REMOVE PARTS FOR DE-SCALING
A. Remove the ice thickness and harvest float switch.
Pull forward on the bottom of the bracket until clear of the
tab, then slide bracket upward to remove the bracket and
float switch as an assembly.
NOTE: At this point, the component can easily be cleaned.
If complete removal is desired, follow the wires to the
bulkhead grommet (exit point) in the back wall. Pull the
wire connector through the bulkhead grommet, then
disconnect the wire leads from the connector.
Important
Reversing the mounting location of the ice thickness and
the harvest floats will result in a safety limit 2 failure.
• The ice thickness float must be mounted to the front of
the water trough and the electrical connection must be
in the top bulkhead grommet.
• The harvest float must be mounted to the side of the
water trough and the electrical connection must be in
the bottom bulkhead grommet.
• The wire connectors for each float are different and will
not allow incorrect electrical bulkhead connection.
