It features durable construction and clear, easy-to-read gauges for accurate pressure and temperature measurements.
2. معلومات السلامة
تحذير: Always follow proper safety procedures when working with refrigerants and pressurized systems. Failure to do so can result in serious injury or equipment damage.
- ارتدِ معدات الحماية الشخصية المناسبة، بما في ذلك نظارات السلامة والقفازات، عند التعامل مع مواد التبريد.
- 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.

5. الإعداد
- فحص المكونات: Before each use, inspect the manifold, gauges, and hoses for any signs of damage, wear, or leaks. Ensure all connections are clean.
- Connect Hoses to Manifold:
- قم بتوصيل أحمر hose to the high-side port (typically on the right, marked "HIGH" or "H") of the manifold.
- قم بتوصيل أزرق hose to the low-side port (typically on the left, marked "LOW" or "L") of the manifold.
- قم بتوصيل أصفر hose to the center service port (typically marked "SERVICE" or "VAC/CHARGE") of the manifold.
6. تعليمات التشغيل
This section outlines general procedures. Always refer to the specific equipment manufacturer's service manual for detailed instructions and refrigerant charge specifications.
6.1. اختبار الضغط
- تجهيز النظام: Ensure the refrigeration or AC system is off and depressurized if necessary, following manufacturer guidelines.
- الاتصال بالنظام:
- Connect the free end of the أحمر hose to the high-side service port of the system.
- Connect the free end of the أزرق 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.
- فصل الخراطيم: Carefully disconnect the hoses from the system service ports. Be prepared for a small release of refrigerant.
6.2. شحن المبردات
This procedure assumes the system has been properly evacuated.
- الاتصال بالنظام: 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 أصفر hose to the refrigerant supply tank. Ensure the tank valve is closed.
- Purge Air from Yellow Hose:
- 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.
- Charge Refrigerant:
- 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.
- ملحوظة: 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.
- أغلق الصمامات وافصلها:
- 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. الصيانة
- تنظيف: 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.
- فحص الخرطوم: Regularly inspect hoses for cracks, cuts, or signs of wear. Replace damaged hoses immediately to prevent refrigerant leaks.
- معايرة المقياس: 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.
- تخزين: Store the manifold and hoses in a clean, dry place, protected from extreme temperatures and direct sunlight.
8. استكشاف الأخطاء وإصلاحها
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| تسرب المبرد | 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. |
