The optional Tank Level sensor allows even greater control of your ship
’
s fresh water systems. This
unique level monitoring system requires no holes to be drilled into your tank while measuring tank
volume with greater accuracy than a standard resistive float.
Turn off the ship
’
s domestic water system, close the fresh water supply valve at the water tank,
then bleed off the pressure by opening a tap in the galley or head sink.
Install a tee in the
water supply hose at the bottom of the tank, or at inlet to the domestic water
pump
. Connect open leg of the tee to the Tank Level Sensor. Note: The tank level sensor requires
a
1/4”
npt connection. We recommend installing a minimum
1/2”
tee, and using a reducing
bushing to connect the sensor.

If a 2nd Tank Level Sensor is going to be installed, it should be installed at the base of the
second tank.
If monitoring 2 water tanks, they must be isolated from each other with a
valve to read properly.
The wiring connections for the second Tank Level Sensor are located inside the Spectra
Connect control box.
See System Settings section of this manual for instructions on enabling
the second Tank Level Sensor.
See the Tank Level Calibration (pg. 28) in the Commissioning section of this manual.
Optional Tank Level Sensor Installation
Route the 3 conductor cable back to the Spectra Connect control board at the feed pump
module. Extend the wires as necessary.
If you must extend the wires beyond
50’
contact the
factory to ensure proper operation.
Connect the Tank Level Sensor cables to the 3 conductors label Tank Level Sensors at the feed
pump module.
Polarity must be maintained!
