PRODUCT DESCRIPTION

Various different models of garden pumps are de-scribed in this documentation. Identify your model using the identification plate.

Product overview
see Fig. A-D

Function
The garden pump draws the water via the suction line and feeds it to the pump outlet via the filter. The garden pump is switched on and off with the START / STOP button.

Inox stainless steel
Units marked with the designation “INOX” are supplied in stainless steel. The structure and function are unaffected by this.

Designated use
The garden pump is intended for private use in house and garden. It must only be used in the framework of the deployment limitations in accordance with the technical data.

The garden pump is suitable for:

• Watering and irrigating
• Re-pumping and pumping out of vessels (e.g. swimming pools)
• Water extraction from streams, rainwater butts and cisterns.

The garden pump is is suited exclusively for the conveying of the following fluids:

• Clear water, rainwater
• water containing chlorine (e.g. swimming pools)

Any other use shall be regarded as misuse.

Possible misuse
The garden pump must not be used continuously.

They are not suitable for conveying:

• Drinking water
• Salt water
• Waste water
• Foodstuffs
• Aggressive media, chemicals
• Corrosive, flammable, explosive or fuming fluids
• Fluids that are hotter than 35 °C
• water containing sand and abrasive fluids.

SCOPE OF DELIVERY

The house water system is supplied with a pressure switch, a pressure gauge and a mains lead.

Thermal protection

The unit is fitted with a thermal protection switch which switches the motor off in the event of over-heating. The pump switches on again automatically after a cooling down period of approx. 15 -20 minutes.

SAFETY INSTRUCTIONS

CAUTION!
Risk of injury!
Use the machine and the extension ca-ble only in perfect working order. Damaged equipment may not be operated.
Do not disable safety and protective de-vices!

• Children, or people who are not familiar with the operating instructions, are not allowed to use the machine.
• Never lift, transport or suspend the unit using the connection cable.
• Unilateral modifications or conversions of the unit are prohibited.

Electrical safety

CAUTION!
Danger when touching voltage con-ducting parts!
Disconnect the plug from the mains if the extension cable is damaged or severed! We recommend connecting a RCD (residual current operated device) having a nominal residual current of < 30 mA.

• The pump may not be operated while people are in the pool or pond.
• The house mains voltage must agree with the details quoted in the technical data, do not use any other supply voltage.
• The unit must only be operated with an electrical installation in accordance with DIN/VDE 0100, Part 737, 738 and 702. Protection must be provided by a 10 A line protection switch and a RCCD (residual current opera-ted device) having a nominal residual current of 10/30 mA.
• Use only extension cables that are suitable for use outdoors – minimum cross-section 1.5 mm2. Cable drums should always be unrolled completely.
• Damaged or brittle extension cables must not be used.
  ➯ Check the condition of your extension cable each time you start to use the equipment.

ASSEMBLY

Setting up the equipment

1. Prepare a flat and solid location.
2. Erect the unit horizontally and safe from the risk of flooding.
   ➯ The unit must be protected from the rain and direct water jets.

Connecting the suction line

1. Select the length of the suction line (Fig. B – 17) to make sure that the house water system cannot run dry. The suction line must al-ways be at least 30 cm under the surface of the water.

2. Connect the suction line. Make sure that the connection is tight, but do not damage the thread.
   ➯ We recommend using flexible lines at the pump inlet (Fig. A -10). This ensures that pressure or tension on the house water system cannot be exerted.

3. If the water has a small amount of sand in it, a pre-filter must be fitted between the suction line and the pump inlet. Ask your expert dealer about this.

4. Always lay the suction line with an upward gradient.
   If the suction height is more than 4 m, you must use a suction hose having a diameter greater than 1″. We recommend the use of an AL-KO suction unit with suction hose, suction filter and flow-back stop. Ask your expert dealer.

Mounting the pressure line

1. Screw the connecting nipple (Fig. B -15) with the round seal ring (Fig. B -16) into the pump outlet (Fig. A -3).
2. Screw the elbow nipple (Fig. B -13) with seal ring (Fig. B -14) onto the connecting nipple (Fig. B -15) and turn the elbow nipple in the desired direction.
3. Fix a pressure line (Fig. B -12) to the elbow nipple (Fig. B -13).
4. Open all closing off devices (valves, spray nozzles, water cock) in the pressure line.

STARTUP

Filling the unit

CAUTION!
Dry running will destroy the pump! The pump must be filled with water up to the overflow before each use so that it can draw water immediately.

1. Open the filling screw (Fig. A -3) with the filter key.
2. Fill with water via the filling screw until the marl on the pump housing is reached.
3. Screw the filling screw back in position.

In order to reduce the suction time, fill the suction hose with water before screwing in position.

Switch the pump on

1. Open all closing off devices (valve, spray nozzle, water cock) in the pressure line.
2. Insert the mains plug on the connection cable into the plug socket.
3. Switch the garden pump on at the on / off switch.

CAUTION!
Do not allow the pump to run against a closed off pressure line.

Switch pump off

1. Switch the garden pump off at the on / off switch after use.
2. Close all the closing off devices in the pressure line.

CAUTION!
Danger of injury from hot water
In extended use against the closed pressure side (>10 min.), the water in the pump can be severely heated up and can be emitted in an uncontrolled manner! Isolate the unit from the mains and allow the pump and water to cool down. Start the unit again only after all the faults have been rectified!

The risk of injury from hot water can arise if:

• the installation is not correct
• the pressure side is closed off
• there is a lack of water in the suction line, or if
• the pressure switch is defective.

Procedure

1. Isolate the unit from the mains and allow the pump and water to cool down.
2. Check the unit, the installation and water le-vel.
3. Start the unit again only after all the faults have been rectified!

MAINTENANCE AND CARE

CAUTION!
The pump must be isolated from the mains before any maintenance and service work. Remove the mains plug from the plug socket.

Clean the filter

1. Drain screw filter chamber (Fig. A -10) un-screw the draining opening, drain the filter chamber and close the draining opening again.
2. Unscrew clear sight cover filter (Fig. A -9) using the filter key (Fig. C -18/D) .
3. Remove filter (Fig. C -20) from the filter housing and clean under flowing water.
4. Clean the filter housing and clear sight cover of the filter.
5. Before fitting the filter, check the filter seals (Fig. C -19) and the housing seal (Fig. C -23) and replace if necessary.
6. Fit the filter, screw the clear sight cover in place and tighten hand-tight with the filter key.

Cleaning the check valve

1. Removing and fitting the filter (see Section “Cleaning the Filter”).
2. Check valve (Fig. C -18) and clean under flowing water.
3. Replace seal (Fig. C -19) if necessary.
4. Fit check valve.

Unscrew float body

1. Pressure line (Fig. B -8) with elbow nipple (Fig. B -10) and connecting nipple (Fig. B -12) must be unscrewed.
2. Unscrew screw-in nipple (Fig. D -21) with seal (Fig. D -22) . Note the fitting position of the float body (Fig. D -23) . Pull out the float body and clean it.
3. Replace the float body – note fitting position (Fig. D).

Flushing the pump
After conveying swimming pool water containing chlorine or fluids that leave a residue the pump must be flushed out with clear water.

Remove blockages

1. Isolate the unit from the mains and secure against switching on again.
2. Remove the suction hose from pump inlet.
3. Connect the pressure hose to the water sup-ply.
4. Allow water to run through the pump housing until the blockage is removed.
5. Check that the pump is running freely by switching it on briefly.
6. Start the house water system again as described.

STORAGE

1. Drain the suction and pressure lines.
2. Unscrew the drain screws (Fig. A -10,10A) using the filter key and allow the water to flow out of the pump.
3. Screw the drain screws back in place and store the pump and accessories in a frost-free environment.

If there is a risk of frost, the system must be completely drained.

DISPOSAL
Do not dispose of worn-out machines or spent batteries (including recharge- able batteries) in domestic waste! The packaging, machine and accessories are made from recyclable materials and must be disposed of accordingly.
