Original publication.
Debris can be dispersed throughout the refrigerant circuit after A/C component damage. In order to

maintain A/C operating efficiency, it is important to flush the refrigerant circuit after A/C component

repairs.
This bulletin must be read in its entirety before beginning repair.
Technical Background

In cases where an air conditioning system component (such as a compressor or other system

component) has failed and debris from the compressor or component is circulated throughout the

refrigerant circuit, the refrigerant circuit must be cleaned of any and all debris or damage to the

replacement components will result.
If the HV system is disabled, the cooling performance test cannot be performed, and separate

diagnosis is required. The HV AC compressor must have a GFF diagnosis log with completed

test plans of all compressor related faults before replacing the HV AC compressor.

The VAS 6338/1 Adapter Set for Refrigerant Circuits along with an additional adapter VAS

6338/38 for the expansion valve bypass this kit, contains the adapters necessary to complete a

thorough flush operation of a contaminated circuit. Elsa contains the technical information for

each model regarding the necessary adapter applications and connections of the servicing

station for the flush operation. See Heating, Ventilation & Air Conditioning >> Refrigerant

R1234yf-Servicing >> 00 General Technical Data>> Refrigerant Circuit removing contaminates>>

Refrigerant Circuit, Flushing with Refrigerant R1234yf in Elsa
Procedure

To access the expansion valve for removal you must remove the Heating Ventilation Unit.

Refer to Elsa Pro –Elsa2Go Heating, Ventilation & Air Conditioning 87 Air Conditioning Front Heater and

A/C Unit, R134a/R1234yf Heater and A/C Unit Air Intake Housing, Removing and Installing.
Deactivation of the HV battery is required. Perform the HV battery test plan in Guided Functions.

1. If an air conditioning component has been diagnosed as the root cause of the failure, and this particular

component has been verified to have released debris through the circuit, continue with the flush

procedure.

2. Switch the power to the servicing station ON and begin by recovering the refrigerant from the system

through the normal service fittings.
For all compressor replacements it is mandatory to flush the system of all oil in the system. The

replacement compressor comes with a full charge of oil for a complete A/C system.
During the entire process avoid interrupting the power to the station. The station’s internal

memory will keep a log of all operations and can conveniently be recalled and printed. If the

power is interrupted, the station will lose the memory of the refrigerant volume recovered.
