Place the universal adapter into the dedicated suction line, if your pool has one. Attach one of the hose sections to the adapter. If using a skimmer, insert the adapter into the suction line in the skimmer. Push the flow regulator into the adapter. Feed one of the hose sections into the skimmer opening and connect it to the flow regulator.
Connect the hose sections, except for the leader hose and standard hose, by pushing the cuffs together. Connect the standard hose to the end of one hose and attach the leader to the same end. Attach the assembled hoses to the hose section already installed on the skimmer or suction line.
Connect the leader hose to the Polaris pool cleaner hose connection.
Extend the assembled hose to the farthest section of your pool. The hose must reach two to three hose sections beyond the farthest point to allow for slack. Adjust the hose length by removing unneeded sections.
Detach the hose and flow regulator to test the water flow. Submerge the hose to fill it with water. Reattach the hose and flow regulator and connect the flow indicator to the leader hose. Hold the indicator underwater while turning on the pump. The flow indicator shows if the water flow range is correct or too slow or fast.
