Fit each breathing tube between two retainer hoops. The breathing
tubes have been attached correctly when the springs on the
nozzles are under tension.
The breathing tubes must be secured by the hoops to prevent them
being dislodged from the spring-loaded fittings by the force of the
water pressure during the cleaning process.
Arrange the breathing tubes parallel to each other along the spiral.
The breathing tubes must not hang down through the spiral as
water would remain in the folds.
