Inspection and maintenance of the device:
Body
Inspection: Verify that the body is clean and correctly fastened.
Cleaning: Clean the external body of the device with a damp cloth and a standard
dishwashing liquid.
Make sure that no liquid enters the plugs and switches or gets behind the control element/
upper part of the body!
Interval: Every year
Execution: Operator
Float valve
Inspection: Verify that it opens and closes correctly (sealing) and that the oating unit can
move freely.
Interval: Every 6 months (depending on the local lime content in the potable water)
Execution: Operator
Maintenance: Exchanging the oat valve.
Depending on the lime content/hardness degree of the potable water, the oat
valve may be prematurely damaged due to lime deposition. In this case, replace
the oat valve (available as accessory).
Interval: Depending on the lime content / hardness degree, in case of premature wear.
Execution: Competent operator / qualied installer

1.6 Troubleshooting
Proceed as follows:
1. Disconnect the device from the power supply (unplug).
2. Eliminate the defect, cf. possible malfunctions under ”What to do, if”.
3. Re-insert the plug into the appropriate socket.
- The plug must be readily accessible and not be covered!
4. Set the desired operating state.
What to do, if....
water leaks from the DN 50 drain pipe?
The oating unit of the oat valve rubs against the tank wall.
Place the oat valve in the center: correctly insert the oat valve in the bracket. Additional settings
are not required. Make sure that the reinforced hose is mounted without stresses!
The oat valve has become dirty during the pipe installation.
Set the control element of the device to ”Manual“.
Open a point of use and let the pump run about one minute to ush the valve and remove dirt.
Then, reset the control element to the desired operating state.
The oat valve is prematurely covered with limescale due to the hardness degree of the potable
water.
Check the oat valve’s function as described in chapter 1.5 “Maintenance”.
In case of premature wear, replace the oat valve.
the pressure gauge displays 0 bar and the LED ”Error” on the ow guard lights up?
The pump has run dry.
Verify the oat valve and its feed-in capacity. Check any shut-off valves possibly mounted in the
supply pipe. Then, restart the installation, cf. instructions for installation, chapter 2.1.

11
What to do, if....
the pump permanently starts at short intervals?
There is a leakage problem on the pressure side or a point of use is not leaktight.
Shut-off the stop valve on the pressure side of the device.
Check whether the pressure gauge shows a pressure drop and the pump starts again. If not, the
leakage problem is not due to the device but to the downstream pressure pipe.
In case of other malfunctions, contact your dealer/contractual partner.
If the device has to be removed from the wall bracket for troubleshooting or other works

1.8 Important information
General
This state-of-the-art product has been developed and manufactured with the greatest care. It
undergoes permanent quality controls. While observing the installation instructions, the present
instructions of use will help the user to become familiar with the device and to operate it in
accordance with the intended purpose. The instructions for installation and use include important
information for a safe, appropriate and economic operation of the device. Observing them is
necessary to ensure the device’s reliability and long service life as well as to avoid dangers.
The instructions for installation and use do not take into account the local provisions that have
to be observed by the operator. Do not exceed the values concerning the pumped uid and
temperature dened in the technical documentation and observe any other directives specied in
the instructions for use and installation. The type plate indicates the type series, the most important
