Connect the upper connection piece (M)
to the heat exchanger (HEL) and tank (DTA).
Insert the EPDM gaskets provided for this beforehand and
ensure horizontal alignment.
Once the connection has been successfully established, you
can rmly tighten the screws of the mounting bracket.
For the time being, manually tighten the screw connections
on the heat exchanger and tank.

Carefully insert the capillary of the industrial thermometer
(turn it back and forth) as far as it will go into the immersion
pocket of the upper connection
piece (M) provided for this purpose.
Then fasten the thermometer from below with the existing
screw in the thermometer housing.
Now mount the tank thermometer: Seal the 200 mm
stainless steel pocket with a suitable sealing tape in the
socket provided (see tank data sheet)
and then insert the thermometer.

Screw the lower ball valve to the cold water connection.
Insert the enclosed EPDM gasket in advance.
Then tighten manually.
Connect the lower connection piece (N), the balancing
valve (D) and the connection part (Q) together one after the
other and to the charging heat exchanger (HEL).
Check the correct ow direction of the balancing valve
(upwards - see arrow on the valve body).
Use enclosed EPDM gaskets and manually tighten all
screwed connections.
The safety valve is screwed onto the
designated port R ¾” as shown.
This connection is self-sealing
and requires no additional sealing material.

Now connection part (Q) and
charge pump (LPU) using the EPDM gaskets.
Notice! You should also ensure the correct
ow direction of the pump here (arrow pointing up).
Lastly, you can now screw the connecting pipe (R) between
the charge pump (LPU) and the lower ball valve (G) with the
appropriate EPDM gaskets inserted.

Now, if all components are positioned vertically/
horizontally and relatively stress-free, tighten all screw
connections using suitable tools.
Notice! Do not use pipe wrench pliers; for one thing,
the nuts will be damaged and there is also the danger of
excessive tightening, which can destroy the gasket.
EPDM gaskets do not require a high torque to ensure
tightness (~ 10 .. max. 35 Nm).
See also chapter 5.1 in the
installation and operating instructions
It is best to manually tighten all screw connections and
correct when lling the system only until the respective
connection no longer leaks.
