3 Stop cock drain water tanks
4 Supply to the high-pressure pump
5 Stop cock water tanks
6 Supply from water tank on the right
Operation with water supply via the water tanks
When the tap (5) is open, water flows from the float con-
tainer into the water tank on the right and from there via the
connection (1) back into the water tank on the left.
This way, the filling level is the same in both 250-litre tanks
and the float container itself; it is monitored by the filling
level detector in the float container.
When operated via the water tanks, the water supply to the
high-pressure pump (4) takes place via the inlets of the
float container (2) and the supply (6) of the corresponding
water tanks.
Operation with external water supply
When operated with external water supply, the tap (5) is
closed so that the pump is only supplied by the supply (2)
from the float container.
The feed of the liquid softener takes place in accordance
with the setting on the service switch. The setting is de-
scribed under "Service switch". The feed only takes place
in the programme switch position "ECO" and "Warm wa-
ter" at a set water temperature
≥
50°C.
The empty message takes place via the level switch and is
shown on the display.
The burner operation is also possible without liquid soften-
er. With hard water, however, malfunctions due to lime de-
posits must be expected.
NOTE
The dosing unit must not be switched off when using RM
110.
