Installation and Engineering Notes

• Confirm the borehole depth, diameter and water level before installation.
• Calculate the total dynamic head rather than relying only on borehole depth.
• Install the pump fully submerged and above the borehole bottom.
• Use a strong safety rope or stainless-steel suspension cable.
• Connect the pump through a compatible DC solar pump controller.
• Use 3 × 550W solar panels installed in an unshaded position.
• Select the correct solar-cable and delivery-pipe sizes.
• Install dry-run protection where possible.
• Fit a non-return valve where required.
• Macire can provide technical guidance on correct system sizing.

Care, Maintenance and Operations

• Clean the solar panels regularly.
• Check pump cables and controller connections periodically.
• Prevent the pump from running without water.
• Inspect the delivery pipe for leaks or restrictions.
• Protect all electrical connections from moisture.
• Monitor the controller for fault indications.
• Avoid pumping water with excessive sand or sediment.
• Use compatible spares and technical support available through Macire.

Performance Guidance

The stated 5m³/h or 5,000L/h is the maximum flow capacity. Actual output varies with pumping head, sunlight, pipework and borehole conditions.

Mini FAQ

1. What is the maximum water output?

The pump can deliver up to 5m³/h, equivalent to 5,000 litres per hour, under suitable operating conditions.

2. What is the maximum pumping head?

The pump has a maximum head rating of 120 metres.

3. How many solar panels are recommended?
