DOMESTIC HOT WATER HEAT PUMP
Instruction for installation and maintenance
EN
This installation and maintenance manual are to be considered an integral part of the heat pump (hereafter referred to as equip-
ment).
The manual must be kept for future reference until the heat pump itself has been dismantled. This manual is intended for both the
specialized 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 4 related 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 quickly find the most important information:

Dear Customer,
Thank you for having purchasing this product.
The TESY, has always paid a great deal of attention to environmental problems, therefore, it has used technologies and materials
with a low environmental impact to manufacture its products in conformity with WEEE – RоHS (2011/65/ЕU and 2012/19/EU com
-
munity standards.
The conformity of the content of these user instructions with hardware and software has been submitted to thorough verification.
Regardless of this, it is still possible for some non-compliance to occur; therefore, no liability will be assumed for complete confor-
mity.
In the interest of achieving technical perfection, we reserve the right to carry out modifications to the equipment construction or to
data at any time whatsoever. Therefore, we do not accept any liability claims whatsoever attributable to instructions, figures, draw
-
ings or descriptions, without prejudice to errors of any kind.
TESY shall not be held responsible for damages attributable to misuse, improper use, or as a consequence of unauthorized repairs
or modifications.
WARNING! The equipment can be used by children of at least 8 years of age as well as by people with re-
duced physical, sensory or mental abilities or by those who lack the necessary experience or knowledge, as
long as they are supervised or after they have received instructions relating to the safe use of the equipment
as well as explanations relating to the use of such equipment.
Children must not play with the equipment. Cleaning and maintenance intended to be carried out by the
user must not be performed by unsupervised children.
These user instructions contain information protected by copyright. It is forbidden to photocopy, duplicate, translate or record these
user instructions on memory equipment, either in whole or in part without prior authorization of TESY. Any breaches shall be subject
to the payment of compensation for any damage caused. All rights are reserved, including those deriving from the issuing of pat-
ents or the registration of utility models.
The equipment 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.
The equipment uses circuit consisting of a compressor, an evaporator, a condenser and a throttle 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 “throttle valve” and by losing pressure and the temperature starts to vaporize, it re-enters the
evaporator and the cycle starts all over again.
The operating principle of the equipment is as follows (Fig. 1):
I-II: The coolant fluid sucked in by the compressor, flows inside the evaporator and while it evaporates, it absorbs the “ecological”
heat given by the air. At the same time, the ambient air is sucked in by the equipment by a fan; the air loses its heat by passing over
the finned-tube battery of the evaporator;
