Page 3: Section 2. Overview And Common Steps
Section 2. Overview and Common Steps These instructions are designed for installing a replacement coil into a previously installed air handler. The air handler may be installed in one of the fol- lowing orientations: upflow, downflow, horizontal left or horizontal right. In addition, the coil could be a flat coil (not pictured) or an “A”... -

Section 3. Coil with a Mechanically Fitted TEV 3.1 Remove the existing coil 3.2 Remove the TEV from the Existing coil Note: Caution must be used not to damage the TEV, equalizer line, or sensing bulb. This TEV will be reattached to the replacement coil. 3.3 Installing the TEV onto the replacement coil 1) To install the metering device, remove the... - Page 5 3) Bolt the TEV (which was removed from the original coil) to the distributor assembly. (See Figure 5) Note: Torque specification for TEV equals 1/6 turn past finger tight. Figure 5 - Installing TEV 4) Connect the liquid line from the removed coil to the TEV by bolting it to the refrigerant enter- ing connection of the TEV.

5) Remove the Schrader core from the brass fit- ting on the suction manifold before connecting the equalizer line. (See Figure 8) 6) Connect the equalizer line to the brass fitting on the suction manifold. (See Figure 9) For coil replacement and reconnection instruc- tions, see Section 6. - Page 7 Note: Wet rags must be applied to all braze joints before and during heating to prevent overheating of internal coil components. (See Figure 10) 5) Field fabricate a new liquid line using field- supplied 3/8” OD copper tubing and fittings. Route this line toward the suction manifold side of the coil and through the coupling panel to the existing field lineset.

Section 5. Coil with a FCCV 5.1 Removing the FCCV Note: The FCCV will be reused in the replace- ment coil. DO NOT discard. 1) Disconnect the liquid line to remove the FCCV from the fitting. Retain for later installation in the new coil. - Page 9 Note: Wet rags must be applied to all braze joints before and during heating to prevent overheating of internal coil components. (See Figure 10) 5) It is necessary to remove the solder cap from the short liquid line to connect a field fabri- cated liquid line.

Page 10: Section 6. Reconnecting New Coil Assembly
Section 6. Reconnecting new coil assembly 1) Put the new coil assembly into the air handler using care not to damage any of the coil com- ponents. Note: Make sure the coil fits into the rails or channels the failed coil was removed from. If previous coil was secured with screws, rein- stall them now. - Page 11 Note: Steps 6 and 7 do not apply to units equipped with FCCV. 6) Attach the TEV sensing bulb to the suction manifold. The bulb should be between the 8 - 4 o’clock position on the line. (See Figure 18) 7) Insulate the TEV sensing bulb.
