Handling; Installation; Fixing; Discharge Pipe Assembly - Espa DRAINEX 200 Manuel D'instructions

2. HANDLING

The pumps are supplied suitably packaged to pre-
vent damage in transit. Before unpacking, check
that the packaging has not been damaged or de-
formed,
Lift and handle the product with care and with
the right tools.

3. INSTALLATION

3.1. Fixing

The pump must always be totally submerged which
will provide it with the necessary cooling.
Ensure there is enough space for the free operation
of the float switch (fig.3).
The pump must never be supported by the
electric cable or the discharge line (fig.3).

3.2. Discharge pipe assembly

In cases in which the discharge run is lengthy or
sinuous, we recommend using lines with a larger
diameter than the discharge mouth, to avoid head
loss due to friction as much as possible and to
obtain the best hydraulic performance possible.
Install a check valve to the outlet of the pump and
you will prevent pipe from emptying each time
pump stops. The check valve must permit the
passage of solids.
Ensure that the pipe is not bent and that is correctly
secured to the outlet connection because, in
addition to preventing the desired flow, proper
pump operation will be hindered.

3.3. Electrical connection

The electrical installation must have an
effective earth and comply with the national
regulations in force.
The protection of the system will be based on
a differential switch (Δfn = 30mA) in addition
to a multi-pole isolator with a minimum 3 mm
contact openings,
Pumps assembled with a starting control box or
fitted with a capacitor are supplied ready for
operation.
In the case of three-phase pumps the user must
provide the protection system.

3.4. Pre-start checks

Ensure the voltage and frequency of the
supply corresponds to the values indicated
on the electrical data label.
Ensure that the pump is submerged as shown in
Fig.3.
THIS PUMP MUST NEVER BE DRY RUN.

4. STARTING

If there is a line valve, open it completely.
Connect the electrical panel plug into a socket. If there
is an appropriate level of water, the motor will
immediately start up.
Check that the absorbed current is the same as
marked on the name plate.
If the motor does not start or no water flows at the
end of the line, try to find the anomaly using the
troubleshooting guide in point 7.
In the case of three-phase pumps check that the
turning direction corresponds to the direction marked
by the arrow situated in the suction cone.
Contact with the rotating impeller may cause
serious injury.

5. MAINTENANCE

Disconnect the pump from the mains before
performing any operation whatsoever.
Under normal
require no special or planned maintenance.
During frosty periods, remember to drain the
line.
If the pump is not going to be operated for a
long period of time, it is recommended to
remove the tank, clean it and store it in a dry,
well ventilated place.
To unclog or clean the impeller, it is only
necessary to raise the suction cone. To do
this, unscrew the screws that fasten the legs.
The cover assembly must come off as a
whole (fig.4).
On the DRAINCOR, a 0.3 mm gauge must be
used when refitting to align the turbine with the
suction base (fig.4). For correct alignment of
the turbine, refer to the screws "A" marked on
that drawing.
ATTENTION: In the event of faults or
damage occurring to the pump, repairs
should only be carried out by an authorised
service agent.

When the pump is eventually disposed of, please
note that it contains no toxic or polluting material.
All main components are material identified to allow
selective disposal.
