Txv bulb placement. 1 The expansion valve must be installed in the liquid line. Attach straight flare to inlet side of TXV. Where should the external equalizer be installed? The external expansion valve includes the external equalizer line. Always insulate the sensing bulb after installation to prevent false readings from ambient air temperature fluctuations. Without that contact, the refrigerant in the bulb can’t pick up the temperature of the refrigerant in the suction line and adjust the opening force of the TXV. Attach and secure TXV sensing bulb to horizontal section of vapor/suction line using clamps provided (see Figure 2). Avoid common mistakes that can damage the bulb, the capillary tube, and the TXV diaphragm. The important points to follow are: Clean the suction line near the outlet of the evaporator. Mount it TIGHTLY with a proper metallic strap (usually copper, brass, or stainless steel)—not with zip ties or tape.
