Настройка

Follow these steps for initial setup before operating the vacuum pump.

1. Распакуйце і праверце: Асцярожна выміце ўсе кампаненты з упакоўкі. Праверце на наяўнасць пашкоджанняў пры дастаўцы.
2. Дадайце алей вакуумнага помпы:
   • Locate the oil fill cap on top of the pump.
   • Remove the cap and slowly pour the provided vacuum pump oil into the reservoir.
   • Monitor the oil level through the oil sight window. Fill until the oil level is between the 'MIN' and 'MAX' marks. Do not overfill.
   • Шчыльна закруціце вечка заліўной горлачкі алею.

3. Размяшчэнне: Place the vacuum pump on a firm, level, and dry surface. Ensure adequate ventilation around the pump.
4. Электрычнае падключэнне: Connect the power cord to a grounded electrical outlet that matches the pump's voltagэлектронныя патрабаванні.

Інструкцыя па эксплуатацыі

This section outlines the general procedure for using the vacuum pump with the manifold gauge set for HVAC/refrigeration systems. Always refer to the specific service manual for the equipment you are working on.

1. Падрыхтуйце сістэму: Ensure the HVAC/refrigeration system is depressurized and all service ports are accessible.
2. Connect Manifold Gauge:
   • Connect the blue hose (low pressure) to the low-side service port of the system.
   • Connect the red hose (high pressure) to the high-side service port of the system.
   • Connect the yellow hose (service hose) from the manifold gauge's central port to the vacuum pump's inlet port.

3. Open Manifold Valves: Fully open both the high-side and low-side valves on the manifold gauge set.
4. Start Vacuum Pump: Turn on the vacuum pump. The pump will begin to evacuate air and moisture from the system.
5. Манітор вакууму: Observe the low-pressure gauge on the manifold. The needle should drop into the vacuum range. Continue running the pump until the desired vacuum level is achieved, typically for a specified duration based on system size and conditions.
6. Isolate Pump: Once the desired vacuum is reached, close both the high-side and low-side valves on the manifold gauge set. Then, turn off the vacuum pump.
7. Vacuum Hold Test: Allow the system to sit under vacuum for a period (e.g., 15-30 minutes) and monitor the gauge. If the vacuum holds steady, the system is leak-free. If the pressure rises, there may be a leak that needs to be addressed.
8. Адключыць: After a successful vacuum hold test, slowly open the manifold valves to release the vacuum from the hoses, then disconnect the hoses from the system and the pump.

Тэхнічнае абслугоўванне

Regular maintenance ensures optimal performance and extends the lifespan of your vacuum pump.

• Замена алею: Vacuum pump oil should be changed regularly, especially if it appears cloudy, discolored, or contaminated.
• To Change Oil:
  1. Ensure the pump is off and cool.
  2. Place a suitable container under the oil drain plug (usually located at the bottom or side of the pump).
  3. Remove the oil drain plug and the oil fill cap to allow the old oil to drain completely.
  4. Replace the drain plug and refill with new, clean vacuum pump oil as described in the 'Setup' section.
• Уборка: Keep the exterior of the pump clean and free of dust and debris. Ensure the cooling fins and fan area are clear for proper airflow.
• захоўванне: When not in use, store the pump in a dry, clean environment. Ensure the oil is at the correct level before storing for extended periods.
