plied preassembled.
The "Regumat" is available with or without heating
circulation pump. The individual components of
the model without pump are supplied loosely con-

Remove supply (1) and return column (2) from the
insulation. Pull off the front insulation (4) and the
insertion block (3) and loosen the screw (7) of the
wall bracket (6).
Determine position of the station on the wall and
fix the wall bracket with the enclosed screws. Use
rear insulation as jig.
Mount rear insulation onto the wall bracket, hang
supply and return column into it and protect
against twisting by use of the locking plate (8) and
screw.
Attention: When installing conventional pumps
(asynchronous motors), use the blind cover in-
stead of the insertion block.
4.3 Check valve
The check valve prevents a gravity circulation of
the heating water when the pump is switched off.
Check valve
closed
The check valve is closed in operating position;
passage is only possible in flow direction.
When putting the system into operation and during
maintenance work (filling and flushing), the check
valve must be opened.
