Condensate Float Switch Installation (For
Use With Drain Pan - With Drain Hose Con-
nection)
Ensure oat switch assembly is rmly secured to
the bracket. Ensure top of oat is below rim of pan.
Switch will trip when the water level reaches a point
even with top of oat when oat is in down position.
Sensitivity may be adjusted by threading switch as-
sembly downward out of bracket if necessary.
Test switch by measuring continuity between wires
when the oat switch is down (in its resting position).
Continue measuring for continuity between wires
while lifting the oating switch and observing an open
circuit (loss of continuity). Test switch sensitivity by
lling pan and conrm switch stops unit before pan
overows.

sitivity may be adjusted by threading switch assembly
downward out of bracket if necessary.
5. Ensure wiring matches the wiring diagram provided
with the unit.
6. Test switch by measuring continuity between wires
when the oat switch is down (in its resting position).
Continue measuring for continuity between wires
while lifting the oating switch and observing an open
circuit (loss of continuity).
7. Test switch sensitivity. Fill pan and conrm that
switch stops unit before pan overows.
8. Place warning sticker on air handler or condenser
