Translation of original Installation Instructions, english, KNF 125530-316634 06/18 7
Hence, make sure the temperature of the medium is sufficiently be-
low the ignition temperature of the medium, even when it is com-
pressed to the maximum permissible operating pressure of the
pump. The maximum permissible operating pressure of the pump
is stated in the technical specifications (Chapter 4).
If necessary, consider any external sources of energy, such as ra-
diation, that may add heat to the medium.
In case of doubt, consult the KNF customer service.
Store all replacement parts in a protected manner and dispose of
them properly in accordance with the applicable environmental pro-
tection regulations. Observe the respective national and interna-
tional regulations. This especially applies to parts contaminated
with toxic substances.
The pumps conform to the Directive 2011/65/EU (RoHS2).
The pumps conform to the safety regulations of the EC Directive
2014/30/EU concerning Electromagnetic Compatibility and the EC
Directive 2006/42/EC concerning Machinery.
The following harmonized standards have been used:
DIN EN 61010-1
DIN EN 61326-1 Class A
DIN EN 50581
The pumps correspond to DIN EN 60664-1:
The overvoltage category II
The pollution degree 2
The pump is maintenance-free. But KNF recommends, checking
the pump regularly with regard to conspicuous changes in noise
and vibrations.
Only have repairs to the pumps carried out by the KNF Customer
Service responsible.
Housing with voltage-caring parts may be opened by technical per-
sonnel only.
Use only genuine parts from KNF for servicing work.
Use only the original KNF power supply.

The pump is supplied by a universal power supply with inte-
grated overload
protection.
They are protected against overheating by a temperature sen-
sor on the motor board and equipped with overcurrent protec-
tion.
If one of these safety functions is triggered, the pump will
be
shut down and must be manually reset, as follows:
Separate pump from mains.
Remove the cause(s) of the fault before restarting.
