| This pressure switch has 3 functions: |
| 1. Switches the coolant fan to the next higher level when
the pressure in the refrigerant circuit increases (approximately
16 bar (232 psi)). |
| 2. Switches off A/C system if pressure is excessive
(approximately 32 bar (464 psi)), for example. because of
insufficient engine cooling. |
| 3. Switches off A/C system if pressure is insufficient
(approximately 2 bar (29 psi)), for example. loss of
refrigerant. |
Note
| A/C Pressure Switch -F129- replaces the A/C Refrigerant High
Pressure Switch -F23-, A/C Refrigerant Low Pressure Switch -F73-
and the Magnetic Clutch High Pressure Switch -F118-. |
