Page 6: Installation
Installation Component Matching CCA Series Cased Coils are ready for vertical installation as shipped. Field conversion to horizontal requires no additional components. The CCA Series Cased Coils are manufactured for vertical and horizontal applications. Heat/Cool and Cool Only (Model CCA-00XX): These cased coils are equipped with a distributor designed for providing optimum performance in the cooling mode and the heating mode. -

Page 11: Txv Kit
TXV Kit Introduction CCA Series cased coils that are intended for HEAT ONLY application are ready to install and make the refrigeration line set connection to the cased coil as shipped. CCA Series cased coils that are intended for HEAT/COOL or COOL ONLY applications, are shipped with the matching TXV Kit that must be field installed to enable operation of the system in the cool mode. -
Page 12: Figure 8A. Txv Control Installed Near Cased Coil (Vertical Application)
The TXV control box is field positioned external to the vertical (upflow or downflow) cased coil and fastened to a solid mounting surface immediately adjacent to the cased coil as shown typically in Figure 8a. 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. -
Page 13: Figure 8B. Txv Control Installed Near Cased Coil (Horizontal Application)
For horizontal cased coil applications (left or right air flow), the TXV control box is field positioned external to the cased coil and can be fastened to a solid mounting surface immediately adjacent to the cased coil as shown typically in Figure 8b. Important! The TXV control box must be located no more than 3-1/2 feet from the suction tube stub out on the cased coil. -
Page 14: Figure 8C. Txv Control Box Dimensions
For mounting purposes, the physical dimensions for the TXV Control Box are shown in figure 8c. The preferred mounting position for the TXV Control Box is vertical with the liquid line tube connections on the bottom. However, as shown in Figure 8d, the Control Box can be mounted from vertical to any angle up to 90 degrees (horizontal). -
Page 15: Figure 8D. Txv Control Box Mounting Positions
Figure 8d. TXV Control Box Mounting Positions The following steps and positioning requirements apply to installing the TXV Control to the cased coil for vertical and horizontal applications. The vertical installation provides an illustrated example. Step 1: Relieve the nitrogen holding charge on the air handler using the valve on the liquid line stub out. Locate the TXV Control box within the 3-1/2 feet of the suction line stub out on the cased coil. -
Page 16: Figure 9. Positioning The Pressure Equalizer Tee
Step 2: Position the Pressure Equalizer Tee on the suction tube at least 10 inches downstream from the 90° ell as shown in Figure 9. Remove the core from Schrader valve on the Tee. Figure 9. Positioning the Pressure Equalizer Tee CCA-410-IM (03/15) Page 16... -
Page 17: Figure 10. Thermal Bulb Positioning
Step 3: The Thermal Bulb must be positioned and clamped to the suction tube as shown in the example illustrated in Figure 10. The Thermal Bulb and suction tube must be horizontal regardless of the cased coil application (vertical or horizontal). The Thermal Bulb must be positioned at the 3:00, 4:00, 8:00 or 9:00 positions on the suction tube, as illustrated in Figure 10. -

Page 19: Figure 13. Txv Liquid Line Connections
Step 5: Measure and cut copper tubing to connect the liquid line from the TXV control box to the liquid line stub out on the cased coil as shown in Figures 7 and 13. Run the other liquid line from the connection on the TXV control box to the compressor unit, also shown in Figure 13. -
