5. الإعداد والتثبيت

Proper installation is crucial for the optimal performance and longevity of your LMI Unidose pump. This pump is designed for above-ground installation.

5.1 تركيب المضخة

Securely mount the pump to a stable, vertical surface using appropriate fasteners. Ensure there is sufficient space around the pump for ventilation, maintenance, and access to controls and connections.

5.2 وصلات الأنابيب

خط الشفط: Connect one end of the provided tubing to the pump's suction port. Attach the foot valve to the other end of this tubing and place it into the chemical supply tank. Ensure the foot valve is submerged and positioned to avoid drawing air or sediment.
خط التصريف: Connect the other length of tubing to the pump's discharge port. Attach the injection valve to the other end of this tubing. Install the injection valve into the water line or system where the chemical is to be dosed. Ensure the injection point is downstream of any pressure-reducing devices and allows for proper mixing.
اتصالات آمنة: Use the provided tubing connections to ensure all tubing is securely fastened to prevent leaks and air ingress.

5.3 التوصيل الكهربائي

The LMI Unidose UD001-238NU operates on 115V AC. Connect the pump's power cord to a grounded 115V AC outlet. Ensure the electrical circuit is protected by a ground fault circuit interrupter (GFCI) if required by local codes.

Note: The pump has dual voltage capability. If converting to 230V, a different cord and internal wiring adjustments may be required. Consult a qualified electrician or the manufacturer for 230V conversion.

6. تعليمات التشغيل

6.1 تجهيز المضخة

Before initial operation or after maintenance, the pump must be primed to remove any air from the pump head and suction line.

Ensure the suction line and foot valve are submerged in the chemical solution.
Loosen the bleed valve (if present) or the discharge tubing connection at the pump head slightly to allow air to escape.
Turn the pump on and set the flow rate dial to maximum.
Allow the pump to run until a steady stream of chemical solution, free of air bubbles, emerges from the bleed point.
Tighten the bleed valve or discharge connection. The pump is now primed.

6.2 ضبط معدل التدفق

The flow rate of the UD001-238NU pump is manually adjusted using the single dial located on the pump's control panel. Rotate the dial to increase or decrease the desired chemical dosage. The flow rate can be adjusted from 1 to 24 GPD.

Turn the dial clockwise to increase the flow rate.
Turn the dial counter-clockwise to decrease the flow rate.

Monitor the chemical consumption and system performance to fine-tune the flow rate for your specific application.

7. الصيانة

Regular maintenance ensures the reliable operation and extends the lifespan of your metering pump.

7.1 الفحوصات الروتينية

فحص الأنابيب: Periodically check the suction and discharge tubing for kinks, cracks, or signs of wear. Replace damaged tubing immediately.
التحقق من الاتصالات: Ensure all tubing connections are tight and free of leaks.
صمام قدم: Inspect the foot valve in the chemical tank for blockages or debris. Clean as necessary.
صمام الحقن: Verify the injection valve is not clogged and is functioning correctly.
رأس المضخة: Keep the pump head clean and free of chemical residue.

7.2 التنظيف

If the pump is used with chemicals that can cause buildup, periodic cleaning of the pump head and valves may be necessary. Consult the chemical manufacturer's guidelines for appropriate cleaning agents. Always flush the pump with clean water before and after cleaning with other agents.

8. استكشاف الأخطاء وإصلاحها

This section addresses common issues you might encounter with your LMI Unidose pump.

مشكلة	السبب المحتمل	حل
Pump not drawing chemical / losing prime	Air leak in suction line or connections Foot valve clogged or not submerged المضخة غير معدة بشكل صحيح Chemical tank empty Excessive suction lift	Check and tighten all suction line connections. Clean foot valve; ensure it is fully submerged. Re-prime the pump (refer to Section 6.1). Refill chemical tank. Relocate pump closer to the chemical tank if possible.
Pump running but no chemical flow	Discharge line blocked or injection valve clogged Pump head valves (check balls) stuck or dirty System pressure too high for pump	Inspect and clear discharge line and injection valve. Clean pump head and check balls. Verify system pressure is within pump's maximum (80 PSI).
Inconsistent dosing	الهواء في النظام Fluctuating system pressure Worn pump head components	Ensure pump is fully primed and no air leaks. Install a back-pressure valve or pulsation dampener if needed. Inspect and replace pump head components if worn.
المضخة لا تعمل	لا يوجد مصدر للطاقة Damaged power cord or internal wiring	تحقق من مخرج الطاقة وقاطع الدائرة. Inspect power cord for damage. Contact qualified personnel for internal wiring issues.
