulation pump check
they are not yet present
residual air.
If this were to happen you have to stop
several times the pump and vent again. To
avoid dangerous cavitation that could damage
the pump and make it less
efficient the whole appliance, the suction
pressure, with the pump turned on,
measurable by the pressure gauge on the
appliance, it must not be less than 0.6 BAR.
