2 Introduction

This installation and maintenance manual is to be
considered an integral part of the present heat pump
(hereafter referred to as equipment).
The manual must be kept for future reference until the
heat pump itself has been dismantled. This manual is
intended for both the specialised installer (installers –
maintenance technicians) as well as the end user.
The installation modes to be complied with in order to
achieve a correct and safe operation of the equipment
as well as methods of use and maintenance are
described in this manual.
In case of the sale of the equipment or the change of
owner, the manual must accompany the equipment to
its new destination.
Before installing and/or using the equipment, read this
instruction manual carefully and, in particular, chapter 5
relating to safety.
The manual must be kept together with the equipment
and, in any case, it must always be at the disposal of
the qualified personnel in charge of installation and
maintenance.
The following symbols are used inside the manual in
order to rapidly find the most important information

Operating principle

The equipment belonging to the 1.9 kW and 2.9 kW
series is capable of producing domestic hot water
mainly by using heat pump technology. A heat pump is
capable of transferring thermal energy from a low
temperature source to another with a higher
temperature and vice versa (heat exchangers).
The equipment uses a water circuit consisting of a
compressor, an evaporator, a condenser and a
lamination valve; a liquid/gas coolant flows inside this
circuit (see paragraph 4.6).
The compressor creates a difference in pressure inside
the circuit that allows a thermodynamic cycle to be
obtained: this sucks the coolant fluid in through an
evaporator, where the fluid itself evaporates at a low
pressure by absorbing heat, it is compressed and
driven towards the condenser where the fluid
condenses at a high pressure releasing the absorbed
heat. After the condenser, the fluid passes through the
so-called "lamination valve" and by losing pressure and
the temperature starts to vaporise, it re-enters the
evaporator and the cycle starts all over again.
