Safety precautions
This symbol
following words "Danger" or "Warning" indicates the
risk level deriving from failure to observe the
prescribed safety precautions:
DANGER Warns that failure to observe
the pre cautions involves a risk
risk of
of electric shock.
electric
shock
DANGER Warns that failure to observe
the pre cautions involves a risk
of damage to persons and/or
things.
WARNING
Warns that failure to observe
the pre cautions involves the
risk of damaging the pump
and/or the facility.
Do not put your hand or any
object into the suction or
discharge mouth, since the
rotating impeller could cause
serious injury or damage.
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.
DRAIN series have been designed for the drainage
of infiltration water, empty water tanks or swimming
pools. DRAINEX series are used for the drainage of
sewage water with particles in suspension, septic
tanks, etc. The maximum water temperature is
35°C. Passage of particles up to 35mm.
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.
together with one of the
Failure to adhere to the instructions can
result in premature failure of the pump and
voiding of the warranty.
The pump cannot be used in a swimming-
pool while there are people bathing.
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. 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.
