4. Setup and Installation

Installation of the in.k450 keypad requires careful attention to detail and may involve modifying the existing spa shell. Professional installation is highly recommended.

Installation Steps:

1. Disconnect Power: Ensure all power to the spa system is completely shut off at the main breaker before beginning.
2. Remove Old Keypad (if applicable): Carefully detach the old keypad from its mounting. Note the existing wiring configuration.
3. Prepare Mounting Hole: The in.k450 keypad may require a specific cutout size. If replacing an older model like the k400, a significant modification to the existing opening may be necessary to accommodate the new keypad's dimensions (approximately 6 9/16" x 2 5/16" for the cutout). Use appropriate tools to create a clean and precise opening.
4. Apply Gasket: Ensure the adhesive gasket is properly seated around the keypad's perimeter to create a watertight seal.
5. Insert Keypad: Carefully insert the new in.k450 keypad into the prepared opening.
6. Secure Keypad: From underneath, secure the keypad using the provided wing nuts onto the threaded studs. Do not overtighten.
7. Connect Cable: Route the 10-foot in.link cable to the spa pack and securely connect it to the designated port.
8. Restore Power: Once installation is complete and all connections are secure, restore power to the spa system.
