2. Instruccions de seguretat

ADVERTIMENT: Failure to follow these instructions may result in electric shock, fire, serious injury, or death.

• Always disconnect power before servicing the pump.
• Assegureu-vos que la font d'alimentació coincideixi amb el volum de la bombatage (110 V).
• Do not operate the pump in an explosive atmosphere, such as in the presence of flammable liquids, gases, or dust.
• Protegiu les connexions elèctriques de la humitat.
• Do not pump flammable liquids or chemicals that are incompatible with the pump's materials (EPDM valves, Santoprene diaphragm).
• Assegureu-vos que hi hagi una ventilació adequada al voltant de la bomba per evitar el sobreescalfament.
• Mantingueu les mans i la roba solta allunyades de les peces mòbils.
• This pump is designed for water transfer. Do not use it for other fluids without consulting the manufacturer.

3. Configuració i instal·lació

3.1 Muntatge

• Mount the pump in a dry, well-ventilated area, protected from direct sunlight and freezing temperatures.
• Utilize the industry-standard mounting pattern for quick and secure installation. Ensure the mounting surface is stable and can support the pump's weight.
• Mount the pump with the head down if possible, to prevent potential leaks from dripping onto the motor.
• Allow sufficient space around the pump for ventilation and future maintenance.

3.2 Connexions de fontaneria

• Use appropriate threaded connections and fittings for your system. The pump is supplied with multiple fittings for seamless integration.
• Ensure all connections are tight to prevent leaks and air ingress, which can affect pump performance.
• Install a filter on the inlet side to protect the pump from debris.
• The pump is self-priming up to 6 feet (1.5m) suction lift. Position the pump as close to the water source as possible for optimal performance.
• Avoid kinks or sharp bends in the hoses, which can restrict flow.

3.3 Connexions elèctriques

• Connect the pump to a 110V AC power supply. Refer to the pump's label for specific voltage i requisits actuals.
• Ensure the electrical circuit is protected by an appropriately sized fuse or circuit breaker.
• All electrical wiring should be performed by a qualified electrician and comply with local electrical codes.
• Protegiu totes les connexions elèctriques de l'aigua i la humitat.

4. Instruccions de funcionament

4.1 Posada en marxa inicial

1. Ensure all plumbing and electrical connections are secure.
2. Open any valves in the discharge line to allow air to escape.
3. Enceneu la font d'alimentació a la bomba.
4. The pump will begin to prime itself. Once water flows steadily and all air is purged from the system, close any open valves in the discharge line.
5. The built-in automatic pressure switch will stop the pump once the system reaches its shut-off pressure (200 PSI).

4.2 Funcionament automàtic

• The pump's automatic pressure switch will activate the pump when the system pressure drops (e.g., when a faucet is opened) and deactivate it when the pressure is restored (e.g., when a faucet is closed).
• This provides on-demand water flow and prevents unnecessary motor wear.

4.3 Run-Dry Safe Feature

• The pump is designed to be run-dry safe, meaning it will not be damaged if the water supply runs low or is depleted. However, continuous dry running is not recommended and should be avoided if possible to prolong pump life.

4.4 Funcionament silenciós

• The SEAFLO 31-Series pump is engineered for low noise and vibration, ensuring a disruption-free experience in RV and marine environments.

5. Manteniment

Regular maintenance ensures optimal performance and extends the life of your SEAFLO pump.

• Filtre d'entrada: Periodically inspect and clean the inlet filter to prevent debris from entering the pump and reducing flow.
• Connexions: Check all plumbing and electrical connections regularly for tightness and signs of wear or corrosion.
• Hivernització: In freezing conditions, drain all water from the pump and plumbing system to prevent damage from ice expansion. Running RV antifreeze through the system is also an option.
• Capçal de la bomba: Inspect the pump head, EPDM valves, and Santoprene diaphragm for any signs of wear or damage. Replace components as needed.
• Neteja general: Keep the exterior of the pump clean and free of dirt and debris.
