3.0 Connections
3.1 Water connection
The water input is connected at the back of the
machine. The machine can be connected directly
to the mains water supply, or it can work as a self-
priming unit*).
For direct water connection the inlet hose must be
at least 6 m long, and the water temperature must
not exceed 65°C. Please note that connection to
the public water supply may entail mounting of a
fl oat cham ber.
If there is sand or other impurities in the water, it is
advisable to provide an external water fi lter in ad-
dition to the internal fi lter situated behind the quick
coupling (see accessory catalogue).
3.2 Oil supply
Connect the hydraulic motor to a hydraulic supply
with a capacity of 43 I/min. by 94-100 bar.
If the return pipe pressure exceeds 1.5 bar the
drain pipe should be conducted sep a rate ly.

*) With cold water (up to 5°C) the cleaner will oper-
ate satisfactorily with up to a 5 metre dif fer ence of
level between cleaner and water supply. The pump
and the inlet hose must be connected to the water
supply before starting up. When working with hot
water (65°C) the cleaner must be below or on a
level with the point of water supply. Working with
hot water and connected to high pressure hoses
longer than 10 m or inlet hoses shorter than 6 m,
the cleaner must be equipped with a fl oat chamber.
The same applies if the outlet of the cleaner is con-
nected to a tube system.
