Instructions and technical norms

The purchaser pays for the appliance’s installation, which must be 
carried out by qualified personnel only, in conformity with national 
regulations in force and any provisions emitted by local author-
ities or bodies responsible for public health, and in accordance 
with the specific manufacturer indications contained in this manu-
al. The manufacturer is responsible for the product’s conformity to 
the relevant construction directives, laws and regulations in force 
at the time the product is first commercialised. The designer, in-
staller and user are each exclusively responsible, in their respec-
tive fields, for knowing and observing the legal requirements and 
technical regulations concerning the design, installation, opera-
tion and maintenance of the appliance. 
Any reference to laws, regulations or technical specifications 
contained in this manual is purely for information purposes; any 
new laws introduced or modifications to existing laws are not in 
any way binding on the manufacturer towards third parties. It is 
necessary to ensure that the power supply network to which the 
product is connected complies with the EN 50160 norm (under 
penalty of warranty invalidation). 

Field of application

This appliance is intended for hot water production for domestic 
use or similar, at temperatures below boiling point.
The appliance must be hydraulically connected to a domestic wa-
ter supply line and to a power supply network.
Air ducts may be used for the entry and discharge of processed 
air. 

It is forbidden to use of the appliance for uses other than those 
specified. 

Any alternative use of the appliance constitutes im-

proper use and is prohibited; in particular, the appliance may 
not be used in industrial cycles and/or installed in environments 
exposed to corrosive or explosive materials. The manufacturer 
shall not be held liable for any damage due to faulty installation, 
improper use or uses deriving from behaviour that is are not rea-
sonably predictable, and incomplete or careless implementation 
of the instructions contained in this manual.

Operating principle

The efficiency of a heat pump operation is measured by the Co-
efficient of Performance (COP), i.e. the ratio between the energy 
supplied to the appliance (in this case, the heat transferred to the 
water to be heated) and the electrical energy used (by the com-
pressor and the appliance's auxiliary devices). The COP varies 
according to the type of heat pump and to its relative conditions 
of operation.
For example, a COP value equal to 3 indicates that for every 1 
kWh of electrical energy used, the heat pump supplies 3 kWh of 
heat to the medium to be heated, of which 2 kWh are extracted 
from the free source.

Packaging and supplied accessories

The appliance is anchored to a wooden pallet and is protected with 
polystyrene top cover, wooden edge protectors, and external card-
board; all the materials are recyclable and eco-compatible.
The following accessories are included:
-  Connection pipe for condensation water.
-   2 ¾” dielectrics joints.
-  Instruction manual and warranty document.
-  Energy label and product fiche.
-  2 adapters for Ø150 and Ø160 ducts.
