Cleaning the filter :
Starting up the filter set :
5. Initial Operation
1. Place the filter container
2
above the surface of the pond in
a stable position alongside the garden pond but at least 2 m
away from it.
2. Decide on the length of the supply hose
E
and the drain
hose
G
and cut to size.
3. Connect the filter supply hose
E
to the pump
D
.
4. Set up the pump
D
in a stable position in the garden pond
so that the pump is completely covered with water.
5. Connect the supply hose
E
of the pump
D
to the water
intake
F
(max. 50 cm above the surface of the water) of the
UVC unit.
6. Connect the drain hose
G
to the water discharge connec-
tion
H
(at least 5 cm above the surface of the water) of the
UVC unit and route it into the pond.
7. Plug the mains plug of the pump into a 230 V AC socket.
Warning : The pump will start immediately !
8. Plug the mains plug of the UVC unit into a 230 V AC socket.
The UVC warning light
I
goes on.
Do not allow the pump to run without water :
Do not allow the pump to run without water because dry-running
leads to an undesirable build up of heat and will destroy the pump.
6. Maintenance
The GARDENA filter is largely maintenance-free. However, it must
be cleaned when necessary.
1. Unplug the pump and the UVC unit from the mains.
2. Remove the filter cover
1
and the O-seal
B
.
3. Remove the foam filter mat
A
and remove coarse dirt under
flowing water.
4. Remove the net containing the filter pellets
0
and place it in
a solution of cooking salt (20 g salt / litre) for approximately
24 hours.
5. Then rinse the net
0
with fresh lukewarm water.
6. Place the bio-surface filter
9
in clean water for approximately
24 hours.
Do not clean under running water because this will destroy
the micro-organisms.
7. Empty the filter container completely and clean under running
water.
8. Reassemble filter in reverse order.
9. Start the filter up again
(see
5. Putting into Operation
“Starting up the filter set ”
).
We recommend cleaning the filter pellets approximately every
6 months or replacing them to guarantee that the filter pellets
are still able to work properly.
Please contact GARDENA Service about replacing the filter
pellets.
