This type of pumps settles generally in load, or what the level of the water would be over the
mouth of aspiration of the pump. In the case of facilities in aspiration it is necessary to make
sure a correct priming of the pump before the beginning and the installation must be provided
of a feet valve.
The pipes of plastic and the connections must be threaded with care.
If a hose is used to aspire, this must be of the non-comprimible type (with reinforcement spi-
ral).
The pipe/hose to aspire must be as short as it is possible to assure optimum conditions of
work.
It is recommended to install a valve for closing in both sides to isolate the pump.
Note: The pump does not admit the operation against closed spill valve, because this could
increase the temperature and the steam can damage the pump.
If the possibility that the work of the pump exists against a closed spill valve, it is a must to
make sure that a minimal volume of liquid pass through the pump, connecting a
bypass/bleed backflow valves to the unloading pipe.
In order to diminish the possible noise of the pump it is advised to place vibration-proof in
the mouths of aspiration, in the impulsion and between the base and the pump.
3.1 Ventilation
The motor of the pump cools off, through the fan located in its later part, by this reason, a
fresh air flow is necessary to make sure that a good ventilation of the pump is enough, and
making sure that the environmental temperature does not surpass 50º C.
In order to assure an efficient refrigeration it is essential that the minimal distance between
the fan cover and the wall or another obstacle located in the later part of the motor must be
upper to a twice of the diameter of the fan.
In closed spaces it can be advisable to install an additional fan that assures a fresh air flow
to the surroundings of the pump for its correct refrigeration.
Before retiring the cover of the capacitor holding box and before any transfer or dis-
assembling of the pump, be sure of that the electrical provision is disconnected.
The electrical connections must be realised by an authorized electrician and in agreement
with the local standard.
The pump must be connected to an external switch.
The votl and the frequency are wrote in the informative plate. Be sure that the motor is
adapted to this type of electrical provision.
The motor must be connected to the electrical provision as it shows into the diagram, using
an accredited watertight cable and in agreement with local norms and standards.
