CHAPTER 2
LIMITATIONS
WARNING
Electropump cannot be used to move inflammable or dangerous liquids, acids or corrosive substances.
WARNING
Ensure electropump never runs dry.
Note
The pump is suitable for use with drinking water for human consumption (Italian Ministerial Decree 174 and ACS). If the pump has been
assigned to uses other than water for human consumption, it may no longer subsequently be used for that purpose.
• Maximum liquid temperature: 50°C
• Maximum room temperature: 40 °C
CHAPTER 3
INSTALLATION (SEE FIG. 4)
DANGER - ELECTRIC SHOCK RISK
When installing, please ensure electropump is disconnected from electrical supply.
WARNING
Protect the electropump and all pipes from bad weather or freezing conditions.
DANGER
This appliance can be used by children aged 8 years or over and by persons with limited physical, sensory or
intellectual capabilities, or with limited experience and knowledge, provided that they are supervised or have
been instructed in the safe use of the appliance and are aware of the dangers involved. Children must not be
allowed to play with the appliance. Cleaning and user maintenance must not be carried out by children unless
they are supervised.
If installed for use with drinking water, clean the pump prior to installation - also clean if left unused for prolonged periods of time.
For drinking water, all materials used upstream and downstream of the pump must also be suitable for contact with drinking water for
human consumption.
• MULTINOX VE+ series electropumps
are not self-priming
• It is advisable to install it under the
level of the water
• If the electropump is to be installed
above the water level then a suction
pipe should be used with a diameter
equal to that of the suction duct for
electropump
• If the height HA is over 4 meters use a
tube with a larger diameter (Fig. 4)
• The suction pipe must not have
"goose- necks" or be inclined
improperly in order to avoid the
formation of air pockets
• Make sure that the pipe is perfectly
air tight
• At one end of the suction tube install a
foot valve with filter (1)
6
• Max. ON/OFF cycles/hour:
40 cycles qually spaced
• Maximum suction height: 6 m
• The pipe should be submerged at least
50 cm. into the liquid to be pumped
HI, in order to avoid the formation of
whirlwinds
• To avoid load loss on delivery, a pipe
with a diameter equal to or greater
than the intake of electropump should
be used
• It is advisable to install a non-return
valve directly on the delivery pipe,
this makes it possible to eliminate any
damage water hammers may cause to
the electropump (2)
• After the non-return valve an
interception valve should be installed.
The pipes must be placed so that
their weight does not interfere with
the electropump (3). The delivery and
suctions pipes must travel the shortest
distance with the fewest possible
number of bends
• Maximum operation pressure:
12 bar (MULTINOX VE+ 4-90 & 6-90)
16 bar (MULTINOX VE+ 4-120)
20 bar (MULTINOX VE+ 8-90 & 8-120)
• If the installation is fixed then the
electropump should be blocked on the
support surface
• In order to reduce installation vibration
the electropump should be connected
with a length of flexible tubing and a
layer of rubber or other anti-vibration
material should be inserted between
the electropump and the support
surface
• If the electropump is moveable
(equipped with a handle) it can be used
in a pool only if there are no people in it
and if the installation is equipped with
a shockproof switch
• Make sure that the motor is well
ventilated
