8 Maintenance and cleaning
A periodic maintenance is necessary first of all to keep a correct
and efficient operation of the heat pump, in order to reduce
wear and deterioration of components.
The frequency of interventions is decided by the user, and
mainly it depends from two factors:
• The mode of use: we suggest a maintenance once a year
if the machine works in one mode (heat/chiller pump),
or every six months if the machine is used with both of
operation modes.
• The place of installation: if the installation is in places
particularly subject to pollution or to the presence of
particulate that could block the battery, we suggest to
perform an appropriate monitoring of work condition of
the battery and, if necessary, provide to a more frequent
maintenance.
WARNINGS!
Turn off power of the machine before of any operation of
maintenance to avoid dangerous accidents due to the activation
of some operation logics of the machine.
8.1 Cleaning of the battery
During the operation of the machine it is possible that the coil
filled is partially clogged for the presence of leaves or various
kind of encrustations, causing a malfunction of the heat pump
too. It is possible then to clean the battery with a jet of air under
pression in a direction parallel to that of wings, we also suggest
to remove possible deposits in the battery compartment:
• Clean the front surface
• Remove the top panel according to the picture
WARNINGS!
Avoid the contact with the wings of the battery since it can cause
stab wounds.
Avoid to bend the wings of the battery since it reduces the
performances of the machine. If the wings are bent, contact the
appropriate authorized service center.
8.2 Cleaning of the condensate drain
Make sure that the condensate drainpipe is in the correct position
and no clogged, to allow the correct drain of the condensate
depositing on the battery during the operation in the heat pump.
8.3 Cleaning of hydraulic system side
To clean the filter lead to atmospheric pressure the hydraulic
circuit in correspondance of the impurities collector, remove the
filter unscrewing the seat to clean it.
For the assembly follow the same steps in reverse order and
make sure that the monitoring of the filter is correct and that
the screw is tight.

9 Electrical connections
9.1 General information
• Before of starting any operations equip yourselves with
the safety devices, make sure that the unit is in stable
equilibrium and there aren’t close elements in tension.
• The power line has to be equipped with protection systems
able to stop the short-circuit current tenendo considering
the features of the machine.
• Make reference to the electric scheme of the unit.
• As first connection realize the earthing.
• Before of powering the unit, all the protections of the line
have to be enabled.
9.2 Laying operations
• Lay the cables at a certain distance with respect to lines
with different voltage or to systems that can create
electromagnetic interference.
• Avoid parallel laying with other cables, it is allowed only
90° layout.
• Pass the power cords and control network cable of the
machine through the special holes (position 22) see the
dimensions of the machine.
