4 Configuration

1 Connect the charge hose (item a) with the non-return valve
(1/2") and an external manometer (on the building side) to the
combined filling and draining valve (item b) and secure it
against slipping off with a hose clamp.
2 Connect the drain hose to the air purge valve, and route it away
from the device. Open the air purge valve with the hose
connected; check to make sure that the other air purge valve is
closed.
3 Open the water tap (item d) on the feed pipe.
4 Open the combined filling and draining valve (item b) and
monitor the manometer.
5 Fill the system with water until the external manometer shows
that the system target pressure is reached (system height +2 m;
1 m water column = 0.1 bar). The overpressure valve must not
actuate!
6 Close the manual air purge valve as soon as water emerges
free of bubbles.
7 Close the water tap (item d). The combined filling and draining
valve must remain open in order to read off the water pressure
on the external manometer.
8 Switch on the power supply of the indoor unit.
9 In the RoCon+ HP1 controller in the "Operating mode" menu,
