How do the nozzles rotate?
The nozzles have an offset hole that thrust the nozzle forward while it transitions from the up to down position. Each time the nozzle comes on it is in a new position and cleans a new area of the pool. • Why are there two drains in my pool? Two points of suction are safer than one. Many Municipalities are now requiring two drains for each pump even when it is also tied to a skimmer. • Why should the heater have an external bypass? Even though most heaters come with an internal bypass an external bypass is required to ensure that both heater and in-floor system function properly. The high flows with the in-floor system do not allow efficient transfer of heat in the heater, so a bypass is necessary to slow down the water going over the heat exchanger. The bypass also reduces the restriction on the system. • Do the nozzles need to be set in a specific sequence? The nozzles themselves do not need to be sequenced, as they will not stay in sequence for long. They simply should be plumbed so
