Operation
WARNING
Wear safety goggles when working with refrigerant. All hoses may contain liquid
refrigerant under pressure. Disconnect hoses using extreme caution. Read and
follow all warnings at the beginning of this manual before operating the unit.
Do not overfill the internal storage vessel. Overfilling may cause explosion and
serious personal injury or death. If the message OVERLOAD appears in the display
screen, the internal storage vessel is too full — remove refrigerant. If the message
HIGH PRESSURE appears in the display screen, let the unit cool down. If the
message does not clear, call an authorized service technician.
Do not recover or charge refrigerants into nonrefillable containers; use only
authorized refillable refrigerant containers. Do not overfill refrigerant containers.
Overfilling may cause explosion and serious personal injury or death.
Use the unit only with R-134a refrigerant. The unit is for recovering, recycling, and
recharging only R-134a refrigerant! Do not attempt to adapt the unit for another
refrigerant. Do not mix refrigerant types through a system or in the same container;
mixing of refrigerants will cause severe damage to the unit and the vehicle air
conditioning system.

Use the following steps to recover refrigerant from the vehicle’s A/C system.
1. Plug the power cord into a correct voltage outlet.
2. Turn the unit on.
3. Connect the service hoses to the A/C system. IMPORTANT: Connect the
red service hose to the A/C system’s high side and the blue service
hose to the low side.
