Filter maintenance

The filter retains acid and particles of certain dimen-

sate and contaminants, the filter must be replaced

The station warns when the filter capacity of
56 kg (123 lb) is reached and stops operating when
the filter capacity is reached, that is 68 kg (150 lb)
WARNING: to prevent injuries while work-
ing with the refrigerant, read and follow

ual, and wear protective clothing, such as
