EXPERTS IN VACUUM PUMPS
As a specialized enterprise in making vacuum pumps, we have devoted ourselves to
satisfy our customers’ need for high quality products. We adopt the latest designs and
technology to make sure that our products not only use less energy, produce less noise
and last longer but also to ensure that they have the best design for the environment
and for reducing pumped gas pollution. Excellent design and production will bring you
more convenience.
1. Pump Use
ATD vacuum pumps are designed to obtain vacuum by pumping gas from sealed
containers. They are suitable for use with R12, R22 and R134a air conditioning
systems, as well as medical appliances, printing machinery and vacuum packing.
They can be continuously used at 5℃to 40℃
2. Features
Oil Anti-flowback Design
The gas inlet is specially designed to prevent the oil from flowing back, preventing the
container being pumped as well as the hoses from becoming polluted.
Environmental Design
The tank has separating devices at the exhaust port to prevent oil-spraying and to
reduce pollution.
Aluminum Alloy Casing
The ATD vacuum pump is manufactured with an aluminum alloy casing.
Because aluminum has good heat dissipation qualities, it will help to keep the pump
running more efficiently for a longer period of time.
Overall Design
The electric machinery and the pump are designed to make the product compact and
lighter.

Easy to start, Faster to pump
The starter design makes the ATD vacuum pump easy to start even in lower
temperatures. This feature allows higher efficiency and faster pumping.
Low Noise and Vibration
An elastomeric coupling insert between the motor and module results in extremely
quiet and smooth operation.

4. User’s Manual
·Examine the oil-level before using to make sure the oil-level is not lower than the
oil-level line in the sight glass. DO NOT RUN PUMP WITH LOW OIL LEVELS. Add
oil to bring it up to the oil level line. This pump uses high-speed vacuum oil HFVM200
or equivalent.
·Connect the container to be pumped to the gas inlet. The hose should be short,
sealed and free of dust, dirt and heavy condensation. Check for leaks before
operating pump.
·Take off the exhaust cap, plug in the power supply and turn the switch to the on
position.
·Unplug the vacuum pump, remove the connecting hoses and cover the exhaust cap
and oil plug after using.
5. Cautions
·Don’t pump flammable, explosive or poisonous gases.
·Don’t pump gas that can corrode metals and exert chemical charges.
·Don’t pump gas containing any dust or moisture.
·The temperature of the pumped gas shouldn’t be over 80℃and the room
temperature should be around 5℃to 40℃
·Don’t use vacuum pump as a compression pump.
·Pump cannot be run without oil
·The operating voltage is between 110V to 115V, 60Hz. You must use a grounded

EXPERTS IN VACUUM PUMPS
outlet.
·When unplugging the pump, pull the plug. Don’t unplug unit by pulling on the wire.
·Keep electrical cord free from all shop equipment, and do not let pump hang by
power cord
·Don’t use damaged plug or outlet.
·Don’t plug or pull out the plug with wet hands.
·Don’t plug unit in, unplug unit or use switch if there are any flammable or explosive
gases present.
·Always Unplug unit before disassembling.
6. Installation
·When in use, the pump should be horizontal and should be positioned where it is dry,
ventilated and free of dust and other contaminants.
·In order to ensure proper air flow, you must maintain a clearance around the pump of
at least 5 cm (2 inches).
·To permanently mount the vacuum pump, remove the rubber pads from the bottom
of the base, and use the existing threaded holes to mount unit. Connect with M4x12
screw and M4 nut. When permanently mounting this pump, be sure to maintain
proper clearances around the unit, especially at the air intake in the end of the vane
shell.
·If a special electromagnetic valve is needed, it can be installed on the gas inlet.
7. Troubleshooting

EXPERTS IN VACUUM PUMPS
Problem Possible Cause Correction
Low Degree
of Vacuum 1. Lack of oil
2. Oil is not clean
3. The oil inlet is blocked
4. The hoses or gas inlet are
clogged
5. The pump is not suitable for
your application
1. Add oil to above the oil level line
2. Change the oil
3. Clean the oil inlet or clean the filter
4. Check the connecting pipes
5. Get suitable pump for your
application
Oil Leaks 1. The oil seal is damaged
2. The housing gasket is loose
or worn out
1. Change oil seal
2. Change the housing gasket
Oil Spray 1. Too much oil
2. The pressure at the gas inlet
is too high or it has pumped
too much
1. Oil to the oil-level line
2. Change to a bigger pump
Starting
Difficulty 1. The oil temperature is too low
2. Electrical malfunction
3. Foreign matter is in the pump
1. Start the pump several times to try
to heat the oil
2. Check and have it fixed
3. Check and remove it
8. Maintenance
·Keep the pump clean and prevent foreign matter from entering.
·Keep the oil filled to the full level. Don’t let pump run without oil.
·Keep the oil clean. If the oil becomes dirty, muddy, or water or other volatile
substance gets in, it will affect the performance of the pump and the oil should be
replaced. Before replacing the oil, start the pump and have it run for about 30 minutes
to make the oil thin. Stop the pump and drain the oil from the oil drain plug. At this
time, open the gas inlet to release any pressure inside the pump. This will allow the
oil to drain more freely. After making sure the pump is clean, put the drain plug back in

EXPERTS IN VACUUM PUMPS
and then fill the pump oil to the oil-level.
·To store the pump when not in use for long periods of time, cover the oil cap and
exhaust cap and store it in a dry place.
·Repair of pump should only be done by experienced repair facilities.
