mounting location.
NOTICE: Any plumbing fixture connected to the tank should not be operated once
the full tank light on the indicator panel is activated.
This section describes how to install the level sensor and indicator panel.
6.1 Installing the indicator panel
1. Identify a mounting location for the indicator panel that is away from direct
contact with water or oil.
