ERROR CONDITION

This unit has an error code system built in. The small light
located on the front right side of the unit will indicate:

1 Blink – Pressure switch value too low (under 20 PSI)

2 Blinks – Pressure switch value too high (over 70 PSI)

3 Blinks – Maximum run time exceeded (20 minutes)

To correct any of these modes, cycle power off for at least 10
seconds, then turn back on. The control will not work on pumps
where the switch value is at or below 20 psi or above 70 psi.

PRODUCT WARRANTY

One Year Limited Warranty is available on request.
Opening the unit voids the warranty.

Note:

The wiring diagrams are offered for reference. Position

of the pump, control and power supply wires and hoses
should be placed so as not to interfere with any components
for operation of the vessel.
