2. SAFETY CONSIDERATIONS
The detailed instructions in this section cover important aspects for your safety; as such they must be strictly
complied with.
2.1. REFRIGERANT CIRCUIT
The refrigerant circuit uses refrigerant R410A as its working fluid. This refrigerant is not harmful to the
environment as it does not contain chlorine, and therefore does not contribute to the destruction of the ozone
layer. However, any intervention on the refrigerant circuit must only be performed by authorised personnel in
accordance with applicable local regulations and the instructions provided in this manual.
TOXICITY
Under normal operation of the heat pump the toxicity of the refrigerant is nil. However, despite its low
toxicity, injuries could occur under abnormal operating conditions of the equipment.
DANGER!
In case of accidental refrigerant leakage, do not directly touch the area where the leakage has
occurred, as this could result in severe frostbite injuries.
The maximum working pressure of the refrigerant circuit is 4.2 MPa (42 bars).
Do not touch the piping, compressor or other components of the refrigerant circuit during or
immediately after operation of the heat pump, as they may be at very high or low temperatures.
Touching them could result in burns from the heat or cold. If these components need to be touched,
allow sufficient time for the temperatures to stabilise and wear protective gloves to avoid injury.
DANGER!
All the installation and maintenance work described in this manual must be performed by an
authorised engineer.
Improper installation or use of the equipment could cause electrocution, short circuits, leakage of
working fluids, fire or other personal injury and/or material damage. If you are unsure of the
procedures for installation, maintenance or use of the equipment, contact your local dealer or
technical support for advice.
If you detect a malfunction in the unit, contact your local dealer or technical support to answer any
questions.
This equipment should not be handled by people with physical, sensory or psychological disabilities,
children and people with no suitable experience or knowledge, unless it is under the supervision or
direction of a person responsible for their safety.
When carrying out installation, maintenance or commissioning of the heat pump, always use
appropriate personal protective equipment.
Keep the plastic bags included in the packaging out of the reach of children, as they could result in
injury through asphyxia.

The refrigerant in a gaseous state is heavier than air, as such it tends to accumulate at low levels. If
the equipment is installed in a location where the accumulation of refrigerant vapour at ground level
is possible, it should be well ventilated.
Direct exposure of the refrigerant to a flame produces toxic gas. However, this gas can be detected
by its odour when at concentrations well below the permitted limits. If an unusual odour is detected,
evacuate and ventilate the area to ensure the complete removal of the gas.
In the event of accidental refrigerant leakage, ventilate the area immediately.
Anyone who has come into contact with refrigerant vapour must evacuate the area immediately and
breathe fresh air.
INFLAMMABILITY
Under normal conditions, there is no risk of explosion or combustion of the refrigerant contained in the
refrigerant circuit.
REPAIRS AND SCRAPPING
When carrying out repairs on the refrigerant circuit, the refrigerant contained within the circuit must not
be released into the atmosphere, but must be collected and destroyed in special treatment plants
designed for this purpose.
Since R410A is a mixture, if a leakage occurs the additional refrigerant must be refilled in a liquid state.
Refilling the refrigerant in a gaseous state alters its composition and may cause the heat pump to
malfunction.
Before scrapping the heat pump, the refrigerant contained inside must be collected for destruction in a
treatment plant, in accordance with current regulations in force.
2.2. HYDRAULIC CIRCUITS
Installation and subsequent interventions on the heating, brine or DHW circuits must only be performed by
authorised personnel in accordance with applicable local regulations and the instructions provided in this
manual.
DANGER!
Do not touch the piping or other components of the heating, brine or DHW circuits during or
immediately after operation of the heat pump, as they may be at very high or low temperatures.
Touching them could result in burns from the heat or cold. If these components need to be touched,
allow sufficient time for the temperatures to stabilise and wear protective gloves to avoid injury.

8 ECOFOREST Geotermia
2.3. ELECTRICAL SYSTEM
Any intervention on the electrical system must only be performed by an authorised electrician in accordance
with applicable local regulations and the instructions provided in this manual.
DANGER!
Before performing any operation on the electrical panel, disconnect the power supply.
When removing the upper cover of the heat pump, the electrical panel will be exposed and its
components may accidentally be touched. During installation and maintenance of the equipment
never leave the electrical panel unattended while it is exposed.
Do not touch any component of the electrical panel with wet hands as this could cause an electric
shock.
Do not touch any electrical component of the heat pump (including pumps, valves, DHW auxiliary
heating elements, etc.) during or immediately after operation of the equipment, as this could result in
burns or electric shocks.
Do not use water or other liquids to clean the heat pump, as this could cause an electric shock or fire.

3.2. OPERATING PRINCIPLES
ecoGEO HP heat pumps are designed to provide heating and DHW all year round, with easy installation and
always ensuring maximum energy efficiency.
Installations with geothermal heat pumps are composed of three main circuits (refrigerant circuit, the brine
circuit and the production circuit) in which, by using different fluids (refrigerant, antifreeze mixture and water)
thermal energy is transported between the ground and the heating system of the building, a DHW inter-
accumulator and/or a pool. These circuits use different fluids, and therefore the transfer of thermal energy
from one fluid to another takes place through heat exchangers, where the higher temperature fluid transfers
heat to the fluid at a lower temperature without mixing.

11 ECOFOREST Geotermia
Described below are modes of operation made possible by the different technologies incorporated in
ecoGEO HP geothermal heat pumps.
HEATING MODE
During the normal operating cycle, the heat pumps extract energy from the ground to produce hot water
for the heating system. Its operation can be divided into four sub-processes that recur cyclically.
1. The antifreeze mixture is circulated by a circulator pump via the brine system, where it absorbs heat
from the ground and then via the evaporator, which transfers heat to the refrigerant fluid in the
refrigerant circuit. The refrigerant in the evaporator is at low pressure and temperature, and due to
the heat absorbed from the antifreeze mixture is vaporised.
2. The refrigerant vapour from the evaporator is drawn in by the inverter compressor (variable speed),
where its pressure and temperature (hot gas) rise just enough to meet the demands of the heating
system at any given moment.
3. The hot gas from the compressor is channelled to the condenser, where it transfers heat to the water
in the heating system. As a result of this heat transfer, the refrigerant gas is cooled and condensed,
changing to a liquid state.
4. The refrigerant fluid in a liquid state is channelled back to the evaporator through the electronic
expansion valve, which precisely controls the flow of recirculated refrigerant according to the heating
needs. At the same time, as it passes through the electronic expansion valve, the pressure and
temperature of the refrigerant reduces so that once again it is able to absorb heat from the antifreeze
mixture in the evaporator.
FREE COOLING MODE
The heat pump is able to use an additional external heat exchanger that allows direct heat exchange
between the antifreeze mixture in the brine circuit and the water in the heating system, so that the
refrigerant circuit is not used. In this operating mode the compressor remains off and the heating and
brine circuit divert to the free cooling exchanger using 3-way valves. In this way, the equipment sends
fresh water to the heating system obtained by heat exchange with the antifreeze mixture from the brine
system, all with the sole use of the circulation pump.
This technology allows homes (or shop premises) to be heated throughout the year in temperate zones
where temperatures in the warm months do not reach excessively high values. It is noteworthy that in
FREE COOLING mode energy consumption is very low due to the high efficiency of the circulator
pumps.
DHW MODE
The production of domestic hot water (DHW) is performed by sending the hot water from the condenser
to the DHW inter-accumulator coil.
If the electric backup is enabled, the legionella protectionheater is activated only in the final stage of
heating to raise the temperature of water to the setpoint. This restricts use of the electric heater to the
minimum required.
LEGIONELLA PROTECTION MODE
The heat pump controls an electric heater installed in the DHW storage tank to perform a weekly
program to prevent possible outbreaks of legionella. In this operating mode the heat pump raises the
temperature of the storage tank to the temperature setpoint and then the electric heater is activated to
raise the temperature of the DHW storage tank to 65 °C, the temperature at which the bacteria does not
survive for more than 20 minutes. It is recommended that this heating be carried out at night, when there
is no DHW consumption.

12 ECOFOREST Geotermia
POOL MODE
Pool production is performed by sending hot water to a heat exchanger through which water is supplied
to the pool.
FAULT MODE
In the event of any failure of the heat pump which stops the compressor from operating, activation of the
electric legionella protection heater for daily DHW production is permitted, so that the user is guaranteed
DHW production if there is a fault in the heat pump.

MENU 1.1. ON/OFF
ON/OFF. Allows the heat pump to be switched between ON / OFF / REMOTE. The selected state can be
modified via the programming of the schedule or alarm. Also allows the operating program to be selected
between WINTER / SUMMER / AUTO / REMOTE. In both cases the REMOTE option is only available if
the installer has been previously enabled in menu 2. INSTALLER / REMOTE CONTROL. If the REMOTE
option has been selected, the heat pump responds to the control signals from an external device in the
corresponding terminals.
