5. Setup uye Kuiswa
- Kukwidza: Select a dry, well-ventilated location for mounting the pump. The pump can be mounted horizontally or vertically. Secure the pump using the integrated mounting feet. Ensure the mounting surface is stable and can support the pump's weight and vibration during operation.
- Plumbing Connections:
- Connect the inlet side of the pump to your water source. The pump is self-priming up to 6 feet, but placing it as close to the water source as possible is recommended.
- Connect the outlet side of the pump to your distribution system. Use appropriate 3/8"-18 FNPT fittings and ensure all connections are tight to prevent leaks, especially given the high operating pressure.
- Consider installing a filter on the inlet side to protect the pump from debris.
- A flexible hose connection is recommended to reduce vibration and noise.
- Electrical Wiring:
- Ensure the power supply is 24V DC.
- Connect the positive (+) wire from the power source to the positive (+) terminal on the pump.
- Connect the negative (-) wire from the power source to the negative (-) terminal on the pump.
- Install an appropriate fuse (not included) in the positive line, close to the power source, to protect the pump and wiring. Refer to the specifications for maximum current draw (6.0A).

6. Operating Instructions
- Kutanga kwekutanga:
- Ensure all plumbing connections are secure and the inlet line is submerged in water.
- Open a faucet or outlet downstream from the pump to allow air to escape the system.
- Apply power to the pump. The pump will begin to prime and push water through the system.
- Once a steady stream of water flows from the open outlet and all air is purged, close the outlet. The pump's automatic pressure switch will detect the pressure build-up and shut off.
- Normal Operation: The pump is designed for on-demand operation. It will automatically turn on when a faucet or outlet is opened (pressure drops) and turn off when all outlets are closed (pressure builds up to 120 PSI).
- Run-Dry Protection: The pump is designed to run dry without damage. However, continuous dry running is not recommended and can lead to premature wear. Ensure a consistent water supply.
7. Kuchengeta
- Kugara Kuongorora: Nguva nenguva tarisa zvese zvakabatana nemapombi nemagetsi kuti uone kana zvakabata uye zviratidzo zvekusakara kana ngura.
- Inlet Sefa: If an inlet filter is installed, clean it regularly to prevent clogging and maintain optimal flow.
- Winterization (for cold climates): If the pump is installed in an environment where freezing temperatures may occur, it must be drained or winterized with non-toxic antifreeze to prevent damage. Disconnect inlet and outlet lines and allow water to drain completely, or flush with RV/marine antifreeze.
- Kuchenesa Pombi: Chenesa kunze kwepombi uchishandisa chizivisoamp cloth. Do not use harsh chemicals or immerse the pump in water.

| Dambudziko | Zvinogona Kukonzera | Solution |
|---|---|---|
| Pombi haibatike. | Hapana magetsi, fuse yakaputika, waya dzakasununguka, switch isina kunaka. | Tarisa magetsi, tsiva fuse, simbisa kubatana, uye edza switch. |
| Pump runs but no water flows. | No water in supply, air leak on inlet side, clogged inlet filter, pump not primed. | Check water source, inspect inlet connections, clean filter, re-prime pump. |
| Low flow or low pressure. | Clogged inlet filter, restricted plumbing, low voltage, worn pump head. | Clean filter, check for kinks/blockages, verify voltage, inspect pump head. |
| Pump cycles on and off rapidly. | Small leak in system, faulty pressure switch, insufficient accumulator tank (if installed). | Check for leaks, test/replace pressure switch, consider accumulator tank. |
| Ruzha rwakanyanya kana kudedera. | Loose mounting, air in system, debris in pump, worn bearings. | Secure mounting, purge air, check for debris, contact support if internal issue. |
