VEVOR 100 L/min HVAC Vacuum Pump 150W

Isingeniso

This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your VEVOR 100 L/min HVAC Vacuum Pump, Model TW-1K. Please read this manual thoroughly before using the product to ensure proper function and to prevent injury or damage.

Imiyalo yokuphepha

ISEXWAYISO: Ukwehluleka ukulandela le miyalo yokuphepha kungase kubangele ukushaqeka kukagesi, umlilo, noma ukulimala okubi kakhulu.

• Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating the vacuum pump.
• Qinisekisa ukuthi unikezwa amandla ngevolthitage matches the specifications on the pump's nameplate.
• Ungayisebenzisi ipompo ezimweni ezimanzi noma uyibeke emvuleni.
• Ensure adequate ventilation when operating the pump to prevent overheating.
• Never touch moving parts of the pump during operation.
• Nqamula ugesi ngaphambi kokwenza noma yikuphi ukulungisa noma ukulungisa.
• Use only VEVOR-approved vacuum pump oil. Mixing different types of oil can damage the pump.
• Gcina izingane kanye nabasebenzi abangagunyaziwe kude nendawo yokusebenza.
• Handle refrigerant hoses and connections with care, as refrigerants can cause frostbite.

Setha

1. Ukuqaqa kanye Nokuhlola

Carefully remove all components from the packaging. Inspect the pump and accessories for any signs of damage during transit. If any damage is found, do not operate the unit and contact customer support.

2. Adding Vacuum Pump Oil

1. Beka isivalo sokugcwalisa uwoyela phezu kwepompo.
2. Khulula isikulufu bese ususa isivalo sokugcwalisa uwoyela.
3. Carefully pour the provided vacuum pump oil into the oil reservoir until the oil level is between the MIN and MAX marks on the oil sight glass. Do not overfill.
4. Shintsha isivalo sokugcwalisa uwoyela ngokuphepha.

3. Connecting the Manifold Gauge and Hoses

1. Connect the red hose to the high-pressure side (HI) of the manifold gauge and the system's high-pressure service port.
2. Connect the blue hose to the low-pressure side (LO) of the manifold gauge and the system's low-pressure service port.
3. Connect the yellow hose to the central service port of the manifold gauge and the vacuum pump's inlet. Use appropriate adapters (R134a or R410a) if necessary.
4. Qinisekisa ukuthi konke ukuxhumana kuqinile ukuvimbela ukuvuza.

Imiyalelo yokusebenza

1. Preparing for Evacuation

1. Ensure the vacuum pump is placed on a stable, level surface.
2. Confirm the oil level is correct in the pump's sight glass.
3. Connect the manifold gauge and hoses to the HVAC system and the vacuum pump as described in the Setup section.
4. Open both the high-pressure (red) and low-pressure (blue) valves on the manifold gauge.

2. Inqubo Yokuphuma

1. Plug the vacuum pump into a suitable electrical outlet.
2. Turn on the vacuum pump. The pump will begin to draw a vacuum on the HVAC system.
3. Monitor the manifold gauge. The pressure should drop steadily. Continue pumping until the desired vacuum level is reached (typically below 500 microns for HVAC systems).
4. Once the desired vacuum is achieved, close both the high-pressure (red) and low-pressure (blue) valves on the manifold gauge.
5. Vala iphampu yevacuum.
6. Observe the manifold gauge for a period (e.g., 15-30 minutes) to ensure the vacuum holds, indicating no leaks in the system.

3. Disconnecting the Pump

1. After confirming the vacuum holds, slowly open the manifold gauge's central service port (yellow hose connection) to release the vacuum from the hose connected to the pump.
2. Disconnect the yellow hose from the vacuum pump.
3. Proceed with charging the HVAC system as required.

Isondlo

1. Ukuhlola Izinga likawoyela

Regularly check the oil level using the oil sight glass. The oil level should always be between the MIN and MAX marks. If the oil appears cloudy or discolored, it indicates contamination and should be changed immediately.

Figure 5: Oil sight glass for monitoring oil level.

2. Changing Vacuum Pump Oil

Vacuum pump oil should be changed after every 10-20 hours of operation or if it appears contaminated. Contaminated oil reduces pump efficiency and lifespan.

1. Ensure the pump is off and unplugged.
2. Beka isitsha esifanelekile ngaphansi kwepulaki yokukhipha uwoyela.
3. Remove the oil drain plug and the oil fill cap to allow the old oil to drain completely.
4. Faka esikhundleni se-plug yokukhipha uwoyela.
5. Refill with new VEVOR vacuum pump oil through the oil fill port until the level is between MIN and MAX on the sight glass.
6. Lahla uwoyela osetshenzisiwe ngendlela efanele ngokwemithetho yendawo.

3. Ukuhlanza

Gcina ingaphandle lepompo lihlanzekile futhi lingenalo uthuli kanye nemfucumfucu. Sebenzisa isikhangisoamp cloth for cleaning. Do not use harsh chemicals or solvents.
