Trident Test Procedure & Service Checks

Wet Tank Test:
•
Commence filling the tank with water then:
•
Check the pump operates when water makes closed circuit at the Common and
Low Water Level Sensor probes.
•
Check for voltage drop (must be less than 9 Volt) across the Common (black)
Water Sensor probe and the Low Water Level (white) probe.
•
Check that the water doesn't overflow out the drain tube before the water reaches
the High Water Level Sensor.
•
Check for voltage drop (must be less than 9 Volt) across the Common (black)
Water Sensor probe and the High Water Level (red) probe.
Refer to diagrams on pages 75 and 76.
If voltage doesn't drop below 9 Volts:
•
Check for coating on the Water Sensor probes preventing circuit.
•
Check for high water quality (not able to make circuit - refer to Brivis).
