Refrigerant Recovery
Important: Use only a refrigerant tank that is designed
for the charging station in use. The unit’s overfill limita-
tion mechanism is calibrated specifically for use with this
tank. The tank’s valves are also specifically for this unit.
1. Attach the high side hose with the quick disconnect
coupler to the high side fitting of the vehicle’s A/C
system.
2. Open the coupler valve after attachment.
3. Attach the low side hose with the quick disconnect
coupler to the low side fitting of the vehicle’s A/C
system.
4. Open the coupler valve after attachment.
5. Check the high side and the low side gauges on the
unit’s control panel in order to ensure that the A/C
system has pressure. If there is no pressure, there
is no refrigerant in the system to recover.
Important: If there is no refrigerant in the system, do
not continue with the recovery operation. This will draw
air into the recovery tank.
6. Open both the high side and the low side valves.
7. Open the gas and the liquid valves on the tank.
8. Drain any oil that may be in the oil separator.
9. Close the oil drain valve.
10. Plug the unit into the proper voltage outlet.
11. Turn on the main power switch.
Notice: Never reuse refrigerant oil. Damage to the A/C
system may result. Dispose of the refrigerant oil proper-
ly.
12. Begin the recovery process. Refer to the manufac-
turer’s instructions for the charging station in use.
Important: Some A/C system PAG lubricating oil may
be removed with the refrigerant during recovery. The
amount of oil removed varies. A charging station sepa-
rates the oil from the refrigerant and allows a means of
determining how much oil was removed. Replace the
same amount of oil when you recharge the system. Re-
fer to the manufacturer’s instructions for the charging
station in use.
13. Wait 5 minutes. Check the control panel low side
gauge. If the A/C has maintained vacuum, the re-
covery is complete.
14. There is more refrigerant in the system if the low
side gauge pressure rises above zero. Recover the
additional refrigerant. Repeat this step until the sys-
tem maintains vacuum for two minutes.
Important: If the control indicator shows that the refrig-
erant tank is full during the recovery process and the unit
shuts off, install an empty unit tank to store the refriger-
ant needed for steps later in the procedure. Do not use
any other type of tank.
Evacuation
The unit tank must contain a sufficient amount of R-134a
refrigerant for charging. Check the amount of refrigerant
in the tank. If there is less than 3.6 kg (8 pounds) of re-
frigerant, add new refrigerant to the tank. Refer to the
manufacturer’s instructions for adding refrigerant.
1. Verify that the high side and the low side hoses are
connected to the A/C system. Open both the high
side and the low side valves on the unit’s control pan-
el.
2. Open both the gas and the liquid valves on the tank.
Important: Refer to the manufacturer’s instructions for
the charging station in use. It is necessary to evacuate
the system before recharging it with new or recycled re-
frigerant.
3. Start the vacuum pump and begin the evacuation
process. Non-condensable gases (mostly air) are au-
tomatically vented from the tank during the recycling
process. You may hear the pressure being released.
4. Check for leaks in the system. Refer to the manufac-
turer’s instructions for the charging station in use.
Important:
Change the vacuum pump oil frequently. Refer to the
manufacturer’s instructions for the charging station in
use.
A/C System Oil Charge Replenishing
Any oil removed from the A/C system during the recov-
ery process must be replenished at this time.
1. Use the correct graduated bottle of polyalkaline glycol
(PAG) oil for the R-134a system.
Important:
Keep the oil bottles tightly capped at all times to pro-
tect the oil from moisture and contamination.
Never open the oil injection valve while there is posi-
tive pressure in the A/C system. This will result in oil
blow-back through the bottle vent. You must have
A/C system vacuum for this operation.
Never let the oil level drop below the pick-up tube
while charging or replenishing the system. This will
allow air into the A/C system.
2. Refer to the manufacturer’s instructions for the charg-
ing station in use. Add the proper amount of PAG oil
to the system.
3. Close the valve when the required oil charge has
been pulled into the system.
Charging
Important: Evacuate the air conditioning system before
charging.
1. Close the low side valve on the control panel.
2. Open the high side valve on the control panel.
