1. Pendahuluan
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. Informasi Keselamatan
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.
- Gunakan alat pelindung diri (APD) yang sesuai, seperti sarung tangan dan pelindung mata.
- Jika Anda tidak yakin tentang bagian mana pun dari proses instalasi, konsultasikan dengan profesional yang berkualifikasi.
- Do not exceed the maximum operating pressure or temperature specified for the valve.
3. Pengaturan dan Instalasi
3.1 Alat yang Diperlukan
- Kunci pas yang dapat disetel atau kunci pipa
- Thread sealant (e.g., PTFE tape or pipe dope)
- Bucket or towels for catching residual water
3.2 Persiapan
- Turn off the heating system and allow it to cool down completely.
- 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.
- Drain any remaining water from the radiator by opening the bleed valve and loosening the existing valve connection.
3.3 Langkah Instalasi
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.
- Remove the old valve from the radiator connection. Clean the threads thoroughly.
- Apply thread sealant to the threads of the new Danfoss RA-FN 15 valve and the tailpiece.
- Screw the tailpiece into the radiator inlet. Tighten firmly with a wrench, but do not overtighten.
- 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.
- Connect the other end of the valve to the heating pipework. Tighten all connections securely to prevent leaks.
- 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.
- Periksa semua sambungan untuk mengetahui ada kebocoran.

4. Petunjuk Pengoperasian
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 Penyesuaian Suhu
- 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. Pemeliharaan
Regular maintenance ensures the longevity and efficient operation of your thermostatic valve.
- Pembersihan: Periodically wipe the valve body and thermostatic head with a soft, damp kain. Jangan gunakan pembersih atau pelarut yang bersifat abrasif.
- Memeriksa Kebocoran: 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.
- Musim dingin: 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.
6. Penyelesaian masalah
| Masalah | Kemungkinan Penyebab | Larutan |
|---|---|---|
| Radiator tetap dingin | Valve pin stuck; air in radiator; thermostatic head set too low; system pressure too low. | Remove thermostatic head and gently press pin; bleed radiator; increase temperature setting; check system pressure. |
| Radiator is too hot | Thermostatic head set too high; valve not closing completely. | Decrease temperature setting; check valve pin for debris or damage. |
| Kebocoran air dari sambungan | Loose connection; insufficient thread sealant; damaged threads. | Tighten connections; reapply thread sealant; replace valve if threads are damaged. |
If troubleshooting steps do not resolve the issue, contact a qualified heating technician.
