SAFETY
The following safety information is provided as guidelines to help you operate your new
system under the safest possible conditions. Any equipment that uses chemicals can be
potentially dangerous to use when safety or safe handling instructions are not known or not
followed. The following safety instructions are to provide the user with the information
necessary for safe use and operation. Please read and retain these instructions for the
continued safe use of your service system.
SAFETY INFORMATION
Every craftsman respects the tools with which they work. They know that the tools represent
years of constantly improved designs and developments. The true craftsman also knows that
tools are dangerous if misused or abused. To reduce risk of discomfort, illness, or even death,
read, understand, and follow the following safety instructions. In addition, make certain that
anyone else that uses this equipment understands and follows these safety instructions as well.
READ ALL SAFETY INFORMATION CAREFULLY before attempting to install, operate, or
service this equipment. Failure to comply with these instructions could result in personal injury
and/or property damage.
RETAIN THE FOLLOWING SAFETY INFORMATION FORFUTURE REFERENCE.
Published standards on safety are available and are listed at the end of this section under
ADDITIONAL SAFETY INFORMATION.
The National Electrical Code, Occupational Safety and Health Act regulations, local industrial
codes and local inspection requirements also provide a basis for equipment installation, use, and
service.
The following safety alert symbols identify important safety messages in this manual.
When you see one of the symbols shown here, be alert to the possibility of personal injury and
carefully read the message that follows.
EXPLOSION HAZARDS
Risk of explosion
Do not fill the tank to more than 80% of the maximum capacity.
Explosion can cause death or personal injury.
HEAT/FREEZING HAZARDS
Risk of personal injury
Handle refrigerants and pressure vessles with caution.
Wear safety glasses, gloves, and suitable clothing.
Avoid contact with the skin.
Avoid breathing A/C refrigerant and lubricant vapor mist.
Contact with refrigerant can cause health risks, blindness, and other physical
damage (frostbite) and possibly death.

Risk of personal injury and equipment damage
Always use an identifier before recovering refrigerent from a vehicle.
Recover only the refrigerent the productwas certified to be used with.
Recovery of refrigerents other than the one theunit was certified for may cause
injury, equipment damage and possible death.Alternate refrigerants may contain
flammables such as butane orpropane and can explode or cause a fire.
GENERAL SAFETY MESSAGES
Risk of electric shock
Unplug unit before attempting any maintenance or cleaning.
Do not operate unit with damaged cord or plug.
Electric shock can cause injury or death.
Risk of equipment or circuit damage
Always unplug equipment from electrical outlet when not in use.
Never use the cord to pull plug from an outlet. Grasp the plug
and pull it to disconnect.
If an extension cord is necessary, a cord with a current rating
equal to or more than the equipment should be used. Cords
rated for less current may overheat.
DO NOT adapt your unit for a different refrigerant —system
failure will result. R134a or R1234yf systems have special fittings
(per SAE specifications) to avoid cross contamination.
Improper use of equipment can cause equipment or circuit damage.
Risk of unexpected vehicle movement
Block drive wheels with chocks before performing a test with
engine running.
Unless instructed otherwise, set parking brake, and put gear
selector in neutral or park.
If the vehicle has an automatic parking brake release,
disconnect the release mechanism for testing and reconnect
when finished.
Do not allow bystanders to stand in front of or behind the
vehicle while testing.
Do not leave a running engine unattended.
A moving vehicle can cause death or serious injury.
Risk of personal injury
Keep yourself, clothing and other objects clear of hot or
moving parts.

Keep hoses and cords clear of moving parts.
Do not wear watches, rings, or loose clothing when working in
an engine compartment.
Contact with hot or moving parts can cause injury.
FUME HAZARDS
Risk of fume, gas, and vapor hazards
Avoid breathing A/C refrigerant and lubricant vapor
mist.
Always perform vehicle service in a properly ventilated
area.
Never run an engine without proper ventilation for its
exhaust.
Fume, gas, and vapors can cause irritation to eyes, nose, and throat,
cause illness or death.
ADDITIONAL SAFETY INFORMATION
For additional information concerning safety, refer to the following standards.
ANSI Standard Z87.1 —SAFE PRACTICE FOR OCCUPATION AND EDUCATIONAL EYE
AND FACE PROTECTION - obtainable from the American National Standards Institute, 11
West 42nd St., New York, NY 10036, Telephone [phone], Fax [phone] -

Risk of ventilation hazards
Must have at least four air changes per hour or equipment
should be located at least 18” (457 mm) above the floor.
Poor ventilation can cause irritation to eyes, nose, and throat, illness, or death.
Risk of explosion
Do not pressure test or leak test R134a or R1234yf equipment
and/or vehicle air conditioning systems with compressed air.
Explosion can cause injury or death.
NOTE: Use only new lubricant to replace the amount removed during the recycling
process. Used lubricant should be discarded per applicable federal, state, and local
requirements.
The manufacturer shall not be responsible for any additional costs associated with a
product failure including, but not limited to, loss of work time, loss of refrigerant,
cross contamination of refrigerant, and unauthorized shipping and/or labor charges.
Risk of explosion
Ensure that you are only recovering from the fitting on the AC
system.
Some car manufacturers on the fuel intake manifold install a
connector identical to the A/C low pressure fitting.
Explosion can cause injury or death.
Risk of personal injury
Do not operate equipment with damaged cord or hoses.
Do not operate the unit if it has been damaged until it has been

examined by a qualified service personnel.
Damaged parts can cause injury or death.
HOSES CONNECTION
Hoses may contain refrigerant under pressure. Before disconnecting the quick coupler verify
the corresponding pressure in the service hoses (gauge).
SAFETY DEVICES
The machine is equipped with the following safety devices:
SAFETY PRESSURE SWITCH: Stops the compressor in case of excessive pressure.
SAFETY VALVE: Opens when the pressure inside the system reaches a level of pressure
above the estimated limits.
MAIN SWITCH: Connects and disconnects machine AC electrical power. Disconnect main
power cord from electrical power source before servicing.
ANY KIND OF TAMPERING OF THE SAFETY DEVICES MENTIONED ABOVE IS NOT
ALLOWED.
REFRIGERANT AND LUBRICANT - PERSONAL PROTECTIVE
EQUIPMENT AND PRECAUTIONS
Risk of personal injury
Handle refrigerants and pressure vessles with caution.
Wear safety glasses, gloves, and suitable clothing.
Avoid contact with the skin.
Contact with refrigerant can cause health risks, blindness, and other physical
damage (frostbite).

Should be operated by certified personnel.
Do not remove the seals of the safety valves and control
systems.
Do not use external tanks or other storage containers that are
not approved.
Do not block air vents and ventilation equipment.
Improper use of equipment can cause equipment damage and personal injury.
PRECAUTIONS FOR HANDLING AND USE OF R134a OR R1234yf FLUIDS
Risk of personal injury. Risk for handling pressurized R134a or R1234yf containers
Avoid inhaling highly concentrated vapors.
Avoid use of R134a or R1234yf near open flames and incandescent
elements.

PRINCIPLES OF OPERATION
In a single series of operations, the machine permits recovering and recycling refrigerant fluids
(R134a for ECO NEXT ONE and ECO NEXT ONE HYBRID or R1234yf for ECO NEXT ONE
HFO, depending on machine model) with no risk of releasing the fluids into the environment, and
also permits purging the A/C system of humidity and deposits contained in the oil.
The machine is in fact equipped with a built-in evaporator/separator that removes oil and other
impurities from the refrigerant fluid recovered from the A/C system and collects them in a
container for that purpose.
The fluid is then filteredand returned perfectly recycled to the bottle installed on the machine.
The machine also permits running certain operational and seal tests on the A/C system.
