The drier bottle or drier insert does not have to be replaced at regular service intervals in a functioning, leakproof A/C system.
However, the drier bottle or drier insert must be replaced without fail in the event of:
- fouling of the refrigerant by filings/shavings (e.g. when the compressor is clamped).
- a leaking A/C system or loss of refrigerant.
- the refrigerant circuit being opened for a period exceeding 24 hours, e.g. during repair work.
