Recovery & RecyclingCâu 206 / 240
Self-contained (active) recovery equipment differs from system-dependent (passive) equipment in that it:
a.Can only be used on small appliances
b.Has its own compressor and can recover without the appliance's help
c.Requires the appliance's compressor to run
d.Cannot recover liquid refrigerant
Giải thích
Self-contained equipment has its own compressor or pump and can pull refrigerant from any appliance without relying on the unit. System-dependent equipment has no pump and depends on the appliance's own pressure or compressor, so it may be used only on small appliances. Choose active equipment for high- and low-pressure work.
