2.2 Possible dangers at the installation loca-
tion
DANGER
The pipework and the boiler connection
system can get very hot and lead to bad
scalding. Do not touch without safety gloves
and inactivate the system before work com-
mences.
2.3 Installation, initial operation, maintenance
Installation, initial operation, maintenance and re-
pairs have to be carried out by authorised and
qualified tradesmen.
(EN 5011 part 1 and VDE 1000 part 10 for work on
electrical installations).

Installation and assembly

4.1 Installation advice

DANGER
Before starting work, make sure that the pi-
pework and components have cooled down
and been drained.
Before starting work, disconnect electrical
components (controllers, pumps, etc.) from
power
The boiler connection system "Regumat" is sup-
plied pre-assembled.
The "Regumat" is available with or without circu-
lation pump. The individual components of the
model without pump are loosely connected.
Once the pump has been installed, the connecti-
ons have to be tightened with a torque of:
– Collar nut G 2
– Pump coupling

When leaving the factory, the supply pipe is on the
left hand side. But it can be changed (see 4.5).
4.2 Installation advice
The thermal insulation must be removed before in-
stallation. To do this, remove the middle block of
the insulation and then the front and rear insulation
shell.

4.3 Check valve

The check valve integrated in the return ball valve
prevents a gravity circulation of the heating water
if the pump is switched off. The check valve is clo-
sed in operating position and circulation 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. This is done by setting the
return ball valve to 45° with the help of the supplied
key (spanner size 19). For heating operation, the
return ball valve has to be opened again.
The ball valves feature a marking indicating the
flow (see illustr.).
