Temperature Limit Switch Usage for
Gas Heat Units
Units are factory shipped in the
downflow discharge confriguration but
can be field converted to a horizontal
discharge confriguration. Some, but not
all units require a different TC01 limit
switch, which is attached to the com-
bustion blower motor if horizontal dis-
charge confriguration is used.
Note:
The following units require a limit switch
change out for horizontal discharge. The
additional limit switch is shipped
attached to the blower housing. Refer to
the Horizontal Discharge Conversion,
Step 5 for the following models "ONLY"
YSC060A**H, YSC072A**H, YSC090**H,
YSC102A**H, YSC120A**H.
If any of the above units are installed in
the downflow discharge configuration,
remove the additional TC01 limit switch
from the combustion blower motor and
discard.
