Putting the control unit into the service position

If required for commissioning and servicing, the control
unit can be put into a different position.

Fig. 54

Draining the boiler on the heating water side

Please note

Risk of scalding
Residual water will escape when the boiler or
one of the following components is fitted or
removed:

■

Water-filled pipework

■

Circulation pumps

■

Plate heat exchanger

■

Components fitted in the heating water or
DHW circuit.

Water ingress can result in damage to other
components.
Protect the following components against
ingress of water:

■

Control unit (in particular in the service posi-
tion)

■

Electrical components

■

Plug-in connections

■

Cables and leads

Only drain the boiler or heating system when the
boiler water or cylinder temperature has drop-
ped below 40 °C.
