1. Introduction
The FORAS JA106N is a high-quality, self-priming centrifugal electric pump, proudly manufactured in Italy by PENTAX INDUSTRIES S.p.A. This pump is engineered for reliable and continuous operation, specifically designed for pumping clean water, even with air present, and non-aggressive chemical liquids. Its robust design and efficient performance make it ideal for various applications, including domestic water supply, garden and orchard irrigation, and pressure boosting systems in conjunction with small accumulators.
The JA106N model is particularly recommended for pressure accumulation where a small amount of water is required. It ensures a stable flow rate of up to 70 liters per minute (2.8 m³/h) and a maximum head of 51 meters.
2. Safety Instructions
Please read and understand all safety instructions before installing, operating, or performing maintenance on the pump. Failure to follow these instructions may result in serious injury, electric shock, or damage to the equipment.
- Electrical Safety: Ensure the pump is connected to a properly grounded electrical outlet with the specified voltage (230 V, 50 Hz). Do not operate the pump with damaged cables or plugs. Disconnect power before any maintenance or inspection.
- Installation Location: The pump must be installed in enclosed spaces or locations protected from atmospheric influences (rain, direct sunlight, frost). Ensure adequate ventilation around the motor.
- Water Temperature: Do not pump liquids outside the specified temperature range of 0°C to 50°C.
- Liquid Type: This pump is designed for clean water without solid particles and chemically non-aggressive liquids. Pumping other liquids may damage the pump and void the warranty.
- Children and Unauthorized Personnel: Keep children and unauthorized persons away from the pump during operation.
- Thermal Protection: The motor includes integrated thermal protection. If the pump stops unexpectedly, allow it to cool down before attempting to restart. Investigate the cause of overheating.

5. Setup and Installation
Proper installation is crucial for the pump's efficient and safe operation. Refer to local codes and regulations for plumbing and electrical connections.
- Location: Install the pump in a dry, well-ventilated area, protected from frost, rain, and direct sunlight. The pump should be placed on a stable, level surface to minimize vibration.
- Mounting: Secure the pump using appropriate bolts through the mounting holes on the base.
- Plumbing Connections: Connect the suction line to the 1-inch inlet and the discharge line to the 1-inch outlet. Use appropriate fittings and sealants to ensure watertight connections. The suction line should be as short and straight as possible, with a foot valve at the end to prevent water from draining back.
- Priming: As a self-priming pump, the JA106N is designed to evacuate air from the suction line. However, for initial startup, it is recommended to fill the pump casing with water through the dedicated filling screw before connecting to power. This assists in faster priming.
- Electrical Connection: Connect the pump to a 230 V, 50 Hz power supply. Ensure the circuit is protected by a suitable circuit breaker and that the pump is properly grounded. Consult a qualified electrician if unsure.

6. Operating Instructions
Follow these steps for safe and effective operation of your FORAS JA106N pump:
- Initial Priming: Before the first start, ensure the pump casing is filled with water. Open the filling screw, pour water until full, then securely close the screw.
- Power On: Connect the pump to the power supply. The pump will start automatically if connected to a pressure switch, or manually if controlled by a switch.
- Monitor Operation: Observe the pump during the first few minutes of operation. Ensure water is flowing smoothly and there are no unusual noises or leaks. The self-priming function will draw water and expel air.
- Continuous Operation: The pump is designed for continuous duty. However, avoid running the pump dry, as this can cause severe damage.
- Power Off: Disconnect the pump from the power supply when not in use or before any maintenance.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pump.
- Regular Inspection: Periodically check for any signs of leaks, unusual noises, or vibrations. Inspect electrical cables for damage.
- Cleaning: Keep the pump exterior clean and free from dust and debris to ensure proper motor cooling.
- Winterization: In areas prone to freezing temperatures, drain all water from the pump and plumbing lines to prevent damage from ice expansion. Use the dedicated drain screw for this purpose. Store the pump in a frost-free environment if possible.
- Seal Check: While the mechanical seal is designed for durability, monitor for persistent leaks around the shaft. If leaks occur, the seal may need replacement by a qualified technician.
8. Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power; Thermal overload tripped; Motor fault | Check power supply and connections; Allow motor to cool and reset; Consult a technician. |
| Pump runs but no water flows | Pump not primed; Suction line blocked or leaking air; Foot valve stuck; Water source empty. | Re-prime the pump; Check suction line for blockages or leaks; Inspect foot valve; Ensure adequate water supply. |
| Low flow or pressure | Partial blockage in suction/discharge; Air in system; Impeller worn; Incorrect pipe size. | Check for blockages; Bleed air from system; Inspect impeller; Ensure correct pipe dimensions. |
| Excessive noise or vibration | Cavitation (air in water); Loose mounting; Bearing wear; Foreign object in pump. | Check for air leaks in suction; Secure pump mounting; Consult technician for bearing/object removal. |
