Uniform regeneration
The special design of the support grid's bottom causes a great turbulence at the lower area in the filter that
makes the paste easy to homogenize as well as it causes a quick and uniform distribution all over the gids
area. From all that, a longer cycle an better filtration are achieved (See Fig.4).
3.-COMPONENTS
1. Filter.
2. Special D.E. Multiport valve, with fittings.
3. Valve gaskets.
4. Air relief system and pressure gauge.
5. Filter instruction manual.
6. Multiport valve installation manual.
4.-INSTALLATION
Place filter on a flat surface as close as possible to the pump, under water level, and provide protection
when freezing weather, supply an outlet pipe to drain filter. Let enough space to filter disassembly ( see
<<TECHNICAL CHARACTERISTICS>>).
If possible, connect filter to 2" pipes and install isolation valves on both sides of the filter to allow for easy
valve and filter servicing.
Install multiport valve by following its instructions manual. Connect pipes as indicated in valve ports.
The multiport valve allows you to operate the 6 following functions: (see fig.5)
Filtration: This is the operation normal position. Water from pump enters the filter and returns to the pool
after been filtered.
Waste: Pump drives water directly to drain, without going through the filter. It is used to partially drain the
pool.
Closed: All inlet and outlet ports will be closed when setting this position. It is used for filter maintenance.
Never start pump while valve is in this position.
Backwash: Water runs through the filter on the opposite filter's direction and is drained. It is used to clean
the filter by removing the D.E and dirt.
Recirculation: water is running through the installation without going through the filter.
Rinse: Water runs through filter in normal direction and it is drained. This position is used after Backwas
to avoid dirty water going back to pool.
NEVER OPERATE MULTIPORT VALVE OR DISASSEMBLE FILTER WITHOUTTURNING OFF PUMP.
NOTICE: Make sure that waste water disposal complies with local codes and ordinances. Provide a D.E.
Separations tank, if necessary.
