• Read these instructions before use. Pay special attention to the safety instructions.

• Disregard of the operating instruc- tions invalidates the manufacturer's warranty; the manufacturer is not liable for any damages resulting from such disregard.

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

• Dispose of the packing in an envi- ronmentally friendly manner. Take to a proper collecting point.

• Keep these instructions for refer- ence on any issues you may be uncertain about.

• If you lend or sell this machine be sure to have the instructions go with it. This equipment is intended for pumping clear water in domestic applications, such as − irrigation, − well, rain and service water pump- ing, − draining 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 equipment must not be used to sup- ply drinking water or for pumping food- stuff. Explosive, inflammable, aggressive flu- ids or substances detrimental to health and salt water must not be pumped. This equipment is not suitable for com- mercial 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 dam- age!

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 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 pertain- ing to water supply and waste water dis- posal, plus DIN 1988 (where applicable) are 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 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 loca- tions 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! 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 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.).

2. Please Read First!

3. Range of Application and

ENGLISH Suitable installation materials: − pressure-resistant (min. 10 bar) − heat-resistant (min. 100°C). The equipment is easily assembled and connected. If in doubt, contact your specialist sup- plier or qualified electrician.

• 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 equip- ment 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 pro- tected 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 "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.

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 practi- cal, 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.

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 sys-

tem 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 in wet environment and only under the 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 Specications".

• 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 per- sonal protection.

• When operated outdoors the elec- trical connections must be splash-proof; they must not be placed in water.

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

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 equipment (see "Operation").

7. Close pressure line when only water

runs out. 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 pres- sure 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.

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.

5. Prior to Operation

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

3. Check to see the water comes out!

6.2 Pump characteristic

curve The pump characteristic curve shows which pump capacity is possible in dependance on the delivery head. Pump characteristic curve at 0.5 m suc- tion head and 1" suction hose – for model:

Danger! Prior to all servicing: − Unplug. − Ensure that pressure is relieved from equipment and connected accessories. Repair and maintenance work other than described here must only be car- ried out by qualified specialists.

7.1 Periodic maintenance

• Check equipment and accessories, especially electrical parts and parts under pressure for possible dam- age; have repaired, if necessary.

• Check suction and pressure lines for leakages.

• If the pump capacity lessens clean suction strainer and filter cartridge (if installed), replace if necessary.

• Check air charge of tank, increase if necessary (see "Increasing the air charge").

7.2 Danger of freezing

Caution! Frost damages the pump and accessories, as both always contain water!

• When there is danger of freezing, dismount equipment and accesso- ries and store at a freeze-proof loca- tion (see below).

7.3 Equipment dismounting

2. Open pressure line (open tap or

spray nozzle) and drain water com- pletely.

3. Drain pump and tank completely. To

do so, − remove the drain plug from the pump (except HWW 3300/20 K), − loosen the union nut of the flexi- ble metal hose at the tank.

4. Disconnect suction and pressure

lines from the equipment.

5. Store equipment in a frost-free

space (at least 5 °C).

Danger! Prior to all servicing: − Unplug. − Ensure that pressure is relieved from equipment and connected accessories.

• Mains voltage too low. − Use only extension cables with sufficient lead cross section (see "Technical Specifications").

• Motor overheated, motor protection relay tripped. − After cooling off the pump will switch ON again. − Ensure sufficient ventilation, keep vent slots clear. − Observe max. temperature of the pumped medium.

• Motor hums but does not start. − With the motor switched OFF, put screwdriver or similar through the fan cover's vent slots and turn the fan.

• Pump blocked or out of order. − Disassemble pump and clean. − Clean diffusor, replace if neces- sary. − Clean impeller, replace if neces- sary. Pump does not prime correctly or runs very noisily:

• Lack of water. − Ensure there is a sufficient water supply.

• Suction line leaky. − Seal suction line, tighten screw fittings.

• Suction head too high. − Observe max. suction head. − Install check valve, fill suction line with water.

• Suction strainer (accessory) blocked. − Clean, replace if necessary.

• Check valve (accessory) blocked. − Clean, replace if necessary.

• Water leaks between motor and pump, Duocone seal worn. − Replace Duocone seal.

• Pump blocked or out of order. − see above. Pressure too low or pump running continuously:

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

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

• Pressure switch misadjusted. − Check cut-in and cut-out pres- sure, readjust if necessary.

• Pump starts after only a minimal amount of water (approx. 0.5 l) has been drawn off. − Air charge in tank too low; increase.

• Water drips form air charging valve. − Rubb er bag in tank leaky; replace.

8.2 Pressure switch adjust-

ment If – during time – the factory-set cut-in and cut-out pressure changes consider- ably, it can be readjusted to the original setting (see "Technical Specifications").

Danger! Risk of electric shock when touching the terminal inside the pres- sure switch. Only qualified service technicians are permittted to open and adjust the pressure switch.

1. Remove the pressure switch cover.

2. Open pressure line (open tap or

spray nozzle) and drain water com- pletely. When the pumps starts, note cut-in pressure indicated by the pressure gauge.

3. Close pressure line.

When the pumps stops, note cut-out pressure indicated by the pressure gauge.

7. Care and Maintenance

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

4. To change the cut-out pressure, turn

nut (12) − clockwise to increase the cut-out pressure; − counter-clockwise to decrease the cut-out pressure.

5. To change the cut-in pressure, turn

nut (13) − clockwise to increase the cut-in pressure; − counter-clockwise to decrease the cut-in pressure.

6. If necessary, repeat steps 2. to 5.

until the desired values are set.

7. Put the pressure switch cover back

8.3 Increasing the air charge

If – during time – the pump starts after a minimal amount of water (approx. 0.5 l) is drawn off, the tank's air charge must be increased.

Note: The air charge pressure can not be taken from the pressure gauge.

2. Open pressure line (open tap or

spray nozzle) and drain water com- pletely.
