1. VALVE INSTALLATION

1.1 VERIFICATION OF VALVE TYPE

Multiport valve, 1½" Model 24 Vdc Model 2" 24 Vdc
Both the model and code are indicated on a label, together with the valve operating
specifications and the label itself is located on the rear section of the electronic module cover
which is installed on the valve.
Valve hydraulic and electrical operation are verified before it leaves the factory.
It is recommended that before carrying out the installation, a visual inspection be performed
in case any knocks were received which could have damaged the valve.
The valve will be replaced in any justified complaint.

1.2 GUARANTEES.

The valves leave the factory in a fully tested condition, which enables us to guarantee operation.
The guarantee will be effective provided that the installation has been correctly carried out
and this requires that the actual installation operation be performed by a person with the
necessary qualifications for this type of work.

1.3 FLOW DIAGRAM FOR THE VARIOUS VALVE OPERATING POSITIONS.

The valve should be installed in the filter following the instructions provided in the included
leaflet.
The valve must not be installed in the inverted position.
The valve should be installed on the left side of the filter in order to facilitate communication
with the remote control.
Installation under load, the maximum water column that can be supported by the pump is six
metres (19.68 ft).
The hydraulic connections for correct operation are made by following the markings on the
valve itself.
PUMP indicates the connection coming from the pump.
TOP indicates the upper input to the filter.
BOTTOM indicates the lower return from the filter to the valve.
RETURN indicates the return from the valve to the swimming pool.
WASTE indicates the connection to the drains.
Introduction to the filtration process operation:
The pump sucks water from the swimming pool via the skimmer, bottom cleaner or drain, it is
taken to the multiport valve (PUMP connection) and from here to the filter (TOP). It passes
through the filter bed and returns to the valve once again via the BOTTOM connection and is
taken back to the swimming pool by means of the RETURN connection.
The valve includes a pressure switch which is factory set to an operating pressure of 1.5kg/cm 2
(21.3 psi). If this requires further adjustment, it should be set to the pressure of the installed
pump, adjustment range: 0.3 to 2 kg/cm 2 (4.2-28.4 psi). According to requirements, it can be
2
installed with an adjustment of between 1 and 6 kg/cm (14.22-85.3 psi).
If the pressure exceeds the pre-established limit, the valve will automatically changeover to
the Backwash position.
