INSTaLLaTION (SEE PICTUrE 1 - PaGE 73)
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 is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
• MULTINOX-XC / MULTINOX /
MULTINOX-VE / MCX 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
equamente distribuiti
• Maximum suction height: 5 m
(MULTINOX-XC; MULTINOX-VE; MCX;
MULTINOX)
• 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)
• Maximum admitted working pressure:
7 bar (MULTINOX; XC; MCX)
9 bar (MULTINOX)
9 bar (MULTINOX-VE)
• The delivery and suctions pipes must
travel the shortest distance with the
fewest possible number of bends
• 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
