Function<br />
Cast-in electronic water level sensor<br />
automatically monitors quick fill<br />
and safe-off functions<br />
in very shallow water depths.<br />
Sensor is adjustable in height after<br />
installation. Low voltage for safety.<br />
Connects to DEFO ‘ECL’ control<br />
panel (see page 63). Install vertically.<br />
Function<br />
Flush, wall mounted, combination<br />
electronic water level controller and<br />
overflow drain. Automatically monitors<br />
quick fill and safe-off functions,<br />
and drains overflow water through<br />
a built-in drain. Integral adjustments<br />
on level sensors and standpipe<br />
facilitate adjustments after<br />
installation. Low voltage for safety.<br />
Connects to DEFO ‘ECL’ control<br />
panel (see page 63).<br />
