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 multistage centrifugal pumps,
made up of several in-line impellers which provide
the same flow rate with different pressures,
according to the number of impellers in place.
These pumps are designed to operate with clean
water, free from particles in suspension and at a
maximum temperature of 40ºC.
The TECNOPLUS 25 pump with built-in electronic
pressure regulator consists of a check valve,
indicator LEDs and electronic control.
It has been designed to automate the starting and
stopping of a pump, changing the motor speed to
maintain a constant pressure. The electronic control
also prevents dry running pump.
While a faucet is left running, the pump continues to
run; when faucets 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.
