(Or blow out with compressed air and nitrogen). Refer to REFRIGERANT CIRCUIT, FLUSHING WITH COMPRESSED AIR AND NITROGEN . In the event of:

-- Moisture or dirt has gotten into the refrigerant circuit, for example, after a crash.

-- Refrigerant oil is dark and viscous.

-- There is too much refrigerant oil in the refrigerant circuit after replacing the compressor.

-- The A/C compressor had to be replaced due to "internal" damage (for example, noises or no output).

NOTE:

When flushing components with compressed air and nitrogen, extract the gas mixture escaping from the components thoroughly via an existing exhaust-extraction ventilation system (workshop extraction system).
