The.“CL-L”.message.shows.on.the.display.if.there.is.pressure.in.the.unit,.and.a.
self-clearing.process.of.the.components.begins..You.can.press. HOLD/CONT.to.
bypass.clearing.if.an.accurate.recovery.amount.is.not.required..Otherwise,.the.
compressor.will.start.and.the.“CL-L”.message.remains.on.the.display..This.process.

complete.(at.approximately.13.inches.of.vacuum)..The.display.shows.the.“CPL”.
message,.and.then.alternately.flashes.the.weight.of.refrigerant.recovered.
. 5.. To.assure.complete.recovery.of.refrigerant,.wait.for.five.(5).minutes.and.
watch.the.manifold.gauges.for.a.rise.in.pressure.above.“0.”.If.a.rise.occurs,.
press. HOLD/CONT..Repeat.as.needed.until.the.system.pressure.holds.for.
two.(2).minutes.
CAUTION: Drain the oil from the separator only after each
recovery.
Do not completely depressurize the oil separator; immediately close
the valve when oil is completely drained in the next step. The lower
right corner of the display will indicate “OIL (OUNCES)” as a reminder.
. 6.. Verify.the.oil.catch.bottle.is.empty,.then.slowly open.the.oil.drain.valve,.

A/C.system.during.recovery..It.must.be.replaced.with.new.oil..When.all.the.
recovered.oil.has.completely.drained,.immediately.close.the.valve.and.record.
the.amount.of.oil.in.the.bottle..Dispose.of.waste.oil.in.an.appropriate.manner.
