Temperature Limit Switch Usage
Units are factory shipped in the downflow discharge
configuration but can be field converted to a horizontal
discharge configuration. Some, but not all units require a
different TCO1 limit switch, attached to the combustion
blower motor (6 to 12.5 tons) or to the installed TCO1 limit
switch (15 to 25 tons) if a horizontal discharge configuration
is used.
If any of the units are installed in the downflow discharge
configuration and have the alternate TCO1 limit switch
provided, remove the additional TCO1 limit switch attached
to the combustion blower motor (6 to 12.5 tons) or to the
installed TCO1 limit switch (15 to 25 tons) and discard.
For detailed instructions, refer to “TCO1 Instructions,” p.
37.
