EBARA Ego easy Manual De Instrucciones Para Uso Y Mantenimiento página 8

Wherever anti-freeze is required, use anti-freeze fluids with
specific protective agents, as set out on standard UNI 8065.
In the event of installations on pre-existing systems, these
must be equipped with a magnetic cleansing filter with a
filtration capacity of no less than 500 microns and a magnetic
field of no less than 10,000 Gauss (e.g. IDRAMAG F). This
should be installed on the circuit and sized according to
the capacity of the circulation pump.
For installations on new systems, as an alternative to the
system mentioned above, you can also install magnetic
cleansing filters with a magnetic capacity of no less than
GB 1,000 Gauss (e.g. IDRAMAG or IDRAMAG FS). These
should be installed on a branch with a draining capacity of
approximately 10% of the system's total flow rate.
In both cases, you must ensure that the fluid has been
treated with suitable protective agents, as set out in
standard UNI 8065.
Any damage caused by solid, fibrous or abrasive substances
that cannot be attributed to a defect in the original product,
will INVALIDATE THE WARRANTY.
5.2 NOT INTENDED USE
All uses not specifically mentioned in 5.1 are generally
banned; in particular, the fluid must not contain aggressive
or explosive additives, mixtures of mineral oils and/or solid
or fibrous particles. The pump should not be used for
pumping flammable or explosive media, or in an explosive
atmosphere. To avoid formation of condensation in the
pump, fluid temperature must be higher or equal to the
ambient temperature.

7. INSTALLATION, DISMANTLING
AND TRANSPORT
7.1 GENERAL ARRANGEMENT FOR INSTALLATION
• The pump must be mounted with electromotor shaft
in horizontal position (fig. 3.1). Allowed and forbidden
positions are shown in fig. 3.2
• The arrow on pump plate shows direction of medium
flow
• If there is not enough space for electric connection,
control box can be rotated so that the connector is in
a horizontal position
• A position with the electrical connector vertically above
the motor is not allowed (see Figure 3.3c)
• Prior to rotating the electric motor part, close the shut-
off valves on the pressure and suction side of the pump
and unscrew the screws (Figure 3.3). Turn the electric
motor part as shown in Figures 3.3a or 3.3b.
7.2 DISMANTLING
In order to handle and dismantle the electropump you should:
a) Take off the power supply.
xx-60
b) Lift the electropump with suitable means according to
its weight and dimensions
7.4. TRANSPORT
The electropump is packed in a carton or, depending on
its weight and dimensions, it is fixed on a wooden pallet;
however, transport does not present many difficulties.
In any case, check the total weight imprinted on the box.
8. ELECTRICAL CONNECTION
8.1. PROTECTIVE DEVICES
• ALL THE CONNECTIONS MUST BE EXECUTED
ACCORDING TO THE LAW BY A QUALIFIED TECHNICIAN.
• ALL THE ELECTRICAL MASSES MUST BE CONNECTED
TO THE EARTH OF THE PLANT ACCORDING TO
THE ELECTRICAL STANDARDS IN FORCE IN YOUR
COUNTRY: THE INSTALLER SHALL BE THE SOLE
RESPONSIBLE FOR IT.
• FOR THE THREE-PHASE AND SINGLE-PHASE TYPES,
WE RECOMMEND INSTALLING A HIGH SENSITIVE
DIFFERENTIAL SWITCH (0.03 A).
After installing the unit check again the feeding cable
following the CABLE CONNECTION instructions and
connect it to the control panel (1) that must be fitted,
according to the actual rules, with:
