Danfoss RA-FN 15 Thermostatic Valve Instruction Manual

1. المقدمة

This manual provides instructions for the installation, operation, and maintenance of the Danfoss RA-FN 15 Thermostatic Valve, model 013G0003. This valve is designed for use with radiators, featuring an angle connection without pre-setting, and includes a 1/2 inch iron connection and tailpiece. Please read these instructions carefully before installation and use to ensure proper function and safety.

2. معلومات السلامة

Always observe general safety precautions when working with heating systems. Improper installation or maintenance can lead to property damage or personal injury.

• Ensure the heating system is depressurized and cooled before beginning any installation or maintenance work.
• ارتدِ معدات الحماية الشخصية المناسبة، مثل القفازات وحماية العين.
• إذا لم تكن متأكدًا من أي جزء من عملية التثبيت، فاستشر متخصصًا مؤهلًا.
• Do not exceed the maximum operating pressure or temperature specified for the valve.

3. الإعداد والتثبيت

3.1 الأدوات المطلوبة

• مفتاح ربط قابل للتعديل أو مفتاح ربط الأنابيب
• Thread sealant (e.g., PTFE tape or pipe dope)
• Bucket or towels for catching residual water

3.2 التحضير

1. Turn off the heating system and allow it to cool down completely.
2. Close the isolation valves for the radiator where the thermostatic valve will be installed. If no isolation valves are present, the entire heating system may need to be drained.
3. Drain any remaining water from the radiator by opening the bleed valve and loosening the existing valve connection.

3.3 خطوات التثبيت

The Danfoss RA-FN 15 valve is designed for an angle connection to the radiator. It includes a 1/2 inch iron connection and a tailpiece.

1. Remove the old valve from the radiator connection. Clean the threads thoroughly.
2. Apply thread sealant to the threads of the new Danfoss RA-FN 15 valve and the tailpiece.
3. Screw the tailpiece into the radiator inlet. Tighten firmly with a wrench, but do not overtighten.
4. Connect the main valve body to the tailpiece. Ensure the flow direction arrow on the valve body (if present) matches the direction of water flow into the radiator.
5. Connect the other end of the valve to the heating pipework. Tighten all connections securely to prevent leaks.
6. Once the valve is installed, slowly open the isolation valves (if closed) and then the bleed valve on the radiator to allow water to refill the system and release trapped air. Close the bleed valve once water flows steadily.
7. التحقق من جميع التوصيلات بحثًا عن التسريبات.

4. تعليمات التشغيل

The Danfoss RA-FN 15 is a thermostatic radiator valve designed to regulate the room temperature by controlling the flow of hot water through the radiator. This model does not feature pre-setting, meaning the maximum flow is determined by the system pressure and the valve's design.

4.1 تعديل درجة الحرارة

• To adjust the room temperature, rotate the thermostatic head (sold separately) attached to the valve.
• Typically, rotating the head clockwise decreases the temperature setting, and rotating it counter-clockwise increases it.
• The numbers or symbols on the thermostatic head correspond to different temperature levels. Refer to the specific instructions for your thermostatic head for precise temperature ranges.
• The valve automatically adjusts the water flow to maintain the desired room temperature, saving energy.

5. الصيانة

Regular maintenance ensures the longevity and efficient operation of your thermostatic valve.

• تنظيف: Periodically wipe the valve body and thermostatic head with a soft, damp القماش. لا تستخدم المنظفات أو المذيبات الكاشطة.
• التحقق من وجود تسريبات: Regularly inspect all connections for any signs of water leaks. Tighten connections if necessary, but do not overtighten.
• Valve Pin Movement: If the radiator remains cold even when the thermostatic head is set to a high temperature, the valve pin might be stuck. Remove the thermostatic head and gently press the pin several times to free it. If the issue persists, professional assistance may be required.
• فصل الشتاء: If the heating system is shut down for an extended period during cold weather, ensure the system is properly drained or protected with antifreeze to prevent freezing damage to the valve and pipes.
