3. Kurulum ve Kurulum
3.1 Paketin Açılması ve Muayene
Carefully remove the vacuum pump from its packaging. Inspect the unit for any signs of shipping damage. If damage is found, contact your supplier immediately.
3.2 Elektrik Bağlantısı
The Robinair 15401 pump is designed for international use and can operate on 115V or 220-250V, 50/60Hz power. The unit may come pre-wired for 240V. Refer to the wiring diagram located on the motor for instructions on how to convert the wiring to 120V if necessary. If you are unsure about electrical wiring, consult a qualified electrician.
Ensure the power cord (not included, requires a suitable male electric cord) is securely connected and the power outlet is properly grounded. The pump requires a power cord capable of handling the necessary amperage for a 1/3 HP motor.
3.3 Yağ Doldurma
The pump is shipped without oil in the reservoir. Vacuum pump oil is included with the unit. To fill the oil:
- Locate the easy access oil fill port on top of the pump.
- Yağ doldurma kapağını çıkarın.
- Carefully pour the vacuum pump oil into the reservoir until the oil level is between the MIN and MAX lines on the sight glass. Do not overfill.
- Yağ doldurma kapağını sıkıca yerine takın.
3.4 İlk Kontroller
- Place the pump on a stable, level surface to ensure proper oil circulation and minimize vibration.
- Tüm bağlantıların sıkı ve güvenli olduğundan emin olun.
- Verify the Iso-Valve is in the closed position before starting the pump.
4. Kullanım Talimatları
4.1 Connecting to the System
Use appropriate vacuum-rated hoses to connect the pump's inlet fittings (1/4" or 1/2" male flare) to the A/C-R system's service ports. Ensure all connections are leak-free.
4.2 Tahliye Prosedürü
- Ensure the Iso-Valve is in the closed position.
- Turn on the vacuum pump. Allow it to run for a few seconds to stabilize.
- Slowly open the Iso-Valve to connect the pump to the system.
- Open the service valves on the A/C-R system to allow evacuation.
- Monitor the vacuum level using a reliable vacuum gauge. The pump is designed to achieve a deep vacuum of 15 microns.
- Using the Gas Ballast: If evacuating a system with significant moisture, open the gas ballast valve. This introduces a small amount of dry air into the pump, helping to prevent moisture condensation and improve the pump's ability to handle water vapor. Close the gas ballast valve once the system is mostly dry or when approaching the target vacuum level.
- Continue evacuation until the desired vacuum level is reached and held stable for a specified period, indicating thorough moisture removal.
4.3 Kapatma
- Close the service valves on the A/C-R system.
- Close the Iso-Valve on the pump. This isolates the pump from the system, preventing oil migration and maintaining the vacuum in the system.
- Vakum pompasını kapatın.
- Disconnect the hoses from the pump and system. Cap all ports to prevent contamination.
5. Bakım
5.1 Yağ Değişimi
Regular oil changes are crucial for the longevity and performance of your vacuum pump. Change the oil after every 10-20 hours of operation, or more frequently if the oil appears cloudy or discolored (indicating moisture contamination).
- Pompanın kapalı ve soğuk olduğundan emin olun.
- Place a suitable container under the angled oil drain valve.
- Remove the oil drain cap and the oil fill cap to allow air to enter and facilitate draining.
- Allow all old oil to drain completely. The angled design of the drain valve helps ensure a more complete draining.
- Yağ tahliye kapağını değiştirin.
- Refill with new, clean vacuum pump oil through the oil fill port, observing the sight glass to ensure the level is between MIN and MAX.
- Yağ doldurma kapağını değiştirin.
- Dispose of used oil according to local environmental regulations.
5.2 Temizlik ve Depolama
- Wipe down the exterior of the pump with a clean, damp Kumaş. Cilaya zarar verebilecek sert kimyasallar kullanmaktan kaçının.
- Keep the oil sight glass clean for accurate oil level monitoring.
- When not in use, store the pump in a clean, dry environment. Cap all inlet ports to prevent dust and contaminants from entering the pump.
