Compressor
In the case of compressor replacement:
●
Disconnect the unit from power supply.
●
Completely empty the refrigerant charge using a speci
fi
c
recovery unit for R-410A
●
Disconnect electrically the compressor.
●
Carefully unsolder the suction and
discharge piping.
●
The compressor is
fi
xed onto the
platform with 4 screws.
●
Unscrew the
fi
xings.
●
Place the new compressor and
check that it has a su
ffi
cient oil
charge.
Warning: when tightening the compressor screws, please
consult the maximum torque that can be applied.
If a torque wrench is not available,tighten them until they are
snug then tighten a further ¾ turn.
●
Solder the suction and discharge piping.
●
Connect the compressor in accordance with the wiring
diagram.
●
Make vacuum and next, reload the gas into the unit according
to charge data provided in the table of paragraph 14.1
“General recommendations” and in the unit’s data plate.
Dryer
fi
lter
●
The
fi
lter function is the preserve the cooling circuit clean and
without humidity, neutralizing the acids that can be found in
the cooling circuit.
●
Measure the di
ff
erence in the temperature of the pipes at the
dryer inlet and outlet.
●
If necessary, replace.
14 - MAINTENANCE
Active recovery (optional)
●
A cooling recovery circuit is optionally available for these
units (CR and CT assemblies). It is a complete circuit with
independent electronic control.
●
The same recommendations for the maintenance of the
components of the main circuits must be followed for the
components of this circuit.
Refrigerant leak detector (optional)
The gas detector sensor is a device that
signals leaks in refrigerant. This sensor
is installed next to the supply fan. In
case of alarm, it is reset manually.
Maintenance:
●
Annual testing: it is necessary to carry out testing every year.
●
Every 3 years: a taring test is recommended.
●
Every 5/6 years: it is recommended that the gas detection
element be replaced and calibration performed.
Note: Check the documentation attached to the leak detector
for taring and calibration testing.
Mixing boxes (optional)
In units with mixing box assemblies, it is advisable to check the
condition of the servomotors of the motorised dampers.
Servomotors
Centrifugal fan (optional)
●
Verify that the turbine and the motor remain clean.
●
Foresee having a spare belt set for the fans.
●
The motors and the fans have bearings that have been
lubricated and sealed and, thus, do not need further lubrication.
Use safety gloves for this task. Take care with the sharp
parts of the coil.
Air coil
●
Check that the coil is free from dust and grease.
●
Cleaning the accumulated dust on the coil can be performed
using a soft-bristled brush or a vacuum cleaner perpendicular
to the
fi
ns or with a low-pressure water cleaner. Grease can
be removed with water with degreaser. Do not put stress on
the
fi
ns as they could deform.
Note: an optional protective grille can be
fi
tted to the coils.
