GENERAL SAFETY INSTRUCTIONS
Only qualified service personnel should operate this machine. Most states, countries, etc... may require the user to be
licensed. Please check with your local government agency.
DANGER – This unit’s recovery tank contains liquid refrigerant. Overfilling of a recovery tank may cause a violent explosion
resulting in severe injury or even death. Do not disable the overfill safety features. Always make sure the correct
tank is on the scale.
DANGER – Only use the specified recovery tanks provided with this unit. See your distributor for replacement tanks.
DANGER – Avoid breathing refrigerant vapors and lubricant vapor or mist. Breathing high concentration levels may cause
heart arrhythmia, loss of consciousness, or even cause suffocation.
DANGER – Electrical shock hazard!!!! Always disconnect power source when servicing this equipment.
DANGER – DO NOT USE COMPRESSED AIR TO PRESSURE TEST OR LEAK TEST THE MX UNIT OR VEHICLE AIR
CONDITIONING SYSTEM. Mixtures of air and refrigerant are combustible at elevated pressures. These mixtures
are potentially dangerous and may result in fire or explosion causing personal injury or property damage.
CAUTION – All hoses may contain liquid refrigerant under pressure. Contact with refrigerant may cause frostbite or
other related injuries. Wear proper personal protective equipment such as safety goggles and gloves. When
disconnecting any hose, please use extreme caution.
CAUTION – Exposure to refrigerant vapors may irritate eyes, nose, throat, and skin. Please read the manufacturers Material
Safety Data Sheet for further safety information on refrigerants and lubricants.
CAUTION – To reduce the risk of fire, avoid the use of extension cords thinner than NO. 16 awg. (1,5mm2). The following table
references extension cord wire size vs. maximum length:
EXTENSION CORD (Imperial) EXTENSION CORD (Metric)
Gauge (awg) Length (Ft)
16 10
14 20
12 25
Gauge (mm2) Length (m)
1.5 3
2.5 6.1
4 7.6
CAUTION – Do not use this equipment in the vicinity of spilled or open containers of gasoline or other flammable substances.
Make certain that all safety devices are functioning properly before operating the equipment.
CAUTION – This equipment should be used in locations with mechanical ventilation that provides as least 4 air changes per hour.
CAUTION – RISK OF INJURY, the equipment should only be operated by certified personnel.
CAUTION – Use only CPS certified hose assemblies on this unit. The hose assemblies are made to proper length, contain
shut-offs where required and have direct affect on the proper operation of this equipment.
CAUTION – R-134a is a Class III highly flammable refrigerant. Use in well ventilated areas. Minimize leakage from the unit.
Periodically check MX134 machine for leaks.
1. The MX134 will alert the user should a high pressure condition exist on the outlet side of the compressor.
2. When such a condition is detected, the compressor will turn OFF and won’t restart until the high pressure condition is remedied.
3. If this occurs, check to ensure that Tank Valves and Hose Ball Valves running to the tank and filters are OPEN.
4. If all valves are open, contact CPS Technical Support to determine the cause of the alarm.
