The most common hazards include electrical shock, fire, or explosion to pumping flammable, explosive or poisonous gases, or gases that can corrode metals and exert chemical charges. To avoid these hazards, always read and follow the instructions in this manual carefully before using your vacuum pump.

Instructions on how to handle the vacuum pump safely

To ensure the safe handling of your vacuum pump, please follow the guidelines:

◆ Never operate the pump without oil, as this can damage the pump create potential hazards.
◆ The temperature of the pumped gas should not exceed 80^ C, and environment temperature should be around 5^ C to 60^ C. This will prevent damage to the pump and ensure safe operation.
◆ Do not use the vacuum pump as a compression pump or convey pump, as this can cause damage to the pump and create potential hazards.
◆ The operating voltage for the pump is between 192 to 248V, 50H; Use a grounded outlet to prevent electrical shock.
When unplugging the pump, pull the plug. Do not unplug the unit pulling on the wire, as this can cause damage to the cord and potential hazards.
◆ Keep the electrical cord free from all shop equipment, and do not let the pump hang by the power cord to avoid damage to the cord prevent potential hazards.
◆ Do not use a damaged plug or outlet, as this can cause electrical shock or fire.
◆ Do not plug or unplug the unit with wet hands, as this can cause electrical shock.

◆ Do not plug the unit in, unplug it, or use the switch if there are flammable or explosive gases present. Always unplug the unit before disassembling it to avoid potential hazards.

Guidelines for handling hazardous materials

Your vacuum pump should not be used to pump flammable, explosive poisonous gases, or gases that can corrode metals and exert chemical charges. Additionally, do not pump gas containing any dust or moisture you need to handle hazardous materials, use proper personal protective equipment and follow all guidelines for safe handling and disposal of materials.

GETTING STARTED

Introducing the key features of the pump

◆ Dual-stage Rotary Vane Vacuum Pump with Gas Ballast:

The vacuum pump features a dual-stage rotary vane design with ballast. This feature reduces moisture corrosion of the machine an extends the life of the machine and oil.

◆ Copper Coil, Four-Pole Motor:

The pump is equipped with a copper coil and four-pole motor, with provides bigger torque for better starting and produces less heat, making it more durable.

◆ Die-Cut Aluminum Body and Ventilation Fan:

The vacuum pump features a die-cut aluminum body and a ventilator fan, which allows for easy heat dissipation and guarantees the performance stability of the pump.

◆ Anti-Flow Design:

The vacuum pump is designed with an auto anti-backflow valve a manual ball valve, which prevents backflow and allows for control the vacuum, preventing potential damage to the equipment.

◆ Connect the container to be pumped to the gas inlet using a sho sealed hose that's free of dust, dirt, and heavy condensation. Che for leaks before operating the pump.

◆ If your vacuum pump comes with an exhaust cap, remove it.

◆ Plug in the power supply and turn on the switch.

◆ After use, unplug the vacuum pump, remove the connecting hoses, and cover the exhaust cap (if it has one) to prevent oil spills. A cover the oil plug to keep the oil clean and prevent dirt from er the vacuum pump.

Installation

To ensure the proper functioning of the vacuum pump, follow these installation guidelines:

◆ The pump should be positioned horizontally and in a dry, ventilated area free of dust and other contaminants.
◆ Maintain a clearance of at least 10cm (4 inches) around the pump ensure proper airflow.
◆ If you are permanently mounting the pump, remove the rubber pad from the bottom of the base, and use the existing threaded holes mount the unit with ST4.2 screws.
When permanently mounting the pump, be sure to maintain proper clearances, especially at the air intake at the end of the vane sh
◆ If a special electromagnetic valve is needed, it can be installed or gas inlet.

Connecting the vacuum pump to the system being evacuated By following these guidelines and steps, you can effectively control the vacuum pressure and safely connect the vacuum pump to the system being evacuated.

◆ Identify the gas inlet on the vacuum pump and the gas outlet on system being evacuated.
◆ Use a short, sealed hose to connect the gas inlet on the vacuum to the gas outlet on the system being evacuated. Make sure the is free of dust, dirt, and heavy condensation.
◆ Check for any leaks in the connection before starting the pump.

Open the gas inlet and pump for 1-2 minutes while adding a small quantity of clean oil in gas inlet. This is to replace the residual oil from the inside of the After ensuring that the pump is clean, put the drain plug back in the clean pump oil from the gas inlet to the oil level.

◆ To store the pump when not in use for long periods of time, cow oil cap and exhaust cap (if applicable) and store it in a dry plac
◆ Repair of the pump should only be done by a qualified service technician.
