• Measure the level of the input voltage and compare it to
the machine specifi cations.
• Turn on the circuit breakers -F1, -F2 and -F3.
• Turn on the overload protection units for the MPU´s and
the frequency inverter -F4 to -F10.
• Close the E-box and turn the two locks to locked position
by using the supplied key.
A.5 High pressure connection
IMPORTANT: When connecting to a pipeline always use
the fl exible hose connection from the outlet of the machine.
The outlet of the machine can be connected to a pipeline
with fi xed outlet points.
The pump station and outlet points should be placed so that
the lines become as short as possible.
• The line should be arranged with as few bends as possible.
• Sometimes it may pay to split the line close to the pump
station so the lengths conducting large volumes of water
become as short as possible. A centre location of the pump
station in relation to the outlet points would also lead to
smaller pipe dimensions.
• Pipe lines should be placed on walls of tile or concrete,
otherwise great care should be taken (reinforcement
plates etc.)
• Pipe lines should be placed so that damage is prevented
(collision, frost, extreme attacks of corrosion, etc.)
• Pipe lines should be fi tted in a visual location everywhere
or so that they may easily be inspected. Lines should not
be incorporated in walls or fl oors. When leading through
walls be careful not to enclosed. (Special lead-in bushes
are available)
• The outlet points should be placed as close to the opera-
tion point as possible and so that a hose length preferably
of 20 m is used.
It is recommended to let a service tech ni cian authorized by
Nilfi sk prepare the pipeline.

A.6 Venting
Start the machine and open all high pressure cocks on the
pipeline until all air has escaped. Start with the re motest
high pressure cock.
Please note that the cock should be closed for a short time
before opening it again. The latter is done in order to pre-
vent the leakage stop from being activated when venting
long pipelines.
Note! The machine may be protected with an antifreeze
from the factory. If antifreeze in the machine - catch the
fi rst litres until the fl uid is clear water. Collect the water in a
container for re-use.
B - Operation
B.1 Connections
B.1.1 High pressure hose on pipe system
The Nilfi sk high pressure hose with imprinted max. working
pressure and temperature should be attached to the outlet
connection of the pipe system by the quick coupling (1).
Danger of scalding!
Never dismount high pressure hoses at water temperatures
above 50°C.
IMPORTANT: Prior to dismounting of the high pressure hose
the machine should be stopped and the shut-off cock closed.
Then activate the trigger of the spray handle to relieve the
high pres sure hose of pressure.
B.1.2 Spray handle - accessories
1. Pull forward the quick coupling trigger (1) of the spray
handle.
2. Insert the nipple of the spray lance (2) in the quick cou-
pling and release the trigger.
