Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Flojet 03526-144A Triplex Diaphragm Automatic Water System Pump. Please read all instructions carefully before use to ensure optimal performance and longevity of the product.
The Flojet 03526-144A is a self-priming triplex diaphragm pump designed for automatic water systems. It is capable of dry running without damage and features a permanent magnet motor with ball bearings. This pump meets ISO 8846 ignition protection standards.
Safety Information
- Always disconnect power before installing, servicing, or performing any maintenance on the pump.
- Ensure the power supply is a direct 12V DC source. The pump is not designed for switched DC power.
- Do not pump flammable liquids or operate in an explosive atmosphere.
- Protect the pump from freezing temperatures.
- Use appropriate eye protection and gloves during installation and maintenance.
Setup and Installation
Proper installation is crucial for the performance and lifespan of your Flojet pump. Refer to the official installation manual (PDF) for detailed diagrams and instructions. A link to the PDF manual is typically provided with your product documentation or on the manufacturer's website.
Mounting
Mount the pump in a dry, accessible location. The pump features soft, noise-absorbing mounts to reduce vibration and operational noise. Ensure the mounting surface is stable and secure.

Plumbing Connections
The pump is equipped with 1/2-inch snap-in port fittings for easy connection. Ensure all connections are secure to prevent leaks. No fittings are included with the pump itself; these must be acquired separately.

Electrical Connections
Connect the pump to a 12-volt DC power source. Ensure the wiring is correctly polarized (red to positive, black to negative) and adequately sized for the pump's 7.0 amp draw. Install an appropriate fuse in the positive line close to the power source. It is critical to use a "direct" DC power source, as the pump may not function correctly with "switched" DC power supplies (e.g., some computer power supplies).
Operating Instructions
The Flojet 03526-144A pump is designed for automatic operation. Once properly installed and connected to a water source and power, it will self-prime and maintain system pressure.
- Self-Priming: The pump can self-prime up to a 9-foot suction lift. Ensure the inlet hose is submerged in water for initial priming.
- Automatic Operation: The built-in pressure switch automatically turns the pump on when water demand is detected (e.g., opening a faucet) and off when the demand ceases and system pressure is reached (up to 50 PSI).
- Dry Running: The pump is designed to run dry without damage, which is beneficial if the water source runs out temporarily. However, prolonged dry running should be avoided.
- Pulsation Eliminator: A built-in pulsation eliminator ensures smooth water flow without the need for an external accumulator tank.

Maintenance
Regular maintenance ensures reliable operation and extends the life of your pump.
- Winterization: In freezing conditions, drain the pump and run it dry to prevent ice formation, which can cause damage.
- Leak Checks: Periodically inspect all plumbing connections for leaks. High pressure from the pump can sometimes expose weak points in existing plumbing.
- Strainer Cleaning: If an inline strainer is used, regularly check and clean it to prevent debris from entering the pump and affecting performance.
- General Inspection: Check electrical connections for corrosion or loose wiring. Ensure mounting screws are tight.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power; incorrect wiring; faulty pressure switch; motor issue. | Check power supply (ensure direct 12V DC); verify wiring connections; inspect fuse; consult a qualified technician if motor is suspected. |
| Pump runs but no water flow | Air in system; clogged inlet strainer; dry run (no water source); kinked hose. | Bleed air from system; clean inlet strainer; ensure water source is available; check hoses for kinks. |
| Pump cycles on and off frequently (short cycling) | Leak in plumbing system; faulty pressure switch; restricted flow. | Inspect all connections and fixtures for leaks; check for partially closed valves or clogged filters; if leaks are ruled out, pressure switch may need inspection. |
| Excessive noise or vibration | Loose mounting; hoses rattling; air in system. | Ensure pump is securely mounted; secure hoses to prevent rattling; bleed air from the system. |
| Low flow or pressure | Clogged strainer/filter; low voltage; partially closed valve; worn pump head. | Clean strainer/filter; verify 12V DC power supply; ensure all valves are fully open; inspect pump head for wear. |
