10 Maintenance and cleaning
A periodic maintenance is necessary in particular to keep a
correct operation of the heat pump, to reduce the ususry and
the deterioration of the components.
The frequency of the intervention is decided by the user, and it
depends on two factors:
•
Mode of use: an annual maintenance is suggested, if
the machine works in one mode (heat pump/chiller), or
semiannual if the machine is used with both operation
modes.
•
Installation place: if the installation is made in places
particularly subjects to pollution or particulate matter that
could block the battery, it is suggested to properly monitor
work conditions of the battery and, if necessary, provide to
a more frequent maintenance.
WARNINGS!
Turn off the power to the machine before any maintenance
intervention to avoid dabgerous injuries caused by the activation
of some operation systems of the machine.
10.1 Cleaning of the battery
During the operation of the machine it is possible that the coil
finned is partially blocked by leaves or incrustations, causing
also the malfunction of the heat pump. It is possible to clean
the battery with a pressure air jet in parallel direction to the
fins, it is also suitable to remove possible deposits in the battery
compartment:
•
Clean the fron surface
•
Remove the top panel as shown in figure
WARNINGS!
avoid the contact with the fins of the battery because you can
cut.
Avoid to bend the finns of the battery because it reduces the
performaces of the machine. In case of bended fins, contact
authorized service.
10.2 Cleaning of condensate drain
Make sure the condensate drain tube is in the correct position
and not blocked, to allow the right condensate flow depositing
on the battery during the operation of the heat pump.
10.3 Cleaning of hydraulic system side
Concerning the cleaning of the filter portare lead the hydraulic
circuit to atmospheric pressure in corrispondance of impurities
collector, remove unscrewing the seat and clean it.
Concerning the assembly follow the same steps in reverse order
and make sure that the assembly of the filter is correct and the
screwing is sealed.

10.4 Cooling circuit maintenance
The machine is equipped with a security valve ensuring the
reduction of the inside pressure to the cool circuit in case of
outside heat generation (for example in case of fire). To ensure
a correct operation of the valve, contact the manufacturer and
make sure to replace it verey 4 years.
WARNINGS!
The direct contact between the skin and the refrigerant outgoing
from the security valve causes serious lesions. Don’t pause near
the valve.
11 Electrical connection
11.1 General information
•
Before starning any operation adopt security devices, make
sure the unit is in a stable balance and there aren’t any
tension elements nearby.
•
Power line has to be equipped with protection devices able
to stop the short-circuit current considering the situation
of the machine.
•
Make reference of the wiring diagram of the unit.
•
The first connection is the grounding.
•
Before powering the unit, all the line protections have to
be enabled.
