Operating Instructions and Parts Manual 24533
AIR VACUUM PUMP
• Always perform vehicle service in a properly ventilated
area. Never run an engine without proper ventilation
for its exhaust. Stop work and take necessary steps
to improve ventilation in the work area if you develop
momentary eye, nose, or throat irritation as this
indicates inadequate ventilation.
• 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.
• Be alert for hot engine parts to avoid accidental burns.
• 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. Avoid contact with refrigerants
and always wear safety goggles.
• Avoid accidental fire and/or explosion. Do not smoke
near engine fuel and battery components.
• The warnings, precautions, and instructions discussed
in this manual cannot cover all possible conditions
and situations that may occur. The operator must
understand that common sense and caution are
factors which cannot be built into this product, but
must be supplied by the operator.
• The manufacturer declines any and all responsibility
for damage to vehicles or components if said damage
is the result of unskillful handling by the operator or of
failure to observe the basic safety rules set forth in the
instruction manual.
DISPOSAL
At the end of the useful life of the Air Operated Vacuum
Pump, dispose of the components according to all
state, federal, and local regulations
All technicians opening the refrigeration circuit in
automotive air conditioning systems must now
be certified in refrigerant recovery and recycling
procedures to be in compliance with Section 609
of the Clean Air Act Amendments of 1990. For
information on certification call MACS Worldwide at
(215) 631-7020.
PURPOSE
The 24533 Air Operated Vacuum Pump is a Venturi-
type vacuum pump powered by compressed air and
designed for air conditioning service
The 1990 amendments to the United States Clean Air
Act mandate that all personnel who service refrigerant
systems must be trained and certified. Fines are
in place for violations and compliance is not being
monitored by the U.S. EPA.
Do Not Vent Refrigerant to the Atmosphere. Use
Appropriate Recovery Equipment.
This pump is designed to remove air and moisture
from an AC System. The system must be empty before
using this Vacuum Pump.
Do not connect to a system under pressure.
Any system found to be under pressure, by law must
be fully evacuated with approved recovery equipment.
Only after the system is completely emptied of all
refrigerant can the pump be used.
Note: Use a quick-disconnect fitting on the “Air Input”
fitting for fast, easy connections to the air supply
