Original Instructions
Hot water signifi cantly increas-
es the effi ciency of the cleaning
process – especially grease,
oils and fats can be broken
down more easily at higher
temperatures.
Temperatures up to 60°C
should clean off proteins, such
as blood substances.
In order to break down tough
layers of dirt, additional me-
chanical impact may be re-
quired. Special lances with
special nozzles (pulsating jet /
concentrated "0" jet) are avail-
As standard the system is
delivered without a detergent
injector and the optional, factory
mounted, internal chemical
system.
If you want to use detergents
or disinfectants these should
be dosed through an external
injector (see section 4.1.5) or
through the pump (see section
4.1.6).
The most effi cient cleaning
is reached with detergents in
conjunction with the high pres-
sure cleaning. For that purpose
Nilfi sk can off er you a series of
products specially developed
for high pressure cleaning,
among other fi elds within:
•
Cleaning of vehicles, ma-
chines, stalls etc.
•
Disinfection
•
Degreasing of workpieces
•
Descaling
The products are water-based,
without phosphates, and the
applied tensides (surface active
substances) comply with the
present requirements for easy
biodegradability.

Oil and traffi c fi lm should be
exposed to app. 70°C, whereas
grease and fat is easiest to
remove with temperatures of 80
to 85°C.
Several detergents become
more effi cient when acting with
hot water – please refer to
manufacturers recommenda-
tions.
able for such purposes as are
rotating brushes plus soft &
sand blasting equipment.
Please ask your Nilfi sk repre-
sentative.
Contact your Nilfi sk distribu-
tor for directions as to which
product(s) will fulfi ll your requi-
rements.
The method of application and
the dosage of the individual
products appear from the pro-
duct labels or the data sheet.
Low-foaming detergents are
applied through an injector and
under low pressure. A change
to cleaning under high pressure
is eff ected by regulating from
»low pressure mode« to »high
pressure mode« on the double
spray lance or by attaching a
high pressure spray lance.
For foam cleaning you will have
to attach a special foam equip-
ment. Insert the suction hose
of the injector into the foam
detergent.
Attach the foam lance on the
spray handle and now you are
ready for foam application.
Upon the application open the
by-pass cock of the foam injec-
tor and replace the foam lance
by a spray lance, and you are
ready for cleaning.
