during backwash
When charging proceed as follows:-
!
Disconnect the inlet, outlet and backwash pipes from the Multiport Valve at
the union connectors.
!
Unscrew and remove the Multiport Valve clamp and lift out the valve, which
is sleeved on to an extension from the bottom collector pipes. This pipe
should now be blocked with paper or a cloth to prevent the ingress of media
during charging.
!
Charge with media as per the instructions given above.
!
Replace the Multiport Valve ensuring that both the valve neck and collector
O-rings have first been smeared with petroleum jelly. Note this should be
done whenever the Multiport Valve is removed.
!
It is also important to ensure beforehand that all sand has been removed
from the filter O-ring seat and the O-ring itself to prevent leakage.
Rotate the Multiport Valve to align the outlet ports with the piping and ensure
proper seating. When properly seated the clamp should be secured ensuring
uniform torque but not over tightening of the clamp bolts. If the joint weeps under
pressure, reseat the MPV in a different position ensuring it is properly seated on
the filter neck. Over tightening will damage the filter.
