TROUBLESHOOTING RETURN SYSTEM PRESSURE
Bubbles upon start-up and shutdown are perfectly normal. If persistent bubbles are present in the pool
and you have
Plumbing Configurations 1 or
2, please complete the following steps:
Step 1:
Switch the system off and install a 2-way valve between the
return manifolds and the auxiliary heater and/or chlorinator cell
(if present).
Step 2:
Switch the system back on, and move to the newly installed 2-
way valve
Step 3:
Constrict flow in the return line using the lever handle by a small
increment.
Step 4:
Wait a few minutes before checking the pool water. If air continues to bubble, constrict flow by another
small increment.
Step 5:
Again, wait a few minutes before checking the pool water. If the air bubbles consistently stop, then the
system should be set at an acceptable positive pressure.
Step 6:
Re-check that the pressure gauge is within the recommended pressure ranges.
Step 7:
Leave the 2-way valve setting in place permanently by removing the handle.
If you have installed a system with
Plumbing Configuration 3: Manual Driver Valve Connection
the
following procedure for adjusting the Three-Way Valve for Manual Systems will need to be carried out:
Step 1:
This process can be done with the vacuum valve’s top, and O-ring removed. However, be careful not to
misplace any components.
Step 2
: Open the three-way ball valve by a small increment using the lever handle.
Step 3:
Wait a few minutes and check if there is air still bubbling out of the return line.
Step 4:
If air bubbles are still present, open the valve by another small increment.
Step 5:
Continue opening the valve by small increments, until the air bubbles reliably stop.
