Setup and Installation
The Gecko TSC-4 keypad is designed for integration with Gecko M-Class spa control systems. Installation typically involves connecting the keypad to the main control system via an 8-pin JST plug with a 10-foot cord. Due to the nature of spa electrical systems, professional installation by a qualified technician is highly recommended to ensure safety and proper functionality.
Installation Steps (General Guidance):
- Power Disconnection: Ensure all power to the spa control system is completely disconnected at the main breaker before beginning any installation work.
- Mounting: Securely mount the keypad in the desired location on the spa's topside, ensuring it is easily accessible and protected from direct water exposure.
- Cable Routing: Carefully route the 10-foot cable from the keypad to the spa control pack, avoiding kinks or damage to the cable.
- Connection: Locate the appropriate 8-pin JST receptacle on your Gecko M-Class control system. Align the 8-pin JST plug from the keypad with the receptacle and firmly insert it until it clicks into place.
- Sealing: Ensure any openings created for cable routing are properly sealed to prevent water ingress into the spa's internal components.
- Power Reconnection: Once all connections are secure and verified, restore power to the spa system.
Important: Refer to your specific Gecko M-Class control system manual for detailed wiring diagrams and safety precautions.
