Safety precautions
This symbol together with one of the
following words “Danger” or “Warning” indicates the
risk level deriving from failure to observe the
prescribed safety precautions:
DANGER
risk of
electric
shock
Warns that failure to observe
the precautions involves a risk
of 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.
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 multicell centrifugal pumps,
composed of several turbines in series that obtain
the same flow rate at different pressures, depending
on the number of turbines arranged.
They are designed to work with clean water, free of
solids in suspension and at a maximum temperature
of 40º C.
The TECNOPLUS pump with regulator is composed
of a check valve, LED's for indication and control
electronics..
It has been developed to automate starting and
stopping and varies the motor speed to maintain a
constant pressure. The electronic control also
protects against running without water.
As long as any faucet is kept open, the pump will
keep running.
When the taps are closed, the pump stops running.
Proper adherence to the installation and operating
instructions and electrical wiring diagrams will
ensure proper operation of the pump.
Failure to follow the instructions in this manual may
result in motor overloads, reduced technical
characteristics,
shortened pump life and
consequences of all kinds, for which we decline any
responsibility.
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
These pumps are designed for indoor use.
Make sure that pump is never submerged and that it
rests in a dry and well aired room.
3.1. Fixing
The pump should be fixed to a solid base by means
of screws, taking advantage of the holes in the
support in order to avoid undesirable noise and
vibrations.
The pump should be protected from flooding and
provided with dry ventilation.
If you wish to fix the pump, use 2 Ø8 screws and take
advantage of the holes in the bracket.
3.2. Suction pipe assembly
The piping must have the same diameter or, if the
distance is more than 7 meters higher from the pump
inlet, a minimum upward slope of 2% must be
permanently guaranteed in order to avoid air pockets.
If the pump is installed at suction, it should be installed
as close as possible to the water level in order to
reduce the suction stroke to avoid head losses. It is not
recommended to install the pump more than 5 m.
geometric height from the water level. The installation
of a check valve at the suction base is recommended.
The suction pipe must be submerged at least 30 cm
below the dynamic water level.
3.3. Discharge pipe assembly
It is forbidden to install a check valve in the
rising main.
Assemble the Kitpres and pressure gauge
according to Fig. 5.
It is recommended to use pipes of the same diameter
as the delivery port or larger to reduce head losses
