5. การตั้งค่า

5.1 การแกะกล่อง

1. นำส่วนประกอบทั้งหมดออกจากบรรจุภัณฑ์อย่างระมัดระวัง
2. Inspect the pump and accessories for any signs of damage during transit. If damage is found, do not operate the unit and contact customer support.
3. ตรวจสอบให้แน่ใจว่ามีส่วนประกอบทั้งหมดที่ระบุไว้อยู่

5.2 การเติมน้ำมันปั๊มสุญญากาศ

The vacuum pump is shipped without oil. It is crucial to add vacuum pump oil before first use.

1. Locate the oil fill port on the top of the pump (usually marked 'OIL FILL' or similar).
2. ถอดฝาเติมน้ำมันออก
3. Slowly pour appropriate vacuum pump oil into the fill port until the oil level is between the 'MIN' and 'MAX' marks on the oil sight window. Do not overfill. The oil capacity is approximately 250 ml.
4. ปิดฝาเติมน้ำมันให้แน่น

5.3 Connecting the Manifold Gauge and Hoses

1. Connect the yellow hose to the vacuum pump's inlet port.
2. Connect the other end of the yellow hose to the service port (usually the center port) of the manifold gauge.
3. Connect the blue hose to the low-pressure side of the manifold gauge.
4. Connect the red hose to the high-pressure side of the manifold gauge.
5. Ensure all connections are finger-tight, then use a wrench to slightly tighten them to prevent leaks.

6. คู่มือการใช้งาน

6.1. การดำเนินการทั่วไป

1. Ensure the vacuum pump is placed on a stable, level surface.
2. Verify the oil level is correct in the oil sight window.
3. Connect the power cord to a suitable electrical outlet (220V/50Hz).
4. Turn on the power switch. The pump should start running smoothly.
5. Allow the pump to run for a few minutes to warm up and circulate the oil.

6.2 Evacuating an AC or Refrigeration System

This procedure outlines a typical evacuation process. Always refer to the specific service manual for the system you are working on.

1. Connect the blue hose from the manifold gauge to the low-pressure service port of the AC/refrigeration system.
2. Connect the red hose from the manifold gauge to the high-pressure service port of the AC/refrigeration system.
3. Ensure the manifold gauge valves (high and low side) are closed.
4. สตาร์ทเครื่องปั๊มสูญญากาศ
5. Slowly open both the high and low-pressure valves on the manifold gauge.
6. Monitor the vacuum gauge. Allow the pump to run until the desired vacuum level is reached (typically 500 microns or lower, depending on system requirements). This may take some time.
7. Once the desired vacuum is achieved, close both the high and low-pressure valves on the manifold gauge.
8. ปิดปั๊มสุญญากาศ
9. Observe the vacuum gauge for a period (e.g., 15-30 minutes) to ensure the system holds the vacuum, indicating no leaks.
10. After confirming no leaks, disconnect the hoses from the system and the vacuum pump.

7. การบำรุงรักษา

การบำรุงรักษาตามปกติจะช่วยให้ปั๊มสุญญากาศของคุณมีอายุการใช้งานยาวนานและมีประสิทธิภาพเหมาะสมที่สุด

7.1 การตรวจสอบระดับน้ำมันเครื่อง

Check the oil level before each use. The oil should be clear and between the 'MIN' and 'MAX' marks on the oil sight window. If the oil appears cloudy or discolored, it needs to be changed.

7.2 Changing Vacuum Pump Oil

Change the vacuum pump oil regularly, especially after evacuating systems with high moisture content or after prolonged use. Dirty oil reduces pump efficiency and can cause damage.

1. Ensure the pump is turned off and disconnected from the power supply.
2. Place a suitable container under the oil drain plug (located at the bottom of the oil reservoir).
3. Remove the oil drain plug and the oil fill cap to allow the old oil to drain completely.
4. ใส่ปลั๊กท่อระบายน้ำมันกลับเข้าที่อย่างแน่นหนา
5. Add new, clean vacuum pump oil through the oil fill port until the level is between the 'MIN' and 'MAX' marks on the sight window.
6. เปลี่ยนฝาเติมน้ำมัน
7. กำจัดน้ำมันเครื่องที่ใช้แล้วอย่างถูกวิธีตามระเบียบข้อบังคับของท้องถิ่น

7.3 การทำความสะอาดและการเก็บรักษา

• เช็ดภายนอกปั๊มด้วยผ้าสะอาดamp ผ้า. อย่าใช้สารเคมีหรือตัวทำละลายที่รุนแรง
• Store the pump in a clean, dry environment, preferably in its original carrying case, to protect it from dust and damage.
• Ensure all hoses and gauges are clean and properly stored.
