General rules for addition of
detergents
5.6
Working methods
20
Nilfi sk cleaning equipment can
be used for all detergents and
disinfectants, which are suit-
able for high pressure cleaning
according to the prescriptions
of the supplier. (If using external
injector, section 4.1.5, the pH-
value should be between 4 and
14. If using addition of chemicals
through the high-pressure pump,
section 4.1.6, the pH-value
MUST be between 5.5 and 8.5).
Acid and lye should not be ap-
plied in a concentrated form.
Carefully observe the prescrip-
tions and guidelines of the
supplier, also the rules concern-
ing safety clothing and drainage
facilities.
Your high pressure hot water
washer has been developed for
cleaning according to the so-
called »2-step method«.
However, your high pressure
hot water washer must be
equipped with an external
detergent injector.
STEP 1
Application of detergent -
soaking.
STEP 2
High pressure cleaning.
In practice the working process
is laid down in accordance with
the actual job, but as a starting
point the following working me-
thod can be described for a job:
1. Apply detergent under low
pressure. The dosage is
chosen according to the
job which is to be carried
through, and the adjustment
is made on the dosing unit.
2. Await acting time. Let the
detergent act on the dirt/sur-
face for a short time prior to
pressure cleaning - usually a
few minutes.
3. High pressure cleaning. Cle-
an all surfaces under high
pressure.
4. Rinse afterwards, if neces-
sary. To make sure that resi-
Detergents, which are not exactly
prescribed for use in conjunc-
tion with high pressure cleaning,
must only be used upon a previ-
ous approbation from Nilfi sk and
the supplier.
The use of Nilfi sk detergents
ensures that machines, acces-
sories and detergents match,
which is the condition of an opti-
mal solution of a cleaning task.
Nilfi sk can off er you a wide range
of effi cient agents for cleaning
and disinfection. The products
are composed of substances
which combine effi ciency and
environmental considerations at
one and the same time.
dual impurities are removed
from the surface.
In connection with the working
process the optimum cleaning
will be reached by following
these 3 pieces of advice:
Advice no. 1
When using a detergent,
usually always apply it on a
dry surface. If the surface is
rinsed with water at fi rst, it may
be diffi cult for it to absorb the
detergent, and the result is a
reduced eff ect of the detergent.
Advice no. 2
When applying a detergent
on large vertical surfaces (i.e.
the sides of a truck) work from
below and upwards. Thus you
will avoid the detergent running
off the surface through grooves
and dark streaks appearing on
the surface whilst cleaning.
Advice no. 3
During the high pressure clea-
ning you should work so that
the high pressure water does
not run over the surface which
has not been cleaned yet. This
is to ensure that there is suffi -
cient detergent on the surface
when the high pressure water
hits the surface.
