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 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 consider 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. The surface on which
it is to be installed must be able to support the total load of the system.
-As the equipment may cause vibrations or noise, it is recommended to install away from
resting places.
-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. HYDRAULIC 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)
-Recirculation pump (9)
-DHW outlet (10)
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. 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.
