Operating and installation instructions
31
The water connection set (accessories) included in the scope of supply comprises the following parts:
Water stop function
In the event of a serious defect (loose hose connection, broken water filter housing, etc.), the water stop automatically closes if a
pressure drop of a sufficient amount is detected. This can prevent uncontrolled water leakage.
For restoring the function:
1. Close water tap
2. Remove hose
3. Unscrew water stop
4. Press red button on the valve outlet side.
A water stop device does not offer 100 % protection against water damage. The tightness of the water connection must
therefore be checked at regular intervals.
12.7. Connection of the water heater battery
For versions with the hot water heater battery, the flow and return flow is integrated into the heating system. The circulating pump
and a 3-way mixing valve (available as accessory part) are connected on site. For a full humidification performance, the inlet temper-
ature must be at least 15 Kelvin higher than the desired air outlet temperature and must be constantly provided during the humidifi-
cation period.
With too low heating water temperatures, the humidity and air temperatures set may possibly not be reached.
