7. Starting at the location above the handle, feed the
Bubble Tubing through the 4 support rings. The blue
stripe should be on the bottom side and the ends of
the tubing should meet in the center of the starting
space above the handle location.
8. Slide a Hose Clamp onto each end of the Bubble Tube
as shown in Figure 3. Install with the bolt on the
underside of the Bubble Tube and facing outward.
Note: The check valve assembly is shipped with a 3/8” barb fitting
installed. If you need to change it to ½”, remove the 3/8” barb and
install the provided ½” barb fitting.
9. Insert the barbed Tee fitting into the ends of the
Bubble Tubing. You will likely need to grip both ends of
the tubing and “wiggle” it onto the Tee. Make sure
that the Bubble Tubing is fully seated onto both sides
of the Tee and the Tee is pointed slightly downward
and toward the center of the base.
10. Tighten the hose clamps securely.
11. The DB36-B will accept a 3/8” or 1/2” airline. Position
the Strain Relief Clamp so that the appropriate size
notch is facing up.
12. Slide the airline through the Clamp and underneath the
Support Arm Assembly.
13. Install a hose clamp onto the end of the airline
14. Connect the airline to the barb fitting
15. Tighten the hose clamp.
16. Install the 2 remaining Carriage Bolts and Nuts through
the Strain Relief Clamp and tighten securely.
Note: The ¼” hole located at the top-center of the Upper Support
arm is for attaching a marker/float, if installed.
