SENSOR CLEANING INSTRUCTIONS BEFORE HANDLING
Stingray sensors that have been immersed in sewage should be cleaned before handling.
1. Rinse sensor and cable to remove debris.
2. Immerse sensor and cable in a solution of 1 part household bleach (Javex, Clorox etc.) to 20 parts
water for 5 minutes. Do not immerse open end of sensor cable or cable plug. Ensure that the protective
cap is properly fitted to the cable plug before immersing in water or cleaning solution
3. Remove grease from sensor with clean water and mild soap. Do not use abrasive cleaners, solvents or
high pressure washers.
SENSOR CLEANING WHILE STINGRAY IS IN OPERATION
Use a soft brush or broom to wipe the sensor face. DO NOT USE an abrasive tool or gouge the surfaces
of the sensor.
Remove the sensor from its mounting bracket to remove severe build-up of debris or “stringers”
attached to the sensor, cable or mounting bracket.
