Safety Advice

Ensure you have read and fully understood the instruction manual and safety advice before using this product.

Only qualified persons should install this product. Improper installation may result in malfunction, water damage, or personal injury.
Ensure the heating system is fully isolated, drained, and depressurised before installation, inspection, adjustment, or removal of the valve.
Allow the system and valve to cool fully before handling to prevent burns or injury.
Confirm compatibility of the valve with the radiator type and heating system specifications prior to installation. Do not attempt to adapt or force-fit incompatible components.
Verify that the correct thread type and size are used. Do not connect mismatched threads as this may cause failure or leakage.
Hand-tighten connections initially, then secure using appropriate tools. Do not overtighten, as excessive force may damage threads, seals, or the valve body.
Ensure all connections are correctly aligned, sealed, and tightened to prevent leaks and potential water damage.
Do not remove or loosen the valve while the system is pressurised, as this may result in sudden water discharge and serious injury.
Do not subject the valve to impact, dropping, or mechanical shock, as this may cause cracking or structural failure.
Operate the valve only within the specified temperature and pressure limits. Exceeding these limits may result in failure or hazardous conditions.
Be aware that the valve body may become hot during operation. Avoid direct contact to prevent burns, particularly for children.
Keep children away from the valve and do not allow them to play with or adjust it. Supervise children in areas where the valve is installed.
Keep all detachable components, including caps, securely fitted and out of reach of children to prevent choking hazards.
When adjusting the valve, use the provided grip and turn gently. Do not apply excessive force to avoid strain injuries or product damage.
Avoid frequent or forceful adjustment cycles, as this may accelerate wear and reduce product lifespan.
Follow all usage instructions carefully. Do not tamper with factory settings.
Ensure the valve is not obstructed by furniture, curtains, or coverings, as this may impair temperature sensing and performance.
Be aware that prolonged use and pressure fatigue may weaken the product over time. Replace the valve at recommended service intervals or if wear is evident.
Avoid prolonged skin contact with metal surfaces if sensitive to nickel or plated materials, and wash hands after handling.
Ensure the radiator and associated pipework are securely fixed and stable to prevent stress on the valve connections.
Dispose of all packaging materials safely, keeping them away from children to avoid suffocation or injury hazards.
Replace the product immediately if any faults, damage, or irregular performance are observed, and use only manufacturer-approved replacement parts.

Parts

Thermostatic Head

BSP Valve Tail

15mm Compression

Nuts

Lock Shield Valve

1. Step 1 - Fitting the Thermostatic Head

Connect the thermostatic head to the flow (inlet) side of the radiator.
Turn the handle to reveal the calibration marks denoting the temperature at which the radiator will be turned off.
When the handle is turned fully clockwise, the valve operates will be fully shut off.
Screw the BSP valve tail into the radiator using a suitable sealant or tape.
When fitting the 15mm compression to the copper pipe, tighten the nut onto the olive to form the seal.

Please note:

Do not overtighten the handle or valve tail.
Do not cover the valve and keep it free from dust.

2. Step 2 - Fitting the Lock Shield Valve

Connect the lock shield valve to the outlet (return) side of the radiator, this will regulate the flow of the radiator.
Use a key to adjust the flow.
Balance the radiator to ensure a uniform temperature throughout.
Screw the BSP valve tail into the radiator using a suitable sealant or tape.
To fit the 15mm compression to the copper pipe, tighten the nut onto the olive to form the seal.

Please note:

Do not overtighten the valves and screws.

1. Maintenance

Regularly inspect for signs of corrosion, visible cracks, deformation, or damage both internally and externally. Keep the valve clean and dry to minimise deterioration.
Regularly check for water leaks at all joints and connections. If a leak is detected, isolate the system and consult a qualified technician immediately.
Do not use cleaning solvents, abrasives, or corrosive chemicals on the valve surface. Use a soft, damp cloth to clean.
Store the product in a dry, clean, temperature-controlled environment prior to installation, and protect it from physical damage and contamination.
Inspect the valve body. Replace immediately if any defects are identified.
