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.

EXPERTS IN VACUUM PUMPS

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.
