manufacturer does not accept any contractual or extra-contractual liability for any
damage caused by improper use of the appliance.
The appliance is not intended to be used by persons (including children) whose
physical, sensory and mental capacities are impaired, or who lack the necessary
experience and knowledge, unless they are supervised or instructed in its use by
persons responsible for their safety. Children must be supervised to ensure that
they do not play with the appliance.
The unit uses a water/ammonia absorption cycle for hot/cold water production. The
ammonia is in a water solution inside a sealed circuit tested for leaks by the
manufacturer. In case of refrigerant leaks, switch off the electrical power and gas
supplies only if this can be done in total safety. Contact your Authorised Service
Center.
The safety valve must be ducted to the outdoors. Refer to Chapter 2.9 on page 31.
The unit MUST NOT BE OPERATED if the safety valve is not ducted.
Frequent water filling in the loop may result in unit damage due to scale and
corrosion, depending on the quality of the water being used. Make sure the system
is water tight and that the expansion tank is operational.
Concentrations of chlorides or free chlorine in the circuit above the values given in
Table 17 on page 31 will damage the unit heat exchangers and void the warranty.
Shut off the gas supply before working on the gas circuit. Upon completing work on
the gas circuit, check for leaks as required by regulations.
Do not operate the appliance if dangerous conditions exist: smell of gas in the
pipeline or near the appliance; parts of the appliance submerged in water or
otherwise damaged; controls or safety components bypassed or defective.
In these cases, ask for assistance to a qualified installer or Service Company.
Do not remove safety guards because there are components moving also during
the start-up and shut-down cycles of the unit. Make sure the appliance cannot be
started up inadvertently.
POISONING HAZARD
Make sure the flue gas components are tightly sealed and compliant with local and
national regulations.
If the appliance is installed indoors, insufficient or non compliant ventilation (see
installation instructions) can result in dangerous leak of flue gases. If the installation
is not compliant, do not start up the appliance.
Inform the installer and the end user.
