4.1 Danger from the environment! Do not expose the device to rain. Do not operate the device
in a damp or wet environment. Do not use the pump in potentially explosive locations or near
flammable liquids or gases!
4.2 Danger from hot water!
Danger! Install a check valve at the suction connection (12)
to prevent water from flowing back into the suction line. This can reduce the following
danger: Hot water can cause damage and leaks on the device and the connection lines, allowing
hot water to escape. Danger of scalding!
Devices with the designation HWW...: if the shut-off pressure of the pressure switch cannot be
reached due to poor pressure conditions or a defective pressure switch, the water can heat up
within the device as a result of internal circulation.
Devices with the designation P...: do not operate the device against a closed discharge line for
longer than 5 minutes. Water that circulates inside the device is heated up. In the event of a fault,
unplug the device from the power supply system and allow it to cool. A specialist must check the
system to make sure it is in perfect working order before it can be used again.
4.3 Risk of electric shock! Never direct the water jet directly at the device or other electrical
components! Risk of fatal electric shock!
Always disconnect the device from the power supply system prior to installation and maintenance
tasks.
Do not touch the plug with wet hands! Always pull on the plug and not the power cable to
disconnect it.
Do not buckle, squeeze, drag or drive over the power cable or extension cables; protect them
from sharp edges, oil and heat.
4.4 Danger due to deficiencies or faults on the device!
Check the device for possible damage - especially the mains cable, mains plug and electrical
components before each use. Risk of fatal electric shock!
A damaged device must only be reused after it has been correctly repaired.
Do not attempt to repair the device yourself! Only specialists are permitted to repair pumps and
pressure vessels (equipmentspecific). Caution! To prevent water damage, such as flooded
rooms, caused by deficiencies or faults on the device:
-Provide appropriate safety measures, e.g. alarm device or collection tank with monitoring The
manufacturer is not liable for any damage caused by:
-Improper use of the pump.
-Overloading of the pump through continuous operation.
-Failure to operate and store the pump in a frost-free environment. -Unauthorised modification of
the pump. Repairs to electrical equipment may only be carried out by qualified electricians!
-Use of spare parts which have not been tested and approved by the manufacturer.
-Use of unsuitable installation materials (fittings, connection lines etc.).
Suitable installation materials: -pressure-resistant (min. 10 bar) -heat-resistant (min. 100°C).
When using universal swivel couplings (bayonet couplings), only use versions with an additional
securing ring to ensure safe sealing.
