• The pressure loss in the supply
line must be held as low as pos-
sible by
- avoiding long supply pipes
- mounting low pressure resistance
ball valves and
- avoiding fittings with high pressure
loss.
• When installing the piping, take
care to avoid air traps.
• All pipe connections to the unit
must be clamp connections en-
suring simple maintenance and
dismantling of the station.
Max. allowed temperature of supply water: 70°C
Max. allowed pressure of supply water:
For an optimum functioning of the injec-
tor system, we recommend installing a
filter on the inlet to avoid impurities.

6.7. Air connection
Before the unit is connected to the air
supply, the pipe system must be care-
fully rinsed in order to remove coarse
impurities.
• The unit requires an air supply boosting
- an inlet pressure of minimum 6 bar
- a minimum capacity of 200 l/min.
• The air supply pipe is connected directly with
a quick fitting for easy dismantling. In all units
an inlet valve with 1/4" thread is fitted (layout
drawings).

Mainstation with user pack system
See drawing no 110005307.
Replace the User Pack containing product by one
with clean water; place the foam nozzle and open
the spray gun/outlet valve. The product inlet line is
now rinsed with clean water before use of another
product.

• Place the specially designed user pack in the
automatic holder.
• If changing to a different product when ending
the cleaning process, rinse the product inlet
line with clean water as follows:
• Place the can with detergent in the can holder
• Check the suction filter for impurities.
• Put the suction hose into the can below product
level and avoid suction of air.
• After pre-rinsing, check again that the hose is
sufficiently below product level and avoid suc-
tion of air during foam or spray operation.
• After use of and when changing product as well
as after use of the unit, remove the hose from
the can and rinse the product inlet line and
injector with clean water.
• The special hose fitted with spray gun/outlet
valve is connected to the outlet quick coupling
of the unit (layout drawing).
• Maximum hose length: 30 m.
• It is recommended only to use Nilfisk FOOD
hoses, which have been tested for resistance.
