Priming The Pump - Cal Spas LTR20111000 Owner's Manual

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.
Using the control panel:
1. Turn the spa on and wait for PR (Priming Mode)
to appear on the topside display.
2. Press the JETS 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 buttons again and let the pump
run in high speed for 10 seconds.
4. Press the JETS button again to turn off the pump.
Using the bleeder valve:
1. Using a Phillips screwdriver, remove the front
panel from the spa and locate the pump.
2. Shut off the power to the spa.
3. Close the gate valve on the discharge side of
the pump.
4. 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.
5. 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.
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.

The pump will not work properly while
air is trapped in it. Continuing to operate
the pump in this way will cause damage.
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.
Note: If you press the Temp button any time
during Priming Mode, it will exit that mode and begin
Standard Mode.
