1.3.3 Additional personal safety warnings

DANGER!
Risk of suffocation!
Small parts can be easily swallowed.
→ Keep toddlers away when you assemble the product.

DANGER!
Risk of injury from hot water!
Pumped water is under pressure and when it hits the body or eyes directly can cause injury.
If the pump is operated for prolonged periods of time (> 5 min.) with the delivery side closed, the water in the pump may heat up so that there is a risk of scalding yourself with hot water.
→ Let the pump operate for max. 5 minutes against the closed pressure side or with missing water supply.
If the water supply on the intake side of the pump fails, the water in the pump can heat up so that if water emerges, injuries could be caused by the hot water.
→ Disconnect the pump from the mains and let the water cool.
→ Do not open any caps and screw connections when the water is hot.
→ Before restarting, secure the water supply on the suction side and fill the pump completely with water.
If hoses or pipes are exposed to the sun, they can become very hot.
Do not use the product with loose hair.
When connecting the pump to the water supply system, the country-specific sanitary regulations must be observed to prevent water not of drinking water quality being drawn back in.
→ Consult a specialist for sanitary installations.
In order to avoid dry-running of the pump, take care that the end of the suction hose is always submerged into the liquid.
→ Before each operation, fill the pump with water up to the overflow (min. 1.1 l)!
→ When filling the pump with water, make sure that no hoses or consumers are connected to the pump and that the pump is generally in a horizontal position.
→ Make sure that the hoses are laid without kinks.
Sand and other abrasive substances cause increased wear and reduce the pump’s output.
→Use a pump pre-filter for pumping sandy liquids.
Pumping dirty water, e. g. stones, pine needles etc., can cause damage to the pump.
→ Do not pump dirty water.
The minimum flow rate is 90 l/h (1.5 l/min). Connection devices with a lower flow rate must not be operated.

ASSEMBLY

DANGER!
Risk of injury!
Risk of injury due to accidental starting.
→ Unplug the plug of the mains cable from the mains socket.

2.1 Installation site:

• When installing below the water level, a shut-off device must be installed to prevent unwanted water loss.
• The installation site must be horizontal, solid and dry and allow the pump to stand securely.
• It must be at a distance of at least 2 m from the water.
• The pump must be installed in a flood-proof location with sufficient ventilation in the area of the ventilation slots.
• The distance to the walls must be at least 5 cm.
• Dirt (e. g. sand or soil) must not be sucked in through the ventilation slots.

2.2 To connect the hose to the suction side [ Fig. A6 ]:

The connector on the suction side (1) is equipped with a 33.3 mm (G 1″) external thread.
The connection piece on the suction side may only be tightened by hand [ Fig. A2 ].
In order to reduce the suction time, it is advisable to use a suction hose with backflow preventer avoiding automatic draining of the suction hose when the pump has been switched off [ Fig. A3 ].
Sucking in air in the suction system can lead to functional failure and increased noise generation.
→ Connect the suction system carefully.
→ Check the gasket regularly and replace it if necessary.
Don’t use any hose quick connection system fittings on the suction side.

A vacuum-resistant suction hose must be used on the suction side:

• e. g. the GARDENA Suction Unit Art. 1411 / 1412 / 1418
• or the GARDENA Bore Hole Suction Hose Art. 1729.
• Connect suction hoses (2) without threaded connection via a suction hose connection piece (e. g. Art. 1723 / 1724) to the connection of the suction side and screw it airtight.

2.2.1 There are 2 types of connection systems:
Intended for flat gasket:
No thread sealing tape is required.
→ Make sure that the flat gasket G is inserted in the suction hose connection piece and is undamaged.
Intended for thread sealing tape (Teflon):
No flat gasket is required.
An unsuitable sealing system can lead to leaks.
→ Use the sealing system intended for this purpose.

1.  Make sure that the flat gasket G is inserted in the suction hose connection piece.
2. Screw the vacuum-resistant suction hose (2) airtight on the connector on the suction side (1) . The connection piece must be placed straight on [ Fig. A1 ].
3. Lay the suction hose (2) straight and free of twists.
4. For suction heights exceeding 3 m: Fix the suction hose (2) additionally. (e. g. by fastening it to a wooden post).
   Therefore, the pump is relieved of the weight of the suction hose.

2.3 To connect the hose to the pressure side [ Fig. A7 ]:
The connector on the pressure side(3) is equipped with a 33.3 mm (G 1″) external thread.
The connection pieces on the pressure side may only be tightened by hand.
Optimised use of the pump capacity is achieved by connecting 19 mm (3/4″) hoses with:

• e. g. the GARDENA Pump Connection Set Art. 1752
• or by connecting 25 mm (1″) hoses with the GARDENA Quick

Thread Coupling with female thread Art. 7109 / Quick Coupling Hose Connector Art. 7103.
Hold or fix the pressure hose vertically to avoid kinking of the pressure hose at the vertical pump outlet.
Lay the hose flat on the ground; avoid u-shaped elevations of the hose and coiling it. In order to allow the air to escape optimally, lay out the pressure hose completely and give it a rising course as seen from the pump.
→ Connect the pressure hose (4) with the connector on the pressure side (3) .
2.3.1 To connect the pressure hose via the GARDENA quick connection system:
19 mm (3/4″) / 16 mm (5/8″) and 13 mm (1/2″) hoses can be connected via the GARDENA Connection System.

Art. 18216
19 mm (3/4″)| GARDENA Pump Connection Set| Art. 1752

2.3.2 Only for Art. 9056: Parallel connection of pressure hoses:
When connecting more than one pressure hose in parallel, we recommend the use of:

• e. g. the GARDENA 2- or 4-Channel Water Distributor Art. 8193 / 8194
• or the GARDENA Twin-Tap Connector Art. 940.

These can be screwed directly onto the connector of the pressure side (3) .

OPERATION

DANGER!
Risk of injury!
Risk of injury due to accidental starting.
→ Unplug the plug of the mains cable from the mains socket.

3.1 To start / To stop the pump [ Fig. O1 / O2 ]:

CAUTION!
Dry-Running of the pump!
Make sure that the pump is filled with water up to the overflow (min. 1.1 l) before each starting procedure.

3.1.1 To start the pump:

1. Connect the suction hose (In).

2. Disconnect the pressure hose (Out).

3. Unscrew the screw connection (5) on the filling opening (6) by hand.

4. Slowly fill in at least 1.1 l of water via the filler opening (6) until a stable water level is reached at the level of the suction side connection [ Fig. A4 ].

5. If a non-return valve is used: Fill the suction hose with water.
   This speeds up the suction process.

6. Empty the residual water in the pressure hose (4) before connecting.
   This allows the air to escape during the suction process.

7. After filling the pump: Connect the pressure hose (Out) to the pump.

8. Tighten the screw connection (5) on the filling opening (6) by hand (do not use pliers).

9. Open any shut-off valves in the pressure line (connection devices, water stop, etc.). All consumers must be opened to the max. possible position.

10. Insert the plug of the mains cable into a mains socket.

11. For high suction heights: Lift and hold the pressure hose (4) at least 1.8 m vertically above the pump during the suction process.

12. Push the On / Off switch (7) to the position On. The pump starts (the On/Off switch lights) and pumps the water after the suction process.
    The suction process can take up to 5 minutes.

If the pump does not pump water after 5 minutes:

1. Push the On / Off switch (7) to the position Off. The pump stops.
2. Let the pump cool down.
3. Search in the 6.2 Troubleshooting table for possible causes.
4. Start the pump again (see 3.1.1 To start the pump).

3.1.2 To stop the pump:
→ Push the On/Off switch (7) to the position Off.
The pump stops.
3.2 Hints to pump:
3.2.1 General tip on suction:
The specified maximum self-priming height is only reached when the pump is filled to the overflow via the filling opening and the pressure hose (4) is held upwards during the priming process so that no water can escape from the pump via the pressure hose (4) . Fill the pump before hoses, fixed piping etc. are connected to the pump on the pressure side.
This ensures that the pump can be completely filled with water (1.1 l) (air can escape).
The pump is to be filled with 1.1 l of water.

3.2.2 Silent operation:
The pump is silent. This advantage can only be maintained with the correct installation:
→ Choose a low-vibration base (e. g. do not place on metal sheets or plastic tanks).

3.2.3 Assembly of the prefilter
If a prefilter is too long, it can be assembled in another position (e. g. horizontally) instead of in the vertical position still below.

MAINTENANCE

DANGER!
Risk of injury!
Risk of injury due to accidental starting.
→ Unplug the plug of the mains cable from the mains socket.

4.1 To clean the Pump:

DANGER!
Risk of injury!
