DESCRIPTION AND OPERATION

Refrigerant Containment Switch

A refrigerant containment switch is used on all models with air conditioning to interrupt A/C compressor (19703) operation in the event of high system discharge pressures that could result in the loss of refrigerant charge. The switch is located in the discharge line between the compressor and the A/C condenser core (19712). The switch is sensitive to the discharge pressure and functions to interrupt the A/C compressor operation if the discharge pressure exceeds a setting of 2965-3241 kPa (430-470 psi). The single-function switch only controls the circuit to the A/C cycling switch (19E561). When replacing the switch, tighten to 7-13 Nm (62-115 lb-in).
