7.2.4 Priming
Before withdrawing water from the rainwater storage tank for the first time, the
mains water storage tank must be filled with water. It is filled automatically when
the operating mode selector switch is set to
mains water mode
for approx.
15 seconds and the power plug is connected to a 230 V power supply network.
Take the following measures to start the priming process (the process can take up to
4 minutes):
ü
The mains water storage tank has been filled with water.
1. Open a consumer installation (e.g. water connection in the garden).
2. Set the master switch to 1.
3. Set the operating mode selector switch to
rainwater mode
.
4. Press and hold down the reset key until the pump set is operating normally.
ð
The pressure gauge indicates 2.5 to 4 bar.
Should the priming process take longer, verify the following preconditions:
▪
The suction losses correspond to the system specifications.
▪
The suction line is tightly sealed.
▪
The suction line is sufficiently submerged in water.
