BMW X5: Leak Testing With Ultraviolet Additives (UV Additives) (BMW Leak-Testing Case)

BMW X5 (G05) 2019-2024 Service & Repair Manual / Heating And Air Conditioning / Air Conditioning Systems / Leak Testing With Ultraviolet Additives (UV Additives) (BMW Leak-Testing Case)

IMPORTANT: It is absolutely essential to read and comply with the equipment manufacturer's instructions for use provided in the equipment case!

Read and comply with the instructions for use provided with the special tool particularly with regard to accident prevention, health protection and environmental protection.

Use only BMW-approved UV-additives (e.g. TRACER).

Only the basic procedure is described in the following!

WARNING: Avoid contact with refrigerant.

Follow safety precautions when handling refrigerant.

IMPORTANT: UV lamp gets very hot in the radiation area! Do not use the UV lamp without the filter glass.

Eyes and skin will suffer damage if the UV lamp is used without the filter glass.

When using the UV lamp, wear the protective goggles provided in the case.

NOTE:

Necessary preliminary tasks:

Before actually testing for leaks, check the entire refrigerant circuit using the UV leak-detecting lamp to ensure that no AV additive is already in the area of the refrigerant circuit.

If already illuminated areas are found, carefully clean the area in question with the cleaning agent contained in the case.

On initial use : Connect hand pump (1) to additive cartridge (2) and hose piece (3).

On initial use :

Attach vent valve (1) to quick-connect coupling (2).

Turn handle (3) on hand pump to advance the plunger until a small amount of UV additive emerges. This vents the hose system.

IMPORTANT: The entire hand pump with hose system must not be disassembled again once the filling work has been completed.

Attach quick-connect coupling (1) to low-pressure connection (2) of A/C system.

Turn handle on hand pump (3) until the required amount of UV additive is added.

The quantity of UV additive to be added is dependent on the amount of refrigerant in the refrigerant circuit :

NOTE: After filling, remove quick-connect coupling (1) and if necessary use the cleaning agent contained in the special tool case to clean up the UV additive.

Further tasks :

Complete accompanying information label (1) with the relevant data and attach in an easily visible position next to the filling capacity information label (2).
