1. GENERAL INFORMATION

Please observe the following instructions to achieve
the best pump performance possible and a trouble
free installation.
Read these instructions before installing the
pump.
Save them for future reference.
The DRAINEX models are used for the drainage of
sewage water with particles in suspension, septic
tanks, etc. Passage of particles in the DRAINEX
200 models = 45mm (MAX) and in the DRAINEX
300 models = 60mm (MAX).
The maximum water temperature is 35°C.
All pumps have been manufactured in top quality
material, submitted to strict hydraulic and electric
controls.
Correct pump operation is assured providing
the instructions on electrical connection,
installation and use are strictly adhered to.
Failure to adhere to the instructions can
result in premature failure of the pump and
voiding of the warranty.
together with one of the
The pump cannot be used in a swimming-
pool while there are people bathing.
Do not put your hand or any object into the
suction or discharge mouth, since the
rotating impeller could cause serious injury or
damage.

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.
