1. VALVE CHARACTERISTICS
1.1 VERIFICATION OF VALVE TYPE.
Multiport valve, 1½" Model BASIC 115-230 Vac (50-60 Hz); Model 2" BASIC 115-
230 Vac (50-60 Hz). Both the model and code are indicated on a label, together with
the valve operating specifi cations 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 verifi ed 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 justifi ed complaint.

1.2 FLOW DIAGRAM FOR THE VARIOUS VALVE OPERATING POSITIONS.

The valve should be installed in the fi lter following the instructions provided in the
included leafl et.
The valve may be positioned on the side or top of the fi lter, in whichever position is most
comfortable for subsequent use.
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 fi lter.
BOTTOM indicates the lower return from the fi lter to the valve.
RETURN indicates the return from the valve to the swimming pool.
WASTE indicates the connection to the drains.
Introduction to the fi ltration 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 fi lter (TOP). It
passes through the fi lter bed and returns to the valve once again via the BOTTOM con-
nection 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
150 kPa (1.5 bar) (21.3 psi). If this requires further adjustment, it should be set to the
pressure of the installed pump, adjustment range: 30 to 300 kPa (0.3 to 2 bar) (4.2
to 28.4 psi).
If the pressure exceeds the pre-established limit, the valve will automatically change
over to the Backwash position.
This change can also be automatically time controlled, after 7 days of the valve being
connected to the mains supply.
