GROUNDING INSTRUCTIONS
To prevent electric shock and death from incorrect grounding
wire connection read and follow these instructions:
Check with a qualied electrician if you are in doubt as to whether the outlet is properly grounded.
Do not modify the power cord plug provided with the tool. Never remove the grounding prong from
the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a
service facility before use. If the plug will not t the outlet, have a proper outlet installed by a qualied
electrician.
The tool must be plugged into an appropriate outlet, properly installed and grounded in accordance
with all codes and ordinances.
The outlet must be properly installed and grounded in accordance with all codes and ordinances.
Do not use extension cords with this pump.
Do not use an adapter to connect this pump to a different outlet.
The fuse must be a residual current circuit-breaker with a measured residual current of no more than
30 mA.
Make sure the power supply corresponds with the connection specications of the device before it is
connected.
This pump may only be used within the specied limitations for voltage and power, see the type plate.
Check the plug and cable before each use.
If the power cable is damaged, immediately disconnect the plug. Never use this device if the power
cord is damaged.
Unplug the power cord when the device is not in use or when transporting.

TECHNICAL SPECIFICATIONS
SETUP AND INSTALLATION
This device must be placed on a horizontal, rigid and level surface that is capable of supporting the
total weight of this device when lled with water. To prevent vibration or movement, place the device
on an elastic base support like a rubber mat. For stationary use, this device can be screwed down
rmly to the base with four screws.
When being used on garden ponds or swimming pools, this device must be set up to guard against
overowing and protected from being submerged.
the installation site must be well ventilated and protected against the effects of weather. If operating
this device indoors, you must ensure there is a drain in the ooring or a leak detection mechanism.
Before starting, check that the suction hose is sealed. Bubbles in the hose is an indication that there
may be leaks and may lead to device malfunction.
The suction line must be installed so that it does not exert any mechanical force
or tension on the pump. If the conveying medium is contaminated, a suction
lter must be used to pump from sand and dirt.
NOTE: A check valve is recommended so that the water does not run off when the pump is shut off.
All connections must be sealed with fermit paste or thread sealing tape to prevent leaks that cause
air exhaust and reduce or prevent water exhaust.
Hemp should be used in case of pipe threads from metal; synthetic thread must be sealed with
thread sealing tape.
All components of the suction line must be installed by a qualied technician.
The suction pipe should have an internal diameter of 25 mm and must be kink resistant and suitable
for vacuum use.
The suction line should be as short as possible, since the conveying capacity decreases as the
length of the line increases.
4

SETUP AND INSTALLATION
The suction line should ascend steadily toward the pump to prevent air pockets.
Sufcient water supply must be assured; the end of the suction line should always be in water.
All components of the pressure line must be compression-proof.
All components of the pressure line must be professionally installed.
DANGER: Avoid damage to the device. The suction line must be installed so
that it does not exert any mechanical force or tension on the pump.
The device can also be connected rmly to a pipe system (domestic water supply in the interior). In this
case, the device should be connected to the pipe sytem with elastic high pressure exible hose lines in
order to prevent vibrations.
DANGER: If components are not compression-proof or if they are improperly
installed, the pressure line can burst causing serious injury. Seek professional help if
you are unsure.
OPERATING THE DEVICE
1. Unscrew the pump cover
2. Fill completely with water
3. Reinstall the lter and screw on the pump cover and seal back on
4. To shorten the intake time, ll the suction line as well
5. Open the pressure line so the air can escape during intake
6. Switch the device on
7. When the water runs out evenly, switch the device off
For better performance, installing a check line valve between the pump and suction line is
recommended so that the water column remains in the suction line.
If Domestic Water Works is installed directly in the water distribution network, it is important that the
water pressure from this network is added to the pump pressure. A total pressure of 6 bar must not
be exceeded.
NOTE: The boiler includes rubber bellows, which is under air pressure from the manufacturer. This
enables small amounts of water to be removed without starting up the pump. Check the pressure
before operating the pump and increase if necessary. The pump must not be placed in direct sunlight
as this could result in too high pressure.
1. Plug in the mains plug
2. Open the pressure line (turn on the spigot or nozzle)
3. Turn on the pump at the ON/OFF switch
4. Check to be sure water is coming out.
If the motor does not start up or the pump does not build up any pressure or if similar faults occur, turn
the device off and try to remedy the error.
The pump is equipped with a pressure switch. This turns the pump on if the water pressure in the
boiler drops below the start-up pressure due to water removal. The pressure switch turns the pump
off when the shutoff pressure is reached.
NOTE: The pressure switch is preset to the correct start-up and shutoff pressure by the manufacturer.

OPERATING THE DEVICE
MAINTENANCE
NOTE: All gaskets must be renewed after each assembly. Make sure the device and connected
accessories are depressurized before carrying out any work on the device.
If over time, the pump starts up after a slight removal of water, approximately 0.5L, the preliminary lling
pressure in the boiler must be re-established.
1. Disconnect the mains plug
2. Open the pressure line (turn on the water spigot or nozzle), allow water to completely run off
3. Unscrew the plastic buttery valve on the front side of the boiler; the air-control valve is located
behind it.
4. Attach the air pump or compressor hose to the air-control valve with a “tire valve” connection and
pressure gauge.
4. Pump up, or inate to the designated preliminary lling pressure. Preliminary lling pressure: 1.8 ~
2.0 bar
Unscrew lter housing (A) and take out the lter cartidge
If necessary, soak the cartridge in warm water
Rinse the lter cartidge with clean water, brush out stubborn dirt from inside
the cartridge using a soft brush.
DANGER: If the conveyed water is highly contaminated, clean the water after
each use. A clogged lter may damage the device.

STORAGE
If there is danger of frost, dismantle the device and accessories, clean and store them in a place
protected from frost.
1. Turn off the device and unplug the mains plug
2. Open pressure line, allow water to completely run off
3. Completely empty the pump and boiler
4. Dismantle the suction and pressure lines from the device
5. Store the device in a frost free room, at least 5 °C
