Bleeding Air from the Pump

If you have tried priming the pump several times unsuccessfully
using the control panel, you can bleed the air from the pump
manually.
1. Shut off power to the spa.
2. Using a Phillips head screwdriver, remove the front panel
from the spa and locate the pump.
3. Close the gate valve on the discharge side of the pump (if your
spa is installed with one.)
4. Turn the bleeder valve counter clockwise with a small pair of
pliers until the air has been released from the pump.
5. If this is unsuccessful, loosen the Union nut on the side of the
pump with channel locks. When air is bled out tighten the
nut.
6. Turn on power to the spa and press the JETS button If there is
still air trapped in the pump, repeat steps 2 through 5 until the
pump primes.
