Installation - oventrop Regumat S-130 Installation And Operating Instructions Manual

6 Installation

Installation, initial operation, maintenance and repair
are to be carried out by a specialist installer. (EN 5011
part 1 and VDE 1000 part 10 for work on electrical in-
stallations).
Observe warning advice under paragraph 2 (safety
notes)
WARNING
Before starting work, make sure that the pipework
and components have cooled down and been
drained.
Before starting work, disconnect electrical com-
ponents (controllers, pumps, etc.) from power
The pipework has to be flushed thoroughly before in-
stalling the "Regumat" connection group. Installation
is possible in any position (horizontal, oblique or verti-
cal in ascending or descending sections). It is impor-
tant to note that the direction of flow must conform to
the arrow on the assembly.
After all work has been completed, check all installation
points for leaks.
6.1 Change of supply and return
Installation of the supply pipe on the left hand side is
carried out as follows:
– Unscrew flanged pipe with check valve on the return
(left hand side of the pump group) and screw it back
on the right hand side.
– Install pump on the left hand side.
– The switching box of the pump must be turned to 3
o'clock position. To do so, loosen the hexagon
screws and turn the pump head by 180° so that the
switching box of the pump is in 3 o'clock position.
Now tighten 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 is not required.
6.2 Use of high-efficiency pumps
The product groups "Regumat" are suitable for use
with standard high-efficiency pumps.
TTENTION
A modification of the thermal insulation is not per-
missible. The pump motor must not be covered.
The maximum fluid temperature must be obser-
ved
The high-efficiency pumps are electronically controlled
and offer different settings. The pump setting should
be chosen depending on the application.
The following settings are recommended by the pump
manufacturers:
Application radiator heating (two pipe system)
– Automatic setting; alternatively
– ∆p-v Differential pressure variable
Application radiator heating (one pipe system)
– ∆p-v differential pressure variable
6.3 Installation of the actuator ("Regumat M3 / M4")
TTENTION
Contrary to the three-way mixing valve, the actua-
tor is turned around by 180° when mounting it
onto a four-way mixing valve.
– Mount antirotation device (1) onto the valve body.
– Push adapter (2) onto the spindle of the mixing valve
(3) until stop. Ensure flat surfaces on spindle and
adapter are aligned
– Set spindle of the mixing valve in such a way that
the nose of the adapter points downwards in the
direction of the axis of the connection thread. In this
position, the supply is closed by the spindle of the
mixing valve (bypass fully opened, cold).
– Place actuator (4) onto the shaft of the mixing valve.
– Place rotation indicator (5) onto the actuator as
illustrated.
– Slip handle for manual setting (6) onto the shaft of
the mixing valve with the arrow being in the blue
zone (factory setting: Anticlockwise sense until stop,
operating position "A" automatic operation).
– Introduce and tighten screw (7) together with the
serrated lock washer.
