TXV Kit Installation – ETI Air Handlers
Air handlers that are intended for HEAT/COOL applications, are shipped with the matching TXV
Kit that must be field installed to enable operation of the system in the cool mode.
The following procedure is for the installation of the TXV Kit which must be done prior to making the
line set connections to the air handler.
Figure 3 illustrates the TXV Kit as shipped with the external parts for field installation identified. In
Figure 3, the pressure equalizer tubing and suction line Tee are shown connected to the control box
for illustration purposes. These parts are shipped with the TXV control box and are field assembled
to the control box and to the suction line. The TXV (thermal expansion valve), CAV (cooling assist
valve) and interconnecting tubing are located inside the control box to ensure performance.
Figure 3. TXV Control
TXV–CLP-KIT (07/15) Page 9
The TXV control box is field positioned external to the vertical (upflow or downflow) air handler and
fastened to (1) the air handler as shown in Figure 4a,or (2) on a solid mounting surface immediately
adjacent to the air handler as shown in Figure 4b. Locate the TXV control box to allow a service
access of at least 12 inches in front of the box to adjust the TXV control.
Figure 4a. TXV Control Installed on Vertical (upflow/downflow) Air Handler
Important!
The TXV control box must be located no more than 3-1/2 feet from the suction
tube stub out on the air handler. The TXV control box must be mounted above
the air handler tubing stub outs as shown.
TXV–CLP-KIT (07/15) Page 10
Figure 4b. TXV Control installed next to Vertical (upflow/downflow) Air Handler
For horizontal air handler applications (left or right air flow), the TXV control box is field positioned
external to the air handler and can be fastened to (1) a cabinet side surface or (2) on a solid
mounting surface immediately adjacent to the air handler as shown typically in Figures 4c and 4d.
Important!
The TXV control box must be located no more than 3-1/2 feet from the suction
tube stub out on the air handler. The TXV control box must be mounted above
the air handler tubing stub outs as shown.
