How to Refill Refrigerant: A Step-by-Step Guide
Entrance
Refrigerants are vital to the efficient operation of air conditioning and cooling systems. However, when refrigerant levels drop, refilling requires care and expertise. Improper refilling can reduce system efficiency or cause serious damage.
In this article, we explain step by step how to fill the refrigerant gas and highlight the points that need to be taken into consideration.
1. When is Gas Refilling Required?
✔️ If cooling performance has decreased
✔️ If the system is running continuously but the environment is not cooled enough
✔️ If there is ice in the pipes
✔️ If the gas pressure is low during service checks
If these symptoms are present, the gas level should be checked.
2. Preparation and Security Measures
✅ Before starting the filling process:
✔️ The device must be turned off and the power supply must be disconnected.
✔️ Protective glasses, gloves and masks must be worn
✔️ The environment must be well ventilated
✔️ The type of gas to be used must be compatible with the device.
3. Equipment Required for Filling
🔧 Manifold set (hose set with pressure gauge)
🔧 Vacuum pump
🔧 Gas cylinder and weighing device
🔧 Gas detector (for leaks)
4. Gas Filling Step by Step
1️⃣ Purge the system: The old gas must be completely evacuated.
2️⃣ Apply vacuum: Moisture and air inside the system are removed.
3️⃣ Start gas filling: Gas is added in a controlled manner using the scale in the amount recommended by the device.
4️⃣ Check the pressure: Ideal pressure levels are verified with a manometer.
5️⃣ Perform a leak test: Check for leaks with foam or detector.
6️⃣ Start the system: The device is rebooted and its performance is monitored.
5. Most Common Mistakes
🚫 Confusing the type of gas
🚫 Excessive gas pressure
🚫 Direct filling without vacuum
🚫 Not using a scale
🚫 Filling by unauthorized persons
6. Max Gas Recommendation
