I This apparatus may be used by children 8 years
or older and persons with reduced physical,
sensory or mental
experience and knowledge, if they are supervised
or receive adequate training on the safe use of
the apparatus and understand the dangers.
Children should not be allowed to play with the
apparatus.
Children should not perform the ordinary cleaning
and maintenance tasks without supervision.
J Be careful with
environments.
K Caution! Look out for accidental leaks.
Do not expose pump to bad weather.
L Caution! Avoid icing.
Cut out power supply before servicing pump.
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.
They are horizontal, multi-cell, centrifugal pumps,
comprising several mass turbines that achieve the
same flow at different pressures depending on the
number of turbines available.
These pumps are designed to operate with clean
water, free from particles in suspension and with a
maximum temperature of 35ºC.
The pump with a built-in TECNOPLUS electronic
pressure regulator comprises a retention valve, leds
and electronic control.
It has been designed to automatically start and stop
a pump and it varies the motor speed to keep a
constant pressure. The electronic control also
protects against dry runs.
While any of the valves are open, the pump
operates, and when these are closed the pump
stops.
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.
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.
