Royal Fiberglass Pools, Inc. Spas standard plumbing package comes with two (2) air controls.  These two air controls will be located on both sides of the spa and will serve air for the three jets in the series for that side of the spa.  Air controls can be added so that each jet location can operate each jet or as in the standard package, operate a series of jets.

If brick coping or cantilever decking is indicated on the spa order form, the two (2) standard air controls will be installed at the location as indicated on the order form or at the best determined factory location based on additional controls being purchased.  The air supply pipe will be stubbed from the air line behind the spa's coping above the water level.  The air controls will be shipped separate and lightly attached to the stubbed nipple.  Each builder can determine the safest way of mounting the air controls in or on the deck or coping.  If brick or cantilever is not used and the fiberglass spa coping will be exposed, then the air control will be mounted to the coping, either at the desired location or best-determined location.

If an air blower is indicated on the spa order form, Royal Fiberglass Pools, Inc. will not install any factory air controls unless otherwise noted.  The air line will be connected to the jets in the series and will be stubbed 1½" for coupling back to the equipment pad.
