The max. permissible temperature of the pumped medium is 35^

4. Safety

4.1 Specified conditions of use

This equipment must not be used to supply drinking water or for pumping foodstuff.

Explosive, inflammable, aggressive fluids or substances detrimental to health and salt water must not be pumped.

This equipment is not suitable for commercial or industrial use.

Alteration of the equipment or use of parts not approved by the equipment manufacturer is not permitted.

Any inexpert use the equipment is not as specified; it can cause unforeseen damage!

4.2 General safety instructions

Children, juveniles and persons not familiar with the instructions are not permitted to operate the pump.

When used in swimming pools and garden ponds and their range of protection, the regulations according to DIN VDE 0100-702, -738 are to be observed.

When used as domestic water supply any applicable local regulations pertaining to water supply and waste water disposal, plus DIN 1988 (where applicable) are to be observed.

The following residual risks do principally exist when operating pumps and pressure vessels and can not be fully eliminated - even by employing safety devices.

Hazard by ambient conditions!

Do not expose to rain. Do not operate in damp or wet environment.

Do not direct water jet directly against the equipment or other electrical parts! Risk of fatal electric shock!

Do not use the pump in hazardous locations or near inflammable liquids and gases!

Danger: Hot water!

If the shut-off pressure of the pressure switch cannot be reached due to poor pressure conditions or a defective pressure switch the water can heat up within the pump as a result of internal circulation.

Through this the pump and the connection lines can become damaged or leaky, allowing hot water to escape. Danger of scalding!

• Do not operate the pump against a closed pressure line for longer than 5 minutes.
• Unplug the pump and allow to cool. A specialist must check the system to make sure it is in perfect working order before it can be used again.

Danger! Risk of electric shock!

Always unplug before servicing.

Do not touch the plug with wet hands! To unplug always pull on the plug, not the power cable.

Do not buckle, squeeze, drag or drive over power cable and extension cables; protect from sharp edges.

Danger by pump failings!

Before each use check the equipment, especially the power cable, plug and electrical parts for possible damage. Risk of fatal electric shock!

A damaged pump must be workmanlike repaired before it can be used again.

Do not attempt to repair the equipment yourself! Only trained specialists are permitted to service or repair pumps or pressure vessels.

Caution!

To avoid water damage, e.g. flooded rooms, caused by pump malfunctions or defects:

provide for suitable safety measures such as the following:

• alarm or
  collection tank with monitoring.

The manufacturer is not liable for any damage caused by:

improper use of the pump;
- overloading of the pump through continuous operation;
- failure to operate and store the pump in a frost-free environment;
- unauthorised modification of the pump (repairs to electrical equipment may only be carried out by qualified electricians!);
- use of spare parts which have not been tested and approved by the manufacturer; or
- use of unsuitable installation materials (fittings, connection lines etc.).

Suitable installation materials:

• pressure-resistant (min. 10 bar)
  heat-resistant (min. 100^)

5. Prior to Operation

The equipment is easily assembled and connected.

If in doubt, contact your specialist supplier or qualified electrician.

5.1 Installation

• The equipment must be placed on a plane and level surface, suitable of bearing the weight of the equipment fully filled with water.
• To prevent vibrations, the equipment should not be fastened with screws but placed onto an elastic base.
• The installation location should be well vented and protected from atmospheric exposure.
• When operated at garden ponds and pools the equipment must be set up safe against flooding and protected from falling into the water. Any additional legal requirements are to be observed.

5.2 Suction line connection

Note:

Possibly further accessories may be required for connection (see "Available Accessories").

Caution!

The suction line needs to be installed in such manner that it does not exert mechanical force or distortion to the pump.

Caution!

When pumping contaminated fluids install a suction strainer to protect the pump from sand and dirt.

Caution!

A check valve is required to prevent water backflow when the pump is switched off.

• All screw fittings need to be sealed with thread sealing tape; leakage places cause the priming of air and reduce or prevent the priming of water.
• The suction line should have at least 1'' (25 mm) inner diameter; it must be non-buckling and vacuum-proof.
• Keep suction line as short as practical, since with increasing length the pump capacity is reduced.

• The suction line should raise towards the pump to prevent air locks.

• A sufficient water supply must be ensured, the foot valve at the end of the suction line must be submerged in water at all times.

5.3 Discharge hose connection

Note:

Possibly further accessories may be required for connection (see "Available Accessories").

Caution!

The discharge (or pressure) line needs to be installed in such manner that it does not exert mechanical force or distortion to the pump.

• All screw fittings should be sealed with thread sealing tape to prevent leakage.
• All parts of the pressure line must be resistant to internal pressure.
• All parts of the pressure line must be installed in a workmanlike manner.

Danger!

Improper installation and use of parts not resistant to internal pressure can cause the pressure line to break during operation. Risk of personal injury by liquid spurting from the line under high pressure!

5.4 Connection to a pipe system

A permanent installation (e.g. for indoor domestic water supply) is also possible.

• To reduce vibrations and noise, the equipment should be connected to the piping with elastic hose pipes.

5.5 Mains connection

• Danger! Risk of electric shock!

• Do not operate the equipment at environment and only under following conditions:

• Connect only to an earthed outlet that is properly installed, earthed and tested.

• Mains voltage and fuse protection must correspond to those stated in the "Technical Specifications".
• When operated at pools, garden ponds and similar locations, the equipment must be protected by a residual current operated device (RCD, 30 mA) (DIN VDE 0100 -702, -738 or equivalent applicable local regulations). We recommend the use of RCD's as a general precaution for personal protection.
• When operated outdoors the electrical connections must be

splash-proof; they must not be placed in water.

• Use only extension cables of sufficient lead cross section (see "Technical Specifications"). Unroll cable reels fully.

5.6 Filling the pump and priming

Caution!

After installation, loss of water or priming of air the pump needs to be filled with water. Starting the pump without water causes damage!

Note:

The suction line does not need to be filled, the pump is self-priming. However, depending on length and diameter of the suction line it may take some time until pressure has built up.

1. Remove the water filler plug, complete with gasket.
2. Slowly pour in clear water, until the pump is filled.
3. To reduce the time needed for priming you can also fill the suction line.
4. Replace the water filler plug, complete with gasket.
5. Open pressure line (open tap or spray nozzle) for any air to escape during priming.
6. Start equipment (see "Operation").
7. Close pressure line when only water runs out.

6. Operation

Pump and suction line must be connected and filled (see "Prior to Operation").

Caution!

Pump must not run dry. Ensure there is always sufficient pumping medium (water) available.

• If the motor does not start, no pressure is built up or similar effects are evident, switch the equipment OFF and try to remove the fault (see "Trouble Shooting").
  If the pump should be blocked by a foreign object or the motor overheat, the motor protection will switch the motor off.

6.1 Commissioning

Note:

The pressure switch

• starts the pump when the water pressure in the tank falls below the cut-in pressure by drawing off water;
• stops the pump when the cut-out pressure is reached.

Note:

In the tank is a factory-

pressurized rubber bag ("air charge"); this enables the drawing-off of small amounts of water without starting the pump.

1. Plug power cable in.
2. Open pressure line (open tap or spray nozzle).
3. Check to see the water comes out!

6.2 Pump characteristic curve

The pump characteristic curve shows which pump capacity is possible in dependence on the delivery head.
