5. PLACING ECOFLEX
The place where the system will be installed should allow an easy access to make maintenance
work or inspection.
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.
-In case the system has to be placed outdoors, it must be protected against the adverse
weather conditions (direct solar radiation, rain, snow…)
-Try to place ECOFLEX as near as possible of the buffer tank.
-Installer must install the supplied Silent blocks to avoid the transmission of vibration.
The equipment allows the installation on floor or on wall. To do this, it has 4 holes to insert the
legs (supplied) or the supports to the brackets.

If the equipment is to be installed in the wall, be aware that a minimum distance between the
water outlet of the tank and the outlet of ECOFLEX must be observed to ensure a good
functioning of the pump and the equipment.
Figure 7. Minimum distance from ECOFLEX to the water outlet of the buffer tank.
6. AIR CONNECTION
ECOFLEX unit has two air connections located at the top cover of the system.
Figure 8. Outlet/intake air
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.

INSTALLATION AND USER MANUAL

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
14 m
Elbow 90º PVC 160 mm
3 equivalent meters
External grid
3 equivalent meters
7. HIDRAULIC CONNECTION
The hydraulic connection depends on the existing buffer tank, if some type of connection for
the recirculation or coil is available.
The possible connections are detailed as follows:

The installer must install the following components of the hydraulic circuit:
- ECOFLEX (1)
- Gate valve (2)
- Check Valve (3)
- Inclined filter (4)
- Expansion vessel (5)
- Safety valve (6)
- Storage tank (7)
- Pump (8)
- Pressure gauge (9)
- Red water inlet (E)
- DHW output (S)
- Inlet water filled coil (R)
- Probe connection (T)

Once the hydraulic connections are made, purge the circuit to remove the air from the
installation.
In addition, it is necessary to install electrolytic sleeves in the water connections to prevent
galvanic corrosion in the pipes.
IMPORTANT:
- The water pipes must be at least 22 mm in diameter to avoid excessive losses in the circuit
- If the unit is to be installed on the wall, its height must not exceed half the storage tank.
7.1. Pump connection
For the choice of the pump, it is necessary to consider the pressure drop of the installed
pipe as well as the accessories (elbows, filters, valves ...). The following table shows the flow
rate to be circulated by the equipment and the pressure drop of the installed heat
exchanger:
7.2. Temperature probe connection
The equipment incorporates connected temperature probe. The installer must pass through
the indicated opening (Figure 4, G) and connect it to the buffer tank. The position of the
probe varies according to the type of buffer tank.
Follow the instructions in of the diagrams shown in Figures 9, 10 and 11.

The installer must connect the electrical connection of the pump to the terminal block inside
the ECOFLEX unit, as shown in the diagram above.
IMPORTANT: It is only permitted to connect a pump with a power supply of 230 V /1 ph/
50 Hz and 3 A maximum current.
8.2. Electrical heater
It is possible to control the operation of an electrical heater installed inside the tank. To do
this, the installer must connect the power supply to the controller through the terminals R.
IMPORTANT: It is only allowed to connect an electrical heater of 230 V/ 1ph /50 Hz and
1500 W maximum power.
