POSITION 5: WASTE
If the swimming pool needs to be drained, the multiport valve must
be in this position.
When draining, the main drain valve is fully open, for the pump to
have sufficient suction. On the other hand, the skimmer valves and
the bottom cleaner valves must be closed in order to avoid air
suction.
POSITION 6
:
CLOSED
This position is for closing off the water from the filter to the pump
and it is used when opening the pump strainer or for installation
maintenance.
4.
START-UP
When the filter has been loaded with filtration media, it must be washed for 4 minutes.
Proceed with the backwash as mentioned (see Chapter 3 “OPERATION PROCESS”).
When this has been done, the filter will be ready to operate.
IMPORTANT: The pump should be switched off when changing the position of the multiport
valve.
POSITION 4: RECIRCULATE
In this position, the multiport valve allows the water from the pump
to go directly to the swimming pool without passing through the
inside of the filter.
