Packing items (plastic bags, polystyrene foam, nails, etc.) must be kept out of the reach of
children, as they are potentially dangerous.
The appliance must only be used for the purposes for which it has been designed. Any
other use is considered inappropriate and therefore dangerous. The manufacturer does
not accept any contractual or extra-contractual liability for any damage caused by im-
proper 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

The unit uses a water/ammoniac absorption cycle for hot water production. The ammo-
niac is in water solution inside a sealed circuit tested for tightness by the manufacturer.
In case of coolant leaks, switch off the electrical power and gas supplies only if this can be
done in total safety. Contact your Technical Assistance Centre.
Frequent topping up of the hydraulic with water can result in 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
5.1 Chemical and physical parameters of water

31 will damage the unit's water/am-
monia exchanger.
Close the gas supply before working on the gas circuit. On completing work on the gas
circuit, check for leakages as required by established regulations.
