႑Install the temperature sensors with cable ties with
heat conducting paste.
NOTE
Sensor and communication cables must not be
placed near power cables.
Suitable flows/solar panel area
Recommended flow is 50 l/h per m2solar panel area.
Valve connections
Connecting supplied solar docking pipe, T-coupling and
straight connector.
For new installation, go straight to point 6.
1. Set the heat pump switch to "0" and remove the
lower front cover.
2. Close the shut off valves for the flow line in the radi-
ator circuit (QM31).
3. Close the shut off valves for the return line in the
radiator circuit (QM32).
4. Release the pressure in the boiler by opening the
safety valve (FL2) carefully. (The knob is turned anti-
clockwise to open).
5. Drain the boiler through (FL2), set the vent valves
(QM20) in the open position for air supply.
6. Remove the existing connector (XL8) and install the
supplied solar docking pipe, and then the supplied
straight connector.
7. Replace angled connector (see image below), on
which the expansion tank is connected with the T-
coupling supplied.
8. Connect the incoming pipe from the accumulator
tank to the solar docking pipe (XL8), and the return
pipe to the free connection in the T coupling.
