Danger
14 (140)
Risk of fatal injuries on account of electric
voltage! Required electrical work must only
12 (120)
be performed by an electrical specialist.
– The socket must be secured through a
115-240
wrong current protection switch with a
1~
triggering current of 30 mA.
50/60
– This socket must be located close to the
12
work station so that the plug can be
40
pulled immediately in case of an emer-
IP 55
gency.

M22x1,5 – The interior cleaner is standard
equipped with spray nozzles that are
designed for a flow rate of 900-1200 l/h
G 1/2
(15-20 l/min) (nozzle set no. 2).
40
– If the high-pressure pump has a differ-
ent flow rate, the nozzles must be re-
1200
placed as per the table.
900
– The minimum pressure value of the reg-
ulating valve must be set prior to switch-
4,8
ing on the high-pressure pump. This
+2...+40
way, the interior cleaner will not be ex-
posed to pressure peaks when switch-
ing on.

Operation

Danger
Risk of injury on account of the escaping
water jet that could be hot!
– Only use the interior cleaner in closed
containers.
– Only insert the interior cleaner into a
container or switch it into another con-
tainer while the separate high pressure
pump and internal drive are turned off.
Danger
Risk of electric shock!
– Using the attached Velcro parts, posi-
tion the power supply so that is protect-
ed from water spray.
– Protect the extension cable from spray
water.
Note
Try to set up the interior cleaner in the cent-
er of an area.
Setting the immersion depth and in-
stalling the bracket
Insert the interior cleaner onto the ob-
ject to be cleaned using the container
hole cone on the support tube.
Loosen the screw connection at the
container hole cone.
Adjusting the immersion depth: Insert
the interior cleaner into the opening in
the container until the suction tube
touches the floor. Now lift up the interior
cleaner far enough (2-3 mm), until the
suction tube no longer touches the floor.
