Removal and installation
1. Disconnect a wire from the negative plug of the storage battery.
2. Remove the refrigerant from the system.
Attention: to avoid contamination of the system, immediately install plugs on the open ends of the pipes.
3. Remove the pressure switch in the sequence of numbers shown in the figure.
1 - connector,
2 - pressure switch.
4. Install in the reverse order of removal.
5. Follow the steps described in subsection "Checking the efficiency of the refrigerant circulation system''.
Examination
1. Connect the gauge block.
2. Disconnect the pressure switch connector.
3. Make sure there is pressure in the high pressure line.
4. Check for continuity between pressure switch connector pins.
If the conductivity is not as described, replace the pressure switch.
