Electrical Connections - Master Pumps MPXP801 Traducción De Las Instrucciones Originales

Use a suction pump (2) with a diameter equivalent
to that of the suction mouth of the electropump (1).
If the height (HA) is over 4 meters use a tube with a
larger diameter. The suction line should be perfectly
airtight. No elbows and/or slopes should be present
to prevent the formation of air locks that could affect
the electropump efficiency.
A foot valve (3) with filter (4) should be fitted at
about half a metre below the fluid that has to be
pumped (HI) on one end
of the line.
It is advisable to install a check valve (6) directly on
the delivery line to prevent the electropump being
damaged by "water hammer".
A cut-off valve (7) should also be installed
downstream from the check valve, to facilitate
servicing operations. Piping should be fitted so that
vibrations, when existing, tension and weight do not
affect the pump. Piping should be routed along the
shortest and straighter track, avoiding an excessive
number of bends. Verify that the motor is properly
ventilated.
For permanent installations, it is advisable to fix the
electropump to the supporting base, connect the
system with a section of non flexible pipe and insert
a layer of rubber (or another anti-vibration material)
between the supporting base and the pump, in order
to reduce vibrations.
The site of installation must be stable and dry to
guarantee the stability of the pump.
Verify that the motor is properly ventilated.
ATTENTION!!!
Connection, suction and delivery pipes should
be connected with the utmost care. Make sure
that all connections fixed by means of screws
are sealed. Avoid applying excessive stress to
tighten the screws of connections or of
other components. Use a Teflon tape to
completely seal all joints.
The pump should be fitted in a stable position in
order to avoid falls and protect it from inundation.
Contact a specialised electrician.

Instructions for a safe pump start
Avoid exposing the pump to humidity. Protect the
pump from rain, making sure that there are no
leaking fittings over the pump. Avoid using the pump
in wet or damp environments.
Make sure that the pump and the electric
connections are protected from possible inundation.
Before using the pump, always inspect it visually
(especially power cables and plugs). Do not use the
pump if it is damaged.
If the pump is damaged, have it inspected by the
specialised assistance service only.
Do not transport the pump using the cable or use
the cable to remove the plug from the socket.
Protect the plug and the power cables from heat, oil
or sharp edges.

Start-up for models equipped with a switch
Before starting the pump, fill the suction pipe (2) and
the pump body (8) using the filling cap (9). Close the
cap after
verifying that there are no leaks. Open the closing
devices on the delivery pipe (i.e. the water cock) so
that air can be
released from the suction cycle.
Position the switch present on the terminal box
cover on "1" and insert the pump plug into a 230 V
alternate current
socket. The pump starts immediately.
* If your model is not equipped with a switch,
connect the outlet, the pump will start
immediately.
