Essential recommendations for the electrical
safety

turn off the boiler by pushing on the ON/
OFF master switch.
• Isolate the external power supply of
the appliance before performing any
operation, unless it is required to take
measurements or perform system setup.
Essential recommendations for safety
• Water flowing out of the drain valve may
be extremely hot and could cause severe
scalding.
• Do not use solvents to clean any of the
components. The components could be
damaged, resulting in unreliable or unsafe
operation.
Essential recommendations for the correct
operation of the appliance
• It is recommended to have the boiler
serviced at least once a year or every
1,500 hours by a qualified technician,
preferably at the start of the heating
season. More frequent servicing may be
required depending on boiler use. Please
consult your installer for advice.
• The boiler maintenance will be carried out
by a qualified engineer, and the defective
parts may only be replaced by genuine
factory parts.

seals on the removed components before
reinstalling them.
