Above data for fans and motors, which are mandatory regarding eco-design regulation, are provided for a stand-alone component (not
included in the chiller system).
12.6 - Electronic expansion valve (EXV)
The EXV is equipped with a stepper motor (2785 to 3690 steps,
depending on the model) that is controlled via the EXV board. The
EXV is also equipped with a sightglass that permits verification of
the mechanism movement and the presence of the liquid gasket.
12.7 - Moisture indicator
Located on the EXV, permits control of the unit charge and indicates
moisture in the circuit. The presence of bubbles in the sight-glass
indicates an insufficient charge or non-con-densables in the
system. The presence of moisture changes the colour of the
indicator paper in the sight-glass.
12.8 - Filter drier
The role of the filter drier is to keep the circuit clean and moisture-
free. The moisture indicator shows, when it is necessary to change
the element. A difference in tempera-ture between the filter inlet
and outlet shows that the element is dirty.
12.9 - Sensors
The units use thermistors to measure the temperature, and
pressure transducers to control and regulate system operation.
Refer to the SmartVu
TM
control manual for a more detailed
explanation.
12.10 - Service valve (option 92)
The unit can be equipped with optional service valves to facilitate
maintenance and repair operations.
If option 92 is ordered, each refrigerant circuit will be supplied with
shut-off valves on the compressor economiser, discharge and
suction lines.
ATTENTION: The compressor suction valve must be used
without pressure difference at the terminals. If there is a
pressure difference, leak-tightness at the valve may be lost
and the valve can even fail altogether.

Power factor correction capacitors
(option 231)
They garantee a minimum power factor performance of 0.95 when
unit operates at a condition that involves a power input that
exceeds the Eurovent standard condition.
A fix capacitor bank is switched at start of each compressor. It
provides individual power factor correction for each machine
refrigerant circuit.
Capacitors are dry type : no risque of leakage.
The capacitors are selected for each compressor as per below

Caution:
-
Operation of the unit without capacitors results in raise
of the unit absorbed current . This is likely to happen if
the internal thermostat is active if the ambient temperature
is too high or if the cooling system is defective.
-
The safe operation of the capacitors requires that they
are checked periodically : refer to the document
dedicated for this purpose
