4. INSTALLATION STEPS
Before starting the installation, check the availability of all the necessary components and
tools:
- Drill
- Screwdriver
- Hydraulic installation components
- Electric installation components
Once it has been checked that it is available all the necessary components and tools, the
installer should follow the next steps:
1. Placing the ECOHEAT
2. Hydraulic installation
3. Air connections
4. Electric installation
5. Commissioning
5. PLACING ECOHEAT
The place where the system will be installed should allow an easy access in order to make
maintenance work or inspection.
Air outlet of ECOHEAT is around 5-10 degrees below inlet temperature, so in case that the
exhaust air would not be ducted, the room temperature will be considerably reduced.
Beside these factors, it is important to take into account the following indications regards the
installation site:
- The system has been designed and manufactured for it indoors utilization. Install the
system in a dry, frost-free room at a minimum temperature of 5 ºC.
- Installer must install the supplied Silent blocks to avoid the transmission of vibration.

6. AIR CONNECTION
Ecoheat unit has two air connections located at the top cover of the system.
There are different installations possibilities:
Since the temperature of the exhaust air is lower than the intake air flow, the user can recover
this cold air to refresh a room. In this case, it is recommended to install a double duct, one to
the room and other to outdoors. Using a gate, the user can stop the air flow conducting it to
outdoors when cooling isn’t needed.
IMPORTANT:
- Do not use flexible duct! Only smooth PVC pipe is allowed.
- Do not use anti-insect grid.
When the inlet and outlet ducting is needed, use only rigid smooth PVC tube.
The pressure drop in the whole air circuit (pipes and accessories) must be lower than the
static pressure of the system, 70 Pa.
In the following table is shown the allowed total pipe length (intake + exhaust). The
equivalent length of any accessory installed in the circuit must be subtract to the maximum
allowed pipe length:
Maximum length (PVC rigid pipe) 160 mm 17 m
Elbow 90º PVC 160 mm 3 equivalent meters
External grid 2 equivalent meters
SUCTION FILTER
The system includes in the air intake a filter for the protection of all the elements of the
refrigeration circuit. This filter should be checked every 6 months to verify that is has not been
clogged. To do this, remove the filter from the suction duck and check if the channels allow
air passage. Otherwise, wash it with water or replace with a new one.
If you notice that the system does no heat up, check the condition of the filter. A clogged
filter affects the life-cycle performance and hot water production of the system.

7. HIDRAULIC CONNECTION
The hydraulic connections are shown in the following scheme:
The installer must install the following components of the hydraulic circuit:
- Cold water inlet (1)
- Ball valves (2)
- Pressure reducing valve (3)
- Non- return valve (4)
- Lined Filter Strainer (Y Type) (5)
- Drain (6)
- Safety valve (7)
- Expansion vessel (8)
- Check valve (9)
- Recirculation pump (10)
- DHW (11)
Once the hydraulic connections are made, vent the circuit to avoid the air inside the
installation.
CONDENSATE DRAIN
The condensation in the evaporator could produce a constant water flow that has to be
drained properly. The condensate drain is located in the back of the system (Figure 4, H).
Connect the condensate drain to the wastewater network making a siphon.
Ensure that water can flow freely.

9.10. Photovoltaic input
Working on this mode, the system automatically heats the water due to electric energy
surplus or by Off Peak rate.
The parameters of this mode can only be changed by the Installer’s Menu.
Contact with the technician for more information.
The system can be combined with and Photovoltaic Inverter to take advantage of the
surplus energy generated by the panels, by forcing the system working and storing this
energy in useful hot water.
The system has in the electric boar two terminals to connect a zero-voltage contact.
When the contact is closed, the system automatically changes to Photovoltaic mode and
the heat pump and electric heater work to achieve the programmed temperature. When
the contact is opened, the system returns to the previous mode.
This contact can be also used for Off Peak Rates. To do it, connect into the contact a timer
with a zero-voltage output.
