CH. 3 INSTALLATION (see Fig. 5)
MXC / 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). 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.
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.
CH. 4 ELECTRICAL CONNECTION
The single phase motors are protected from overloads by a thermal device installed in the winding. The
protection for the three phase motor must be installed by the user.
The following must be used as a conductor for the connection:
→
- outdoors cable H07RN-F
→
-
in inside areas cable H05RN-F or H07RN-F
For connecting single phase motors see Fig. 1
For connecting three phase motors see Fig. 2
For connecting double voltage single phase motors see Fig. 3

Electric shock risk
When installing, please ensure electropump is
disconnected from electrical supply.
Protect the electropump and all pipes from
bad weather or freezing conditions.
Ensure tension and frequency of electropump
(read plate) and power supply are same.
Installer must make sure that electric current
network has ground wire conforming to current
laws.
Make sure that electric current network is
provided with a high-sensitivity circuit breaker
,
=30 mA (DIN VDE 0100T739).
