Bonaire 1/2" Solenoid Valve with Dump

This Bonaire 1/2" water solenoid with a dump/bleed function is a crucial spare part for maintaining your evaporative cooler's water management system. It's built to provide reliable on/off control of the water supply, ensuring your unit runs smoothly, especially during those long, hot Aussie summers.

A dodgy solenoid can lead to constant water flow, leaks, or even a dry cooler, so having a solid replacement ready makes a big difference for ongoing maintenance.

Best For

• Replacement in Bonaire evaporative cooling units.
• General evaporative cooler service and maintenance.
• Preventing water wastage due to continuous overflow.

Compatibility

This 24V solenoid valve is designed specifically for Bonaire evaporative cooling systems, featuring 1/2" BSP Male inlet and 1/2" BSP Female outlet threads. It replaces Bonaire Part Number 6051636SP.

If you're running a different model, check fittings and specs before ordering.

Features

Using It on the Job

1. Isolate Power: Always disconnect power to the evaporative cooler at the mains switch before starting any work.
2. Shut Off Water: Close the main water supply valve to the cooler.
3. Drain System: Allow the cooler's reservoir to drain completely.
4. Remove Old Solenoid: Carefully unthread the old solenoid, minding any residual water. Disconnect the 24V wiring.
5. Install New Solenoid: Apply appropriate thread sealant to the male BSP inlet thread. Screw the new solenoid into place, ensuring it's oriented correctly (often an arrow indicates flow direction). Reconnect the 24V wiring.
6. Restore and Test: Slowly open the water supply and check for leaks. Restore power and test the cooler's operation, ensuring the dump function works as expected.

Limitations & Safety Notes

• Always ensure power and water are isolated before installation or service.
• Only use this solenoid with water within the specified pressure range.
• Ensure correct voltage (24V) is supplied to prevent damage to the coil.
• Use proper thread sealant on all connections to prevent leaks.
• This part is designed for Bonaire evaporative coolers; compatibility with other brands is not guaranteed.

Tradie Pro Tip

Before you even start tightening, always make sure your threads are clean and you've applied a quality thread sealant. A small leak on a solenoid can turn into a big headache later, especially with the cooler sitting up on a roof. Double-check for drips when you first turn the water back on.

Pair With

When replacing a solenoid, it's often a good time to check your Bonaire float valve and filter pads. These components work together in the evaporative cooler's water system, and replacing them together can prevent future issues.
