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 fi ll 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 fi rst 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 specifi ed 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 fi shes 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!
