Page 5: General Information
Technical manual ecoGEO+ HP 1. General Information ▪ This manual contains the necessary information to install the heat pump. Read this manual carefully before installing the equipment. Keep this manual handy for future reference. This manual contains two different kinds of warnings that should be heeded. ▪...
Page 6 Refrigerant Ecoforest heat pumps may contain different types of refrigerants depending on the model. The refrigerants used by Ecoforest are not harmful to the environment as they do not contain chlorine and therefore do not contribute to the destruction of the ozone layer.
Page 7 Do not apply a flame until the circuit is completely empty. ▪ ake sure that any replacement components in the refrigerant circuit or the heat pump are supplied or approved by Ecoforest. Other parts may result in the ignition of refrigerant in the atmosphere from a leak. ▪...
Page 8 If the problem cannot be corrected immediately, but it is nonetheless necessary to continue with the operation, a suitable temporary solution, agreed with Ecoforest's technical department, must be used. This must be reported to the owner of the equipment so that all parties can be informed.
Page 9 Technical manual ecoGEO+ HP Observe the following warnings during the recovery and charging processes: ▪ hen transferring refrigerant to recovery cylinders, make sure that only suitable refrigerant DANGER! recovery cylinders are used. Make sure that the correct number of cylinders are available to hold the total system charge.
Page 10 Technical manual ecoGEO+ HP ▪ he system must be tested for leaks when charging has been completed but before start-up. A leak DANGER! test should be carried out before the equipment is left to operate normally. ▪ ealed electrical and intrinsically safe components must be replaced when broken or faulty. Hydraulic installation 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.
Page 11 DANGER! ▪ he heat pump must be supplied with an external switch that can shut off all the circuits. Ecoforest recommend installing one external automatic breaker in each external power supply that provide full disconnection under overvoltage category III (control, internal auxiliary equipment and drive).
Page 12: Disposal
The heat pump contains refrigerant. Ecoforest uses refrigerants that are not harmful to the environment, but once their useful life cycle is over, the refrigerant must be recovered so that it can be recycled or disposed of in accordance with current regulations.

Page 16: Recommended Positioning
Technical manual ecoGEO+ HP 2.5. Recommended positioning ▪ he ecoGEO HP heat pumps range must be installed in a place where they are not accessible to the DANGER! general public. Choose a dry place where there is no risk of frost. Avoid installation against bedroom walls or walls of other rooms where noise emissions can be annoying.
Page 17 Technical manual ecoGEO+ HP Description Distances (mm) Minimum distance from the lower ventilation of the technical room to the evacuation in the heat pump. > 0 Minimum height of the lower ventilation of the technical room to the floor. 20 - 100 Maximum height of the lower ventilation of the technical room to the floor Minimum height of the lower ventilation of the technical room to the floor.
Page 18 Technical manual ecoGEO+ HP ▪ For mechanical ventilation, the lower edge of the openings that extract air from the machine room must not be more than 100 mm above the floor. The R454B refrigerant has a higher density than air, so an opening must be installed above the evacuation, so that fresh air enters and mixes with the refrigerant evacuated from the unit.
Page 19: Service Areas

Technical manual ecoGEO+ HP Figure 3.1. Source circuit connection options. Installation instructions Follow the instructions below to wire the source circuit. ▪ Install the necessary components to carry out the filling/discharge of the return pipe. ▪ Install a particulate filter in the return pipe with a mesh size no greater than 1 mm. It is recommended to install shut off valves immediately before and after the filter to make it easier to clean or replace.
Page 22 Technical manual ecoGEO+ HP situation in the emission system. For this, the installation can be planned to operate with at least one of the emission circuits open continuously. If all the emission circuits can be closed, it is recommended to install a differential pressure valve between the outlet and inlet pipes of the heat pump.

Page 27: Filling And Discharge Circuits
Technical manual ecoGEO+ HP 4. Filling and discharge circuits ▪ uring filling work on the hydraulic circuits, take special care to prevent liquid from spilling on the DANGER! internal electrical heat pump components, which could cause personal injury due to electrocution and/or poor equipment operation.
Page 28 Technical manual ecoGEO+ HP Figure 4.1. Filling the source circuit.
Page 29: Electrical System
Technical manual ecoGEO+ HP 5. Electrical system ▪ efore performing any operation on the electrical panel, disconnect the power supply. DANGER! ▪ emember that the heat pump has more than one electrical power supply. ▪ coforest recommends that an external switch be installed for each of the electrical power sources (control, internal auxiliary equipment, and inverter).
Page 30 Technical manual ecoGEO+ HP Several installation devices are controlled from the heat pump electrical panel. Some are internal and other are installed externally. The internal components are connected to the electrical panel in the factory. Depending on the installation that the heat pump is going to be connected to, in addition to the power supply, it may be necessary to connect various temperature probes (analogue inputs AIxx), control signals from thermostats or other external equipment (digital inputs DIxx) on/off switching of pumps and/or valves (digital outputs DOxx) or regulation of pumps and/or valves (analogue outputs AOxx).
Page 31 Technical manual ecoGEO+ HP Analogue inputs (AIxx) These terminals are used to connect external temperature probes. Only passive NTC temperature probes can be connected, so cable connection polarity is not important. If necessary, use extension cables with a maximum length of 50 m and a minimum diameter of 0,75 mm .
Page 32 Technical manual ecoGEO+ HP 24Vac Figure 5.5. Example of digital input connections with 24Vac voltage. Analogue outputs (AOxx) These terminals send analogue 0-10Vdc regulation signals to modulate the control of outlet units with mixture, aerothermal source units with variable speed fan, external auxiliary boilers, etc. On the other hand, these connectors have a 24Vac power supply terminal to supply the modulating valve motor.
Page 33: Heat Pump Power Supply
III (control, internal auxiliary equipment and drive). Ecoforest ecoGEO+ HP heat pumps require two power supply points. One for the power supply of the control panel; this unit includes the power supply of the internal and external valves and also that of the regulation signals and the digital and analogue inputs. The other power supply is exclusively dedicated to the compressor.
Page 34 Technical manual ecoGEO+ HP To carry out the electrical installation, insert the power cables through the cable grommet holes at the back of the heat pump. Continue by connecting the cables to the power terminal block of the heat pump, as described in figures 5.9 and 5.10.
