0010T84 COOLANT FOR AIR CONDITIONING SYSTEM DEHYDRATE AND RECHARGE - Fiat - PANDA - eLearn

2752386 - 0010T84 coolant for air conditioning system dehydrate and recharge

Follow the safety instructions (See 0010 - Attention/Warnings).

Let the engine run with the air conditioning switched on for 10 - 15 minutes.Switch off the engine.1. Connect the pressurizing and drainage pipes (1a) for the drainage equipment (1b) to the valves on the air conditioning system high and low pressure pipes.

For improved safety, the rapid attachment connectors for the equipment connection pipes have different diameters and are different colours: the one for the low pressure side is larger and blue and the one for the high pressure side is smaller and red.

Start the procedure for draining the coolant fluid, following the instructions in the equipment manual.Whilst draining the system, the fluid removed from the compressor should be collected in a special container.

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

Refill the system with the same amount of recommended fluid shown on the container.

If certain components are replaced, the following quantities of fluid must be added for each of the components replaced:

Drier filter: 15cm³
Pipes: 5 cm³ /m
Evaporator: 40 cm³
Condenser: 40 cm³

In the case of accidental breakages which result in the rapid draining of the system (in less than 5 minutes), it is not possible to determine the exact amount of fluid which has escaped because of the high pressure of the fluid. Add 75 cm of fluid. Start the coolant fluid repressuring procedure, following the instructions in the equipment manual.Introduce the recommended quantity of coolant fluid.

	Type	Component	Name	Qty.
-	Fluid (g)	Air conditioning circuit	R134a	500 ± 40

In the case of damage to the compressor or other system components followed prolonged exposure to the air of the pipes (more than 6 hours), the system 'WASHING' procedure has to be carried out, proceeding as follows. Clean the pipes connected to the compressor using an air line.

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

Connect the (now drained) system to the repressurizing equipment.Introduce the recommended quantity of coolant fluid at the high pressure side.Recover the coolant fluid from the low pressure side.Repeat the introduction and recover the fluid.Proceed with the system draining and repressurizing operations as described previously.
