Transport and storage
Note
If you store or transport the device improperly, the
device may be damaged.
Note the information regarding transport and storage of
the device.
Transport
Before
transporting the device, observe the following:
•
Hold onto the mains plug while pulling the power cable out
of the mains socket.
•
Do not carry the device by holding it at the power supply
cable or hose.
Storage
When the device is not being used, observe the following
storage conditions:
•
dry and protected from frost and heat
•
Protected from dust and direct sunlight
•
with a cover to protect it from invasive dust, if necessary
•
Put the protective caps on the water connections to protect
the inside of the device against dust and dirt.
If you do not use the device for an extended period of time, it
must be cleaned thoroughly after its last application and before
recommissioning. Deposits and residues could lead to start-up
difficulties.
For restart, please proceed according to the Start-up chapter.

Unpacking the device
1. Open the cardboard box and take the device out.
2. Completely remove the packaging.
3. Fully unwind the power cable. Make sure that the power
cable is not damaged and that you do not damage it during
unwinding.
Start-up
Positioning
The device is installed between a pump and one more
extraction points (e.g. a water tap or a garden sprayer). The
following conditions shall be applied:
•
The pressure switch must be connected at maximally 15 m
underneath the highest-level consumer.
•
The water temperature must not exceed 60 °C.
•
The device may be used in facilities with up to 10 bar
water pressure. You can install a pressure reducer
between pump and pressure switch if the pressure of the
pump exceeds 10 bar.
•
The site of installation is protected from weather exposure
and wet conditions.
Required pump pressure
The required operating pressure of the pump to be connected
depends on the height difference between pump and highest-
level consumer (hydrostatic pressure). For instance, a height
difference of 20 m requires a pump pressure of 2 bar. To
guarantee a failure-free operation, the pressure at which the
pressure switch switches the pump on should be 0.2 bar above
the hydrostatic pressure. The pump should be able to build up a
pressure that is at least 0.8 bar above the switch-on pressure of
the pressure switch.
