Remove the Jets

Position the jet tool (provided) with the hook facing up.
Insert the jet tool into the opening of the jet and hook the inside top of the nozzle.
Place your thumb against the whirlpool wall while firmly grasping the jet tool.
Steadily pull the jet tool until the jet assembly pulls free from the housing. Be careful not to lose the
O-ring.
Reinstall the Jets
NOTE: To allow easy rotation and proper operation of the jet, the O-ring must be: (1) correctly positioned,
(2) lubricated, and (3) in good condition.
Install the O-ring onto the first shoulder of the jet.
Using the silicone lube packet (provided), lubricate the O-ring to prevent noisy operation of the jet.
Carefully insert the jet into the housing, then lightly push and rotate the jet until it snaps into
position. Do not force the jet.
Verify the jet is installed correctly. The jet should turn smoothly both clockwise and
counterclockwise. Remove and reinstall, if necessary.
