hoses or pipes which resist the overpressure levels stated in the technical
parameters.
Starting / Turn ON
Check if all previous steps were carried out according to the instructions.
Connect the device to a power supply and depress the switch. The pump
starts operating.
Turn OFF
Depress the switch again to turn off or disconnect from a power supply.
5. Maintenance
The pump needs low maintenance requirements. The proper manipulation
and cleaning may lead to a longer lifetime.
Warning
The device shall be disconnected from a power supply prior to any
maintenance. In case of a damage to the power cord, it shall be replaced by
the producer or authorized service technician (or other qualified individuals) to
prevent any danger.
Pump cleaning
In case the pump becomes clogged, try flushing it with clean water.
Disconnect the suction pipe first, then mount the water faucet to the output
nozzle and let the water run through the pump. Consequently, you may turn
the device on and off a few times (approx. 2-second intervals) to unclog the
pump. Then, follow the instructions to set up the pump again. Do not flush the
device with polluted water (such as water containing solid particles – dust
etc.)
Pressure tank air pressure control and refilling
The pressure tank air pressure control shall be carried out regularly,
approximately once every 3 months. Disconnect the device from a power
supply and open the output valve. After the water pressure in a tank fully
decreases, measure the back side valve pressure using a common
manometer. The pressure level should be 0,2bar lower than a starting
pressure. The starting pressure can be obtained from the device manometer.
If needed, refill the pressure to a requested level. Always control the pressure
in case the pump seems to toggle on and off very frequently. The pressure
