6. Attach the Flow Regulator with its plastic lid on top to the end of the hoses. Turn your pump on making sure the Flow
Regulator remains below the water surface. Wait until your pump has removed all air from the hoses and is operating
normally. While the Flow Regulator is under water, observe its setting triangle opening. Adjust your balance between
bottom return and skimmer/dedicated outlet until the triangle's second rib is just visible. Refer to the indicator label on
the Flow Regulator. Skip the next step. If your system cannot provide sufficient flow to the cleaner, as indicated by the
Regulator, it may not clean adequately. You should contact a local pool service company or Hayward Technical Service
for assistance. If you cannot reduce flow to the cleaner, as indicated by the Regulator, go to Step 7.
7. If you cannot adjust flow down to the optimum point on the Flow Regulator, you will need to insert the Regulator in line
with the hoses (without lid). This can be at any point along the flow path from the cleaner to the skimmer/dedicated
outlet but may be initially placed between the third and fourth hoses. The Regulator must remain below the water
surface at all times in order for the cleaner to work properly.
