500945 - 0010T84 AIR CONDITIONING system COOLANT - Dry and repressurize

Follow the recommended safety instructions (see 5040 - Precautions).

1. Use the special draining and repressurizing equipment. - Let the engine run with the air conditioning on for 10 - 15 minutes.1. Undo the repressurizing valve caps.2. Before fitting the connectors on the needle valves, move the knurled ring nut upwards.3. Connect the high pressure connecting pipe to the corresponding red coloured rapid attachment valve.4. Connect the low pressure connecting pipe to the corresponding blue coloured rapid attachment valve.

To improve safety the rapid connectors for the equipment connecting pipes have different diameters and are different colours: the low pressure side is larger and blue, whilst the high pressure side is smaller and red.

- Start the procedure for draining the refrigerant fluid, following the instructions in the equipment manual.1. Whilst draining the system the compressor fluid that comes out collects in a special container.

The fluid is extremely hygroscopic: avoid leaving the containers open.

- Refill the system with exactly the same amount of fluid indicated on the container.

- If some of the components are being replaced, the following amount of oil must be added for each of the replaced components:- Drier filter: 15 cm3- Pipes: 5 cm3/m- Evaporator: 40 cm3- Condenser: 40 cm3- If there are accidental breaks that cause the "rapid" draining of the system (in less than 5 minutes) then the exact amount of fluid that comes out cannot be determined because the high pressure may cause seepage. Integrare con una quantità indicativa di olio di 75 cm³.- Start the procedure for repressurizing the refrigerant fluid, following the instructions in the equipment manual. - Add the recommended quantity of refrigerant fluid.

- In the case of damage to the compressor or other system components or following prolonged exposure of the pipes to the air (more than 6 hours) the WASHING procedure must be carried out as follows.- Clean the pipes connected to the compressor using a jet of air.

Use filtered air to prevent the introduction of foreign bodies into the system.

- Connect the (drained) system to the repressurizing equipment.- Introduce the recommended quantity of refrigerant fluid at the high pressure side.- Collect the refrigerant fluid at the low pressure side.- Repeat the introduction and collection of fluid.- Proceed with draining and repressurizing the system as illustrated previously.

If the system is WASHED the entire amount of compressor oil in the system will be removed.

- Refill the system with exactly the same amount of fluid indicated on the container.
