POSEIDON 7 NEW-C3_en_Ver.1.0_33/12
Preface
This service manual contains detailed description of the main repair work on the cold HPW
POSEIDON 7.
Repair work requires a suitable testing workplace with the necessary water and power supply.
If operating errors are evident, refer the customer to the operating instructions.
A fault in the cleaner can have several causes as described in the section on troubleshooting.
Refer to the illustrated spare parts lists during repairs. They show the assembly position and the
sequence in which the individual components should be assembled.
See ”Technical Service Bulletin (TSB) sheets. They include information on technical
modifications that have been made after this repair manual was printed.
”Technical Service Bulletin” sheets are also valid as a supplement to the spare parts list until
publication of a new edition.
Repair manuals and ” Technical Service Bulletin” sheets should be available at the site
where repairs are carried out.
It is not permitted to give them to third parties.
Use original Nilfisk-ALTO spare parts only.

A
For your own safety
ESD measures
(electrostatic discharge)
Observe valid safety regulations
for electrical equipment. In
particular, observe the following
regulations:
IEC 60335-2-79
EN 60335-2-79
Additionally:
Also see national regulations
Before using the cleaner, always
read the operating instructions
and keep them readily available.
Repair work should be carried
out by persons instructed in
electrical installations or by
trained electricians only.
Take the following ESD precautions before carrying out any
repairs to the electronics:
 Touch the earth conductor before repairing the cleaner
( to discharge electrostatic charge from your body ).
 Wear wrist band if necassary.
 Use a conductive floor covering or a conductive table cover.
 Never touch the printed circuit board or electronic components
( always hold on to plastic ).
 Transport electronic components in conductive packaging
( e.g. ESD bag ).
