MAINS WATER SUPPLY
!
Danger
Risk of injury! The appliance,
supply lines, high pressure
hose and connections must
be in perfect condition. If this
is not the case, the appliance
must not be used.
Connect the water supply
hose to the mains water
supply (Fig. 4A) and to the
coupling on the hydroblaster
(Fig. 4B).
Use a reinforced hose with a
diameter of > 1".
Check that the mains water
supply provides a sufficient
quantity and pressure of water
to operate the hydroblaster,
2 - 8 bars (29 - 116 PSI). (See
technical specifications table)
Maximum inflow water tempe-
rature 50°C. (122 °F).
ASSEMBLING THE ACCESSORIES
!
Important
Risk of injury. Use only original accessories provided or autho-
rised by the Manufacturer. Mount the accessories only when
the appliance is off.
Connect the high pressure hose to the hydroblaster (Fig. 4C)
and the lance (Fig. 5).
Information
The hydroblaster must be operated with clean water.
!
Danger.
Dirty or sandy water, or water containing corrosive chemi-
cals or solvents seriously damage the hydroblaster.
Failure to respect the above absolves the Manufacturer of all
liability and represents negligent use of the product.

Information
Respect the instructions provided by the water
utility company.
Current regulations specify that the appliance may not be con-
nected to the drinking water supply unless a suitable system
separator is fitted.
Use a suitable EN 12729 type BA system separator.
Water passing through a system separator is no longer classi-
fied as drinking water.
Connecting to a container or tank:
A pressure pump is required to supply the hydroblaster from a
container or tank.
!
Important
Do not connect the machine to a drinking water container.
!
Danger
Never suck up liquids containing solvents or acids in the pure
state, for example petrol, paint solvents or diesel.
The spray mist from the lance is highly inflammable, explosive
and poisonous.
Never use acetone, acids in the pure state and solvents as they
seriously damage the hydroblaster.
CONNECTING THE INERT
MEDIA SUCTION HOSE.
Connect the inert media suc-
tion hose to the coupling at the
base of the hopper. (Fig. 6).
The inert media may also
be supplied from an external
container using the special
suction nozzle available as an
optional accessory.
The suction hose must never
be longer than 10 m.
