Safety considerations
1.6 Maintenance
Schedule periodic inspections and maintenance work in order to prevent or reduce repair costs.
Disconnect voltage before any operation and wait 10 minutes before any action on electrical components.
1.7 Changes
All modifications to the unit will invalidate the warranty and void the manufacturer’s liability.
1.8 Fault or malfunction
Disable the unit immediately if there is a fault or malfunction.
Contact a service centre authorised by the manufacturer.
Request the use of original spare parts.
Using the unit when there is a fault or malfunction:
• voids the warranty
• may compromise the safety of the unit
• can increase repair costs and times
1.9 User training
The installer is to train the user on:
• Switch on/o
• Change setpoint
• Standby mode
• Maintenance
• What to do/not do in case of failure
1.10 Data updating
The continual improvements to the product may result in changes to the data shown in this manual.
Visit the manufacturer’s website for up-to-date data.
1.11 Information for the User
Keep this manual together with the wiring diagram in an accessible place for the operator.
Make a note of the unit's identification data so that they can be provided to the service centre in the event
of a service request (see paragraph “1.11.2 Unit identification” on page 8).
Provide a logbook dedicated to the unit in which any interventions carried out on the unit can be noted and
tracked, making it easier to suitably record the various operations and facilitate troubleshooting.
1.11.1 Ensure the installer is trained in:
