Device-specific safety instructions

• Only pump clean water! Never pump sand or other abrasive media.
• The minimum flow per hour must be 80 l/h (1.3 l/min).
• These devices are not designed to be used to implement drip irrigation since the water flow is too low and the cooling of the device by the conveyed medium would no longer be ensured.
• If your device does not have an integrated pre-filter, a pre-filter is recommended in order to filter sand and small particles from the water.
• A non-return valve must be used between the suction hose and the suction connection. This prevents air in the suction hose.
• The suction hose conducts the water from the water source to the device. Connect the suction hose to the threaded connection. Pay attention to ensure that the connection of the suction hose is sealed, since leaks will influence the performance of the device and may even make suction impossible. The suction hose should have a minimum diameter of 25 mm (1″) and be bend and vacuum-resistant. It is recommended to use a suction hose with foot valve.
• Use Teflon tape to seal the connection (12–15 layers).
• Make sure that there is sufficient water available in the water source and the suction end of the suction hose is always under water.
• Since the maximum suction lift of self-priming pumps is 8 m, the height of the device above the water level at the extraction point may thus be a maximum of 8 m. The suction hose must be on a continuous rise from the water source to the pump in order to ensure that no air bubbles are formed in the hose that may interfere with the operation of the device. If the device does not have an integrated pre-filter, it is recommended to install a pre-filter between the suction hose and the suction connection.
• The connection for the pressure hose is located on the top of the device. A hose or pipe with as large a diameter as possible (at least 19 mm, ¾”) should be connected to the pressure connection.
• Smaller diameters lower the conveyancing performance of the device considerably. Use Teflon tape to seal the connection (12–15 layers).
• Remember that with a house irrigation system, the connected pipes are under permanent pres-sure. For this reason, the device must be connected to a permanent network using an armoured hose that is capable of withstanding this permanent pressure.
• The use of garden hoses or suction hoses on the pressure side of the device is forbidden if the pipe is under permanent pressure since the permanent pressure may cause wear and material fatigue and result in the hose bursting or tearing even after a short time. Garden hoses may only be used if the hose is not under permanent pressure, for example, after a cut-off valve or water tap, but only outside closed spaces.
• Do not expose the appliance to rain. Do not use the appliance in wet areas.
• Do not use the appliance in potentially explosive areas or in the vicinity of flammable liquids or gases!
• Do not direct the water jet at the appliance or other electrical parts! Risk of fatal injury due to electric shock!
• Lay the extension cable so that it cannot get into the liquid to be pumped.
• Do not install and switch on the unit when there are people or animals in the medium to be conveyed (e. g. swimming pool) or have contact with such.
• Do not leave the unit unattended. If leaving it for any period of time, unplug.
• Remember that moving parts may also be located behind ventilation and venting slots.
• Symbols affixed to your tools may not be removed or covered. Information on the device that is no longer legible must be replaced immediately.

Installation and commissioning

Installation

• The appliance must be installed on a horizontal and even surface with sufficient load-bearing capacity for the total weight of the appliance when filled with water.
• In order to avoid vibrations, the appliance should be placed on an elastic base (e. g. rubber mat).
• The appliance can be firmly attached to the base with 4 bolts for stationary use.
• When being used on garden ponds and swimming pools, the device must be set up so as to guard against overflowing and protect against falling in. Additional legal requirements must be observed.
• Use a pre-filter if there is not one integrated.
• The installation location must be well-ventilated and protected against the effects of weather.
• When operating indoors you must ensure that there is a drain in the floor or a leak prevention mechanism.
• Before starting up, check the suction hose to ensure that it is sealed. Bubbles of air in the suction hose are an indication that there may be leaks and may lead to failure of the device!

Connect the suction hose to the intake manifold

NOTICE! Risk of damage to the appliance! The suction pipe must be mounted so that it does not exert any mechanical force or tension on the pump. A suction filter must be used for contaminated delivery media in order to protect the pump against sand and dirt.

Note: In order to ensure that water does not run off when the pump is switched off, a non-return valve must be used on the suction side.

• All fittings must be sealed with a thread sealing tape (e.g. Teflon tape); Leaks cause air suction and reduce or prevent the water suction or the flow rate at the pressure side.
• Teflon tape should be used for metal pipe threads; plastic threads must be sealed using thread tape.
• All parts of the suction pipe must be assembled properly.
• The suction pipe should have an internal diameter of at least 25 mm; it must be kink resistant and suitable for vacuum use.
• The suction pipe should be as short as possible because the delivery rate reduces with increasing line length.
• The suction pipe should always slope upwards to the pump in order to prevent air pockets.
• Ensure that there is a sufficient water supply; the end of the suction pipe must always be in the water.

Connect pressure pipe

NOTICE! Risk of damage to the appliance!
The pressure pipe must be mounted so that it does not exert any mechanical force or tension on the pump.

• All fittings must be sealed with a thread sealing tape (e.g. Teflon tape); Leaks cause air suction and reduce or prevent the water suction or the flow rate at the pressure side.
• Teflon tape should be used for metal pipe threads; plastic threads must be sealed using thread tape.
• All parts of the pressure pipe must be pressureproof.
• All parts of the pressure pipe must be assembled properly.

The device may be permanently connected to a pipe network (e.g. for indoor house water supply). In this case, the device must be connected to the pipe network using flexible hoses in order to prevent vibrations. Additionally, a floor drain or leakage protection must be available.

DANGER: Danger of injury!

The pressure pipe can burst during operation due to parts which are not pressure-proof and due to incorrect assembly. Danger of injury due to liquid squirting out!

Note

• The appliance must be used only for supplying service water, e. g. WC, washing appliance etc.
• It must not be used for supplying drinking water.
• The device may not be connected in such a manner that the water for other uses is fed into the drinking water supply.

Electrical connection

DANGER:  Risk of fatal injury due to electric shock! Do not use the appliance in wet areas!

The appliance must be used only under the following conditions:

• The connection must be made to earthed sockets which have been properly installed, earthed and tested.
• Mains voltage and fuse must comply with the technical data.
• During operation for swimming pools, garden ponds and similar places, the machine must be equipped with a residual current circuit breaker (RCCB) with a design fault current of not more than 30 mA.
• The electrical connections must be splash-proof for operation outdoors; they must not lie in the water.
• Extension cables must have sufficient wire cross section; cable reels must be unwound completely.

Operation

Filling and suction

NOTICE:  Risk of damage to the appliance!
The pump should be filled with water at every new connection, or in the case of water loss and/or air induction. Extended operation without water (unattended dry running) destroys the pump!

1. Screw out the water filling screw together with its seal.
2. Pour clean water in slowly until the pump is filled.
3. If you wish to shorten the suction time, you should also fill the suction hose (only possible with foot valve).
4. Screw the water filler plug with seal back in again.
5. Open the pressure pipe (open the tap or spray nozzle) so that air can escape during suction.
6. Switch on the appliance.
7. Switch off the appliance when water discharges evenly.

Note

• The use of a non-return valve is essential in order to maintain the water column in the suction hose.

Operation

Pump and suction pipe must be connected and filled.

NOTICE:  Risk of damage to the appliance!
The pump must not run dry. There must always be sufficient supply medium (water) available.

NOTICE:  Risk of damage to the appliance! Water containing sand or contaminated water damages the pump. Then, the product will not be subject to warranty.
Therefore, use a pre-filter.

NOTICE:  Risk of damage to the appliance!
If the domestic water supply is directly connected to the mains water distribution network, it should be noted that the water pressure from this network is added to the pump pressure. A total pressure of 10 bar must not be exceeded.

Note: The pressure vessel contains a rubber bellows which is pre-charged at the factory (pre-charge pressure, ► Technical data); this makes it possible to draw small quantities of water without the pump starting.

• Before operating the pump, check the pressure and increase it if required. While doing this, the pump must be dry.
• Check the pressure at least four times a year.
• The pump must not be exposed to direct sunlight as too high a pressure can occur under certain circumstances.

1. Plug in the mains plug.
2. Open the pressure pipe (open the water tap and/ or spray nozzle).
3. Switch on the pump at the On/Off switch.
4. Check that water discharges.

If the pump does start, does not build up any pressure, or similar faults occur, switch off the appliance and try to rectify the fault (► Malfunctions and troubleshooting).
The pump is equipped with a pressure switch. This switches on the pump if the water pressure in the pressure vessel drops below the cut-in pressure due to water being drawn.
The pressure switch deactivates the pump when the cut-off pressure is reached.

Note: The pressure switch has been set by the manufacturer to the correct start-up and cut-off pressure.

• It may not be changed since otherwise the device may be damaged.
• A change in the pressure switch setting automatically results in a voided guarantee.

DANGER:  Risk of fatal injury due to electric shock! The pressure switch must only be opened and adjusted by specialists.

Maintenance

DANGER:  Risk of fatal injury due to electric shock! Unplug the mains plug before performing any work on the appliance.

DANGER:  Danger of injury! Check that the appliance and connected accessories are depressurised before all work on the appliance.

NOTICE:  Risk of damage to the device!
All gaskets must be renewed after each disassembly of components.

DANGER:  The system is under pressure!
Prior to every maintenance task, and before looking for faults, first unplug the plug from the socket. Make sure that the connection lines or tank of the device are no longer under pressure.

• To do this, open a consumer (water tap) and allow the water to drain fully from the system.
• Then all of your maintenance and cleaning work may be carried out.

Checking the pressure in the tank

To ensure proper operation of the device, the pressure in the tank must be checked regularly (three to four times a year). For this, the pump must be dry.

• To check the pressure, undo the valve lid (5) on the tank and connect an air pump with manometer to the valve.
• If the pressure is not set correctly, it must be corrected again (► Technical data). If the pressure is set incorrectly, the device does not function properly, and the membrane in the tank is then subjected to increased wear and tear, and can be damaged. Damages to the device on account of incorrectly set pressure in the tank are not covered in the warranty.

Note: The pre-fill pressure cannot be read on the installed manometer.

1. Pull out the plug.
2. Open the pressure pipe (open the water tap and/ or spray nozzle), let the water drain completely.
3. Unscrew the plastic cap on the front of the pressure vessel; the air valve is behind this.
4. Put an air pump or compressor hose with a “tyre valve” connection and pressure gauge on the air valve.
5. Inflate to the intended pre-charge pressure (precharge pressure: ► Technical data).
6. Reconnect the appliance and check functioning.

Rubber bladder removal

Disassembly

The rubber bladder in the tank is a part which wears out during use and must therefore be replaced if damaged.
The rubber bladder can be replaced as follows:

• Pull the plug
• Let the water drain
• Release pressure at the valve
• Remove flange
• Loosen valve
• Remove bladder
• Insert new bladder
• Reassemble in reverse order
• Set the pressure as per specifications.

Storing

• If there is a risk of frost, dismantle the appliance and accessories, clean them and store in a place protected from frost.

NOTICE! Risk of damage to the appliance!
