Dometic Sealand External Waste Tank Level Sensor Installation guide

  • Hello! I have read the instruction manual for the Dometic External Waste Tank level sensor. This sensor is designed to detect the level of aqueous solutions inside plastic tanks up to 10mm thick. The manual explains how to establish locations for 3/4-full and full levels and how to install the sensors. I'm ready to answer your questions about this device.
  • What is the maximum thickness of the plastic tank wall the sensor can work with?
    What is the operating voltage of the sensor?
    Does the sensor have a fuse?

1 Installation
1.1 Attaching sensors to waste tank
To establish “3/4” and “full” level sensor locations for each tank model:
1. Fill tank to desired “3/4” level.
2. Connect sensor to tank monitor system and turn electrical power on.
3. With adhesive protective liner still attached, slide sensor against tank wall from top of tank down to approximate
water level. When monitor system activates, the sensor has located the water level. This marks the sensor location for
“3/4” full. Remove adhesive liner and place sensor on tank. Use this same sensor location on all similar model tanks.
4. Fill tank to desired “full” level and repeat steps 2 and 3.

Notes
• Heavy lines represent stranded copper wire.
• All other wire can be 18-gauge stranded copper wire.
• Wire size to determined by:
- RV applications: ANSI/RVIA LV, NFPA 70/NEC
- Marine applications: ABYC recommendations
