DRAIN
The drain should be checked before initial start-up and
at the beginning of each cooling season to assure that
the lines are clear. If it is clogged, steps should be taken
to clear the debris so that condensate will ow easily.
Periodic checks of the drain should be made during the
cooling season to maintain a free owing condensate.
CONDENSATE FLOAT SWITCH INSTALLATION

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 the down position.
Sensitivity may be adjusted by threading switch
assembly downward out of bracket if necessary.
Test switch by lifting oat with unit on. Unit should
stop running if switch is correctly wired. Test switch
sensitivity by lling pan and conrm switch stops unit
before pan overows.

Should the growth of algae and/or bacteria be a
concern, consult an air conditioning and refrigeration
supply organization familiar with local conditions for
chemicals available to control these agents. If cleaners
are used, they should be compatible with the materials
of construction for the coil and drain pan.
