Karcher HD 13/12-4 ST-H [31/357] High pressure installation

English 31

For installation, please follow the specifica-

tions of the VDMA sheet 24416 "High pres-

sure cleaners; fixed high pressure cleaning

systems; concepts, requirements, installa-

tion, testing" (the German version can be

procured from Beuth Verlag, Cologne,

www.beuth.de).

– The fixed pipe network and the installion

should be connected with a high pres-

sure line.

– The fixed pipe network should be

placed as straight as possible. High

pressure piping systems should be in-

stalled correctly with removable and

fixed clips, taking into consideration the

variation in length caused by the effects

of heat and pressure.

– In order to keep pressure losses in the

high pressure piping as small as possi-

ble, we recommend the following:

In regards to the above mentioned standard

values, the length of the pipes and the

number of direction changes and fittings

must be taken into account.

The detergent tank is set up in such a way,

that the bottom of the tank is located not

more than 2 m unter the unit.
