Setting the temperature:

The head have a scale and symbols that correspond to the following room temperature setpoints:

* 1 2 3 4 5
Frost protection at 6C 12C 16C 20C 24C 28C

 

Mounting:

1. Connect the valve body with the inlet of radiators and pipes by following the flow direction arrow on the body. When filling the system, the thermostatic valves should be fully opened,

2. Unscrew and remove the protection cap from the thermostatic valve body.

3. Turn the thermostatic head lever to number 5.

4. Fit the thermostatic head to the valve body, screw on and tighten with a rubber jawed wrench(approx. 20 Nm)

5. Ensure that the setting arrow is pointing upwards and then set the head to number 3 or others

6. The most effective position is to have the head in a horiznotal position where the greatest efficiency will be obtained, as heat from the pipe will not effect the sensor. This is particularly important with top entry connections. With the bottom entry connections, we recommend the valves be fitted with the head work mounted vertically but where space is limited.

Correct installation and maximum performance will be achieved if:

7. The thermostatic head is not connected behind furniture, curtans or drapes, hidden under shelves, panelling or in a recess where air pockets can occur. The thermostatic head is not exposed to direct sunlight or draughts.

Maintenance:

Removal of the valve insert is achievable while the system is live and under full working conditions by using the fitting tool.

Storing:

1- Storage environment temperature should be no more than 50C.

2- During the night, it is recommended to place it at lower position in order to save energy and provide better comfort.

3- The anti-frost position () used to avoid room temperature falling under 0 C. When people out or not at home, it is recommended to place it at position() in order to the anti-frost protection operates only when the boiler is working.

4- Thermostat and accessories should be kept under a dry and ventilat condition with no contact of corroive media indoor.
