Use of this float on a tank other than the one it was custom designed for or in a product other than the one it was designed for, may provide inaccurate results. When properly installed, the float must never contact the bottom of the tank and not rest against the side of the drop tube.
THE POWER comes from a solar cell, and is intended for outdoor use. Indoor light may not provide adequate light for the solar cell. If you have an indoor location where you wish to use the gauge, or an outdoor location with inadequate light, please contact your distributor or Greenleaf Gauge, Inc. for more information on our product made specifically for the low light conditions.
