The water heater is supplied with a sufficient amount of R134a refrigerant for its operation. This refrigerant fluid does
not damage the atmosphere's ozone layer, is not flammable and does not cause explosions, however any maintenance
activities or work on the refrigerant circuit must be carried out by authorised personnel only and with the necessary
equipment.

WARNING! Incorrect installation may cause harm to persons and animals or damage to objects, for which the
manufacturer will not be held liable.
The installer is obliged to observe the instructions outlined in this manual.
Once installation is complete, it is the installer's duty to inform and instruct the user on how to operate the water heater
and carry out the main operations correctly.
