1General Information
Carefully read these instructions before installation and commissioning.
Save these instructions in the vicinity of the installation for future reference.
1.1 Scope of these instructions
These instructions describe the function, installation, commissioning and operation of the
direct (unmixed) HeatBloC MC41 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.
The chapters called [specialist] are intended for specialists only.
1.2 Designated use
The HeatBloC may only be used in heating circuits taking into consideration the technical limit
values indicated in these instructions.
The HeatBloC must not be used in drinking water applications.
Improper usage of the HeatBloC excludes any liability claims.
Only use PAW accessories with the HeatBloC.
This product complies with the relevant directives and is therefore labelled with the CE mark.
The Declaration of Conformity is available upon request. Please contact the manufacturer.
The wrapping materials are made of recyclable materials and can be disposed of with
recyclable materials.

Safety instructions
2017/02 99453x013x-mub-en – V02 5
2Safety 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 following must be observed during installation and commissioning:
•relevant local and national regulations
•accident prevention regulations of the professional association
•instructions and safety instructions of this manual
CAUTION
Personal injury and damage to property!
The HeatBloC must only be used in heating circuits filled with heating water
according to VDI 2035 / Ö-Norm H 5195-1.
The HeatBloC must
not
be used in drinking water applications.
NOTICE
Material damage due to mineral oils!
Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant
properties get lost. We do not assume liability nor provide warranty for damage to property
resulting from sealants damaged in this way.
It is imperative to avoid that EPDM gets in contact with substances containing mineral
oils.
Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as
Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.

3Product description
The HeatBloC is a preassembled group of fittings for heating circuits. The integrated pump can
be isolated by means of ball valves and can thus be maintained without draining of the system.
The nominal value for the differential pressure between the flow and the return is adjusted at the
controller. On this basis, the controller regulates the pump. Thus, the hydraulic balancing at the
distribution manifold is assured and an energy-saving operation of the pump is guaranteed at
any time.
The PAW HeatBloC must be either installed on a PAW modular distribution manifold or a PAW
wall bracket.
For the function of a MC system, one connection set (wall power supply, item no. 1398700) is
necessary. The connection set is not included in the scope of delivery.

3.2 Function
MC41 – Direct HeatBloC
In the case of the direct or unmixed HeatBloC,
the flow of the heat generator is pumped directly
through the heating circuit.
Application range:
•Boiler charging
•Storage tank charging and discharging
•Radiators

3.3 Pump [specialist]
The pump can be completely isolated. It can be replaced and maintained without draining the
HeatBloC. Close the ball valves (A-2, C-1) above and beneath the pump.
The pump has been correctly adjusted at the factory. In the case of a breakdown of the control
(no PWM signal), the pump runs at maximum rotation speed. To assure a proper functioning of
the heating circuit, the pump must be set as follows:
•PWM profile (heating)
3.3.1 Pump settings Grundfos UPM3 Hybrid
The following code must appear on the pump display. The code can be verified by briefly
pressing the push button. Please observe the separate instructions of the pump!
Yellow

3.3.2 Pump settings Wilo-Yonos PARA RSTG
The rotary knob of the pump must be set to the following symbol.
The LED ring is illuminated in orange. Please observe the separate
instructions of the pump!

3.4 Check valve
The HeatBloC is equipped with a check valve in the return pipe. The check valve can be
opened manually.
Operation
During operation, the marking must be directed to "Z".
The check valve is closed.
Flow only in the direction of the arrow.
Filling, draining, venting
For filling, draining and venting the installation, the marking
must be directed to "A".
The check valve is open.
Flow in both directions.

4Change of the flow line [specialist]
1. Dismount the temperature sensors of the
ball valves (A-2 and F-2).
2. Unscrew both nuts of the sensor (G).
3. Unscrew the nuts of the ball valves (A-2
and F-2) above the pump or the return
pipe.
4. Mount the return ball valve above the
pump and the flow ball valve above the
return pipe.
5. Interchange the flow and the return line.
Please observe the position of the
opening mechanism of the check valve in
the return pipe (see figure).
6. Mount the sensor (G) between the ball
valves.
Attention:
The ground lug of the sensor
points forward. The banderole indicates
on which side of the sensor housing the
pump must be fixed (see figure on the
left).
7. Flatten the ground lug.
8. Mount the temperature sensors TRand TV
into the ball valves.
Observe the correct attribution:
Red = Flow
Blue = Return
