Safety Precautions
TO PREVENT CROSS-CONTAMINATION, USE THIS MACHINE WITH R-134A REFRIGERANT ONLY.
The machine is equipped with special connectors to recover, recycle, and recharge only R-134a refrigerant.
Do not attempt to adapt the machine 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 machine and the vehicle air
conditioning system.
DO NOT USE THIS MACHINE IN DIRECT SUNLIGHT. Position the machine far from heat sources, such as
direct sunlight, which can cause excessive temperatures. The use of this machine under normal environmental
conditions (10°C to 50°C) keeps pressures under reasonable limits.
DO NOT USE THIS MACHINE OUTDOORS DURING RAIN OR HIGH HUMIDITY. Protect the machine from
conditions that can cause electrical failure or other hazards relating to ambient interaction.
DO NOT USE THIS MACHINE IN AREAS WHERE THERE IS A RISK OF EXPLOSION.
SET UP THE MACHINE ON AN EVEN SURFACE AND UNDER SUFFICIENT LIGHTING. LOCK THE FRONT
WHEELS, AND DO NOT SUBJECT THE MACHINE TO VIBRATION.
TO AVOID CHEMICAL INCOMPATIBILITIES WITH THE INTERNAL COMPONENTS OF THE MACHINE,
USE ONLY OILS APPROVED BY THE VEHICLE MANUFACTURER. Problems resulting from the use of
non-approved oils will void the warranty.
Additional health and safety information can be obtained
from refrigerant and lubricant manufacturers.
Protective Devices
The machine is equipped with the following protective devices:
Over pressure valves.
A maximum pressure switch stops the compressor when excessive pressure is sensed.
WARNING: Tampering with these protective devices could result in serious injury.
Refrigerant Tank Test
Ofcial records and recurring tests necessary for pressurized instruments are governed by laws and/or national
regulations dependent upon the country where the refrigerant tank is used. The system manager is responsible
for compliance with laws, regulations, and technical rules. During normal service, refrigerant tanks do not
need maintenance. Refer to the Maintenance section of this manual for more information.
