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