Electrical Safety:

• Electrical connection work must only be carried out by a skilled electrician in accordance with technical standards and regulations.

• To prevent electrical shock, always disconnect the pump from the power supply before performing any electrical connection, repair, or maintenance. Ensure the junction box cover is properly in place before running.

• The pump must be grounded, and the motor circuit must be equipped with a suitable rated motor protection switch before starting up.

Operational Safety:

• The pump surface and motor can become very hot during and after operation. Do not touch the pump until it has completely cooled down to avoid scalds.

• Do not place obstacles that could block ventilation around the motor, as this can lead to overheating, causing scalds or fire.

• The exhaust line must be unblocked before operating. Ensure gas flow from the exhaust port is not blocked or restricted in any way.

• The VALUE VP2200 vacuum pump is not suitable for pumping toxic, corrosive, flammable, or explosive gases.

• The pump is strictly prohibited from operating in an area with explosion hazards or flammable materials to prevent explosion or fire.

To ensure stable and reliable operation, the following environmental conditions must be met for both storage and operation of the VALUE VP2200:

• Working ambient temperature/humidity: 5-40°C, with humidity below 85% RH.

• Storage and Operating altitude: Less than 1000m.

• Storage and operating environment:

1. No corrosive, flammable, or explosive gases.

2. The pump must be stored in a room with good ventilation.

3. Avoid direct sunlight.

4. Keep far away from heat sources.

6. No frost.

The VALUE VP2200 series vacuum pump is a basic equipment in the vacuum application field, especially in researching, teaching, medical fields, and vacuum coating.

The pump can be used as the main pump for low/medium vacuum systems. It can also be used as a backing pump for roots pumps, diffusion pumps, molecular pumps, and other ultra-high vacuum systems.

Transportation:

• Handle with care during transportation as any negligence can cause pump damage.

• The pump must only be moved when it is stopped and the power supply is switched off.

• When lifting the pump, you must use the hook provided on the pump. Ensure it is securely fastened.

Installation Site:

• Choose a site that is suitable for installation, maintenance, and disassembly, has good ventilation, and allows for convenient electrical connection.

Installation Procedure:

• When connecting the pump to a vacuum system, place the pump horizontally on a flat and firm surface. Oblique installation may result in vibration, high noise, or damage.

Adding Oil:

• Open the oil fill plug and add the recommended vacuum oil according to the technical data. For the first time, add oil to the recommended oil level (MAX 80% mark).

• It is recommended to use VALUE company’s VPO series high-speed vacuum oil. Using other oil may cause unstable performance and affect the pump’s lifespan.

Before connection, check that the power supply is the same as the required power supply on the pump’s nameplate. Electrical work must be done by a skilled electrician.

For a pump with a single-phase motor:

The power supply cable, switch, and overload protector are all connected. The direction of rotation is fixed. The pump can be directly connected to a single-phase power supply using the provided cable and plug. The motor is protected by a thermal overload protector. If the thermal overload protector shuts off the pump, you must disconnect the plug from the power supply before performing any work. To restart, you should switch off, wait for it to cool, and then switch on again.

For a pump with a three-phase motor:

1. Open the junction box cover and connect the pump according to the provided wiring diagram.

2. You must use an appropriately rated cable and a suitably rated motor protection switch corresponding to the current rating on the motor’s nameplate.

3. Check if the motor rotation direction matches the arrowhead on the motor. If it is incorrect, immediately cut power and interchange any two phases of the connection (e.g., from W1, U1, V1) to correct the rotation.

4. To test the motor direction, open the inlet and exhaust ports. Place a slip of paper 50mm above the exhaust port and briefly switch the motor on and off. If the paper slip moves upward, away from the port, the direction is correct.

Follow these requirements for connecting the pump to a vacuum system:

• The connecting lines between the pump and the vacuum system should be as short as possible, with minimal corners.

• Ensure the diameter (DN) of the connecting line is the same as the pump’s intake port. Regularly check the inlet port filter and keep it clean.

• Ensure the diameter (DN) of the exhaust fitting is the same as the intake port. The exhaust line should preferably be installed with a downward slope to prevent condensate from flowing back into the pump. If the exhaust line has an upward slope, a condensate trap must be installed.

• Perform a leak check on the connection between the pipe and flange. A vacuum-tight connection is essential for the pump to achieve its ultimate vacuum.

• Never operate the pump with a blocked or constricted exhaust line.

Before Operating:

1. Ensure the exhaust line is unblocked.

2. Check that the oil capacity in the housing is at a suitable level.

3. Verify the running direction of the motor is correct.

4. Confirm the motor is well-grounded.

5. Check that the power supply matches the specifications on the pump.

Operating Procedure:

• For systems without condensable gases: The gas ballast valve knob should be switched off (to position C). Opening the gas ballast valve will cause the ultimate pressure to rise (vacuum level will decrease).

• For systems with condensable gases: If the system contains a small amount of condensable gas, open the gas ballast valve (to position I or II). This allows the pump to effectively handle a small amount of condensable gas. Once the system pressure has reduced to a certain value, close the gas ballast valve for normal operation.

Switching Off:

• Normal Shutdown: After finishing the pumping process under normal circumstances, the pump can be switched off directly. The inner anti-suckback valve will automatically switch off the air intakes, keeping the system clean.

• Long-Term Shutdown: If the pump will be stopped for a long time, cover the inlet and exhaust ports to prevent dust contamination.

• After Pumping Condensable Gas: Do not switch off the pump immediately. Keep the pump running for about 30 minutes with the gas ballast valve open and the intake line sealed to remove any dissolved gases from the oil.

Always disconnect the power supply and wait for the pump to cool down before any maintenance. The pump temperature can be very high just after stopping.

Oil Checking:

• Checking the Oil Level: During operation, the oil level must always be visible between the Min and Max marks on the sight glass. Add oil if the level is below Min, and discharge oil if it is above Max. The recommended liquid height is the best level.

• Checking Oil Quality: Normally, the oil is clear and transparent. If the oil darkens or becomes turbid, it should be changed.

When to Change the Oil:

• Change the oil if it contains a mass of liquid, organic solvents, or corrosive gases.

• Change the oil if the pump’s pressure performance declines over time.

• For a new pump, the first oil change should be after 100 operating hours.

• It is recommended to change the oil every 2000 operating hours under normal conditions.

Oil Change Procedure:

1. Ensure the pump is switched off and cooled down.

2. Remove the oil drain plug and let the used oil drain into a suitable receptacle.

3. When the oil flow stops, screw the drain plug back in. Briefly switch on the pump for a maximum of 10 seconds, then switch it off. This helps remove residual oil from the pump chamber.

4. Remove the oil drain plug again and drain the remaining oil.

5. Screw the oil-drain plug back in. Check the O-ring and replace it if necessary.

6. Remove the oil filling plug and fill with fresh oil to the correct level.

The dirt trap (inlet filter) can accumulate dust and grease, which can reduce pumping speed or cause blockages. To clean it, remove the dirt trap, clean it with a cleaning agent, blow it out with compressed air, and then re-install. Replace the dirt trap if it is defective.
