Using It on the Job

1. Power Isolation: Always start by isolating power to the evaporative cooler at the main switchboard. Verify zero voltage with a multimeter before touching any wiring.
2. Old Controller Removal: Carefully unmount the old controller. Document the wiring configuration, either by taking a clear photo or drawing a simple diagram, before disconnecting wires.
3. New Controller Connection: Connect the new Coolbreeze CBSP3220 controller's wiring to your system, strictly following the manufacturer's wiring diagram and your documentation from the previous step.
4. Mounting: Securely mount the new wall controller to the wall, ensuring all connections are snug and protected.
5. System Test: Restore power to the unit. Test all functions of the controller – fan speeds, pump operation, mode selection, and timer settings – to confirm correct installation.

Limitations & Safety Notes

• Installation involves electrical work. This should only be performed by a licenced electrician or competent person adhering to AS/NZS wiring rules and local regulations.
• Ensure the specific Coolbreeze model and its control board (MRU or ECRU) are compatible with this CBSP3220 controller before purchase.
• Always verify power isolation and lockout procedures before commencing any work on electrical components.
• Refer to your Coolbreeze unit's service manual for specific wiring diagrams and troubleshooting steps.

Tradie Pro Tip: Before you unhook the old controller, always snap a clear photo of the wiring connections. It's a lifesaver when you're hooking up the new one, especially if the original installer didn't label anything clearly.
