Priming the pump(s): Upon filling or refilling the spa, if a pump is operating and water is not flowing from any of its jets, the pump may not be properly primed. To correct, perform the following procedures:

•Turn off power to the spa at the breaker and remove the equipment compartment door (as seen on page 24).

•Loosen the union on the top of the pump(s) (as seen on page 24) to allow the air to escape, the hand-tighten the union(s).

•Turn power back on, activate the pump and check to make sure union is tight enough to keep it from leaking. Re-install pump and equipment doors.
