Specified Use

This device is used for conveying clean water in the house and garden area, for sprinkling and watering, as a well pump, rain pump and domestic water pump and for pumping out swimming pools, garden ponds and water tanks. The pump is not intended for:

• continuous operation
• industrial or commercial use

The pump is not suitable for the transportation of:

• drinking water
• food
• saltwater
• explosive, flammable, aggressive, or hazardous materials (e.g. chemicals)
• liquids over 35°C
• water containing sand and liquids with an abrasive effect

The pump is not suitable for increasing pressure: if the pump is connected to a line that is already pressurized then a suitable pressure regulator should be installed upstream of this. The maximal pressure of the system must not exceed the stated maximum pressure of the pump under any circumstances. It should also be borne in mind that the inlet pressure is added to the cut-off pressure of the pump! This device is not designed for the use of persons (including children) with limited physical, sensory or mental aptitude or lack of experience and/or knowledge. Unauthorized modifications to the device and the use of parts that are not tested and approved by the manufacturer are prohibited. All improper use of the device is regarded as non-specified use; this can result in unpredictable damage! The user bears sole responsibility for any damage caused by inappropriate use. Generally accepted accident prevention regulations and the enclosed safety information must be observed.

General Safety Instruction

Pay attention to all parts of the text that are marked with this symbol for your own protection and for the protection of your device!

WARNING  – Reading the operating instructions will reduce the risk of injury.

WARNING  Read all safety warnings and instructions. Failure to follow all safety warnings and instructions may result in electric shock, fire and/or serious injury. Keep all safety instructions and information for future reference. Pass on your pump only together with these documents. Information in these operating instructions is designated as shown below:

• Danger!  Risk of personal injury or environmental damage.
• Risk of electric shock!  Risk of personal injury from electric shock.
• Caution!  Risk of material damage.

Special Safety Instructions
Children, adolescents and persons who are not familiar with the operating instructions must not use the device. Children should be supervised to ensure that they do not play with the device. The provisions of DIN VDE 0100-702 and -738 must be observed when the pump is being used in swimming pools and garden ponds and in the protected areas around them. The device must be supplied with a rated residual current of max. 30 mA through a residual-current device (RCD). The device must not be used if there are persons in the water. The statutory water and waste water specifications and the provisions of DIN 1988 must be observed when used for the domestic water supply. The following residual risks essentially remain when operating pumps and pressure vessels (equipment-specific) – they cannot be fully eliminated even if safety measures have been introduced.

Danger from the
environment!

• Do not expose the device to rain. Do not operate the device in a damp or wet environment.
• Do not use the pump in potentially explosive locations or near flammable liquids or gases!

Danger from hot water!

Danger! Install a check valve at the suction connection (8) to prevent water from flowing back into the suction line. This can reduce the following danger: Hot water can cause damage and leaks on the device and the connection lines, allowing hot water to escape. Danger of scalding! Devices with the designation HWW…: 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 device as a result of internal circulation. Devices with the designation P…: do not operate the device against a closed discharge line for longer than 5 minutes. Water that  circulates inside the device is heated up. In the event of a fault, unplug the device from the power supply system and allow it to cool. A specialist must check the system to make sure it is in perfect working order before it can be used again.

Risk of electric shock!
Never direct the water jet directly at the device or other electrical components! Risk of fatal electric shock! Always disconnect the device from the power supply system prior to installation and maintenance tasks. Do not touch the plug with wet hands! Always pull on the plug and not the power cable to disconnect it. Do not buckle, squeeze, drag or drive over the power cable or extension cables; protect them from sharp edges, oil and heat.

Danger due to deficiencies
or faults on the device! Check the device for possible damage – especially the mains cable, mains plug and electrical components before each use. Risk of fatal electric shock! A damaged device must only be reused after it has been correctly repaired. Do not attempt to repair the device yourself! Only specialists are permitted to repair pumps and pressure vessels (equipment- specific).

Caution!  To prevent water damage, such as flooded rooms, caused by deficiencies or faults on the device:

• Provide appropriate safety measures, e.g. alarm device 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.
• Use of unsuitable installation materials (fittings, connection lines etc.).

Suitable installation materials:

• pressure-resistant (min. 10 bar)
• heat-resistant (min. 100°C). When using universal swivel couplings (bayonet couplings), only use versions with an additional securing ring to ensure safe sealing.

Commissioning

Installation
The unit must be set up horizontally at a dry (humidity max. 80 %), well- ventilated site that is free of atmospheric influences. Ensure that the unit is positioned on a secure, level and firm base when full of water. The air vents must not be covered or suck in dirt. There should be a clearance of at least 5 cm from walls and other objects. Protecting against frost – see section 8.2. The device should not be bolted on but rather positioned on a resilient base to avoid vibrations. The device must be installed in a flood- proof location and secured against falling in for operation in garden ponds and swimming pools. Additional statutory requirements must be taken into consideration.

Connecting the suction line

• Caution!  The suction line must be installed in such a way that no mechanical or twisting forces are exerted on the pump.
• Caution!  Use an intake filter to protect the pump against sand and contamination.
• Caution!  The check valve is absolutely

essential to prevent the water from draining when the pump is switched off. We recommend the installation of check valves at the intake opening of the suction hose and at the suction connection (8) of the pump. A check valve may already be integrated depending on the model (see section 13. Technical Specifications). Seal all fittings with thread seal tape (approx. 10-15 windings in the thread direction). Leaks result in the intake of air and reduce or prevent the intake of water. The suction line should have an internal diameter of at least 1″ (25 mm); it must be kink- and vacuum- resistant. The suction line should be as short as possible because the longer the line length, the lower the conveying capacity.

The suction line should rise uniformly towards the pump to prevent air pockets. An adequate supply of water must be guaranteed and the end of the suction line should always be under water. Ensure that the suction line is not on the ground so that no sand or dirt is sucked in. It is possible, for example, to use a floating intake as an accessory.

Connecting the discharge line
In order to reduce friction losses, the discharge line should have an interior diameter of at least 1” (25 mm). If using smaller diameters, such as 1/2” then application problems may arise due to inadequate ventilation. Caution! The discharge line must be installed in such a way that no mechanical or twisting forces are exerted on the pump. Seal all fittings with thread seal tape to prevent water leakage (approx. 10-15 windings in the thread direction). All discharge line components must be pressure-resistant and installed correctly. Danger! The discharge line can burst during operation if non-pressure- resistant components are installed or they are assembled incorrectly. Injuries are possible if highly pressurised fluids are ejected!

Connection to a pipe network
The device should be connected to the pipe network with flexible hose lines to reduce vibration and noises. In the case of fixed pipes, it is recommended that these are laid only rising in the first 2 metres to ensure optimal ventilation.

Power supply connection
Risk of electric shock! Never operate the device in a wet environment and only under the following conditions:

• Connect it only to an earthed outlet that is properly installed, earthed and tested.
• The mains voltage, mains frequency and fuse protection must correspond to those stated in the “Technical Specifications”.
• The device must be supplied with a rated residual current of max. 30 mA through a residual-current device (RCD).
• The electrical connections must not be under water and must be located in a flood-proof area. The connections must be splash-proof for outdoor use.
• Extension cables must have sufficient conductor cross sections. Cable reels must be fully unrolled.
• National installation specifications must be observed.

Setting the pilot pressure (only HWW…)
Set the pilot pressure before the initial operation. See section 9.4.

Filling the pump and suction
Caution! The pump must be filled with water with every new connection and in the case of water loss or air intake. Operating the pump without filling it with water will destroy it! In order to ensure trouble-free operation, we recommend sufficient removal of water so that the system is fully ventilated before initial use.

• Unscrew the water filling screw (9) with the gasket.
• Slowly pour in clean water until the pump is filled.
• Screw in the water-filling screw (9) with the gasket again.
• Open the discharge line (open the water tap or spray nozzle) so that air can escape during suction.
• Switch on the device (see section 7.).
• The device is ready for operation when water emerges evenly.

Note:  the suction line does not need to be filled because the pump is self-priming. However, it may take some time until pressure is built up depending on the length and diameter of the line. To shorten the suction time: install a check valve at the intake opening of the suction hose and fill the suction line too.

Operation

• Caution!  The pump and suction line must be connected and filled (see section 6.).
• Caution!  The pump must not be allowed to run dry. There must always be sufficient conveying medium (water) available.
  A protective circuit shuts down the motor if the pump is blocked by foreign bodies or the motor is overheated.

Using the device
Garden pump (Device designation P…)

Principle of operation: the device runs when it is switched on.

Danger!  Run the pump for a maximum of 5 minutes if the discharge line is closed because otherwise overheating of the water in the pump can cause damage.

1.  Insert the mains plug.
2. Fill the pump if necessary – see section 6.7 Switch on the device:
3. Turn on the device at the switch (1).
4. Open the discharge line (open the water tap or spray nozzle).
5. Check that water emerges!
6. Switch off the device when work is complete. Turn off the device at the switch (1).

Domestic waterworks (Device designation HWW…)
Principle of operation: the device switches on when the removal of water causes the water pressure to fall below the switch-on pressure; it switches off again when switch-off pressure is reached. The pressure vessel contains rubber bellows that are under air pressure (“pilot pressure”) when delivered; this permits the removal of small volumes of water without the pump starting up.

1.  Insert the mains plug.
2. Fill the pump if necessary – see section 6.7
3. Switch on the device: Turn on the device at the switch (1).
4. Open the discharge line (open the water tap or spray nozzle).
5. Check that water emerges! The device is not ready for operation.
6. The device switches on and off as required.
7. Maintenance

Danger!  Prior to all work on the device:

• Disconnect the mains plug.
• Ensure that the device and connected accessories are depressurized.
• Repair and maintenance work other than that described in this section should only be carried out by qualified specialists.

Regular maintenance

• Check device and accessories for damage, in particular electrical and pressurized components, and repair if necessary.
• Check suction and discharge lines for leaks.
• Clean the intake filter and filter element (if installed) and replace if necessary if the conveying capacity decreases.
• Check the pilot pressure of the pressure vessel (3) (equipment-specific) and increase it if necessary (see section 9.4 Increasing the pilot pressure).

If there is a risk of frost

Caution!  Frost (< 4 °C) destroys the pump and accessories as both always contain water!

• Disassemble the pump and accessories and store them in frost-free conditions (see the following section) if there is a risk of frost.

Disassembling and storing the device

• Switch off the device. Disconnect the mains plug.
• Open the discharge line (open the water tap or spray nozzle), allow water to drain off completely.
• Completely drain the pump (2) and vessel (3) as follows:
• unscrew the water drain screw (5).
• remove the suction and discharge lines from the device.
• store the device in a frost-free room (min. 5 °C).

Set pressure switch (HWW 3500/25 G
only. Contact the Metabo service team for setting all other HWW models.) Danger! Risk of electric shock at the terminals on the pressure switch! Only trained electricians should open the pressure switch and carry out changes. The pressure switch is pre-set on site for the most common application areas and can be adjusted as follows if required:

Note:  Adjustment of the main pressure spring (11) results in almost proportional changes in the cut-in/ cut-out pressure, the difference in pressure remains unchanged. An adjustment of the difference in pressure (12) only changes the cutout pressure, the cut-in pressure remains unchanged.

1. Switch off the pump, turn off at the mains, and ensure that no voltage is carried.
2. Remove the cover from the pressure switch.
3. Changing cut-in pressure: adjust main pressure spring (11) (SW 9 mm; 1 rotation ca. 0.1 – 0.15 bar). This adjustment also changes the cut-out pressure to a practically proportional extent!
4. Changing cut-out pressure: adjust (12) pressure difference. The cut-in pressure remains unchanged.
5. Mount the cover on the pressure switch and check professional installation.
6. Operate pump, check desired target value (7) on the manometer.
7. Repeat steps 1-6 if necessary until the desired values are set.

Caution!  The stated maximum pressure of the pump must not be exceeded. The cut-in pressure of the pressure switch must always be at least 0.2 bar over the precharge pressure of the chamber (1.5 bar, see Chapter 9.4). To prevent regular switching of the pump, the chosen pressure difference should be as high as possible (e.g. pre-set at ca. 1.8 bar).

Troubleshooting

Danger!

• Prior to all work on the device:
• Disconnect the mains plug.
• Ensure that the device and connected accessories are depressurised.

Pump does not run

• No mains voltage.
  • Check the on/off switch, cables, plug, socket and mains fuse.
• `Mains voltage too low.
  • Use an extension cable with an adequate conductor diameter.
• Motor overheated; motor protection relay has tripped.
  • After cooling the pump will switch ON again.
  • Ensure that there is adequate ventilation, keep air slots free.
  • Observe the maximum supply temperature.
• Motor hums, but does not start.
  • If repairs are required, see Chapter 11.
• Pump clogged or defective.
  • Disassemble and clean the pump. Clean the diffuser and replace if necessary. Clean the impeller and replace if necessary. See section 11.
• Line/inlet pressure greater than pump cut-in pressure.
  • A pressure regulator should be installed upstream, see Chapter2.

Pump not drawing in correctly or running very loudly:

• Lack of water.
  • Ensure that there is an adequate supply of water.
• Pump not sufficiently filled with water.
  • See section6.7.
• Suction line leaking.
  • Seal the suction line, tighten the screw couplings.
• Suction height too high.
  • Observe the maximum suction height.
  • Insert the check valve, fill the suction line with water.
• Intake filter (accessories) obstructed.
  • Clean and replace if necessary.
• Check valve (accessories) blocked.
  • Clean and replace if necessary.
• Water discharge between motor and pump, shaft seal leaking. (Minor discharge of water (max. approx. 30 drops per day) is normal with the use of shaft seals).
  • Replace the shaft seal. See section 11.
• Pump clogged or defective.
  • See section 9.1.

Pressure too low or pumps runs continuously (continuous switch-on/ off):

• Suction line leaking or suction height too high.
  • See section 9.2.
• Pump clogged or defective.
  • See section 9.1.
• HWW…: pressure switch adjusted.
  • Read off the switch-on and switch-off pressure on the pressure gauge (7) and check the values (see section 13 Technical Specifications). Please contact Metabo Customer Service if a modification is required. See section 11.
• HWW…: pump starts up even after a small volume of water is removed (approx. 0.5 l).
  • Check whether the pilot pressure in the pressure vessel is too low. Increase the pressure if necessary. See section 9.4.
• HWW…: water is running out of the air valve.
  • Rubber bellows in the pressure vessel are leaking, replace them. See section 11.

Increasing the pilot pressure (only HWW…)

If – in the course of time – the pump starts up even after the removal of a small volume of water (approx. 0.5 l), the pilot pressure in the vessel must be restored.
Note:  the vessel pilot pressure (air pressure) cannot be read on the pressure gauge (water pressure) (7).

1. Disconnect the mains plug.
2. Open the discharge line (open the water tap or spray nozzle), allow water to drain off completely.
3. Unscrew the plastic cap on the front face of the pressure vessel; the air valve is located behind it.
4. Mount the air pump or compressor hose with a “tyre valve” connection and pressure gauge on the air valve.
5. Pump up to the specified pilot pressure (1.5 bar; see section 13. Technical Specifications).
6. Connect the device again and check it works.
