Page 7: Thermal Bulb Location And Field Conversion
Figure 7. AVS Series Variable Speed Air Handler Dimensions and Electrical Ratings. Thermal Bulb and Field Conversion The air handler is shipped from ETI as it was ordered, either for vertical or horizontal installation. Figure 8 illustrates an air handler shipped from the factory with the TXV thermal bulb attached to the suction tube. - Page 8 The thermal bulb must be located and clamped to a HORIZONTAL extension of this suction tube, with options for the suction tube extension illustrated in Figure 9. This shows the suction tube directional options for an air handler that is to be installed in the VERTICAL direction. Figure 9.
- Page 9 Figure 10 illustrates locating the thermal bulb on the suction line extension. It shall be located at least 6 inches downstream of any fitting or bend in the suction tube extension, and at the 3:00, 4:00, 8:00 or 9:00 o’clock positions. Figure 10.
- Page 10 Clamp the thermal bulb firmly against the clean suction tube extension and parallel to it, as shown in Figure 11, to ensure good thermal contact along the entire length of the thermal bulb. Figure 11. Clamp the Thermal Bulb to the Suction Line Extension AVS-410CH-IM (10/13) Page 10...
- Page 11 After the thermal bulb is secured with the clamp, wrap the provided insulation around the thermal bulb and suction tube extension to isolate the thermal bulb from the surrounding air as shown in Figure 12. Apply the wire tie to hold the thermal bulb tube secure against the suction line as shown in Figure 12. Figure 12.
