9. Routine Maintenance
9.1 Warning
ATTENTION: BEFORE UNDERTAKING ANY
MAINTENANCE OPERATIONS, MAKE SURE
THE MACHINE IS NOT AND CANNOT BE
ACCIDENTALLY SWITCHED ON. IT IS THEREFORE NECESSARY TO
REMOVE POWER FOR EACH MAINTENANCE OPERATION.
• Carrying out maintenance operations on the heat pump is the
customer's responsibility.
• Only authorised personnel who have been previously trained and
qualified can carry out maintenance operations.
• Do not move/repair the unit yourself
• If the unit must be disassembled, protect hands with working gloves.
Upon start-up and after a few days of operation, check the tightness
of bolts in the heat exchanger flange, easily accessible thanks to the
removable flange cover cups and general control of the electrical
absorption during the operation of the heat pump and the electric heater.
9.2 Annual checks
• Check of general unit conditions.
• General control of the electrical absorption during the operation of the
heat pump and the electric heater.
• General check of electrical resistance.
• Check on all electrical connection tightening.
• Check programming parameters.
• Check of fan and compressor contact conditions.
• Check of hydraulic circuit filters and air filters.
• Check conditions of magnesium anode to plan periodic replacement.
• Check of system safety valve functioning.
• Check of system expansion tank preloading.
• Check of general unit and system conditions and verification of lack
of leaks.
• Refrigeration load check.
• Checking of refrigeration circuit conservation conditions.
• Check of bolt, nut, flange and water connections tightening, which
vibrations may have loosened.
10. Operation
The maximum operating temperatures contained in this document and
on the device data plate are to be understood as maximum resistance
temperatures of the internal tank covering. The maximum operating
temperature must comply with rules on reducing energy consumption. In
Italy, see Law 10/91 and subsequent decrees and supplements.
10.1 Troubleshooting
Whenever abnormal heat pump behaviour is observed, without being
accompanied by alarms described in the
“Alarm Table”,
check the
following table to see if the fault is easily solvable before contacting
technical support.
FAULTS
POSSIBLE CAUSES
Heat pump does not
switch on
• no electricity
• the main circuit switch is open
• the plug has not been inserted into the
outlet, or not enough to make contact
• the safety fuse on the outlet is cut off
The compressor and/or
fan do not start
• the set safety times have not passed
• the system is full (no charge required,
[Hot water] icon is bright)
• the electrical connection is loose
Repeated starting and
stopping of the heat
pump
• set point and/or differential settings are
incorrect
The heat pump keeps
running without stopping
• there is an excessive heat load
• set point and/or differential settings are
incorrect
The system produces
vibrations and unusual
noises
• covering shells vibrate
• air channels and/or hydraulic pipes
vibrate
Electrical resistance
does not switch on
• no intervention required
• the plug has not been inserted into the
outlet, or not enough to make contact
In general, try to switch the unit off and back on again before contacting
technical support.
ATTENTION !
If the operator fails to remedy the fault, switch off the
machine and contact the manufacturer or authorised
technical support, citing the unit identification reported in its label.
11. Disposal
At the end of the product's life cycle, its components must be
disposed of in compliance with current regulations.
In particular, European Directive 2002/96/EC on electrical and
electronic equipment waste, which requires disposal outside
the normal flow of solid waste.
Appliances to be disposed of should be collected separately to optimise
the recovery and recycling of materials which they are composed of and
to reduce potential hazards to health and environment. The metallic
components must be given to an authorised metallic materials collection
operator for recycling, while non-metallic components shall be given to
operators authorised for their disposal. Products must be dealt with, if
disposed of by the end user, as assimilable to urban refuse, therefore
in compliance with municipal regulations. It should not in any case be
treated as household waste
