Page 4: General Information
These instructions describe the installation, commissioning, function and the operation of the mixed HeatBloC K34 DN 25 and DN 32. For other components of the installation, such as the pump, the controller or the modular distribution manifold, please observe the instructions of the corresponding manufacturer. -
Page 5: Safety Instructions
2 Safety instructions 2 Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist]. -
Page 6: Product Description
The pump can thus be maintained easily without draining the heating circuit. The HeatBloC is designed such that it can be directly mounted onto a PAW distribution manifold or a mounting plate. -
Page 7: Function
3 Product description 3.2 Function K34 3-way mixing valve with bypass 0-50 % The flow temperature of the heating circuit is controlled by the integrated mixing valve. Hot water from the boiler and cold return water are mixed to obtain the desired flow temperature. The mixing valve is adjusted via an external controller in combination with the electric actuator. -
Page 8: Check Valve And Non-Return Valve
3 Product description 3.2.1 Check valve and non-return valve The HeatBloC is equipped with a check valve (D-1, opening pressure 200 mm wc) in the return pipe and with a non-return valve (C-3, opening pressure 50 mm wc) in the return of the mixing valve. -

3 Product description 3.2.2 Pump [specialist] The pump can be completely isolated. It can be replaced and maintained without draining the heating installation. Isolation of the pump: 1. Disconnect the expansion tank from the installation. 2. Close the ball valves in the flow and the return (A-2, F-2). 3. - Page 10 3 Product description 1. During commissioning, determine the optimum bypass position for the operation of the installation through a trial-and-error process. If the slot of the bypass screw is in a vertical position, the bypass is closed. If the slot of the bypass screw is in a horizontal position, the bypass is completely open.
