GENERAL
The CE marking of the products involves the constant control of
production, with the aim to guarantee the conformity of the
appliances to the safety and performance characteristics of
verified samples. The manufacturer provides checks on the
whole production and especially testing final, in which the
project parameters are checked with electrical and functional
tests, in compliance to the standards of the quality assurance
system company. Assistance and maintenance services can be
performed by a Technical Assistance Center authorized.
17.1 USE OF INSTRUCTIONS
Read this section carefully of the user manual, in addition to the
previous "Section A" in which they can be found general
information on the appliance and on the its technical
characteristics. Failure to comply with what is stated in this
manual involves the forfeiture of the conditions of guarantee.
This manual constitutes integral part of the product and must be
carefully stored for any use future or for consultation.
17.2 IMPROPER USES - RECOMMENDATIONS
The devices are designed and manufactured
for water heating
in heating systems winter air conditioning and DHW
production and should only be used for this purpose, in
relation to their technical specifications and performance.
All uses not expressly indicated in this manual is
considered improper and are not allowed; in particular not
the use of the devices is foreseen in industrial processes
and / or installation in environments with corrosive

MAINTENANCE
WARNING! Before each operation control, maintenance, or
whatever involves access to internal parts the appliance,

16.1 CLEANING THE EXCHANGERS
Cleaning the finned air exchanger / refrigerant gas must be
carried out at least twice a year, at the start of the season
functioning and whenever it is made necessary for
installation conditions details. Keep the exchanger clean
involves a constant return over time, with reduced
management costs.
To perform cleaning operations, use a vacuum cleaner or a

air to pass with attention in the spaces of the fins.
16.2 ANNUAL CHECK
To keep the system efficient, we recommend to carry out
the following checks by a Center Authorized Technical
Assistance:
- refrigerant charge control and parameters of
operation;
- check voltage supply, electrical absorption;
- functionality of the control devices and of safety;
- cleaning the water filter and the exchangers;
- control of the hydraulic system, of the presence of air in
the pipes and possible filling integration;
- check and tighten connections electric and hydraulic;
- verification of the envelope, with particular
watch out for corrosion triggers.
For appliances installed near the sea a periodic check is
