6 Installation
The product group is supplied pre-assembled.
The pipework has to be flushed thoroughly before
installing the “Regumat” with heat meter. Installation
is possible in any position (horizontal, oblique or
vertical in ascending or descending sections).
However, it is important to note that the direction of
flow must conform to the arrow on the assembly.
Observe warning advice under paragraph 2 (safety
notes)!
!
– Do not use any lubricant or oil when installing
the valve as these may destroy the seals. If
necessary, all dirt particles and lubricant or oil
residues must be removed from the pipework
by flushing the latter.
– When choosing the operating fluid, the latest
technical development has to be considered
(e.g. VDI 2035).
– Please protect against external forces (e.g.
impacts, vibrations etc.).
CAUTION
!
6.1 Change of supply and return
Installation of the supply pipe on the left hand side is
carried out as follows:
– Unscrew heat meter with ball valve and distance
piece on the return (left hand side of the pump
group) and screw it back on the right hand side.
– Install pump with supply ball valve on the left hand
side.
The switch box of the pump must be turned to
3 o’clock. To do so, loosen the hexagon screws and
turn the pump head by 180° so that the switch box
of the pump is in 3 o’clock position. Now tighten
the hexagon screws and ensure that the pump head
is not jammed.
– Remove and interchange the red and blue plugs on
the front of the insulation.
Red = supply, blue = return
– A modification of the mixing valve (“Regumat M3”)
is not required.

“Regumat S / M3“ – Application radiator heating
(one pipe system)
– ∆ p-v - differential pressure variable
A modification of the thermal insulation is not
permissible. The pump motor must not be covered.
