OPERATION
-
Install a non-return valve at the end of the suction pipe.
-
Connect the suction pipe to the suction coupling tightly.
-
Fill the pump with water from the pressure pipe connection. If possible, open the non-
return valve slightly by pressing the valve part. This will make air discharge from the suc-
tion pipe and pump.
-
Place the suction pipe into the water (e.g. well).
-
Connect the pressure pipe to the pump tightly.
-
Plug the unit into power supply.
-
Switch on the pump with the On/Off-switch. After a while, water will start to flow from the
open pressure pipe. Let water flow in until air no longer comes from the pipe.
-
Check membrane operation regularly according to following instructions: close the pres-
sure side tap. After closing the pressure side tap, the pressure will start to rise in the wa-
ter line and after reaching the upper pressure (approx. 4 bar), the pump will shut down
automatically. When you open the water tap, water will start to flow but the pump will not
start running immediately (charging state), but the pressure will drop to approx. 2 bar
and the lower limit of the pressure switch will restart the pump again.
-
Check all connections to make sure there are no leaks.
WARNING! The pump must never run dry. The appliance must be switched off im-
mediately when water fails to flow.
WARNING! If the pump does not reach upper limit and shut down automatically,
turn off the pump with the On/Off-switch and refer to chapter ”Troubleshooting”.
If the pump runs a long time with the pressure side tap closed, water inside the
pump will warm up and damage pump parts.
Note
-
The diameter of the suction pipe/suction hose must be at least 1”. If the suction height is
over 5 m, it is advisable to use 1 ¼” suction pipe.
-
Prevent the suction pipe from being higher than the pump, as then it is hard to remove air
bubbles from the suction pipe.
-
Suction valve must be at least 30 cm below water level.
-
If the suction pipe is not tight, there is not enough suction to suck water.
-
Avoid using the unit with water that contains impurities (e.g. sand). If water contains im-
purities, install a filter to the suction pipe.
-
Switch off the unit with the On/Off-switch and disconnect the plug from the wall socket
always when the appliance is not in use.
-
Protect the unit from freezing during operation and storage. Never use it in cold condi-
tions. The unit (pump and water tank) must be emptied from water before storage: un-
screw the drain plug at the end of the pump, remove the pressure pipe from the tank and
drain all water. Store the unit in a dry and warm place.
