The back of the SPU has three input/output jacks:
1. PROBE - accepts the phone plug from the sensor probe.
2. BOOSTER - accepts the locking connection from the Optional Booster
Patch Cable. This connection is used only in the event of interference with
the radio frequency link between the Booster and the SPU.
3. HEADPHONES - accepts headphone jack. The speaker in the unit shuts
off when headphones are plugged in.
The Power Booster:
This 3” x 6” x 1-1/2” black plastic box contains the AA batteries and circuitry re-
quired to provide an appropriate voltage between the pool water and ground. To
protect the unit and the internal antenna the booster should be kept in the foam
lined case.
The power booster has two input/output jacks:
1. Red - accepts the banana plug connector from the red
Ground Cable.
2. Black - accepts the banana plug connector from the Input
Float Cable.
A toggle switch turns the Booster on ( I ) and off ( 0 ). A LED indicator lights
when the unit is communicating with the SPU. To conserve batteries, the
Booster will turn off automatically when it does not receive a signal from the
SPU for one minute. To re-set the connection flip the toggle to off then on again.
Although the unit reverts to a “sleep” mode when the SPU is turned off, the
toggle switch should be moved to the off position for storage and transport to
conserve batteries.
The Sensor Probe:
This “T” shaped PVC assembly picks up the electrical current flow from the water.
The probe attaches to a standard telescoping pole to allow surveying all parts of
the pool. Twenty feet of wire extends from the probe to the phono plug.
Probe extension caps cover the ends of the probe to reduce random signal read-
ing that result from water flow over the electrodes.
