4. Настройка і ўстаноўка
4.1 Мантаж
Mount the pump in a dry, well-ventilated area. The pump can be mounted horizontally or vertically. Use the integrated rubber feet to minimize vibration and noise. Ensure there is sufficient space around the pump for ventilation and access for maintenance.

4.2 Сантэхнічныя злучэнні
The pump has 1/2"-14 MNPT inlet and outlet ports. Use the provided 1/2" barbed hose adaptors for hose connections. Ensure all connections are tight and leak-free. It is recommended to install the 50 mesh inlet strainer on the inlet side to prevent debris from entering the pump.
- Уваход: Connect the water supply to the inlet port. The pump is self-priming up to 6 feet (1.8 m).
- выхад: Connect the outlet port to your water system.
- Avoid kinks or sharp bends in hoses that could restrict flow.

4.3 Электрычныя злучэнні
Connect the pump to a 12V DC power source. The pump comes with 16 AWG leads and a 2-pin connector.
- Connect the red wire to the positive (+) terminal of the 12V DC power source.
- Connect the black wire to the negative (-) terminal of the 12V DC power source.
- Install an appropriately sized fuse or circuit breaker (refer to specifications for max current draw) in the positive (+) lead, as close to the battery as possible.
5. Інструкцыя па эксплуатацыі
Once properly installed and connected, the pump operates automatically via its integrated smart pressure switch.
5.1 Пачатковы запуск і грунтоўка
- Ensure all plumbing connections are secure and the inlet strainer is clean.
- Open a faucet or outlet in your water system.
- Apply 12V DC power to the pump. The pump will begin to run, drawing water and pushing air out of the system.
- Allow the pump to run until a steady, air-free flow of water is achieved from the open faucet.
- Close the faucet. The pump's pressure switch will detect the pressure buildup and automatically shut off.
5.2 Аўтаматычная праца
The smart pressure switch provides automatic start and stop functionality. When a faucet is opened, the system pressure drops, and the pump automatically turns on. When the faucet is closed, the pressure rises, and the pump automatically turns off. This mimics the experience of home water usage.

5.3 Internal Bypass Technology
The pump incorporates internal bypass technology to regulate pressure and reduce frequent on/off cycling. This helps maintain a steady water flow and extends the pump's lifespan by reducing stress on components.

6. Тэхнічнае абслугоўванне
Рэгулярнае тэхнічнае абслугоўванне забяспечвае аптымальную прадукцыйнасць і даўгавечнасць вашага помпы.
6.1 Inlet Strainer Cleaning
Periodically inspect and clean the 50 mesh inlet strainer to prevent debris from entering the pump and restricting flow. A clogged strainer can lead to reduced performance or pump damage.
- Адключыце харчаванне помпы.
- Remove the strainer housing.
- Rinse the mesh screen under clean water to remove any accumulated debris.
- Reassemble the strainer, ensuring a tight seal.
6.2 Агульны агляд
- Check all plumbing connections for leaks. Tighten as necessary.
- Inspect electrical wiring for any signs of wear or damage.
- Ensure the pump is securely mounted and the rubber feet are intact.
6.3 Уцяпленне
If the pump will be exposed to freezing temperatures, it must be winterized to prevent damage.
- Drain all water from the pump and plumbing system.
- Alternatively, flush the system with non-toxic RV antifreeze.
