Never allow children to use the machine.
Children should be supervised to ensure that they do not play with the tool.
When the pump is being used in swimming pools and garden

ponds and in the protected areas around them, the provisions of DIN VDE 0100-702 and -738 must be observed.
The device must be supplied via a residual-current device (RCD) with a rated residual current of max. 30 mA.
The device must not be used if there are persons in the water.
When used for domestic water supply, the statutory water and waste water specifications according to DIN 1988 must be observed.
The following residual risks essentially remain when operating pumps and pressure vessels can-not be fully eliminated (depending on features) – even if safety meas-ures have been introduced.

Danger from the environ- ment!

Do not expose device to rain. Do not operate device in a damp or wet environment.
Do not use the pump in hazardous locations or near inflammable liq-uids and gases!

Danger: Hot water!

Danger! Install a check valve at the suction connection (4)
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 pump and the con-nection 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 pump as a result of internal circulation.
Devices with the designation P…: Operate the pump a max. of 5 min-utes against the closed discharge line. Water that circulates inside the device is heated up.
In the event of a fault, unplug the pump from the power-supply sys-tem 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!

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

Danger due to device deficiencies or malfunctions!

Before each use, check the device for possible damage – especially the mains cable, mains plug and electrical components. Risk of fatal electric shock!
A damaged device must only be reused after it has been correctly repaired.
Do not attempt to repair the pump yourself! Only specialists are permitted to repair pumps and pres-sure vessels (depending on features).
Caution! To prevent water damage, e.g. flooded rooms, caused by device malfunctions or deficiencies:

• Introduce suitable safety measures, e.g.: alarm system or collecting tank with monitor 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;
• unauthorized 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 °C).

When using universal swivel cou-plings (bayonet couplings), only use versions with an additional securing ring to ensure safe seal-ing.

Initial Operation

Setting pilot pressure
Set the pilot pressure before initial operation. See section 9.4.

Installation

The device must be positioned on a horizontal, flat surface that is suitable for the device weight with water filling.
To avoid vibrations, the device should not be bolted on but rather should be positioned on a resilient base.
The place of installation should be well ventilated and protect against weather influences. Protect against frost – see section 8.2.

For operation in garden ponds and swimming pools, the device must be installed in a flood-proof loca- tion and secured against falling in.
Additional statutory requirements must be taken into consideration.

Connecting suction line

• Caution! The suction line must be installed such 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
• necessary 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 (4) of the pump. Depending on the model, a check valve may already be integrated (see section

Technical Specifications).

Seal all screw-coupling with thread sealing tape. Leaks result in air intake and reduce or prevent the water intake.
The suction line should have an inside 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 inclusions.
A sufficient water supply must be guaranteed and the end of the suction line should always be under water.

 Connecting the discharge line

Caution! The discharge line must be installed such that no mechanical or twisting forces are exerted on the pump.
Seal all screw-couplings with thread sealing tape to prevent water discharge.
All components of the discharge line must be pres-sure-resistant and installed correctly.
Danger! If non-pressure-resistant compo-nents are installed, or assembly is incorrect, the discharge line can burst during operation. Inju-ries are possible if highly pressurised fluids are ejected!

Connection to a pipe network
To reduce vibration and noises, the device should be connected with flexible hose lines to the pipe network.

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

• Connect only to an earthed outlet that is properly installed, earthed and tested.
• Mains voltage, mains frequency and fuse protection must correspond to those stated in the

‘Technical Specifications’.

• The device must be supplied via a residual-current device (RCD) with a rated residual current of max. 30 mA.
• The electrical connections must not be underwater and must be located in a flood-proof area. The connections must be splashproof for outdoor use.
• Extension cables must have sufficient conductor cross sections. Unroll cable reels fully.
• National installation specifications must be observed.

Filling pump and suction

Caution! In the case of a new connection, water loss or air intake, the pump must be filled with water. Operation of the pump without water filling will destroy it!

• Unscrew water filling screw (5) including gasket.
• Slowly pour in clean water until the pump is filled.
• Screw in water filling screw (5) with gasket again.
• Open the discharge line (open water tap or spray nozzle) so that air can escape during suction.
• Switch on the device (see section 7.).
• When water emerges evenly, the device is ready for operation.

Note: The suction line does not need to be filled because the pump is self- priming. Depending on the length and diameter of the line, however, it may
take some time until pressure is built up. 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.

If the pump is blocked by foreign bodies or the motor is overheated, a protective circuit shuts down the motor.

Using the device

Pump (device designation P…)

Functional principle: the device runs as long as the on/off switch (8) is activated.
Danger! If the discharge line is closed, run the pump for a maximum of 5 minutes because otherwise overheating of the water in the pump can
cause damage.

1. Insert mains plug.
2. Turn on at switch (8).
3. Open the discharge line (open water tap or spray nozzle).
4. Check that water emerges!
5. When work is complete, turn off the device at the switch (8).

Domestic water system (device designation HWW…)

Functional principle: 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, which is under air pressure (pilot pressure) when delivered;
this permits the removal of small volumes of water without the pump starting up.

1. Insert mains plug.
2. Turn on at switch (8).
3. Open the discharge line (open water tap or spray nozzle).
4. Check that water emerges!

Maintenance

Danger! Prior to all servicing:

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

Regular maintenance

• Check device and accessories, in particular, electrical and pressurised components, for damage and repair if necessary.
• Check suction and discharge lines for leaks.
• If the conveying capacity decreases, clean intake filter and filter element (if installed) and replace if necessary.
• Check the pilot pressure of the pressure vessel (10) (depending on features) and increase it if necessary (see section 9.4 Increasing pilot pressure).

Danger of frost

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

• If there is a danger of frost, disassemble pump and accessories and store in frost-free conditions (see following section).

Removing and storing device

• Turn off at switch (8). Unplug mains cable.
• Open the discharge line (open water tap or spray nozzle), allow water to drain off completely.
• Completely drain the pump (7) and vessel (10) by:
• unscrewing the water drain screw (1).
• Remove suction and discharge lines from device.
• Store device in a frost-free room (min. 5 °C).

Troubleshooting

Danger!

• Prior to all servicing:
• Unplug mains cable.
• Ensure that the device and connected accessories are depressurised.

• Insufficient water.
  • Ensure there is a sufficient water supply.
•  Pump not sufficiently filled with water.
  • See section 6.7.
• Suction line leaking.
  • Seal suction line, tighten screw-couplings.
• Suction height too high.
  • Observe maximum suction height.
  • Insert check valve, fill suction line with water.
• Intake filter (accessories) obstructed.
  • Clean, replace if necessary.
• Check valve (accessories) blocked.
  • Clean, 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 shaft seal. See section 11.
• Pump clogged or defective.
  • See section.

Pressure too low or pump runs continuously:

• Suction line leaking or suction height too high.
  • See section 9.2.
• Pump clogged or defective.
  • See section 9.1.
• HWW…: Pressure switch incorrectly adjusted.
  • Read off switch-on and switch-off pressure at the pressure gauge (3) and check values (see section 13 Technical Specifications). If an adaptation is necessary, please contact Metabo Customer Service. See section 11.
• HWW…: Pump starts up even after removal of a small volume of water (approx. 0.5 l).
  • Check whether the pilot pressure in the pressure vessel is too low. Increase pressure if necessary. See section 9.4.
• HWW…: Water is running out of the air valve.
  • Rubber bellows in pressure vessel leaking, replace it.

Increasing 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 pilot pressure cannot be read off at the pressure gauge (3).

1. Unplug mains cable.
2. Open the discharge line (open water tap or spray nozzle), allow water to drain off completely.
3. Unscrew plastic cap on front face of pressure vessel; the air valve is located behind it.
4. Mount 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 (see section 13. Technical Specifications).
6. Connect device again and check operation.
