UNO/DUO BOOSTER
When con nect ing the high pressure hose directly to the
ma chine, the sys tem should be vented by starting the
pump and ac ti vat ing the trigger of the spray handle wit-
hout having attached the spray lance.
CS DUO:
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 as follows:
1. At fi rst start pump no. 1 and let the water run from an
outlet point of the pipeline.
When con nect ing the high pressure hose directly to
the ma chine, activate the trigger of the spray handle
without having attached the spray lance.
Let the water run until all air has escaped from the
pump (even water fl ow).
2. Stop pump no. 1. Then start pump no. 2 and let the
water run from an outlet point of the pipeline.
When con nect ing the high pressure hose directly to
the ma chine, activate the trigger of the spray handle
without having attached the spray lance.
Let the water run until all air has escaped from the
pump (even water fl ow).
3. Vent the pipeline by starting one pump and then let the
water run at each outlet point of the pipeline at turns
until all air has escaped from the system.
B - Operation
B.1 Connections
B.1.1 High pressure hose - directly on the machine
The Nilfi sk high pressure hose with imprinted max. wor-
king pressure and temperature should be attached to the
outlet connection of the machine (6) by the quick coupling
(a).
Max.extension hose: 50 m.
Danger of scalding!
Never dismount high pressure hoses at water tempera-
tures above 50°C.
IMPORTANT: Prior to dismount-ing 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 High pressure hose - to outlet point
In the case of a pipeline with fi xed outlet points the high
pressure hose with imprinted working pressure and
temperature should be attached to the nipple of the high
pres sure cock (1) by the quick coupling (2). Upon attach-
ment turn the handle of the high pressure cock (3) to
open position.
Danger of scalding!
Never dismount high pressure hoses at water tempera-
tures above 50°C.
IMPORTANT: Prior to dismounting of the high pressure
hose or when changing to another outlet point the high

pressure cock should be care ful ly closed. Then activate
the trigger of the spray handle to relieve the high pressure
hose of pressure.
B.1.3 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
coupling and release the trigger.
3. Pull forward the spray lance or any other accessory to
ensure correct mounting before starting the machine.
NOTE!
Clean nipple of any impurities each time the spray lance
has been dismounted.
B.1.4 Application of detergents (external)
If you want to apply detergents or disinfectants these
should be dosed to the water through an injector. In con-
junction with the injector it may be ad van ta geous to use a
wall rack on which spray lances, 2 pcs. of 25 l containers
as well as 10 m high pressure hose can be placed.
Below you will fi nd various types of outlet points with
injectors.
1. Outlet point with detachable injector
To be attached to the quick coupling of the high pressure
cock.
To be used for dosing of low-foaming detergents or disin-
fectants.
Dosage 1-8%.
2. Outlet point with detachable foam injector
To be attached to the quick coupling of the high pressure
cock.
To be used in conjunction with foam lance for application
of high-foaming de ter gents or disinfectants.
Dosage 1-5%.
3. Outlet point with cleaning trolley and foam injector
To be attached to the quick coupling of the high pressure
cock.
To be used in the same way as "Outlet point with detach-
able foam injector".
Makes it possible to place 4 spray lances, 2 pcs. of 25 l
containers as well as 20 m high pressure hose.
B.2 Start
The shut-off cock on the water inlet should be open.
CS UNO:
Turn the main switch (2) to position - 1 -. Press the green
starting button (3).
SC UNO 5M-L: Switch main switch to position - I -).
Check on the pressure gauge (5) that a pressure is being
built up in the system. If a pressure is not being built up,
vent the machine as de scribed in section A.7 Venting.
