312002059 - 0010T84 COOLANT FOR AIR CONDITIONING SYSTEM - DEHYDRATE AND REPRESSURIZE

Follow the safety instructions

Op. 5040 AIR CONDITIONING CASING AND COMPONENTS 1. Use the special draining and repressurizing equipment.

- Let the engine run with the air conditioning on for 10 - 15 minutes.- Undo the plugs in the high and low pressure pipes connected to the compressor. 1. Connect the station high and low pressure pipes to the respective pipes at the compressor.

For safety reasons, the rapid connectors for the station pipes are different diameters for the high and low pressure sides. The diameter of the high pressure pipe is smaller than the one for the low pressure pipe.

- Start the procedure for draining the coolant 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.

Component	Type	Description	Classification	Quantity	Validity
DENSO SCS06 compressor	Oil	ND8	-	-	all versions

In the case of operations that involve replacing some of the system components, special oil must be added, in the quantities indicated below, before refitting:

Pipes: 5 cm³/m;
Evaporator: 40 cm³;
Condenser with integrated filter: 50 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. Add the following recommended amount of oil 75 cm³.

- Start the procedure for repressurizing the refrigerant fluid, following the instructions in the equipment manual.- Add the recommended quantity of coolant.

- 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 coolant at the high pressure side.- Collect the coolant at the low pressure side.- Repeat the introduction and collection of fluid.- Proceed with draining and repressurizing the system as illustrated previously.
