INFORMATION
Comply with the instructions for the water connection (see
Water connection) and water quality (see ).
1 Connect the filling hose ( Fig. 7-2 , item 1) with the non-return
valve (1/2") and an external pressure gauge (on the building
side) to the combined filling and draining valve (
Fig. 7-2 , item 2)
and secure it against slipping off with a hose clamp.
2 Connect the drain hose to the vent valve, and route it away from
the device. Open the vent valve with the hose connected; check
to make sure that the other vent valve is closed.
3 Open the water tap ( Fig. 7-2 , item 4) on the feed pipe.
4 Open the combined filling and draining valve ( Fig. 7-2 , item 2)
and monitor the pressure gauge.
5 Fill the system with water until the external pressure gauge
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 vent valve as soon as water emerges free of
bubbles.
7 Close the water tap ( Fig. 7-2 , item 4). The combined filling and
draining valve must remain open in order to read off the water
pressure on the external pressure gauge.
8 Switch on the power supply to the Daikin Altherma EHS(X/H).
9 On the RoCon+ HP controller, select the "Heating" operating
mode in the "Operating mode" menu [→ Main menu → Operat-
ing mode].
– After the start phase, the Daikin Altherma EHS(X/H) runs in
hot water heating operation.
10 Constantly check the water pressure on the external pressure
gauge during hot water heating mode, and top up water via the
combined filling and draining valve (
Fig. 7-2 , item 2) if neces-
sary.
11 Vent the entire heating system as described in Chap. 5.1.3
(open the system's control valves. At the same time, the under-
floor heating system can be filled and flushed by the underfloor
distributor.
12 Again check the water pressure on the external pressure gauge,
and top up water via the combined filling and draining valve (
Fig.
7-2 , item 2) if necessary.
13 Disconnect the filling hose ( Fig. 7-2 , item 1) with non-return
valve from the combined filling and draining valve ( Fig. 7-2 ,
item 2).
