Problem:

The red light on the SP-2 Control will not come on so the system will not

run.

Solution:

1. Unplug the control from the wiring harness and connect the wiring

harness together. If the pump does not run, either you do not have a

good connection or are wired to a switched power source and need to

turn on the switch.

2. Unplug the control from the wiring harness and connect the wiring

harness ends together. If the pump runs, but does not pump, check to

see if the pump is blowing bubbles back into the tank. If you see

bubbles in the tank, the system was wired incorrectly at the power

source. Switch the red and black wires around.

Problem:

The system has worked for a while and does not pump any longer.

Solution:

1. Follow the instructions on pages 12 and 13 to replace the pumping

tube. Use the spare tube included in the manual bag. If replacing the

pumping tube, it is recommended to order a spare tube to have on

hand for the next replacement.

2. If you replaced the pumping tube and the pump still does not pump,

you may have to adjust the tension on the Pressure Yoke.

instructions on how to do this, see page 13.
