• Available power supply must agree with electrical
data on component nameplate.
• Some constant volume air handlers are shipped
wired for 208-230 volt applications and can be
converted for 460 volt by rewiring the blower
motor. (This includes models TWE07243B,
TWE09043A, TWE09043B, TWE12043A,
TWE12043B, TWE15043B and TWE18043B).
Converting Motor to 460 Volt
IIm mp po orrtta an ntt:: Units ordered with a VFD cannot be field
converted to 460 V from 208-230 or from
208-230 V to 460 V.
1. Ensure power is disconnected to unit by following
the warning above.
2. Remove unit access panels closest to motor.
3. Open terminal cover on lead end of motor.
4. Pull voltage selector plug from low voltage
selection (see Figure 3, p. 9 ).
5. Shift the plug (or rotate 180°) to align plug for high
voltage selection and re-insert plug.
IIm mp po orrtta an ntt:: When re-inserting voltage selection
plug, ensure it is fully seated.
6. Replace terminal cover on lead end of motor.
7. Replace unit access panels.

To change voltage, pull plug, rotate 180° and reinsert

To change voltage, pull selector plug out, shift plug
to align arrow to 460V for high voltage or 230V for
low voltage as desired. Push plug back in.

Reorienting Evaporator Coil (TWE126/
150 and 156/180)
IIm mp po orrtta an ntt:: Applies to TWE126/150 and 156/180 when
positioned for vertical upflow. Unit is
shipped in the horizontal position. If
installing in the v
ve errttiicca all p po ossiittiio on n, the coil
m mu usstt b be e reoriented by rotating the coil 4
degrees (control box side) from the
shipped position.
1. Remove screws from top evaporator coil bracket
(bracket that attaches coil to cabinet and runs the
length of the unit). See
Figure 4, p. 10 .
2. Rotate evaporator coil approximately 4 degrees
clockwise - looking from the control box end. When
the evaporator coil is rotated, the lower set of
evaporator coil bracket holes will align with the
support bracket (from which it was originally
fastened).
3. Reinsert screws in evaporator coil bracket.
