▪ Use the handle for lifting, lowering and transporting the
pump. Never carry or drag the pump by the power sup-
ply cable!
▪ It must be possible to attach lifting equipment safely.
The storage place and the operating space/installation
site must be accessible with the lifting equipment. The
set-down location must have a solid bearing surface.
▪ Attach the lifting gear to the handle using a shackle.
Only use lifting gear which has been technically ap-
proved.
▪ The routed power supply cables must allow safe opera-
tion. Check whether the cable cross-section and the
cable length are sufficient for the selected installation
type.
▪ The corresponding IP class must be observed when us-
ing switchgear. Install the switchgear overflow-proof
and outside potentially explosive areas!
▪ Avoid air intake into the fluid, use baffles or deflector
plates for the inlet. Air which has entered the system
can collect in the pipe system and lead to impermissible
operating conditions. Air pockets must be removed via
ventilation systems!
▪ A dry run of the pump is prohibited! Avoid air pockets in
the hydraulics housing or in the pipe system. Ensure the
water level never falls below the minimum. The install-
ation of a dry-running protection is recommended!

Indications for double pump operation
If several pumps are used in an operating space, min-
imum distances between the pumps and the wall must
be complied with. Here there is a difference in the dis-
tances depending on the type of system: Alternating
operation or parallel operation.

- parallel operation: min. 1 × d
Distance to discharge pipelines
A
- alternating operation: min. 1.5 × d
2
- parallel operation: min. 2 × d

Note on DN 50/65 combination flange
The Rocsan neo V06... is equipped with a DN 50/65
combination flange. The nuts on the combination
flange are factory-set to the DN 65 flange. For use with
a DN 50 flange, adjust the nuts at the flange. The
flange can be reset to DN 65 at any time!
Fig. 4: Adjust combination flange
‡ No accessories mounted on flange.
‡ Nut is freely accessible.
1. Push the nut inwards onto the small hole circle using a
screwdriver.
▶ The flange connection is reset to DN 50.

Maintenance tasks
After a storage period of more than 6 months, check
the oil in the sealing chamber prior to installation:

Screw plug sealing chamber
‡ Pump is not installed.
‡ Pump is not connected to the mains.
‡ Protective equipment has been put on!
1. Place the pump horizontally on a firm surface. The
screw plug points upwards. WARNING! Risk of hands
being crushed. Ensure that the pump cannot fall over
or slip away!
2. Unscrew the screw plug.
3. Place a suitable tank to collect the operating fluid.
4. Drain the operating fluid: Rotate the pump until the
opening points downwards.
5. Check the operating fluid:
⇒ If the operating fluid is clear, reuse operating fluid.
