MAINTENANCE INSTRUCTIONS
Sensor:
The Electronic Sensor is a non serviceable product. If damaged the sensor must be replaced.
−
Turn power off at GPO.
−
Unscrew the two fixing screws. The silicon seal may have to be cut with care to free the sensor.
−
Unplug the solenoid plug and transformer plug from the rear of the sensor. Generally, if the sensor has been
damaged by an electrical surge, it is recommended that the transformer be replaced at the same time.
−
Replace the sensor and reconnect the new sensor. Plug the solenoid and transformer plugs back onto the
rear of the sensor. Fix the sensor panel back onto the galvanised inwall box with the existing screws.
Important: Seal the stainless steel face panel and screws using silicon, ensuring it has a water tight
seal.
Note: Before attempting to replace any of these items check that you have access to re-run the
connection leads. If you do not have access or you have any doubts please contact Galvin Specialised
for advice before commencing replacement.
