Scope of these instructions These instructions describe the installation, commissioning, function and the operation of the mixed HeatBloC K33MAX DN 25. 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.
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].
The HeatBloC K33MAX is a preassembled group of fittings for heating circuits. The PAW HeatBloC is designed such that it can be directly mounted onto a PAW distribution manifold or a mounting plate. With transition connections, the HeatBloCs can also be mounted on modular distribution manifolds of other dimensions.
3 Product description 3.2 Function K33MAX - constant value control circuit with 3-way mixing valve and 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 constant flow temperature of the heating circuit.
3 Product description 3.2.1 3-way mixing valve with bypass [specialist] The 3-way mixing valve is a constant-value mixing valve for radiant panel heating systems (radiant floor heating, wall heating etc.) which are operated with a constant flow temperature and thus guarantee a basic heat supply. The desired flow temperature can be set at the rotary knob.

3 Product description Adjustable bypass 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 (normal operation). If the slot of the bypass screw is in a horizontal position, the bypass is completely open.

3 Product description Thermal control valve The thermal control valve keeps the flow line < T flow of the mixing valve completely open as long as the water from the flow line to the consumer is colder than the flow temperature set of the thermal control valve.

3 Product description Proceeding: 1. Take off the thermometer handles (A-2, F-2) and remove the insulating front shell. 2. Take the group of fittings out of the insulating back shell. 3. Dismount the mixing valve (C) and assemble it as described in the instructions of the conversion kit.
3 Product description 3.2.2 Check valve The heating circuit is equipped with a check valve (C-3, opening pressure 200 mm wc) in the return line of the mixing valve. The check valve can be opened. Operation During operation, the marking must be directed to "Z". ...
4 Assembly and installation [specialist] 4 Assembly and installation [specialist] The HeatBloC K33MAX can be mounted on a PAW modular distribution manifold or on a wall bracket. The modular distribution manifold and the wall bracket are optional accessories and are thus not included in the scope of delivery.
