ASSEMBLY

Risk of injury!
Injury when the product starts accidentally.

• Disconnect the product from the mains before you assemble the product.

The hose can be connected via the pump connection and the connection nipple [19 mm (3/4") / 25 mm (1")] or via the GARDENA Connection System [13 mm (1/2") / 16 mm (5/8") / 19 mm (3/4")]. When using a 25 mm (1") hose, the pump has the maximum delivery capacity.
With a parallel connection of more than one hose or connected devices, the GARDENA 2- / 4-Way Valve (Art. 1210 / 1194) can be used, which is screwed straight onto the pump connection .

Connect hose via connection nipple [Fig. A1]:
25 mm (1")- and 19 mm (3/4") hoses can be connected via the connection nipple .

OPERATION

Risk of injury!
Injury when the product starts accidentally.

• Disconnect the product from the mains before you connect, adjust or transport the product.

To pump water

[Fig. O1]: The pump must always be submerged in the well or water reservoir with the rope provided. For the pump to be primed, the pump must be submerged at least 60 mm. So that the filter does not become dirty, the pump should be fixed at least 30 cm above the ground.

1. Attach the rope securely to the handle .
2. Submerge the pump in the well or water reservoir via the rope .
3. Secure the rope .
4. With deep wells or shafts (from approx. 5 m), route the connection cable along the rope with clips.
5. Connect the pump to the mains.
   The pump starts approx. 3 sec. after connecting the connection cable.

The pump is ready for operation.

Automatic mode with float switch

[Fig. O2]: So that the pump automatically switches off when there is no liquid to pump, the Float Switch must be able to freely move on the surface of the water.

To adjust the Cut-in and Cut-out Height

[Fig. O3]: The maximum cut-in height and minimum cut-out height (see "TECHNICAL DATA") can be adjusted by pushing the float switch wire into the float switch lock .

• The shorter the length of cable between the float switch and the float switch lock , the lower the cut-in height and the higher the cut-out height.

• Push the cable of the float switch into the opening in the float switch lock .

In order to ensure that the float switch is able to switch on and off, the cable length between the float switch and the float switch lock must be at least 10 cm.

Manual operation

[Fig. O4]: The pump remains permanently in operation because the float switch is bypassed. This deactivates the dry-running protection of the pump.

1. Push the float switch onto the float switch locking with the cable downwards.
2. Immerse the pump in a well or shaft using a rope attached to the pump.
3. Connect the pump to the mains.
   Attention! The pump begins operating immediately.

The minimum residual water depth (see "TECHNICAL DATA") is only achieved in manual mode because the float switch already switches off the pump before this when in automatic mode.

MAINTENANCE

Risk of injury!
Injury when the product starts accidentally.

• Disconnect the product from the mains before you maintain the product.

To clean the filter

[Fig. M1]: In order to ensure continuous trouble-free operation, the filter should be cleaned at regular intervals.

After pumping dirty water, the filter must be cleaned immediately.

1. Turn the filter 1/4 turn clockwise and remove it (bayonet lock).
2. Clean the filter under running water.
3. Re-install the filter in the opposite sequence.

The pump must not be operated without the filter.

To flush the unit

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.

STORAGE

To put into storage:
The pump is not frost-proof!
The product must be stored away from children.

1. Disconnect the pump from the mains.
2. Turn the pump upside down until no more water runs out.
3. Clean the pump (see "MAINTENANCE").
4. Store the pump in a dry, enclosed and frost-free place.
