Wash process:
The valve automatically reverses the fi ltration cycle and commences the sand wash process, this
requires that the valve is set so that the water coming from the PUMP connection passes through
the valve and is taken to the fi lter by the BOTTOM connection, the sand is stirred and the water,
together with any accumulated dirt exits the valve TOP connection which communicates with the
WASTE connection and is taken to the drains. This process is carried out in accordance with the
pre-established timing.
Back-wash process:
The valve is positioned to compress the fi lter bed and not to send water containing sand to the
swimming pool, this is achieved by water coming from the PUMP connection entering the fi lter by
the TOP connection, it then compresses the sand and the water enters the valve via the BOTTOM
connection which then sends it to the WASTE connection. This process is carried out in function
of the pre-established time and once it has elapsed, the valve commences the fi ltration process
again.
