It features durable construction and clear, easy-to-read gauges for accurate pressure and temperature measurements.
2. Güvenlik Bilgileri
UYARI: Always follow proper safety procedures when working with refrigerants and pressurized systems. Failure to do so can result in serious injury or equipment damage.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling refrigerants.
- Ensure adequate ventilation in the work area to prevent accumulation of refrigerant vapors.
- Never apply heat directly to refrigerant cylinders.
- Do not over-pressurize refrigeration systems. Refer to system manufacturer specifications.
- Always connect hoses securely before opening valves.
- Dispose of refrigerants and associated waste according to local environmental regulations.

6. Kullanım Talimatları
This section outlines general procedures. Always refer to the specific equipment manufacturer's service manual for detailed instructions and refrigerant charge specifications.
6.1. Basınç Testi
- Prepare System: Ensure the refrigeration or AC system is off and depressurized if necessary, following manufacturer guidelines.
- Sisteme Bağlan:
- Connect the free end of the kırmızı hose to the high-side service port of the system.
- Connect the free end of the mavi hose to the low-side service port of the system.
- Open System Valves: Slowly open the service port valves on the system to allow refrigerant pressure to reach the manifold gauges.
- Read Gauges: Observe the pressure readings on both the red (high-side) and blue (low-side) gauges. Compare these readings to the system manufacturer's specifications for the specific refrigerant (R-22, R-134A, or R-404A) and operating conditions.
- Close System Valves: Once readings are taken, close the system service port valves.
- Hortumları ayırın: Carefully disconnect the hoses from the system service ports. Be prepared for a small release of refrigerant.
6.2. Soğutucu Şarjı
This procedure assumes the system has been properly evacuated.
- Sisteme Bağlan: Connect the red and blue hoses to the high and low-side service ports of the system, respectively, as described in Section 6.1.
- Connect to Refrigerant Tank: Connect the free end of the sarı hose to the refrigerant supply tank. Ensure the tank valve is closed.
- Sarı hortumdan havayı boşaltın:
- Slightly open the refrigerant tank valve.
- Loosen the yellow hose connection at the manifold center port just enough to allow a small amount of refrigerant to escape, purging air from the hose.
- Retighten the yellow hose connection.
- Soğutucu Akışkan Dolumu:
- With the system running (if charging by pressure/superheat) or off (if charging by weight), slowly open the low-side (blue) manifold valve to allow refrigerant to flow into the system.
- Monitor the low-side gauge and the system's performance.
- Close the low-side manifold valve when the desired charge is achieved.
- Not: For liquid charging, the high-side valve may be used with the system off, or a liquid charging adapter may be required. Always follow system manufacturer guidelines.
- Close Valves and Disconnect:
- Close the refrigerant tank valve.
- Close both the high-side and low-side manifold valves.
- Close the system service port valves.
- Carefully disconnect the hoses from the system and refrigerant tank.
7. Bakım
- Temizlik: After each use, wipe down the manifold and hoses with a clean, dry cloth. Avoid using harsh chemicals that could damage the gauges or seals.
- Hortum Kontrolü: Regularly inspect hoses for cracks, cuts, or signs of wear. Replace damaged hoses immediately to prevent refrigerant leaks.
- Gösterge Kalibrasyonu: While Yellow Jacket gauges are factory calibrated for accuracy, if you suspect a gauge is inaccurate, it should be checked by a qualified technician. Do not attempt to recalibrate gauges yourself.
- Depolamak: Store the manifold and hoses in a clean, dry place, protected from extreme temperatures and direct sunlight.
8. Sorun Giderme
| Sorun | Olası Neden | Çözüm |
|---|---|---|
| Soğutucu sızıntısı | Loose hose connections, damaged O-rings, faulty hoses. | Tighten all connections. Inspect and replace O-rings or hoses as needed. Use leak detection fluid. |
| Inaccurate Gauge Readings | Gauge damage, improper connection, incorrect refrigerant scale selected. | Ensure proper connection. Verify correct refrigerant scale. If suspected damage, have gauges professionally checked. |
| Difficulty Charging/Evacuating | Manifold valves not fully open/closed, clogged hoses, system blockage. | Ensure manifold valves are fully actuated. Check hoses for obstructions. Consult system service manual for blockages. |
