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
valves 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:
Waste:
Closed:
Backwash:
Recirculation: Water is running through the installation without going through the filter.
Rinse:
NEVER OPERATE MULTIPORT VALVE OR DISASSEMBLE FILTER WITHOUT TURNING OFF PUMP.
NOTICE: Make sure that waste water disposal complies with local codes and ordinances. Provide a D.E.
separation tank, if necessary.
This is the operation normal position. Water from pump enters the filter and
returns to the pool after been filtered.
Pump drives water directly to drain, without going thought the filter. It is used to
partially drain the pool.
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.
Water is running 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.
Water runs through filter in normal direction and it is drained. This position is used
after Backwash to avoid dirty water going back to pool.
