2. Bezpečnostní pokyny

Always adhere to the following safety precautions to prevent injury and damage to the pump:

• Elektrická bezpečnost: Ensure the pump is connected to a properly grounded electrical outlet. Do not operate with damaged cords or plugs. Disconnect power before any maintenance or inspection.
• Teplota vody: Do not pump liquids exceeding 60°C (140°F). For household applications, the maximum fluid temperature is 35°C (95°F) as per EN 60335-2-41.
• Instalace: Install the pump in a dry, well-ventilated area, protected from direct sunlight and freezing temperatures. Ensure stable mounting to prevent vibration.
• Limity tlaku: Do not exceed the maximum operating pressure of 10 bar (6 bar for AGA 0.60-0.75-1.00 models).
• Kvalifikovaný personál: Installation and electrical connections should only be performed by qualified personnel in accordance with local regulations.
• Ochrana: The pump has IP44 protection, meaning it is protected against solid objects larger than 1mm and splashing water. It is not submersible.

3. Součásti a funkce

The AGC/I 1.50 T pump consists of several key components:

• Tělo čerpadla: Made of cast iron, providing durability and resistance to wear.
• Motor Axle: Constructed from AISI 303 stainless steel, ensuring corrosion resistance in contact with liquid.
• Impeller/Drive: Tecnopolymer for models AGA 0.60-0.75-1.00, embossed brass for other models, designed for efficient fluid transfer.
• Mechanická ucpávka: Carbon, ceramic, NBR for reliable sealing and prevention of leaks.
• Elektrický motor: Asynchronous 2-pole motor with forced ventilation, insulation class F, and IP44 protection. Available in single-phase (230 V ± 10% 50 Hz) and three-phase (230/400 V ± 10% 50 Hz) configurations.
• Inlet (DNA): 1 1/2 inch for this model (1 inch for AGA 0.60-0.75-1.00).
• Outlet (ID): 1 palců.

4. Nastavení a instalace

Správná instalace je klíčová pro výkon a dlouhou životnost čerpadla.

1. Umístění: Choose a dry, well-ventilated, and frost-free location. The pump should be placed on a solid, level surface to minimize vibration.
2. Montáž: Secure the pump firmly using appropriate bolts through the mounting holes on the base.
3. Sací vedení:
   • Use a rigid, non-collapsible pipe for the suction line.
   • Ensure the suction line is airtight to prevent air ingress, which can affect self-priming.
   • Install a foot valve with a strainer at the end of the suction pipe in the water source to prevent debris and maintain prime.
   • Keep the suction line as short and straight as possible, avoiding unnecessary bends.
4. Výtlačné potrubí: Connect the discharge pipe to the pump's outlet. Install a check valve if backflow is a concern, and a gate valve for flow control.
5. Elektrické připojení:
   • Ověřte, že napájecí zdroj objtage and frequency match the pump's specifications (230 V ± 10% 50 Hz for single-phase, 230/400 V ± 10% 50 Hz for three-phase).
   • Zajistěte správné uzemnění.
   • Install appropriate circuit breakers or fuses for overload protection.
6. Priming (Initial Start-up):
   • Before the first start-up, fill the pump casing completely with water through the priming port until it overflows.
   • Close the priming port securely.
   • The pump is self-priming, but this initial fill assists in faster operation.

5. Návod k obsluze

Follow these steps for safe and efficient operation:

1. Předoperační kontrola:
   • Ujistěte se, že všechny spoje jsou těsné a těsní.
   • Confirm the pump casing is filled with water (for initial start or after prolonged disuse).
   • Check that the suction line is submerged in the water source.
2. Spuštění čerpadla:
   • Open any valves on the discharge side.
   • Zapněte napájení čerpadla.
   • The pump will begin to draw water and self-prime. This may take a few moments.
3. Monitorování provozu:
   • Listen for unusual noises or excessive vibration.
   • Check for leaks around connections.
   • Zajistěte stálý průtok vody.
4. Zastavení čerpadla:
   • Close any valves on the discharge side if necessary.
   • Switch off the power supply to the pump.
5. Chod na sucho: Never allow the pump to run dry. This can cause severe damage to the mechanical seal and other components.

6. Údržba

Pravidelná údržba zajišťuje optimální výkon a prodlužuje životnost čerpadla.

• Pravidelné kontroly: Periodically inspect the pump for any signs of leaks, corrosion, or unusual wear.
• Čisté sítko: If a foot valve with a strainer is used, regularly clean the strainer to prevent blockages and maintain flow.
• Zima: In areas prone to freezing temperatures, drain the pump completely to prevent damage from ice expansion. Disconnect pipes and open drain plugs.
• Ventilace motoru: Ensure the motor's ventilation fins are clean and free from obstructions to prevent overheating.
• Profesionální servis: For internal component issues or complex repairs, contact a qualified service technician.
