2.3 FUSE

The valve's electronics board incorporates a safety fuse to prevent any damage being caused to
the J10 connection.
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 (5x20).

2.4 PRESSOSTAT ADJUSTMENT.

Use the fi lter or valve manometer as a reference guide when reading the pressure gauge. Proceed
as follows:
1º Turn the pressostat 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 going to the pool until the desired pressure level
is displayed on the manometer.
3º Gently slacken the pressostat screw (1) (APPENDIX 2 – fi g. 1) until the LED on the electronic
board comes on (1) (APPENDIX 3). This LED can be seen throught the transparent cover at the
bottom on the right. After 10 seconds, the pump will stop.
4º IMPORTANT. Open the pool return valve.
5º 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 (0.4 - 0.5 bars). The voltage of the solenoid should be 24 Volts
AC. (See APPENDIX 1 - Fig. 9)
