SEAT AIR HOLE DRILLING
(WHEN OPTIONAL AIR BLOWER IS INSTALLED)
Seat Air Holes
Because the air blower is an optional feature of the Cirrus IG, air holes are not factory drilled in the seating area. Included
with your spa are an air hole drill guide and a 5/32" diameter drill bit with which to drill the 59 holes required. The drill guide
is shaped to fit the contour of the spa. We recommend that you apply masking tape to the underside of the guide to prevent
scratching the spa surface.
Locate the dimples imprinted in the surface of the seat. (The dimples indicate the center of the air channel located beneath
the seat.) Align the drill guide so that it fits the contour of the spa and is positioned against the footwell wall, and the hole
is over one of the dimples.
Insert the drill bit provided into the drill chuck so that only 1" to 1 1/2" of the drill bit extends out of the chuck. With the
drill guide in place, insert the bit into the guide and proceed to drill with light pressure at low speed through the acrylic,
increasing to high speed to drill through the fiberglass. Continue marking and drilling holes around the seat of the spa until
all holes are drilled at 1 3/4" intervals. (See illustration below.)
Use care when drilling! Failure to use the drill guide or drill bit provided may cause the bit to drill through bottom
of the air channel or cause permanent damage to the shell.
