Enstalasyon ak Enstalasyon

This section provides general guidelines for installing the Danfoss RA-N 15 1/2 valve body. Professional installation is highly recommended.

Prepare sistèm lan: Turn off the main heating system and allow it to cool down. Isolate the radiator by closing any existing valves and drain the water from the radiator or the entire system if necessary.
Retire ansyen valv la (si sa aplikab): Carefully unscrew and remove the old radiator valve. Be prepared for residual water.
Prepare Koneksyon yo: Ensure the radiator and pipe connections are clean and free of debris. Apply appropriate thread sealant (e.g., PTFE tape or pipe sealing compound) to the valve threads.
Enstale kò valv la: Screw the Danfoss RA-N 15 1/2 valve body onto the radiator inlet connection. Ensure it is oriented correctly for an angle connection. Tighten securely using a suitable wrench, but do not overtighten.
Connect Pipework: Connect the heating system pipework to the other end of the valve body. Ensure all connections are watertight.
Ranpli ak senyen: Once the valve body is installed, refill the heating system and bleed any air from the radiators and pipework. Check for leaks at all connections.
Install Thermostatic Head: Once the system is refilled and checked, remove the white protective cap from the valve body. Install a compatible Danfoss RA thermostatic radiator valve head onto the valve body according to the head's instructions.

Enstriksyon Operasyon

The Danfoss RA-N 15 1/2 valve body itself does not have user-adjustable controls. Its operation is entirely dependent on the thermostatic radiator valve (TRV) head that is mounted onto it. Once a compatible TRV head is installed, you can control the temperature of the room by adjusting the setting on the TRV head. The valve body will then regulate the flow of hot water into the radiator based on the room temperature and the TRV head's setting.

Refer to the instruction manual of your specific Danfoss TRV head for detailed operating instructions, including temperature settings and frost protection features.

Antretyen

The Danfoss RA-N 15 1/2 valve body is designed for long-term, maintenance-free operation. However, general heating system maintenance practices should be followed:

Verifikasyon Sistèm Regilye: Periodically check your entire heating system for leaks or unusual noises.
Bleeding Radiators: Bleed radiators regularly to remove trapped air, which can affect heating efficiency.
Netwayaj: Keep the exterior of the valve body clean. Do not use abrasive cleaners or solvents.
Pwoteksyon Frost: If the heating system is to be shut down for an extended period during cold weather, ensure adequate frost protection measures are in place for the entire system to prevent freezing and damage to pipes and components.

Depanaj

Most issues related to radiator heating are often due to the thermostatic head or general system problems rather than the valve body itself. However, here are some common scenarios:

Pwoblèm	Kòz posib	Solisyon
Radiator not heating up	TRV head stuck or set too low; air in radiator; system pressure too low.	Check TRV head setting; try to free the pin on the valve body (gently push down); bleed radiator; check system pressure.
Radiator always hot	TRV head not closing valve; valve pin stuck open.	Ensure TRV head is correctly installed and functioning; gently try to push the valve pin down to ensure it moves freely.
Flit nan koneksyon yo	Improperly tightened connections; insufficient thread sealant.	Turn off water supply, drain, and re-tighten connections with proper thread sealant. If problem persists, consult a professional.

If you are unable to resolve an issue, it is recommended to contact a qualified heating engineer.
