Discharge Pipe Assembly; Electrical Connection; Pre-Start Checks - Espa DRAIN 100M Gebrauchsanweisung

3. INSTALLATION
3.1. Fixing
The pump must always be totally submerged
which will provide it with the necessary
cooling. If there is a lot of dirt at the bottom of
the water tank, and you are using a DRAIN
pump, it is important to install the pump at
least 5cm away from the bottom to avoid dirt
blocking the wet end.
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, if it is
necessary that the pump does not touch the
bottom, suspend it by a plastic cable fixed to
the transport handle.

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.
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 3mm
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.
NEVER MODIFY THE FLOAT SWITCH POSITION,
WHICH IS ADJUSTED BY THE MANUFACTURER.
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 nameplate.
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 8.
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.
5. MAINTENANCE
Under normal conditions these pumps 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.
ATTENTION: In the event of faults or damage
occurring to the pump, repairs or electric cable
replacement should only be carried out by an
authorised service agent.
