Using It on the Job

1. Before starting any work, always ensure the evaporative cooler's main power supply is isolated and locked out to prevent accidental startup.
2. Access the motor and fan assembly, taking note of the existing belt routing and how the old pulley is secured.
3. Loosen any fasteners, remove the fan belt, and then carefully detach the worn or damaged pulley.
4. Install the new 90mm pulley, re-attach the belt, and adjust the tension. Proper belt tension is critical for smooth, wobble-free operation and to prevent premature wear on components.
5. Double-check all connections and ensure no tools or loose parts are left inside the unit before restoring power and testing.

Limitations & Safety Notes

• Always isolate the evaporative cooler's power supply before attempting any service or repair.
• Ensure correct belt tensioning to avoid excessive load on the motor or potential fan bearing damage.
• This pulley is only for use on compatible Braemar and Breezair units as specified.
• Follow all manufacturer's guidelines for installation and maintenance procedures.

Tradie Pro Tip

When swapping out a pulley, it's a smart move to inspect the fan belt and motor bearings too. A new pulley on a worn belt or dodgy bearing won't last long, and you'll be back on site sooner than you'd like. Save yourself a callback.
