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.
The unit is designed to recover, recycle, and recharge either R-134a or R-12
refrigerant! The user must dedicate the unit to only one type of 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.
Recovering the A/C System Refrigerant
Use the following steps to recover refrigerant from the vehicle’s A/C system.
1. Plug the user supplied power cord into a correct voltage outlet, and turn
the unit ON. Note: It is normal to hear air purge from the tank every time
the unit is powered.
2. Connect the service hoses to the A/C system. IMPORTANT: Connect
the red service hose to the A/C system’s high side; connect the blue
service hose to the low side.
