v
Position the pump at a safe distance (min. 2 m) from the water.
The pump must be installed in a location with low air humidity and suffi-
cient ventilation in the area of the ventilation slots. It must be at a distance
of at least 5 cm from the walls. Dirt (e. g. sand or soil) must not be sucked
in through the ventilation slots.
The plastic connection pieces on the intake and delivery sides may
only be tightened by hand.
Fixed installation of the pump [ Fig. A1 ]:
A mounting plate
(12)
e. g. wooden plate (not included) prevents the pres-
sure tank unit from slipping.
v
The Pressure Tank Unit can be screwed with all 4 feet
(11)
onto a solid
surface
(12)
(We recommend the use of inbus screws).
Install the pressure tank unit so that there is room to place a suitably sized
drainage tray under the drain screw
(9)
to allow the unit or system to be
drained.
If possible, install the pump higher than the surface of the water to be
pumped. If this is not possible, install a vacuum-resistant valve between
the pump and the suction hose.
For permanent indoor installations for domestic water supply, the Pressure
Tank Unit should not be connected to the domestic water pipework with
rigid pipes but with flexible tubing, to reduce noise and to avoid damage to
the pump caused by pressure blows.
If the system is being installed permanently, please fit suitable valves on
both the intake and delivery sides. This is important e. g. for maintenance
and cleaning work or if the system is being shut down.
To connect the hose to the suction side [ Fig. A2 ]:
Don’t use any hose quick connection system fittings on the suction side!
v
A vacuum-resistant suction hose must be used, e. g.
GARDENA
Suction Unit, Art. 1411
or
GARDENA Bore Hole Suction Hose
Art. 1729
.
A suction hose with backflow preventor must be used so that
the suction hose does not drain automatically when the pump
is switched off.
1. Screw the non-return valve
(2)
into the pump connection
(1)
with the
O-ring
ß
o
in the direction of the pump up to the stop
(a)
until the stop
(a)
touches the pump connection
(1)
.
2. Connect the vacuum-resistant suction hose
(3)
airtight to the pump
non-return valve
(2)
.
3. For suction heights exceeding 4 m: Also secure the suction hose
(3)
(e. g. by fastening it to a wooden post).
This relieves the pump of the weight of the suction hose.
To connect the hose to the pressure side [ Fig. A3 ]:
The pump connection
(4)
is equipped with a 33.3 mm (G 1") internal
thread.
Tip: If permanent pipes are installed, they must be laid at an
ascending angle in order to allow the water to flow back into the
pump on the pressure side.
Optimised use of the pump capacity is achieved by connecting
19 mm (3/4") hoses with e. g.
– GARDENA Pump Connection Set Art. 1752,
or by connecting 25 mm (1") hoses with
– GARDENA Quick Thread Coupling with male thread Art. 7115 /
Quick Coupling Hose Connector Art. 7103.
1. Screw the pump connection piece
(c)
into the connector on the delivery
side
(4)
.
2. Connect the pressure hose
(5)
to the pump connection piece
(c)
.
When using other connectors, then use sealing tape
(P)
on the external
thread of the fittings.
If more than one hose /accessory is connected simultaneously, we
recommend using the
– GARDENA 2- or 4-Channel Water Distributor Art. 8193 / 8194,
GARDENA Twin-Tap Connector Art. 940
which can be screwed directly onto the pump connection piece
(c)
.
3. OPERATION
DANGER! Risk of injury!
Injury when the product starts accidentally.
v
Disconnect the product from the mains before you connect,
adjust or transport the product.
To pump water [ Fig. O1 / O2 ]:
CAUTION! Dry-Running of the pump!
v
Fill the pump with water up to the overflow (approx. 2 to 3 l)
before each start-up.
1. Check the pressure in the storage tank (see 4. MAINTENANCE).
2. Unscrew the screw fitting
(6)
of the filler neck
(7)
by hand.
3. Fill the pump via the filler neck
(7)
to overflowing with
approx. 2 to 3 l of water.
4. Tighten the screw fitting
(6)
of the filler neck
(7)
by hand
(do not use pliers).
5. Open any shut-off valves in the delivery line (accessories,
water stop, etc.).
6. Drain remaining water in pressure hose
(5)
so that air can escape
during the suction process.
7. Connect the pump to the mains.
8. Lift and hold the delivery hose
(5)
at least 1 m vertically above the pump,
push the On / Off switch
(8)
and wait until the pump has primed.
v
If the pump does not deliver water after approx. 5 minutes,
switch off the pump (press On / Off switch
(8)
)
(see 6. TROUBLESHOOTING).
Once the maximum pressure is reached the pump will switch off automati-
cally. When the pressure falls below the minimum value due to water being
drawn off, the pump will switch on again automatically.
The specified maximum self-priming suction height of 7 m is reached
only if the pump is filled via the filler neck up to the overflow and if, while
doing so and during the self-priming, the delivery hose
(5)
is held up suf-
ficiently high to prevent any water escaping from the pump via the delivery
hose
(5)
.
4. MAINTENANCE
DANGER! Risk of injury!
Injury when the product starts accidentally.
v
Disconnect the product from the mains before you maintain
the product.
To flush the pump:
After pumping chlorinated water, the pump must be flushed.
1. Pump lukewarm water (max. 35 °C), possibly adding a mild cleaning
agent (e. g. detergent) until the pumped water runs clear.
2. Remove residuals according to the waste disposal laws applicable in
your area.
To check the pressure in the storage tank [ Fig. M1 ]:
Check the pressure in the reservoir tank regularly.
The pressure in the storage tank must be approx. 1.5 bar. An air pump /
tyre inflator with pressure indicator (manometer) is required to refill the air.
1. Unscrew the protective cover
(13)
.
2. Open all the tapping points.
The pressure side is depressurised.
3. Place the air pump / tyre inflator on the tank valve
(14)
and refill with
air until the pressure display on the air pump / tyre inflator shows
approx. 1.5 bar.
4. Screw the protective cover
(13)
close again.
5. STORAGE
To put into storage [ Fig. S1 ]:
The pump is not frost-proof!
The product must be stored away from children.
1. Disconnect the pump from the mains.
2. If applicable, close all the shut-off devices on the intake side.
3. Open all the tapping points.
The pressure side is depressurised.
