Mounting and Securing

1. Step 1: Attach mounting bracket (1x) and secure with screws (2x) as shown in the diagram.
2. Step 2: Position the pump and secure its base to a stable surface using appropriate fasteners (e.g., 4x screws). Use a spirit level to ensure the pump is mounted horizontally.
3. Step 2A (JP/JP PM/JP): Secure the pump base using 4 screws.
4. Step 2B (JP PT-V/JP PT-H): Secure the pump base with the integrated tank using 4 screws.

Diagrams illustrate attaching mounting brackets and securing the pump base with screws, emphasizing correct orientation and stability.

Plumbing Connections

Ensure all pipe connections are made securely and correctly to prevent leaks.

1. Step 2a (JP): Apply thread sealant to the pipe threads. Screw the pipe into the pump inlet, tightening with a wrench. Ensure the pipe is not kinked or blocked.
2. Step 2b (JP PM): Connect the pipe to the pump inlet, ensuring proper sealing. Tighten with a wrench. The PM 1 controller is integrated into the system. Avoid kinks or blockages in the piping.
3. Step 2c (JP PT-V): Connect the inlet and outlet pipes to the pump and tank assembly. Ensure proper sealing and avoid pipe restrictions.
4. Step 2d (JP PT-H): Connect the inlet and outlet pipes to the pump and tank assembly. Ensure proper sealing and avoid pipe restrictions.

Diagrams show the process of threading pipes, tightening connections with a wrench, and illustrate correct vs. incorrect pipe configurations (e.g., avoiding kinks or sharp bends).

Priming the Pump

1. Step 3: Ensure the pump is correctly assembled and connected.
2. Step 4: Open the priming plug.
3. Step 5: Fill the pump casing and suction pipe with water from a suitable container until full.
4. Step 6: Close the priming plug securely.
5. Step 7: Remove the cover of the electrical terminal box.
6. Step 8: Ensure the cover is properly closed after electrical connections are made.

Diagrams illustrate filling the pump with water, closing the priming plug, and accessing/securing the electrical terminal box.

Electrical Connection

1. Step 9: Connect the power supply to the pump's terminal box according to local electrical codes and the wiring diagram provided. Ensure the correct voltage and frequency are used. The diagram shows connections for Live (L), Neutral (N), and Earth (G/Y) wires. A power switch (0/Off, 1/On) is depicted for controlling the pump.

Diagrams show the internal wiring of the terminal box, illustrating the connection of power cables (Live, Neutral, Earth) and the operation of the power switch.
