Using It on the Job

  1. Isolate Power: Always ensure power to the evaporative cooler is completely isolated at the mains and locked out before starting any work.

  2. Disconnect Old Unit: Carefully disconnect the existing control box, making clear notes or taking photos of all cable connections to avoid mix-ups.

  3. Mount New Control Box: Install the new TEK7EC control box securely in the same location as the old unit.

  4. Connect Cables: Reconnect the Tek400 or Tytronics control cables to the new TEK7EC, double-checking each connection for security and correctness.

  5. Test Functionality: Restore power and thoroughly test all fan speeds and functions to ensure smooth modulation and proper system operation.

Limitations & Safety Notes

  • Always isolate power before attempting any electrical work to prevent injury.
  • Ensure correct cable compatibility and connections for safe and effective operation.
  • This control box is only compatible with the listed Tekelek components and specific older cooler models.
  • Follow the manufacturer's installation guidelines and local electrical safety standards.

Tradie Pro Tip

Before pulling out the old control box, snap a quick photo of the wiring connections. It'll save you a heap of guesswork when hooking up the new TEK7EC, especially on those tight rooftop installs.
