11.3 Cleaning the dirty water pump
Cleaning of the dirty water pump becomes due when the rotor of the pump motor
(33)
is heavily soiled or
blocked. This can happen as a result of larger soiling, such as, e.g. stones. The LED indicator
(C2)
on the
controller
(15)
How to clean the dirty water pump (Fig. N)
1. Turn the motor housing
(33)
until the symbol showing "Lock open" points to the arrow on the top
pipe
(31)
.
2. Remove and clean the motor housing
(33)
.
3. Reassemble in the reverse order.
– Important: The motor housing
(33)
is only arrested when the "Lock closed" symbol points to the
arrow on the top pipe
(31)
(Figure N)
.
4. Press the PUMP button
(C4)
once.
– The LED
(C2)
changes from red to green. The dirty water pump
(14)
starts up. Otherwise, the dirty
water pump
(14)
will not start up because of a malfunction. In this context, please refer to Chapter
Remedy of faults
.
5. If necessary, clean the overflow on the top pipe
(31)
. To this effect, open the soiling pipe cover
(32)
.
11.4 Changin
g the UVC lamp in the UVC clarifying unit
Attention!
Dangerous ultra-violet radiation.
Possible consequences:
Severe injury to the eyes and the skin.
Protective measures:
Only switch the unit on with the housing fitted.
The controller
(15)
does not s
how when the UVC lamp is defective. Check the function of the UVC lamp
by looking into the control window
(18)
at regular intervals
(Figure O)
.
The operating life of the UVC lamp being limited, it has to be replaced once its useful life has elapsed
(plea
se also refer to Chapter
Checking the reading of the UVC clarifying unit operating counter
).
1. Turn the water housing
(35)
until the symbol showing "
Lock open" points to the arrow at the UVC top
pipe
(34) (Figure O)
.
2. Pull off the water housing
(35)
(Figure O)
.
3. Remove the cleaning rotor
(37)
from the quartz glass tube
(45)
(Figure P)
.
4. Loosen the screw
(40)
from the union nut
(39)
, then unscrew the union nut
(39)
(Figure Q)
.
5.
Pull off the quartz glass tube
(45)
including the O ring
(46)
by a rotary movement
(Figure R)
.
6.
Pull off the UVC lamp protection
(44)
(Figure R)
.
7.
Pull the UVC lamp
(43)
out of its position in the UVC top section
(34)
and replace
(Figure R)
.
8.
Reassemble the UVC clarifying unit in the reverse order.
– Important: The water housing
(35)
is only closed when the "Lock closed" symbol points to the arrow
on the UVC top section
(34)
(Figure O)
.
►
During assembly ensure that the stop
(41)
of the union nut
(39)
butts against the stop
(42)
on the UVC
top section
(34)
. Only then can the screw
(40)
be turned in
(Figure Q)
.
►
The O ring
(36)
on the water housing closure
(35)
is firmly clamped on. Only remove the O ring
(36)
if it needs replacing, e.g. has become brittle
(Figure O)
.
► Condensate forms in the quartz glass tube
(45)
. This condensate cannot be avoided, however, it does
not impair function and safety.
► The quartz glass tube
(45)
can become scratched or blind over time. In this case, sufficient cleaning
performance of the UVC lamp
(43)
is no longer guaranteed.
The quartz glass tube
(45)
must be
replaced.
