American Standard TWE060A***E Heat Pump User Manual


 
TWE-SVX03C-EN 5
General
This manual covers installation of
the TWE050, 060, 075, 090,100 and
120A single circuit air handlers and
TWE060, 075, 090, 100, 120, 155, 180,
200 and 240B dual circuit air
handlers. These air handler models
incorporate a single slab coil
assembly, improved application
flexibility, servicing, maintenance
accessibility and an improved
accessory line. They are fully
convertible, (vertical to horizontal
discharge) without field removal or
reorientation of the coil assembly.
They are shipped ready for
horizontal installation.
The TWE090A300C, TWE090B300C,
TWE120A300D, TWE120B300D
models are shipped from the factory
wired for 208-230V/3ph/60 Hz, but
may be field converted for 460V/3ph/
60 Hz applications by changing
voltage plug on the motor. For
voltage change plug instructions,
refer to Figure 9.
All units (both single and dual
circuit), have one drain pan that can
be installed in any one of four
positions. This allows for vertical or
horizontal applications and right or
left exit.
Note: The TWE060B, TWE090B,
TWE100B, and TWE120B
dual circuit air handlers have
a split face coil. When they
are installed in either
position, the lower half of the
coil is designated as “Circuit
A” and should always wet
first.
The TWE155B, TWE180B, TWE200B
dual circuit units have a mixed face
coil.
Note: Note: The TWE050, 060, 075,
090, 100 and 120 air handlers
have structural provisions to
allow 180 degree rotation of
discharge panel/blower
assembly at installation. A
reversible discharge wiring
kit, BAYWRKT001A is
available with instructions.
Installation procedures should be
performed in the sequence that they
appear in this manual. Do not
destroy or remove the manual from
the unit.
The manual should remain weather-
protected with the unit until all
installation procedures are
complete.
Note: It is not the intention of this
manual to cover all possible
variations in systems that

shipping damage. If damaged, it
must be reported to, and claims
made against the transportation
company. Compare the information
