5. セットアップ
5.1. Vacuum Pump Setup
- 配置: Place the vacuum pump on a stable, level surface in a well-ventilated area.
- オイル充填: Unscrew the oil cap. Carefully pour vacuum pump oil into the oil inlet until the oil level is between the MIN and MAX marks on the sight glass. Do not overfill.
- 電源接続: 電源コードをアース付き電源コンセント（110V/60Hz）に接続します。
- 初期チェック: Briefly turn on the pump to ensure it operates smoothly, then turn it off.

5.2. Digital Refrigerant Charging Weight Scale Setup
- バッテリーの取り付け: Open the battery compartment on the back of the LCD controller and insert a 9V DC battery (not included), observing polarity.
- 配置: Place the scale platform on a firm, level surface.
- コントローラー接続: Ensure the coiled cable from the scale platform is securely connected to the LCD controller.
- 電源オン: Press the 'ON/OFF' button on the LCD controller to power on the scale.
- Zero/Tare: Press the 'Z/T' button to zero the scale before placing any refrigerant tanks on it.
- ユニット選択: Press the 'UNIT' button to cycle through available units (kg, oz, lb).
6. 操作手順
6.1. Vacuum Pump Operation (System Evacuation)
- ホースを接続する: Connect the appropriate manifold gauge set hoses to the vacuum pump and the HVAC system service ports. Ensure all connections are tight.
- 開いているバルブ: Open the high and low side valves on the manifold gauge set.
- ポンプを起動します: Turn on the vacuum pump. Monitor the manifold gauges to observe the vacuum level.
- 避難時間: Allow the pump to run until the desired vacuum level (e.g., 500 microns or lower) is achieved and held steady for a specified period (consult HVAC system manufacturer specifications). The pump has a 30-minute duty cycle.
- バルブを閉じる: Once evacuation is complete, close the manifold gauge set valves before turning off the vacuum pump.
- 切断: Turn off the vacuum pump and disconnect the hoses.
6.2. Digital Refrigerant Charging Operation
- Prepare Scale: Power on the scale and ensure it is zeroed ('Z/T' button). Select the desired unit ('UNIT' button).
- タンクを配置する: Carefully place the refrigerant tank onto the center of the scale platform.
- 風袋重量: If the tank is not empty, press the 'Z/T' button to tare the weight of the tank, so the display shows 0.000. This allows you to measure the amount of refrigerant added or removed.
- ホースを接続する: Connect the appropriate manifold gauge set hose from the refrigerant tank to the HVAC system.
- チャージ/回復: Open the tank valve and the manifold gauge valve to begin charging or recovering refrigerant. Monitor the weight displayed on the scale.
- モニター： Stop the process once the desired amount of refrigerant has been transferred, as indicated by the scale reading.
- Close Valves & Disconnect: Close all valves and disconnect hoses.
