The information in these instructions is denoted as under: Danger! Risk of personal injury or damage to the environ- ment. Risk of electric shock! Risk of personal injury by electric shock. Caution! Risk of material damage Note: Additional information. − Numbers in illustrations (1, 2, 3, ...) − indicate component parts; − are consecutively numbered; − refer to the corresponding num- bers in brackets (1), (2), (3) ... in the neighbouring text. − Instructions to be carried out in sequence are numbered. − Instructions which can be carried out in any sequence are preceded by a bullet (•). − Listing are preceded by a dash (–). This pump is intended for pumping clear water in domestic applications, such as − irrigation, − well, rain and service water pump-

ng, − d raining of pools, garden ponds and water tanks. The max. permissible temperature of the pumped medium is 35 °C.

4.1 Specified Conditions of

Use This pump must not be used to supply drinking water or for pumping foodstuff. Explosive, flammable, aggressive fluids or substances detrimental to health as well as salt water must not be pumped. This pump is not suitable for commercial or industrial use. Modification of the pump or use of parts not approved by the manufacturer is not permitted. Any use other than the use specified above may cause unforeseeable dan- ger!

4.2 General Safety Instruc-

tions Children, juveniles and persons not fam- ilar with the instructions are not permit- ted to operate the pump. When used in swimming pools and gar- den ponds and within their range of pro- tection, the regulations of DIN VDE 0100 -702, -738 or applicable local regulation must be observed. When used as domestic water supply any applicable local regulations pertain- ing to water supply and waste water dis- posal, plus DIN 1988 (where applicable) have to be observed. The following residual risks do principally exist when operating pumps and pres- sure vessels and can not be fully elimi- nated – even by employing safety devices.

Hazard generated by ambient conditions!

• Do not expose to rain. Do not oper- ate in damp or wet environment.

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

If the shut-off pressure of the pressure switch cannot be reached due to poor pressure conditions or a defective pres- sure switch the water can heat up within the pump as a result of internal circula- tion. Through this the pump and the connec- tion 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!

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

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

• The earthed outlet or the plug con- nection to an extension cable must be located in an area safe against flooding.

• Use only extension cables of suffi- cient lead cross section (see Table of Contents

2. Please Read First!

3. Range of Application and

ENGLISH "Technical Specifications"). Com- pletely unroll cable reels.

• Do not buckle, squeeze, drag or drive over power cable and exten- sion cables; protect from sharp edges.

• Place extension cable so that it can not get into the fluid to be pumped.

• Unplug: − prior to all servicing; − when persons are in the swim- ming pool or garden pond.

Danger by pump failures!

• If you notice transport damage while unpacking, notify your supplier immediately. Do not operate the pump!

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

• A damaged pump must be work- manlike repaired before it can be used again.

• Do not attempt to repair the pump 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 mal- functions 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 continous operation; − failure to operate and store the pump in a frost-free environment; − unauthorised modification of the pump (repairs to electrical equip- ment 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 materi- als (fittings, connection lines etc.). Suitable installation materials: − pressure-resistant (min. 10 bar) − heat-resistant (min. 100°C). The pump is easily assembled and con- nected. If in doubt, contact your specialist sup- plier or a qualified electrician.

− The pump must be placed on a plane and level surface, suitable of bearing the weight of the pump fully filled with water. − To avoid vibrations the pump should be placed on an elastic base. − The installation location should be well vented and protected from atmospheric exposure. − When operated at garden ponds and pools the pump must be set up safe against flooding and safe- garded against falling into the water. Any additional legal requirements are to be observed.

5.2 Connecting the Suction

Note: Possibly further accessories may be required for connection (see "Availa- ble Accessories").

Caution! The suction line needs to be installed in such manner that it does not exert mechanical force or distor- tion to the pump.

Caution! When pumping contaminated fluids install a suction strainer to pro- tect the pump from sand and dirt.

Note: A check valve is recommended to prevent water backflow when the pump is turned off. − All screw fittings must be sealed with thread sealing tape; leaks cause the priming of air, which reduces or completely prevents the priming of water. − The suction line should have an inner diameter of 1" (25 mm) mini- mum and must be kink and vacuum resistent. − Keep suction line as short as practi- cal, as with increasing length the pump capacity is reduced. − The suction line should ascend 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.

Note: Possibly further accessories may be required for connection (see "Availa- ble Accessories").

Caution! The discharge (or pressure) line needs to be installed in such manner that it does not exert mechan- ical 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 pres- sure can cause the pressure line to break during operation. Risk of per- sonal injury by liquid spurting from the line under high pressure!

5.4 Connection to a Pipe

System A stationary installation (e.g. in an indoor domestic water system) is also possible. − To reduce vibrations and noises the pump should be connected to the pipe system with flexible tubing.

5.5 Connection to AC Power

Danger! Risk of electric shock! Do not operate the pump in wet environment and only under the fol- lowing conditions: − Connect only to an earthed outlet that is properly installed, earthed and tested. − Mains voltage and fuse protection must correspond with the requirement stated in the "Tech- nical Specications". − When operated at pools, garden ponds and similar locations, the pump 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 per- sonal protection. − When operating the pump out- doors the electrical connections must be splash-proof; the con- nections must not be placed into water. − Use only extension cables of suf- ficient lead cross section (see "Technical Specifications"). Com- pletely unroll cable reels.

5.6 Filling the pump and

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. How- ever, depending on length and diameter of the suction line it may take some time until pressure has built up.

2. Slowly pour in clear water, until the

3. To reduce the time needed for prim-

ing you can also fill the suction line.

5. Open pressure line (open tap or

spray nozzle) for any air to escape during priming.

6. Start pump (see "Operation").

7. Turn pump OFF when water runs

out steadily. Pump and suction line must be con- nected and filled (see "Prior to Opera- tion").

Caution! The pump must not run dry. Ensure there is always sufficient pumping medium (water) available.

• If the motor does not start, no pres- sure is built up or similar effects are evident, switch the pump OFF – and try to resolve the fault (see "Trouble Shooting"). Pump characteristic curve The pump characteristic curve shows which pump capacity is possible in dependance on the delivery head. (Pump characteristic curve for 0.5 m suction head and 1" suction hose.) (Pump characteristic curve for 0.5 m suction head and 1" suction hose.)

Note: The pressure switch − starts the pump when, by drawing water, the water pressure in the tank falls below the cut-in pressure; − stops the pump when the cut-out pressure is reached.

Note: In the tank is a rubber bag, factory- charged with air ("precharge pressure"); this permits the drawing of small amounts of water without the pump starting up.

1. Plug power cable in.

2. Open pressure line (open tap or

• Replace Duocone seal. − Pump blocked or out of order.

• see above. Pressure too low: − Suction line leaky or too much suc- tion head.

• see above. − Pump blocked or out of order.

• see above. − Pressure switch incorrectly adjusted.

• Check cut-in pressure and cut- out pressure, adjust if necessary.

7. Care and Maintenance

8. Trouble Shooting14

ENGLISH − Pump starts even when drawing only a small amount of water (approx. 0.5 l).

• Too little precharge pressure in the tank; increase. − Water dripping from air charging valve.

• Rubber bag in tank leaky; replace.

8.2 Adjusting the Pressure

Switch If – in time – the factory-set cut-in pres- sure or cut-out pressure has changed considerably, the original setting can be restored (see "Technical Specifica- tions").

Danger! Risk of electric shock by the terminals inside the pressure switch. Only qualified personnel is allowed to open and adjust the pressure switch.

1. Remove the pressure switch cover.

2. Open pressure line (open tap or

spray nozzle) and let run water. When the pump starts, read the cut- in pressure on the pressure gauge.

3. Close the pressure line again.

Read the cut-out pressure on the pressure gauge when the pump stops.

Caution! The factory-set cut-out pres- sure must not be exceeded.

4. To change the cut-out pressure, turn

nut (12) as follows: − turn clockwise to increase the cut-out pressure; − turn counter-clockwise to reduce the cut-out pressure.

5. To change the cut-in pressure, turn

nut (13) as follows: − turn clockwise to increase the cut-in pressure; − turn counter-clockwise to reduce the cut-in pressure.

6. If necessary, repeat steps 2.

through 5. until the desired values are set.

7. Replace the pressure switch cover.

8.3 Increasing the Precharge

Pressure When – in time – the pumps starts after only small amounts of water are drawn (approx. 0.5 l), the precharge pressure in the tank must be restored to the origi- nal level.

Note: The precharge pressure can not be read on the pump's pressure gauge.

2. Open pressure line (open tap or

spray nozzle) and drain water com- pletely.

3. Unscrew the plastic cover on the

front side of the tank; the charging valve is located behind itl.

4. Connect air pump or compressor

hose with a "car tyre" type connector and pressure gauge to the charging valve.

5. Inflate to the intended precharge

pressure (see "Technical Specifica- tions").

6. Plug pump in again and check func-
