Operating Instructions
TO RECOVER REFRIGERANT
Recovery speed and accuracy are highly dependent on underhood temperature
and air flow across components. Cold refrigerant can pool in the accumulator,
evaporator, or condenser, and will continue to increase system pressures even
after the recovery process has ended. For maximum recovery speed and
accuracy, bring the engine to operating temperature before recovering
refrigerant. Run the heater on maximum temperature, maximum blower, and
recirculate. DO NOT run the A/C system, as excessive oil loss will result.
NOTE: There must be 25 psi in the system to recover refrigerant. If there is
not sufficient pressure, you will be prompted to evacuate the system. This step
prevents inadvertent recovery of air or other contaminants from a leaking system.
1. Verify the vehicle engine is OFF.
2. From the MAIN MENU, press the RECOVER key, or the SCROLL
MENU key to move to the screen showing the RECOVER key.
3. Follow the on-screen prompts to connect the service hoses to the vehicle
and open the service couplers, if they are not already connected.
4. Empty the ACR2005 oil drain bottle before starting.
5. Press the START key to begin the recovery process.
6. If sufficient pressure is detected, the ACR2005 tests the vehicle system to
determine the purity of its refrigerant. If the vehicle system’s purity is
sufficient, recovery begins. If the refrigerant is contaminated, see page
12, Vehicles with Contaminated Systems.
7. Before and immediately after recovery, the ACR2005 will, if necessary,
go into a clearing mode. This mode clears all refrigerant from hoses and
internal components into the tank to provide maximum recovery accuracy.
8. When the system has been recovered to a vacuum of 9" Hg, the recovery
process stops automatically. Several things occur at this time:
• The red indicator light flashes and the beeper sounds at completion.
• The display reads RECOVER COMPLETE, and shows the weight of the
recovered refrigerant.
• System oil is automatically drained into the oil drain bottle.
9. You now have the following options:
• Proceed with evacuation or repairs, if needed.
• Press the RESTART RECOVERY key to remove any additional
refrigerant which may have vaporized in the system.
• Wait for the ACR2005 to automatically restart and pull any additional
refrigerant that has vaporized in the system. (Restarting occurs after five
minutes, if a positive pressure is detected.)
Additional recovered refrigerant is added to the amount shown on the screen.
IMPORTANT:
Press PAUSE
to stop
recovery at
any time.
IMPORTANT: If
you operate the
engine during
recovery, see
warnings at the
front of this
manual and
take extreme
care to avoid
moving parts.
