2.3 FUSE

The valve's electronics board incorporates a safety fuse to prevent any damage being
caused to the J10 connection (terminals 4 and 5).
As stated in the previous point, incorrect connections or other connected components
which increase power consumption at the connection between the solenoid valve of the
pump contactor and the valve may result in operational faults.
A fuse therefore prevents the consumption through this conductor exceeding 0.4 A, thus
preventing such faults. In the event that the fuse fails, check the electrical installation
to ensure that it matches the electrical diagram before replacing the fuse with a new
one of the same specifi cations.
2.4 PRESSURE SWITCH ADJUSTMENT.
Use the fi lter or valve manometer as a reference guide when reading the pressure gauge.
Proceed as follows:
1º Turn the pressure switch screw (1) (APPENDIX 1 – fi g. 1) until it is fl ush with the
black piece (it is not necessary to tighten it all the way).
2º With the pump running, close the return valve to the swimming pool until you can
read on the manometer the maximum pressure you wish the equipment to be run
on. This point is the pressure value at which the valve will start the backwash and
rinse process of the fi lter.
3º Gently loosen the screw (1) (ANNEX 1 - Fig. 1) of the pressure switch until the green
LED backwash button light of the control panel comes on (see chapter 4.1 of this
manual).
After approximately 7 seconds, the pump will stop and start the wash routine.
4º IMPORTANT. Open the pool return valve.
The pool's return tube has to be equipped with a ball valve to ensure a correct adjustment.

2.5 DRAINAGE SAFETY.

The valve comes ready to be installed in an electrovalve in the drainage circuit. Its use
is recommended in order to avoid water loss in case the electric fl ow is insuffi cient and
the valve ends up in a position that could lead to the pool emptying. The electrovalve
used should have as low a pump pressure orifi ce as possible, maximum 40 - 50 kPa
(0.4 - 0.5 bar). The voltage of the solenoid should be 24 Vac (See APPENDIX 1 - Fig. 9).
