SAFETY
This manual contains basic information on the
installation, operation and maintenance and should
be followed carefully. It is essential that these
instructions are carefully read before installation or
commissioning by both the installation crew as
well as those responsible for operation or
maintenance. The operating instructions should
always be readily available at the location of the
unit.
This manual provides general information
concerning the pumping unit but does not
include detailed instructions for the drive
units (diesel or electric motor); these
instructions can be found on the specific
manuals which must be provided with this
manual and form an integral part of it.

the controls and optical signals
on machine board in addition to
performance of the cleaning,
adjustment and maintenance
operations and topping up of
liquids.
The pumping units equipped with
diesel engine and/or with vacuum

pump hazardous media, care
must be taken that, when
draining the leakage, personnel
and environment are not
endangered.

INSTALLATION
The pumping unit may be transported and stored in
a horizontal position.
Always lift the pumping unit
by its lifting system; never
use the delivery or suction
pipe or the hooks on the
pump and/or on motor unit.
WARNING! Make sure that
the pump cannot roll or fall
over and injure people or
damage property
During towing in the site,
check that the tow bar is fixed
by means of the stop pin and
that the latter is locked through
the locking device.
Although fitted on wheels, the
pumping unit is not approved
for use on roads.
Towing is therefore forbidden
on public roads.
On specific request, the
pumping unit can be fitted on a
trolley approved for road use.
During handling on site, ensure
that the diesel tank (fitted on
pumping unit base stand) is not
subjected to impact or abrasion
which can cause fuel leakage.
The pump is frost-proof as long as it is operating. If
the pump doesn’t work when the temperature is below
the freezing point, the water freezes and the pump
housing can break.
Never leave the water in the priming chamber if there
is the risk of freezing: empty the pump through the
inspection cover.
For longer periods of storage, the pump must be
protected against moisture and heat.
After a long period of storage, the pump should be
inspected before it is put into operation. Pay special
attention to the shaft seal and the drive unit.
Follow the instructions under the heading “Before
starting” in the chapter “Operation”.
TRANSPORTATION AND STORAGE
WARNING!
Handling equipment
Always pay extra attention to
safety aspects when working
with lifting equipment.
Suitable lifting equipment is
required for handling the pump.
The lifting equipment shall be
able to hoist the pumping unit
straight up and down preferably
without the need for resetting the
lifting hook.
Oversize lifting equipment could
cause damage if the pump
should stick when being lifted.
Make sure that the lifting
equipment is securely anchored
and in good condition.
Check that the lifting system is
in good condition.
- Stay clear of suspended
loads
- Always lift the pump by its
lifting handle
In order to guarantee adequate
stability of the pumping unit and
prevent it from accidentally
moving during operation, it must
be installed in a flat position
longitudinally and with a
maximum gradient of 10%
crosswise. You should therefore
avoid positioning it on steep
ground.
