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.

PRODUCT REGISTRATION
To register this MX134 Refrigerant Management Machine for the MAXXAIR™ 1-2-3 product warranty, please visit
www.cpsproducts.com/hvac-warranty-registration/. Please contact us, if you have any technical issues during
registration of this machine.
You may also register this MX134 Machine by using the touch screen (See Page 21).
1. The MX134 Series’ 30lb internal storage tank is designed to contain a maximum of 20.96 Lbs (9.52 Kg) of
refrigerant.
2. If this amount is exceeded, the user will be alerted and system operations will be halted.
3. Before normal operation can continue, the overfill condition must be remedied by moving refrigerant from the tank
to another storage tank or into a vehicle AC system. The charge function may be used to transfer internally stored
refrigerant to an external storage facility.

• This machine is covered under US Patent 8,082,750.
OVERVIEW
This “MX” Series Refrigerant Management Center is for use with R-134a refrigerant and has been designed for automotive
technicians to easily Recover, Recycle, Evacuate and Recharge air conditioning systems in passenger vehicles and light
trucks. It features a seven inch, color touch screen display, a 30 Lb refrigerant tank, an oil-less compressor and motorized
ball valves.

Optional Accessories
• Heater Blanket (#CCXHB) – During colder weather, this CPS 120V AC accessory can be applied to the refrigerant
tank to speed up charging, which eliminates the need to run a vehicle’s AC system.
• TACI100 CarSmart AC Inspector – Includes 2 probes for measuring or data logging temperature, humidity,
dew point, etc., inside of, or around a vehicle.
• 50 Lb Refrigerant Tank – Available from CPS as individual tanks, or in pallet quantities (see page 8)
• Dust Cover (#MXXC) – Fits any CPS MX series machine.
Not Included (Shop Must Purchase)
• R-134a Refrigerant
• Refrigerant oil/dye injection system.
Features Benefits
7” Color Display, With Touch-Screen Icon
User-friendly icons allow fast, easy selection of Recovery,
Evacuation, Charge, Full Cycle and Tank Refill functions, or Setup
and Maintenance Menus.
Vehicle A/C System Database MX machines include a database of refrigerants and refrigerant
oil for most vehicles sold in North America since 1994.
Low and High Side “Barrier” Service Hoses &
Couplings
The included barrier hoses and couplings minimize the loss of
expensive refrigerant, which can also harm the atmosphere.
Filter/Dryer
The installed filter-drier filters the R-134a refrigerant inside the
vehicle’s A/C system, and absorbs any system contaminants
which can reduce compressor life.
Motorized Ball Valves Automatically open or close for a selected charge, recovery or
evacuation routine.
Temperature Probe Accessory MX Machines include a corded probe (#TMX2P) for measuring
temperature in AC vents.
1 Lb (454 Gm) Check Weight For accurately calibrating the installed refrigerant charging scale.
30 Lb Refrigerant Tank
The DOT certified tank is designed to safely recover, charge and
transport refrigerant used with MX machine. Available in single
cylinders or in pallet quantities (see below).
Bluetooth Low Energy (BLE) Capable
MX Series machines can be used with the CPS “CarSmart AC
Inspector” wireless accessory (#TACI100) to log temperature,
humidity, dew point and other diagnostic data inside of, or around
a vehicle.
Wi-Fi Capable
MX Series Machines can be connected to other Wi-Fi devices
or printers and job reports can be e-mailed directly from the
machine.
