Important

The optic cables must be handled carefully so as not to distort the signal.

• It is extremely important that the two leads in the connector are not mixed up.

• The cables cannot be spliced.

• The lead must not be bent to form a curve with a radius of less than 25 mm.

• The lead must not be subjected to temperatures greater than 185°F (85°C).

• The lead ends should be kept free from dirt.

• The lead must not be subjected to blows that could cause the transparent plastic to whiten, thereby reducing light intensity. This could cause disruptions in communication.

• The lead should not be stretched across a sharp edge, which would cause increased damping of the signal.


To remove


1. Drain the refrigerant from the A/C system, see Draining and filling the refrigerant .

2. Drain the coolant from the car by loosening the coolant hoses from the heat exchanger by the connections from the heat exchanger and blow with compressed air. Use personal protection equipment.

Place a container under the car to collect the coolant.

3. Dismantle the dashboard .

4. Remove the bulkhead cover .

5. Dismantle the expansion valve's PAD connections

6. Dismantle the steering wheel member .

7. Carefully lift out the heating and ventilation unit. Take care not to spill any coolant from the heat exchanger. Have a cloth ready.


To fit


1. Fit the heating and ventilation unit by lifting the heating and ventilation unit into its position. Exercise care so that the heat exchanger pipe enters the rubber seal correctly, in the bulkhead partition, without damaging the seal.


Note

Take care so that the drainage pipe aligns correctly.


2. Adjustment the oil quantity in the A/C compressor according to Filling and adjusting the compressor oil .

3. Replace the sealing washers and fit the expansion valve's PAD connections.

Tightening torque 15 Nm (11 lbf ft)

4. Fit the steering wheel member .

5. Fit the dashboard .

6. Fit the cover for the bulkhead partition space .

7. Vacuum pump the A/C system and fill with refrigerant. See Draining and filling the refrigerant .

8. Fill with coolant and vent the cooling system .
