Service Solution Manual

VEHICLES WITH CONTAMINATED SYSTEMS

Before every recovery, the 342000 automatically samples the refrigerant in the

vehicle system. The operator may not bypass this procedure. If a system fails the

purity level required, the 342000 tests a second time. In the event the system fails a

second time, the 342000 prompts you to disconnect the hoses from the vehicle.

Follow the on-screen prompts in order to clear out the 342000.

NOTE:

The 342000 must be disconnected from the vehicle before starting the

cleaning process. It is illegal to knowingly vent or allow refrigerant to vent to the

atmosphere. This illegal venting will occur if the machine is left attached to the

vehicle.

Please refer to your shop’s policy for dealing with contaminated refrigerant.

TESTING SOURCE TANKS

Robinair recommends that all source tanks be sampled prior to installation on the

342000. The 342000 does not automatically test the contents of the source tank

prior to adding refrigerant to the internal storage vessel. If a source tank contains

contaminants, these contaminants are transferred to the internal storage vessel.

After a tank fill, the unit samples the contents of the internal storage vessel. When

the internal storage vessel is contaminated, the unit displays:

INTERNAL TANK CONTAMINATION or ID-MALFUNCTION

CONTACT SERVICE

The 342000 locks out all functions until a certified service center decontaminates

the machine. This decontamination is not covered by the warranty.
