1.2.5 Recirculation position

In this position, water from the pump flows directly into the pool through the RETURN nozzle after passing
through the valve, thus not passing through the filter.

2. INSTALLATION.

2.1 HYDRAULIC INSTALLATION.

The valve is supplied with the necessary accessories for installation on the side inlet filter.
The specific sheet for the hydraulic connection of the valve to the filter is attached. Please take into account
the following warnings:
- Apply PTFE sealing tape on the male thread elements, avoiding sealing paste under all circumstances.
- The use of 3 piece links between the valve and the rest of the installation is recommended to facilitate
possible maintenance tasks.
- Always install a ball valve in the return pipes to the pool.
- Use a suitable glue for the ABS to glue the elbow supplied for the BOTTOM opening of the valve body.

2.2 ELECTRICAL CONNECTION.

The control module of the automatic valve will always be connected to a control cabinet that will determine
the filtration times of the pool by means of a timer. The minimum components that the control cabinet
must have are: differential (advisable), circuit breaker, pump contactor, position switch (on"II" / high "I")
and programmer clock.
The contactor controls the filtration pump and the valve is connected to the operation of this contactor
in series to the connection coming from the timer in order to stop the pump.
Follow the following instructions in order to prepare the control box and its connection to the electronic
module:
- Power supply: 115-230 Vac. It is advisable to take the current from the control box connect to the "out"
terminal of the differential (if used), or else connect the L, N and T terminals from the magneto thermal
breaker to the corresponding L, N and T terminals of the electronic module. This connection has no polarity.
We recommend that a 3 wire earthed cable of 0.75 mm2 is used (H05VV-F) with a cord diameter of 5 to
6.7 mm (Tightening torque: 1.5 Nm). The cable should meet the specifications for Low Voltage Regulation,
as well as other local regulations.
It is mandatory to install a multiple switch that allow the power failure of the device from the control
box.
It's essential for the valve to have the power supply switched on at all times, to guarantee
that the anti-condensation device works properly.
- Control of the contactor solenoid pump: connect series terminals 4-5 of the valve with the input
connection to the contactor coil A1. The valve will stop the pump when any operation needs to be carried
out. We recommend that a 2 thread cable of 0.75 mm2 is used (H05VV-F) with a cord diameter of 5 to 6.7
mm (Tightening torque: 1.5 Nm). This connection has no polarity.
This connection must be made for the valve's correct functioning, as the electronics detects a minimum
consumption to thus avoid, that the operations are carried out with the pressure pump working which
could damage the valve.
It is important that only the solenoid contactor is connected and that there is no other power source
connected so that 0.4 A are exceeded.
