INSTALLATION OF THE

JET TECH

LIQUID DETERGENT PUMP

Turning counter-clockwise shortens the injection pulse time as well as increasing the time between pulses. Turning clockwise lengthens the

injection pulse time as well as decreasing the time between pulses.

INSTALLATION OF "NON JET TECH" DETERGENT PUMP

There is power going to the detergent pump wiring harness only when the water fill valve is open: during the fill cycle and during the rinse

cycle, as explained in the previous section. This may be incompatible with some soap systems. Do not make any connections to the timer

as this may cause the machine to malfunction and therefore void the warranty.

DETERGENT PUMP PROBE INSTALLATION

On models F22 and 747, we recommend drilling a hole in the front of the recessed wash tank, 4" from the left side of the recessed wash
tank, as illustrated below.
