4. Operating Instructions (Priming and Draining)

4.1 Priming tal-Pompa

Priming is the process of filling the pump with water to ensure it can create suction and operate efficiently. This is typically done before the first use or after the pump has been drained.

1. Ensure all connections to the pump (inlet and outlet pipes) are secure.
2. Remove the 1/4" NPT priming plug from the top of the pump.
3. Slowly fill the pump casing with water through the priming port until it overflows.
4. Reinstall the priming plug, hand-tightening it securely.
5. The pump is now primed and ready for operation.

4.2 Draining the Pump

Draining the pump is crucial for winterization or before performing maintenance to prevent damage from freezing water or to safely work on the pump.

1. Skonnettja l-Enerġija: Always disconnect the pump from its power source before draining.
2. Sib il-Plagg tad-Drenaġġ: Identify the 3/8" NPT drain plug at the bottom of the pump casing.
3. Poġġi l-Kontenitur: Position a suitable container beneath the drain plug to collect the water.
4. Remove Drain Plug: Carefully unscrew the drain plug. Allow all water to completely drain from the pump.
5. Store Plugs: If removing the plugs for an extended period (e.g., winter), store them in a safe place to prevent loss.
6. Reinstall (if applicable): Once draining is complete, reinstall the drain plug, hand-tightening it to prevent leaks.

5. Manutenzjoni

Regular maintenance of the drain and priming plugs ensures the longevity and reliable operation of your sprinkler pump.

• Spezzjoni O-Ring: Periodically inspect the O-rings on both plugs for signs of wear, cracking, or deformation. Damaged O-rings can lead to leaks. Replace them if necessary.
• Tindif: Clean the plugs and their respective ports during draining or priming procedures to remove any debris or sediment that could affect the seal.
• Ħażna: If the pump is stored for an extended period, ensure the plugs are clean and properly stored to prevent damage or loss.
