Sealing the TankMaster Unit
The TankMaster control unit is not waterproof and must be installed in a protected environment. In installations where exposure to moisture, dust, or road spray is possible, the enclosure must be properly sealed.
The TankMaster enclosure uses a rabbeted lid design, which requires sealing at specific points to prevent moisture intrusion.
Required Sealing Areas
The following areas must be sealed during installation:
-
Lid perimeter (rabbeted edge)
-
LED openings
-
USB-C power port (with cable installed)
-
Sensor cable entry points (all 4 sensor cables)
Recommended Materials
-
Silicone sealant (automotive or marine-grade)
-
Dielectric grease (optional, for connectors)
Sealing Procedure
1. Install and Prepare
-
Mount the TankMaster in the desired location
-
Ensure all sensor cables and the power cable are connected before sealing
2. Seal the Lid (Rabbetted Edge)
-
Apply a continuous bead of silicone sealant along the rabbeted edge of the enclosure
-
Ensure the sealant forms a complete seal around the perimeter
3. Seal the LED Opening
-
Apply a small amount of sealant over the LED openings
-
Ensure the opening is sealed. Use a clear sealant to allow the LEDs to be viewed
4. Seal the Power Port
-
Insert the USB-C power cable
-
Apply sealant around the cable where it enters the enclosure
-
Ensure a tight seal to prevent moisture ingress
5. Seal Sensor Cable Entry Points
-
Apply sealant around each of the four sensor cable entry points
-
Ensure all gaps are fully sealed
Important Notes
-
Do not seal the unit without all cables installed
-
Ensure the enclosure remains accessible for future maintenance
Best Practice
Whenever possible, install the TankMaster in a dry, protected location, and use sealing as an added layer of protection rather than the primary defense against moisture.
Tip:
Allow sealant to fully cure before exposing the unit to moisture or operating in harsh environments.
