Float Switches
– Float switches are provided to help prevent
unintended energizing of the heating elements. It is vital that the
heating elements be immersed in liquid prior to energizing them.
Failure to immerse the heating elements will cause them to fail and
potentially cause a fire! Wire from the float switch to the terminal
block shown in the panel above. Wire to terminal 1 and 2 on the
float switch. Polarity is not important. Use suitable 2 wire cable (18
gauge recommended) for connection. If jumper wires are installed
in the panel remove them when you install the switch wires.
When wiring the float switches to the control panel use a continuity
tester on the leads to ensure that the switch is open when in the
down (empty) position, and is closed (has continuity) in the up (full)
position. At that time wire to the panel.
CAUTION:
The low water level switches are a backup to an unintended energizing of the heaters. They are NOT intended to
be normal shutoff switches and solely relied upon to keep the heaters from unintentionally
energizing! Dry-fired heating elements are not covered under warranty!
WARNING - DO NOT twist the float
switch apart. This is NOT covered
under warranty.
The indent should be pointed up
for proper float switch operation.
