1. Utangulizi
This manual provides comprehensive instructions for the installation, operation, and maintenance of the Afriso Thermostatic Radiator Head Type 320 N. This head is specifically designed for use with Gampper clamp connection valve bodies manufactured between 1980 and 1998. It also serves as a direct replacement for older Afriso models 313 and 314.
2. Miongozo ya Usalama
- Ensure the heating system is depressurized and cooled before attempting any installation or maintenance procedures.
- Ikiwa hujui kuhusu mchakato wa ufungaji, inashauriwa kutafuta msaada kutoka kwa mtaalamu mwenye ujuzi.
- Do not expose the thermostatic head to ambient temperatures exceeding 50 °C.
- Keep the product out of reach of children to prevent accidental damage or misuse.
3. Bidhaa Imeishaview
The Afriso Thermostatic Radiator Head Type 320 N is a precision-engineered control head that utilizes a liquid sensor to regulate room temperature by modulating the flow of hot water through a radiator. Its robust design ensures reliable performance and energy efficiency.
Sifa Muhimu:
- Kihisi Kioevu: Highly responsive to ambient temperature changes for accurate control.
- Nafasi Sifuri: Allows for complete shut-off of the radiator, useful during warmer periods or for maintenance.
- Adjustable Economy Position: Enables setting a specific energy-saving temperature.
- Limitation Ring: Provides the ability to limit and lock the minimum and maximum temperature adjustment range.
- Nyenzo: Constructed from durable plastic for longevity.
- Muunganisho: Features a Gampper clamp connection for secure and compatible fitting.

4. Kuweka na Kuweka
Maagizo ya Ufungaji:
- Maandalizi: Verify that your radiator valve body is compatible with a Gampper clamp connection. This head is designed for valve bodies manufactured between 1980 and 1998.
- Ondoa Kichwa cha Zamani (ikiwa inafaa): If replacing an existing thermostatic head, carefully remove it according to its manufacturer's instructions.
- Nafasi: Align the new Afriso Thermostatic Radiator Head with the valve body. The head features a specific Gampper clamp connection mechanism.
- Inalinda: Gently push the thermostatic head onto the valve body. Ensure it is properly seated and then secure it firmly using the clamp connection. No tools are typically required for this step.
- Mpangilio wa Awali: Once installed, set the head to your desired initial temperature.

5. Maagizo ya Uendeshaji
The thermostatic head efficiently regulates the room temperature by automatically adjusting the flow of hot water through the radiator based on the ambient temperature.
Kurekebisha Joto:
- Kuweka joto linalohitajika: Rotate the handwheel on the thermostatic head to align the desired room temperature setting with the indicator mark. The scale typically ranges from '0' (off/frost protection) to '5' (maximum heat).
- Frost Protection (Snowflake Symbol): Setting the head to the snowflake symbol (often found between '0' and '1') activates frost protection. This maintains a minimum temperature in the room to prevent pipes from freezing, typically around 6-8 °C.
- Economy Position: Utilize the adjustable economy position to set a specific energy-saving temperature, which can help reduce heating costs.
- Limiting the Range: If desired, use the provided limitation ring (often consisting of red and blue clips, as shown in Figure 1) to restrict the minimum and maximum temperature settings. This prevents accidental changes outside a preferred range.
The integrated liquid sensor continuously monitors the ambient room temperature. If the room temperature falls below the set value, the valve automatically opens further to allow more hot water into the radiator, increasing heat output. Conversely, if the room temperature exceeds the set value, the valve closes, reducing the heat output and maintaining the desired temperature.

6. Matengenezo
Utunzaji na Kusafisha:
- Kusafisha: To clean the thermostatic head, simply wipe it with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the plastic surface.
- Epuka Kuzuia: Ensure that the thermostatic head's sensor is not covered by curtains, furniture, or any other objects. Obstructions can impair the sensor's ability to accurately read the ambient room temperature, leading to inefficient heating.
- Hakuna Matengenezo ya Ndani: The Afriso Thermostatic Radiator Head is a sealed unit and does not require any internal maintenance. Do not attempt to disassemble the head, as this will void any warranty and may damage the unit.
7. Utatuzi wa shida
Masuala ya Kawaida na Suluhisho:
| Tatizo | Sababu inayowezekana | Suluhisho |
|---|---|---|
| Radiator haina joto | Thermostatic head set to '0' or frost protection; valve pin stuck; air trapped in radiator. | Turn the head to a higher setting; gently press the valve pin to free it; bleed the radiator to release trapped air. |
| Room is too hot or too cold | Incorrect temperature setting; sensor obstructed; faulty thermostatic head. | Adjust the temperature setting; ensure the sensor is clear of obstructions; if persistent, the head may need replacement. |
| Thermostatic head is difficult to turn | Internal mechanism has become stiff or dirty. | Gently try to turn the head through its full range of motion a few times. If stiffness persists, consider replacing the head. |
