Trane YHC092E - Temperature Limit Switch Usage for Gas Heat Units

Installation
RT-SVX21K-EN 25
Temperature Limit Switch Usage for Gas
Heat Units
Units are factory shipped in the down flow discharge
configuration but can be field converted to a horizontal
discharge configuration. Some, but not all units require a
different TCO1 limit switch, which is attached to the
combustion blower motor if horizontal discharge
configuration is used.
Note: The following units require a limit switch change
out for horizontal discharge. The additional limit
switch is shipped attached to the combustion
blower housing: YSC036E**(M,Y),
YSC036E**(H,Z), YSC048E**(H,Z),
YSC048E**(M,Y) belt drive ID motor,
YSC060E**(H,Z) direct drive ID motor,
YHC047E**(L,X), YHC048E/F**(L,X) direct drive ID
motor, YHC060E/F**(L,X) belt drive ID,
YHC036E**(M,Y), YHC037E**(M,Y), YHC048E/
F**(M,Y), YHC060E/F**(M,Y) direct drive ID motor,
YHC036E**(H,Z), YHC048E/F**(H,Z) belt drive ID
motor, YHC060E/F**(H,Z), YSC072F**(H,Z),
YSC090F**(L,X), YSC092F**(M,Y),
YSC092E**(H,Z), YSC102F**(H,Z),
YSC120F**(M,Y), YSC120F**(H,Z),
YHC092E**(M,Y),YHC092F**(M,Y),
YHC102E**(M,Y), YHC120E**(L,X),
YHC120E**(H,Z).
If any of the aforementioned units are installed in the down
flow discharge configuration, remove the additional TCO1
limit switch from the combustion blower motor and
discard.
