Safety valve loaded at 3 bar (pressure gauge).
Drain valve.
Installation instructions
Follow the instructions below to wire the brine 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.
Check that the volume of the expansion vessel integrated in the heat pump is capable of absorbing any overpressures from
the circuit. If this volume is not enough, install a supplementary external expansion vessel.
If necessary, adjust the pressure of the expansion vessel integrated in the heat pump to guarantee that the circuit remains
pressurised at all points.
3.3. Heating / Cooling circuit
The ecoGEO heat pumps can be connected to various types of heating / cooling systems, both directly and by separating buffer
storage tanks. On the other hand, these enable control over several devices that are external to the heating / cooling system directly
from the heat pump's electrical panel.
Heating / cooling system
The ecoGEO heat pumps are designed to be used with heating systems with nominal outlet temperatures of up to 55ºC; such as
underfloor heating systems, low temperature radiators or convectors. They are not recommended for use in heating systems that
require higher temperatures.
The ecoGEO heat pumps can be used with cooling systems with nominal outlet temperatures of up to 7ºC, such as convectors and
underfloor cooling systems.
Special care should be taken in the design and control in installations with underfloor cooling, to prevent problems of condensation
on floors.
The models that are not equipped with integrated passive cold allow control of external passive cooling equipment.
Direct installation
In simple heating / cooling systems, ecoGEO heat pumps can be installed directly into the distribution system, in systems with
underfloor heating, low temperature radiators and convectors.
