Installation

The installation is carried out in the reverse order:

- before installation, add compressor oil to the compressor or condenser, according to the table in the article - How to unload and load the refrigerant of the Lada Largus air conditioning system;
- before installing the tubes, you need to replace the o-rings and apply compressor oil to them;
- tightening torque of the bolt for fastening the tube connecting the compressor with the evaporator (short part) to the evaporator - 8 Nm;
- tightening torque of the bolt for fastening the tube connecting the compressor to the evaporator (long part) - 8 Nm

We perform evacuation of the air conditioning system and load the system with R134a refrigerant, in the amount of 475±35g.

Checking the system for tightness and operability of the air conditioner.
