1 . Preface
Nilfisk FOOD congratulates you with your low-pressure foam cleaning system, which fulfils the latest technical
hygiene requirements.
Prior to installation and start of operation please make sure that your operational staff reads the directions for
use. On operation as laid down in the directions for use you will achieve optimum cleaning and hygiene in your
factory and minimum requirement for maintenance and repair work.
The combination of a centrifugal pump and an injector offers the possibilities of automatic and manual:
a) - foam spreading of detergents
b) - rinsing off with water
2 . Connections to the Low Pressure System
2 .0 Directions for Mounting
The system must be mounted in
frost-free rooms only.
2 .1 Water Connection
a) Prior to connection to the sys-
tem the supply pipe should be
rinsed through carefully in order
to remove coarse impurities
and metal shavings.
b) The water connections for the
pump station are at the top of
the system (B on the layout
drawing on page 4-6).
c) It is important to ensure abun-
dant water - no less than 150 l/
min. per pumping unit. To meet
this requirement the diameter
of the supply pipe should be
minimum 1 1/4" (32 mm) at a
water pressure of 3,5 bar, and
at a water pressure lower than
3,5 bar the water pipe should
be minimum 1 1/2" (38 mm).
d) The system is equipped with a
filter on the supply pipe of the
pump.
e) The pressure loss in the supply
pipe should be kept as low as
possible which means that:
- unnecessarily long supply
pipes should be avoided
- low-resistant ball valves
should be used
- fittings with high pressure
loss should be avoided.
f) On pipe mounting care should
be taken that no air locks are
produced.
g) Max. allowed temperature of
inlet water: 70°C.
h) Max. allowed pressure of inlet
water for the pump station: 4
bar.
2 .2 Compressed-Air
Connection
a) Prior to connection to the
system the supply pipe should
be rinsed through carefully with
air in order to remove coarse
impurities and metal shavings.
b) The system should be con-
nected to a compressed-air
pipe or a compressor offering:
- an inlet pressure to the low-
pressure system of minimum
5 bar
- a minimum capacity of 500
l/min.
d) The compressed-air pipe
should be connected direct to
the system by a union to facili-
tate dismounting. All systems
are equipped with a closing
valve with 1/4" thread (com-
pressed-air connection for the
pump station) (A on the layout
drawing on page 4-6).

2 .3 Connection of Detergents
The supply of detergents are
either supplied from the User Pack
System, which can be delivered as
attachments fig 1 or from separate
standard cans fig 2. the supply can
also be established through piping
systems. (page 7)
CAUTION!
When changing between differ-
ent products in the User Pack
system, these must be rinsed
thoroughly with clean water .
