1.19 Inspecting the Cooling Water Concentration
Inspect the cooling water concentration using a coolant tester.
The concentration should be 50%.
1.20 Inspecting the Oil Pressure Switch
Test the continuity between A and B terminals with a tester.
With the oil pressure switch removed, check the engine oil pressure using a Bourdon tube
pressure gauge via a joint.
1.21 Inspecting the Cooling Water Temperature Sensor
Test the resistance between A and B terminals with a tester.
For the temperature/resistance characteristics, see
page 225 [Table7.3 List of resistance/
temperature characteristics of outdoor unit sensors] .
