3. OPERATING INSTRUCTIONS
Purpose of use
This equipment is designed for use in systems for watering and spraying green areas, vegetable beds
and gardens and as well as for watering beds by spraying. This garden water-station allows you to
maintain pressure in the hose which enables the equipment to be used also a part of waterworks systems,
particularly to increase and then maintain the low pressure in these systems etc. The pump can be left
running even for prolonged periods of time. The water-station is not designed for pumping drinking water.
This equipment is not designed for use in commercial, trade or industrial applications.
Special design elements provide this pump with the capability to maintain constant pressure.
Inside the pressure tank (11), there is a pliable reservoir containing liquid. The rubber reservoir’s pliable walls
are exposed to the air pressure.
When the motor is turned on, the pump starts to feed liquid in the rubber reservoir to fill it gradually.
Simultaneously, the air inside the pressure tank (11) is being pressed and when a certain pressure value is
reached (depending on the factory preset value), the pump motor will be stopped by the automatic switch (10).
The liquid in the tank is under pressure (created by the air contained in the reservoir and acting on the
pliable reservoir walls) required the waterworks system operation. While the water is being drained out of
the reservoir (i.e. when the water taps are open etc.), the pressure inside the rubber reservoir as well as
inside the pressure tank (11) drops. If the pressure drops by 1.4 bar, the automatic switch (10) turns the
pump motor back on and the pump starts pumping water into the system until the automatic switch (10) is
activated again (thus stopping the motor).
This procedure takes place repeatedly, thus allowing the required pressure to be kept in the water-supply pipe
system.
If the pump is connected to a pressure system containing another pressure boosting device, it should be
taken into account that the existing pressure in this system and the pressure made by the pump are summed
up. The total pressure value should not exceed 10 bar.
NOTE: Before using the water-station, please first carefully read all the safety and operating instructions for
the pump. Only after reading these instructions will you be able to safely and reliably use all the functions of
the water-station. You must conform to all local regulations in force in your country. These regulations are
effective together with the particulars specified in these instructions.
ATTENTION! If you will be using the pump near pools or garden ponds, or in their protective zone, the
electrical grid must be equipped with a circuit breaker.
The water-station must not be used, if there are people in the pool or garden pond! Also do not use it if there
are fishes or other living creatures in the pool or garden pond.
The submersible pump is designed to pump water at a maximum temperature of 35 °C.
The pump must not be used for other liquids, particularly motor oils, cleaning agents and other chemical
products!

Putting into operation | Maintenance and storage
4. INSTALLATION
Install the equipment on a firm and level surface. The pump should be positioned as close as possible to the
water level but with safety clearance observance.
Pressure tank
To ensure correct function of the equipment, a back pressure of about 1.4bar should be kept inside the pressure
tank (11). If there is a pressure drop in the tank, connect a pump or a car tyre compressor to the overpressure
valve (13) and pressurize the air until the pressure inside the pressure tank (11) has returned to a desired level
required for the waterworks system to operate.
Connecting the suction hose (not included in the
package) [F1]
The suction hose diameter should not be smaller than
the inlet hole (4).
The inlet hole is equipped with 1” female thread. Screw
the suction hose with 1” male thread onto the orifice.
)

A check-valve should be always mounted on the suction hose end. [F2] (c). A check-valve (c) is a type of valve
which allows the fluid to flow in one direction only to prevent a reverse flow.
The suction hose must be installed with a slight gradient towards the inlet hole to prevent the creation of
air locks. The hose should be reasonably long. If the hose is too long, it may partially keep afloat, making
the pump malfunction. Correct installation should look exactly like in figure F2. Make sure that the suction
hose connection is absolutely air-tight; this will prevent the formation of closed air locks and ensure normal
equipment operation. Make sure that the suction hose is absolutely air-tight and fully immersed in water.
It’s recommended to use a suction hose equipped with a strainer.

What to do "When..."
Connecting the output hose
The output hose diameter should be selected in
a manner to fit the flow rating and pressure required at
the water supply points.
The output hose is connected to the aggregate with
a 1” female screw joint (not included in the package)
which must be screwed onto the output threaded hole
(1). [F3]
)
)
It is recommended to install a check valve [F2] (b) (not included in the package) between the output hole (1)
and the stop valve to regulate to flow rate (a) to prevent the occurrence of dangerous water hammers in case of
a sudden pump stop. This measure is obligatory if the expelled water column height exceeds 20m.

Technical specifications | Disposal
Initial filling - flooding the pump
WARNING! Do not put the water station into operation unless the pump is flooded to prevent the motor
seizure resulting from melting its parts by overhearing - dry operation.
WARNING! The pump should be flooded before being put into operation. Do not put the water station into
operation unless it’s fiĺled with water!
Before starting the pump, fill it completely with clean water through the supply/de-aeration orifice (3).
Unscrew the filling tube orifice plug (2) and fill the pump with water. You can also fill the pump directly
through the output hole.
Then screw the filling tube orifice plug (2) back.
The initial pump filling procedure should be repeated whenever the equipment has been left unused for
a prolonged period of time or whenever air gets inside the system.
NOTE: Make sure that the pump is fully flooded along the entire length of the suction hose.
5. PUTTING INTO OPERATION
To turn on
1. Connect the suction and output hose properly.
2. Fill the pump housing with water through the filling hole after the plug has been unscrewed.
3. Open the output pipes.
4. Connect the mains cord and set the switch in the “ON” position.
5. The suction procedure will start automatically.
To turn off
Set the switch to the “OFF” position.
ATTENTION! The initial pump flooding procedure should be repeated whenever the equipment has been
left unused for a prolonged period of time or whenever air gets inside the system.
It is required that the aggregate operation should be checked and the problems should be fixed in time to prolong
the aggregate lifetime and increase its efficiency.

6. MAINTENANCE AND STORAGE
ATTENTION! Before starting any jobs on the equipment itself, please unplug the mains cord from the
power outlet.
Both the equipment and the venting holes (if present) should be kept clean. Regular cleaning and
maintenance will ensure efficiency and prolong the equipment lifetime.
If the equipment fails even if the production procedure was strictly adhered to and subsequent rigorous test
were made, please have the equipment repaired at your authorized customer’s service centre.
Keep all nuts, bolts and screws tightened. This will ensure conditions for the safe operation of the equipment.
For safety reasons, replace worn out or damaged parts.
Always use only original spare parts. Parts that have not been supplied by the manufacturer may not be
sized appropriately and may cause injury.
It is required that the equipment should be stored in a dry room out of reach of children and at a safe
distance from any flammable materials.
Outer surfaces should be cleaned with a soft brush and a piece of cloth. Do not use solvents or polishing
pastes. All dirts must be removed.
The equipment may be damaged by frost unless all liquid is drained. The equipment must be stored in an
environment where the temperature does not drop below the freezing point.
