A.1 Temperature conditions
The machine should be installed in a frost-free room. This
applies to pump as well as pipelines incl. of outlet points.
Con cern ing outdoor outlet points it should be possible to
close and emp ty that part of the line which is exposed to
frost.
The maximum ambient temperature for the machine is
40°C.
A.2 Condition of distance
In consideration of the cooling system of the machine and
the accessibility of service, there must be free wall space
on both sides of the machine. To the right 500 mm at a
min i mum and to the left 150 mm at a min i mum.
CS UNO:
The recommended installation height for the machine
is max. 1700 mm measured from the upper edge of the
machine.
A.3 Wall mounting
CS UNO:
Only mount the machine on a solid wall construction
suited for the mounting of a ma chine. I.e. a concrete or
brick wall.
Do not mount the machine on a wall where it will cause
disturbances in neighbouring rooms (canteens, offi ces
8
etc.).
CS DUO:
Place the machine on a plane fl oor.
Machine feet have been mounted under the machine.
These must be adjusted so that the machine stands sta-
ble. The feet may be bolted to the fl oor.
A.4 Water connection
The water connection is made through a fl exible hose
connected to the quick cou pling on the water inlet (1) of
the machine.
The connection can be made to a water supply network
or an internal water sup ply. A shut-off cock should be
mounted on the water supply network in the immediate
vicini ty of the ma chine.
Max. water pressure: 10 bar
Min. water pressure: 1 bar
Max. water inlet temp.: See Technical Specifi cations.
If there is a risk of running sands or other impurities in the
inlet water, a sand fi lter (50 micron) should be mounted
beyond the internal fi lter of the machine (for further con-
nection data see section Tech ni cal Specifi cations).
Clean the water inlet fi lter (1) once a month.
A.5 Mains power connection
Connect the machine to an approved safety switch.
Check voltage, fuse, and cables according to Safety
Instructions.
Connection data conc. power consumption can be taken
from the model tag of the machine.
A.6 High pressure connection
IMPORTANT: When connecting to a pipeline always use
a fl exible hose connection from the outlet of the machine
(pos. 6) - order no. 6300843. Contact your Nilfi sk distribu-
tor for further information.
The outlet of the machine can be connected to a pipeline
with fi xed outlet points, or standard high pres sure hoses
can be connected directly to the outlet of the machine.
It is recommended to let a service tech ni cian authorized
by Nilfi sk prepare the pipeline.
A.7 Venting
CS UNO:
Turn main switch (2) to position - 1 -. Open the outlet
point. Push the green starting button (3).
SC UNO 5M-L: Switch main switch to position - I -. Open
the outlet point.
Let the water run until all air has escaped from the pump
(even water fl ow).
In the case of a recently installed sys tem, or if the pipeline
and the pump have been emptied in any other way, the
system should be vented by starting the pump and then
let the water run at each outlet point of the pipeline at
turns.
