designs and developments. The customer 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 using 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 FOR FUTURE 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.

Recovery tank contains liquid refrigerant under high pressure. Never over fill recovery tank. Tanks should be filled to a
maximum of 80% of capacity only. Use scale and connection to recover tank’s float switch to make sure tank is not over
filled. Recovery system with automatic shut down switch must be connected to recovery tank float switch for proper
operation. Use only approved tanks for refrigerant recovery. Use Mastercool DOT cylinder with float switch (part no.
62011-LH.

An over filled tank can explode causing serious injury or death.

ELECTRICAL SHOCK HAZARDS

• Make sure system is electrically connected to a properly grounded power source.

• To reduce the risk of electric shock, unplug the air service center from the outlet before attempting any
maintenance or cleaning. Turning off controls will not reduce this risk.

• Do not operate the machine with a damaged cord or plug — replace the cord or plug immediately. To
reduce the risk of damage to electric plug and cord, disconnect recovery machine by pulling on the plug

rather than the cord.

An extension cord should not be used unless absolutely necessary. Use of an improper extension cord could result in a
risk of fire and electric shock. If extension cord must be used, make sure:
a. That pins on plug of extension cord are the same number, size, and shape as those on machine recovery plug.
b. That extension cord is properly wired and in good electrical condition; and

c. That the wire size is large enough for the length of cord as specified below:

Length of cord in feet: 25 50 100 150
AWG size of cord: 16 12 10 8

MOTION HAZARDS

• Engine parts that are in motion and unexpected movement of a vehicle can injure or kill. When working
near moving engine parts, wear snug fit clothing and keep hands and fingers away from moving parts.
Keep hoses and tools clear of moving parts. Always stay clear of moving engine parts. Hoses and tools can
be thrown through the air if not kept clear of moving engine parts.

• The unexpected movement of a vehicle can injure or kill. When working on vehicles always set the parking

brake or block the wheels.

FUME HAZARDS

• FUMES, GASES, AND VAPORS CAN CAUSE DISCOMFORT, ILLNESS, AND DEATH! To reduce the risk of
discomfort, illness, or death, read, understand, and follow the following safety instructions. In addition,
make certain that anyone that uses the equipment understands and follows these safety instructions as
well.

• Avoid breathing A/C refrigerant and lubricant vapor mist. Exposure may irritate eyes, nose, and throat.

• To remove R1234yf from the A/C system, use certified service equipment. Additional health and safety
information may be obtained from refrigerant and lubricant manufacturers.

• Always perform vehicle service in a properly ventilated area. Never run an engine without proper ventilation for its
exhaust.

• Stop the recycling process if you develop momentary eye, nose, or throat irritation as this indicates inadequate
ventilation. Stop work and take necessary steps to improve ventilation in the work area.

HEAT/FREEZING HAZARDS

• When under pressure, refrigerants become liquid. When accidentally released from the liquid state they
evaporate and become gaseous. As they evaporate, they can freeze tissue very rapidly. When these gases
are breathed in, the lungs can be seriously damaged. If sufficient quantities are taken into the lungs,
death can result. If you believe you have exposed your lungs to released refrigerant, seek immediate
medical assistance.

• Refrigerants can cause frostbite and severe burns to exposed skin. Refrigerants are under pressure and
can be forcibly sprayed in all directions if carelessly handled. Avoid contact with refrigerants and always
wear protective gloves and make certain other exposed skin is properly covered.

• Refrigerants can also severely injure or cause permanent blindness to unprotected eyes. Refrigerants are under
pressure and can be forcibly sprayed in all directions if carelessly handled. AVOID CONTACT WITH REFRIGERANTS AND
ALWAYS WEAR SAFETY GOGGLES.

EXPLOSION/FLAME HAZARDS

• Check hose gaskets for damage that could cause leaks before each use.

• For general safety reasons, at the end of the working day or in between services (when services do not
immediately follow), make sure all valves on hoses and tanks are closed.

• Do not use this Recovery System in the vicinity of spilled or open containers of flammable substances
(gasoline, solvents, etc.).

ADDITIONAL SAFETY INFORMATION

For additional information concerning safety, refer to the following standards.

CAUTION: This equipment should be used in locations with mechanical ventilation that provides at least four
air changes per hour or the equipment should be located at least 18 inches (457 mm) above the floor,” or the
equivalent.

CAUTION: Do not pressure test or leak test refrigerant service equipment and/or vehicle air conditioning systems
with compressed air. Some mixtures of air and refrigerant have been shown to be combustible at elevated
pressures. These mixtures, if ignited, may cause injury or property damage. Additional health and safety
information may be obtained from refrigerant manufacturers.

Attention: Technicians using this equipment must be certified under EPA Section 609 (Environmental Protection Agency).
