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. Insulate the Thermal Bulb and Suction Line
If it is necessary to change the installed position of the air handler in the field, a two step process is
required:
1. The thermal bulb on the suction line extension must be re-located so the thermal bulb is on a
HORIZONTAL section of the suction line extension, as shown in Figures 10 and 11, with the
thermal bulb located in the 3:00, 4:00, 8:00 or 9:00 o’clock positions as illustrated. Wrap the
thermal bulb with the insulation as shown in Figure 12.
2. The distributor must be reoriented so that in its final installation position it is vertical (up or down)
to ensure equal distribution of refrigerant to each of the coil circuits. Rotate the distributor 90º in
steps, while simultaneously reconfiguring the coil feeder tubes to avoid kinking and ensure
smooth refrigerant flow to the circuits. When completed, the reconfigured distributor and feeder
tube arrangement should look similar to those in Figure 13.
