2.11 Priming the Pump
New spa owners often have difficulty the first time they start their spa and the pump fails to prime. This can be
frustrating, but these simple instructions can help you.
Sometimes air can become trapped in the pump while filling the spa. You will know this has happened when
after you have filled and started the spa, the pump does not seem to function. You will hear the pump operating,
but no water will be moving.
There are two methods of priming the pump.
The first method will remove small air bubbles trapped in the pump.
1. Turn the spa on and wait for PR (Priming Mode) to appear on the topside display.
2. Press the JETS 1 button to turn on the pump and let it run for 10 seconds. The pump should be running in
low speed.
3. Press the JETS 1 buttons again and let the pump run in high speed for 10 seconds.
4. Press the JETS 1 button again to turn off the pump. The pump should be left in the off position for 10 to 15
seconds.
5. Repeat steps 1 through 4 until water is flowing through all the jets and all air is removed from the plumbing.
The second method will remove a large air lock within the pump.
1. Using a Phillips screwdriver, remove the front panel from the spa and locate the pump.
2. While the spa is operating, turn the bleeder valve counter clockwise with a small pair of pliers or a flat head
screwdriver until the air has been released from the pump.
3. If this is unsuccessful, loosen the white union nut on side of the pump with channel locks. When air is bled
out, tighten the nut and set the pump on high speed.
NOTE: The pump will not work properly while air is trapped in it. Continuing to operate the pump in this
way will cause damage.
Whenever you fill your spa, fill it through the filter canister and make sure all jets are open.
NOTE: If you press the TEMP button any time during Priming Mode, it will exit that mode and begin
Standard Mode.
