Optional Air Blower
Two channels under the seating area of your Cirrus IG receive air from the air blower and distribute the air throughholes
in the seating area (to be drilled according to instructions on the following page). As the pressurized air is released from
the holes, tiny bubbles are formed. These bubbles travel upward through the water and expand until they reach the surface,
whereupon they burst. The visual effect of the bursting bubbles contributes to the overall hydromassage experience.
Consult your Jacuzzi Whirlpool Bath dealer for the air blowers available. The minimum rating of the air blower you use
should be 110 cfm, 2.6 psi. For best performance, the blower you select should not exceed this rating by more than 10
percent. See the illustration on page 8 for its recommended location. A bottom discharge blower should be mounted directly
onto a vertical 2" diameter PVC pipe (see illustration on this page). Side discharge blowers that are installed lower than 12"
above the spa's rim must be plumbed with a loop, as illustrated on this page. Some air blower manufacturers recommend
that a check valve also be installed, but use of a check valve instead of a loop is not recommended. Follow blower
manufacturer's instructions when installing.
CAUTION: Wait 24 hours before turning on the air blower, as the PVC cement fumes remaining in the plumbing
are flammable and may explode when the blower is started.
