2. SAFETY ISSUES
The indications outlined in this section cover important issues on your safety; please follow them carefully.
2.1. REFRIGERANT CIRCUIT
The refrigerant circuit uses R410A as working fluid. This refrigerant is eco-friendly, as it is chlorine-free and,
therefore, does not contribute to ozone layer depletion. However, any action on the refrigerant circuit should
be carried out by authorized personnel only and in accordance with the applicable local regulations and the
instructions outlined in this manual.
TOXICITY
Under normal operating conditions, the coolant toxicity is nil. However, in spite of its low toxicity, it could
result in personal injuries under unusual equipment operating conditions.
In its gaseous state, the refrigerant is denser than air, thus tending to accumulate in lower levels. If
the equipment is installed in a location where it is possible that refrigerant vapour accumulates at
ground level, it should be well ventilated.
DANGER!
In the event of accidental refrigerant leakage, avoid touching the leaking area directly. Otherwise,
serious freezer burns could occur.
The maximum operating pressure of the cooling circuit is 4.2 MPa (42 bar).
Avoid touching the pipes, the compressor or other refrigerant circuit parts during or immediately after
operating the heat pump. These could be at high or low temperature, and touching them could result
in heat or freezer burns. If you need to touch these pieces, allow sufficient time for temperatures to
stabilize and use protective gloves to prevent injuries.
DANGER!
All installation and maintenance work must be performed by an authorized technician following the
indications outlined in this manual.
An improper installation or misuse of the equipment could result in electrical shock, short circuits,
working fluid leakage, fire or other injuries and/or property damages. If you are unsure about the
equipment installation, maintenance or operation procedures, please contact your local dealer or
customer services for advice.
If you detect unusual performance in the unit, please contact your local dealer or customer services
to resolve your concerns.
This equipment must not be operated by persons suffering any type of physical, sensorial or
psychological disability, children or persons lacking the necessary experience or knowledge, unless
they have been given supervision or instruction concerning use by a person responsible for their
safety.
During the installation, maintenance or commissioning of the heat pump, please always wear
appropriate personal protective equipment.
Keep all plastic packaging bags away from children to prevent suffocation.

Direct exposure of the refrigerant to flames produces toxic gas. However, this gas can be detected
by its smell in concentrations well below the allowable limit. If you detect an unusual smell, evacuate
and ventilate the area until you are sure that the gas has been fully eliminated.
In the event of accidental refrigerant leakage, ventilate the area immediately.
Anyone who has had contact with the refrigerant vapour should evacuate the area immediately and
breathe fresh air.
FLAMMABILITY
Under normal conditions, there is no risk of explosion or combustion of the refrigerant contained in the
circuit.
SERVICING AND SCRAPPING
In order to repair the refrigerant circuit, the coolant contained within should not be released to the
atmosphere, but it should be recovered and destroyed in treatment plants intended for such purpose.
Considering the fact that the R410A is a mixture, in the event of leakage, the extra refrigerant should be
filled in liquid state. Filling the refrigerant in gaseous state alters its composition and might cause heat
pump malfunctions.
Before dismantling the heat pump, the coolant should be recovered for disposal at a treatment plant, in
accordance with the current regulations.
2.2. HYDRAULIC CIRCUITS
The installation and any further actions on the heating-cooling, brine and DHW circuits should be performed
by authorized personnel only and in accordance with applicable local regulations and following the
instructions provided in this manual.
DANGER!
Avoid touching the pipes, the compressor or other parts of the heating-cooling, brine and DHW
circuits during or immediately after operating the heat pump. These could be at high or low
temperature, and touching them could result in burns from heat or cold. If you need to touch these
parts, allow time for temperatures to stabilize and use protective gloves to prevent injuries.

2.3. ELECTRICAL INSTALLATION
Any action carried out on the electrical installation of the equipment should be performed by an authorized
installer and in accordance with the applicable local regulations and the instructions outlined in this manual.
3. HEAT PUMP OVERVIEW
3.1. MODEL IDENTIFICATION
The range of ecoGEO heat pumps is available in two models, ecoGEO B and ecoGEO C. The ecoGEO C
heat pumps include a built-in DHW tank of 170 litres. The ecoGEO B heat pumps have only the heat pump
module and the DHW tank should be installed separately. Each of this models are available in 9 different
models, depending on the application, the heating output and the type el power supply, as described in
Table 3.1.
ecoGEO B1 and C1 models provide heating and DHW non-simultaneously, using a 3-way valve. In addition,
the ecoGEO B2 and C2 models provide passive cooling option, allowing moderate cooling to the housing
with a minimum consumption of the heat pump (a consumption resulting from circulation pumps only).
ecoGEO B3 and C3 models provide simultaneously DHW and climate control system through cycle reversal.
Each one of the three versions is available for adjustable heating outputs within the ranges 3-12 kW and 5-
22 kW, given the use of inverter compressors. 3-12 kW models are available only with single-phase power
supply, while 5- 22 kW models are available with both single-phase and three-phase power supply.
DANGER!
Before carrying out any operation on the electrical panel, disconnect the power supply.
When the upper front cover of the heat pump is removed, the electrical panel is exposed and its
components could be touched accidentally. During the installation and maintenance of the
equipment, never leave the electrical panel unsupervised while exposed.
Avoid touching any component of the electrical panel with wet hands; otherwise, electric shocks may
occur.
Avoid touching any electrical component of the heat pump (including circulation pumps, valves,
legionella protection electric heater, etc.) either during or immediately after operating the equipment.
Otherwise, fire or electric shocks may occur.
Avoid using water or other liquids for cleaning the heat pump; otherwise, fire or electrical shocks may
occur.

3.2. OPERATING PRINCIPLES
ecoGEO geothermal heat pumps are designed for conditioning (heating and cooling) and providing DHW all-
year round with simple installation and guaranteeing maximum energy efficiency at all times.
Installations with geothermal heat pumps consist of three main circuits (refrigerant circuit, brine circuit and
heating-cooling circuit), in which thermal energy is carried between the ground and the building by using
several fluids (refrigerant, antifreeze mixture and water). These circuits use different fluids; therefore, the
transfer of thermal energy from one fluid to another is done by heat exchangers, where fluid at the highest
temperature transfers heat to the fluid at the lowest temperature without mixing.

The operating modes provided by the different technologies included in the ecoGEO geothermal heat pumps
are outlined below.
HEATING MODE
During the normal operating cycle, heat pumps draw energy from the ground for producing hot water in
the heating system. Its operation can be split into four sub-processes which are repeated on a cyclical
basis.
The antifreeze mixture is successively circulated by a circulation pump through an ground source
system, where it absorbs heat from the ground, and the evaporator, where it transfers heat to the fluid in
1

10 ECOFOREST Geotermia
the refrigerant circuit. The refrigerant in the evaporator is at low pressure and temperature, and it
vaporizes as a result of the heat absorbed by the antifreeze mixture.
The refrigerant vapour coming from the evaporator is suctioned by the variable-speed inverter
compressor, where its pressure and temperature increase (hot gas) in order to meet the actual heating
demand.
The hot gas coming from the compressor is led to the condenser, where it transfers heat to the water in
the heating system. As a result of this heat transfer, the refrigerant gas cools down and condenses into
liquid form.
The refrigerant in liquid state is led back to the evaporator through the electronic expansion valve, which
accurately controls the re-circulated refrigerant flow rate based on the heating system requirements. At
the same time, while passing through the electronic expansion valve, the pressure and the temperature
of the coolant decrease in order to attend again the condition to absorb heat from the antifreeze mixture
in the evaporator.
FREE COOLING MODE (ECOGEO B2 AND C2 MODELS ONLY)
The heat pump is supplied with an extra heat exchanger which allows direct heat exchange between the
brine in the ground source system and the water in the cooling system, so the refrigerant circuit is not
used. By using this operating mode, the compressor remains off and the cooling and brine circuits are
derived to the free cooling heat exchanger through two 3-way valves. Thus, the equipment supplies fresh
water to the cooling system, obtained from the energy exchange with the brine system, all with the sole
use of circulation pumps.
This technology allows to air-condition dwelling (or commercial premises) all-year round in temperate
regions, where temperatures during warmer months do not reach excessively high values. It is worth
mentioning that, in the FREE COOLING mode, energy consumption is very low due to the high efficiency
of circulation pumps.
ACTIVE COOLING MODE (ECOGEO B3 AND C3 MODELS ONLY)
Active cooling consists of reversing the operating cycle of the heat pump's refrigerant circuit through a 4-
way valve. This means that the normal cycle condenser becomes the reversed cycle evaporator, and
vice versa. In this operating mode, the fluid in the cooling system (water) draws heat from the dwelling
and transfers it to the refrigerant in the evaporator; whereas the antifreeze mixture absorbs heat from the
refrigerant in the condenser and transfers it to the ground. This operating mode is called active cooling
by cycle reversing.
This technology provides year-round air-condition for housing (or commercial premises) even in regions
where temperatures reach high values during warmer months.
DHW MODE
The production of domestic hot water (DHW) is performed by two different technologies, depending on
the model. For ecoGEO B1, B2, C1 and C2 models, the production of DHW is done by deviating the hot
water from the condenser into the coil of the DHW tank via a 3-way valve. EcoGEO B3 and C3 models
are equipped with CHW patented technology (Closed Hot Water production system). This new
technology consists of incorporating an additional heat exchanger (desuperheater) intended for DHW
production only. This heat exchanger is placed in series with the main condenser and feeds hot water
into the coil of the DHW tank through a closed circuit. Also, given the fact that cycle reversal is done after
the desuperheater, it allows simultaneous DHW and heating/active cooling production. Therefore, the
CHW system can produce DHW up to 45ºC and also heat it up slowly when the machine is working to
produce heating, cooling or servicing the pool up to 70ºC.

Installation and User Manual. Version V03.B03_EN (23/09/2015) ecoGEO
11 ECOFOREST Geotermia
If the electric support is enabled, the electric resistance works only at the end to heat the DHW up to the
antilegionela setpoint. Therefore the electric resistance is used as little as possible.
LEGIONELLA PROTECTION MODE
The heat pump is equipped with a electric resistance installed in the DHW tank, intended for preventing
potential legionellosis outbreaks only. Once per week, the heat pump increases the storage tank
temperature up to the setpoint temperature, and the electric heater is subsequently activated in order to
increase the DHW temperature up to 65 ºC, i.e., a temperature at which the bacteria cannot survive
more than 20 minutes. It is recommended to carry out the heating during the night, when no DHW is
being consumed.
POOL MODE
The pool mode allows activating an external 3-way valve for deviating the hot water supply from the heat
pump into a heat exchanger through which heat is transferred to the water in the swimming-pool.
FAULT MODE
In the event of heat pump failure, that impedes start the compressor, the electric heater can be activated
for daily DHW production, ensuring DHW production for the user in case of heat pump failure.
