The Electronic Manometric Switch
is equipped with an electronic
control unit with fixed programs.
The electronic control unit is acti-
vated by pulses from the mano-
metric switch and the flow recog-
nition of the dry-running safety
feature.
The manometric switch is set
at the factory to a switching
pressure of approx.2.2 bar.
This setting cannot be changed.
The dry-running safety mech-
anism protects the pump
against damage and controls
the time the pump continues to
run against the closed delivery
side.
The LEDs (light emitting diodes)
display the operating status
(➔ see “Electronic Control Dis-
play”).
Explanation of Terms
..
Priming cycle
The pump attempts to restore
normal operation in 4 minutes.
..
Automatic self-priming mode
(
➔➔
yellow Alarm LED flash-
es)
After a fault, the pump’s elec-
tronic control unit makes three
automatic self-priming attempts
at different time intervals (after
1 hour, after 5 hours and after
20 hours) to restore normal
operation.
The priming cycle (see above)
is used for each of these at-
tempts.
..
Re-plugging
(removing the mains plug
and then plugging it
back in the socket again)
Important! Remove the plug
from the socket! Check the
unit and pump for any faults
(see section “Finding Faults”).
Rectify any faults and restart
the pump by plugging the
mains plug into a socket sup-
plying 230 V AC.

..
RESET Button (ill. F1)
The RESET button is used
to reset and restart the pump
after a fault.
..
Red Power LED is lit (ill. F2)
The pump is connected to
the mains power.
The pump functions in the
normal operating mode.
..
Green LED is lit (ill. F3)
The pump is connected to the
mains and the pump is running.
Once the pump has reached
the max. pump pressure, the
pump switches off (the green
LED extinguishes) and the
pump functions in the normal
operating mode.
..
Green LED flashing slowly
(once a second) (ill. F4)
➔ The flow rate on the deliv-
ery side is too low (below
90 l/h).
The pump continues to run
and then switches off.It
turns on again as soon as
the switching pressure of
approx.2.2 bar has been
reached (e.g.in the case
of a leak).
➔ The pump must be switched
off just before you finish
draining water from the unit.
..
Green LED flashing quickly
(four times a second) (ill. F5)
➔ The flow rate on the inlet
side is too low (below
400 l/h).
The pump continues to
run for approx.40 seconds.
If normal operation is not
achieved during this time,
the pump switches off and
the control unit changes
to the “automatic self-
priming mode”.
Not
e:The pump can be
switched on again at any
time by pressing the
RESET button.
..
Yellow LED flashing slowly
(once a second) (ill. F6)
➔ The amount of water is
too low when restarting
the pump.
The pump runs through
the first “priming cycle”.
If the normal operating
mode is not achieved, the
pump switches off and
the control unit changes
to the “automatic self-
priming mode”.
Not
e:The pump can be
restarted at any time by
pressing the RESET button.
..
Yellow LED flashing quickly
(four times a second) (ill. F7)
➔ Alarm which indicates if the
amount of water is too low
when the pump is operating
in the normal mode.The
control unit changes to the
“automatic self-priming
mode”.
Not
e:The pump can be
restarted at any time by
pressing the RESET button.
..
Yellow LED is lit (ill. F8)
➔ The “automatic self-
priming mode” is no longer
active and the unit is no
longer supplying water
(e.g.no water in the con-
tainer or borse or the filter
is dirty).
Not
e:The pump can be
restarted at any time by
pressing the RESET button
or by “re-plugging”.

8. Function and Display of the Electronic Manometric Switch
Important! Don’t use any hose
connection system fittings on
the suction side!
Delivery Side
G
4. Screw the second pump fitting
3
into the outlet nozzle of the
delivery side
G
of Electronic
Manometric Switch, and tighten
up by hand.Take care that the
washer of the pump fitting fits
closely to the delivery side.
Note 1: The pump fitting is
equipped with a 33.3 mm (G1)
thread to which 13 mm (1/2”),
19 mm (3/4”) and 16 mm
(5/8”) hoses can be connect-
ed by using GARDENA hose
connection system fittings.
Note 2: Best results regarding
the delivery capacity of the
pump are achieved when con-
necting 19 mm (3/4”) hoses
in conjunction with GARDENA
“Profi” Maxi-Flow System fit-
tings (e.g.art.no.1752) or
when using 25 mm (1”) hoses
with fittings available from
your sanitary dealer.
When connecting simultane-
ously several hoses / watering
accessories, we recommend
application of our GARDENA
Twin-Tap Connector (art.no. 1210)
or Four Channel Water Distributor
(art.no.1194) which can be
screwed directly onto the pump
fitting on the delivery side
G
.
Using the pump for the
first time
1.Set the switch of the backflow
valve to Position 2.
2.Slightly open the release
points in the delivery pipe (e.g.
spray lance, tap) ➔ air must
be allowed to escape during
the suction process.
3.Plug the mains plug
D
for the
Electronic Manometric Switch
into an outlet socket supplying
230 V alternating current.
Caution! The pump immedi-
ately starts to run!
4.As soon as the pump begins
to pump, turn the switch to
Position 1 (normal operation)
➔ ensures fault-free operation
of the pump.
6. Starting Operation
A
..
Caution: Pursuant to
DIN VDE 0100-702 and
0100-738 use of the pump
nearby swimming pools and
garden ponds and other
similar places is only permis-
sible, if the pump is operated
with a residual-current de-
vice with a residual-current
rating
≤≤
30 mA. Please ask
your electrician for his ad-
vice.
..
The pump must be located
on solid, even ground, pro-
tected from flooding.Take
care that the pump cannot
fall into water.
..
Mains power cables should
not have a smaller cross-
section than a rubber
sheathed cable of the desig-
nation H07 RNF. Extension
cables must meet the re-
quirements of DIN VDE 0620.
..
In Austria,the electrical
connections must be made
according to ÖVE-EM 42,
T2 (2000)/1979 § 22 based
on § 2022.1. Pursuant to this
regulation it’s imperative to
operate pumps for swimming
pools and garden ponds
exclusively via an isolating
transformer.Please ask
your electrician.
..
In Switzerland mobile appli-
ances which are used out-
doors, must be connected
via a residual-current device.
..
When using the pump for
domestic water supply,
please adhere to the local
water and sewerage regula-
tions. In addition observe
the regulations of DIN 1988.
If necessary,contact your
sanitary expert.
..
Children under the age of 16
are not allowed to operate
the pump. Keep them away
from the connected unit.
..
Protect the pump from rain.
Don’t use the pump in wet
or moist area.
..
Before operating the pump,
first make a visual check, if
there is any damage of the
pump (esp. regarding power
cable and plug). A damaged
pump must not be used. In
case of damage, please have
the pump checked by our
GARDENA Service Centre or
by an authorised electrician.
..
Check line voltage. Data
indicated on the type plate
must match technical data
of the mains supply.
