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 prevent 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 in long and winding pipe runs.
Piping should never rest its weight on the pump.
Sealing adhesive should not be used to seal pump connections. Use sealing tape for this purpose.

3.4. Electrical connection.

CONNECTING THE PUMP TO THE MAINS (Fig.1)

The electrical installation shall have a multiple separation system with contact opening ≥3mm.
The protection of the system shall be based on a differential switch (Iŋ=30 mA).
The electrical connection shall be made by connecting the pump socket directly to a domestic power socket duly protected according to the regulations in force in each country. The electrical connections must be made according to IEC-60364 (electrical installations in buildings) or according to the regulations in force in the country of destination.

Single-phase motors have built-in thermal protection.

3.5. Checks prior to initial start-up

Check that the mains voltage and frequency correspond to those indicated on the nameplate.
Make sure that the pump shaft rotates freely.
Fill the pump body completely with water through the filler plug. If you have installed a foot valve, fill the suction pipe.
Make sure that there are no leaking seals or fittings.
THE PUMP MUST NEVER RUN WITHOUT WATER.
The electrical installation must be effectively grounded and must comply with current national regulations.

4. STARTING

4.1. Start-up and operation

Open all shut-off valves in the system, both suction and discharge.
Switch on the power supply. The LINE voltage indicator lights up.
The pump-motor unit starts automatically. During operation of the pump, the (RUN) indicator lights up.
During this operation, keep a water outlet tap open to purge the air from the installation. Once the installation has been purged, close the tap and the unit will stop after ± 10 seconds. Only the voltage indicator (LINE) will be illuminated.
If the pump is not properly primed or there is no water to feed it, the pump will stop after 10 seconds and the LED (FAULT) will light up. To complete the priming of the pump, press the (+) and (-) keys simultaneously, thus restarting the circuit and the 10-second timer.
With a water consumption of more than 2 l/min the pump is always running, below this consumption the control flashes the RUN LED to indicate that we are below the minimum flow rate and after about 10 seconds the pump stops.
If the motor does not work or does not extract water, try to find out the anomaly through the list of the most common possible faults and their possible solutions that we provide on the following pages.

4.2. Set point pressure adjustment.

To raise or lower the setpoint pressure, the pump must be running and the RUN LED must be permanently lit. By pressing and holding one of the two control buttons (+) or (-) the set pressure is varied.
The start pressure is set to 0.5 bar below the set pressure.

Control panel TECNOPLUS 15

Control panel TECNOPLUS 25

Fault: Error LED.
Run: Always on when the engine is running. If it flashes, it indicates low or minimum flow.
Line: Mains voltage indicator.
+ – : Set pressure adjustments.

Considerations:
The set pressure must be 10 m. (1 bar.) above the highest tap of the installation (H.max).

4.3. Fault detection / Automatic restarting

In the event that the electronic circuit detects a lack of water, it will stop the pump and the alarm LED will flash. The circuit will make 4 attempts to connect and if no attempt is successful in re-establishing the pressure due to lack of water, the circuit will remain in fault mode indefinitely until it is manually reactivated.

While the pump is stopped in fault mode, waiting for a retry, the alarm LED will be flashing and if 4 unsuccessful retries have been made, the alarm LED will always remain active.

The following graph illustrates the time that elapses between the different retries in the event of not succeeding in any of them.

Pressing the (+) and (-) buttons simultaneously resets the circuit.

7. MAINTENANCE

Our pumps are maintenance-free.
In times of frost, be careful to empty the pipes. If the pump is not to be used for a long period of time, it is recommended to dismantle it and store it in a dry and ventilated place.
WARNING: in the event of a fault, the pump must only be handled by an authorized service technician.
