2. Description of functions

Full pumping capacity
On take-off of the entire flow rate, the
water flows via
water inlet (6),
float tank (5),
precompression pump hot water (9)
(only in HD xxxx CH),
high-pressure pump (1),
to high-pressure outlet (10).
Part take-off
If only part of the water capacity fed by the
pump is required, the remaining volume
flows via the
flow control (4) back
to the suction side of the high-pressure
pump (1).
Detergent
Detergent is drawn in by the high-pressure
pump (1) via the manual detergent mete-
ring device (7)
Automatic pump start
If the system pressure drops during the
available time owing to the opening of a
consuming device, then the high-pressure
pressure switch (2) starts the pump.
Automatic switch-off
If the water flow in the flow control device
(4) rises as a result of little or no water take-
off, the pressure also rises at the low-pres-
sure pressure switch (3). If the pressure
exceeds a threshold value, the switch-off
procedure begins:
After one second the pumps stops and
the "available" time begins.
5.959-490 A 12578 (12/99)
C. System Function
If a take-off of water happens inside the
"available" time, the pump starts up
again.
When the system-available time has
expired, the system is set in operation
by switching off the Emergency-Stop
master switch and switching it on again,
or by pressing the remote unlock button
(option).
