Robinair 178012K Recovery, Recycling, Recharging Unit - Manual (Page 13)

Model 178002K/178012K Recovery/Recycling/Recharging Unit

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 takes from 20
seconds to four minutes to complete. Once the clearing is complete, the unit automati-
cally begins to recover refrigerant from the system. If there is no internal pressure in the
unit, refrigerant recovery begins immediately.
CAUTION! If the A/C system pressure is 25 psi or less, the message
“CH-P” appears on the display to alert you not to attempt recovery from an
empty system. Do not press HOLD/CONT to continue the recovery process
unless you know the A/C system contains refrigerant.
The display shows that the unit is in the RECOVER mode and the AUTOMATIC cycle.
You can monitor the amount of refrigerant removed from the system by watching the
display. The compressor shuts off automatically when recovery is complete (at approxi-
mately 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 cor-
ner of the display will indicate “OIL (OUNCES)” as a reminder.
6. Be sure the oil catch bottle is empty, then slowly open the oil drain valve, and drain
the oil into the oil catch bottle. This oil was removed from the A/C system during
recovery. It must be replaced with new oil. When all the recovered oil has com-
pletely drained, immediately close the valve and record the amount of oil in the
bottle. Dispose of waste oil properly.
If the recovery tank fills completely:
• The compressor shuts off; the digital display shows the message “FULL.”
• Change the tank.
The A/C system is now empty. Make any repairs at this time.
