to red AC. If there is not a white jumper wire between J11 & J32. Look on the back side of your control box
there should be a wire taped to the back of the box. If you are running 110v or 220v check which mode you are
in; standard, sleep, or economy. If problem persists please contact your dealer.
Or you might be in "ECONOMY" or "SLEEP" mode, refer to page 15 for mode options. The spa MUST be in
ST,ANDARD mode for continuous heating. If problem persists, please contact your dealer.

wires to GFCI Breaker, and check all wires from GFCI to your control box. Make sure to replace any blown
fuses with a fuse of the exact same type and rating. You may also have a faulty pump, ozonator, or element.
Please contact your dealer.
