6600-169 Sundance Temperature Sensor with 50 ft. Cable for Inground Spas

The Temp Sensors are located in the filter compartment on the side. They are unscrewed from the inside of the tub and the wire is fed through the tub over to the equipment compartment. Follow the wire to the PC Board. To feed the new sensor, we usually drain the tub below the hole and pull the old sensor out a couple of feet into the tub, cutting the old sensor head off, we tie on the new sensor (connector end) to the old wire and pull the wire through into the equipment compartment.

On inground equipment, this can be a long pull and may need a wire puller. We have seen ingrounds plumbed where the sensor will not come out.

The connectors on the Temp Sensor are attached to a pc board connector that is located on the PC Board (usually at the top). There are other wires connected to this plug: Jumper interlock wire,Flow Switch, High Limit and Temp sensor. Remove the pin connector from the board . To remove a sensor or switch wire from the sensor harness connector, insert a paper clip into the slot corresponding with the wire to be removed. This will depress the pin tine, allowing the wire to be pulled from the harness connector.

Important! When reinstalling the sensor or switch wire back into the sensor harness connector, make sure the pin tine is lifted (approx. 1/32") prior to inserting the wire. This will insure the sensor wire locks into the harness connector. Do not over bend the pin tine or it may break off. The connectors on the Flow Switch are attached to a pc board connector that is located on the PC Board (usually at the top).
