- Heater Connection: The heat.wav heater is integrated. Ensure proper water flow through the heater before powering on the system.
- Pump Connections: Connect Pump 1 (1-speed or 2-speed) to the P1 connector. If applicable, connect Pump 2 (2-speed) to the P2 connector.
- Blower Connection: Connect the 1-speed blower to its designated connector.
- Other Accessories: Connect circulation pump, ozone generator, or AV receptacles to the appropriate connectors as per your spa configuration.
- Keypad Connection: Connect your compatible Gecko keypad (e.g., in.k600, in.k450, in.k200, K-85) to the main keypad connector.
- Bonding: Ensure the system is properly bonded to the spa structure and other metallic components as required by local codes.
Operating Instructions
The Gecko in.xe system operates in conjunction with a compatible keypad. Refer to your keypad's specific user manual for detailed navigation and function controls. General operations include:
- Power On/Off: Use the main power switch to turn the system on or off.
- Temperature Adjustment: Set your desired water temperature using the keypad controls.
- Pump Activation: Activate Pump 1 and Pump 2 (if installed) for jets or circulation.
- Blower Activation: Turn the blower on or off for air jets.
- Light Control: Operate the spa lights through the keypad.
- Mode Selection: Select different operating modes (e.g., Standard, Economy, Sleep) to manage heating cycles and energy consumption.
Note: The specific functions and their access methods will vary depending on the model of your Gecko keypad.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your control system.
- Power Disconnection: Always disconnect power to the spa before performing any maintenance or inspection.
- Visual Inspection: Periodically inspect the control system for any signs of damage, corrosion, or loose connections.
- Fuse Check: If a component fails to operate, check the corresponding fuse inside the control box. Replace blown fuses with the exact same type and rating. Refer to Image 2 for fuse locations.
- Enclosure Integrity: Ensure the control system enclosure remains sealed and free from moisture ingress.
- Water Quality: Maintain proper spa water chemistry to prevent scale buildup in the heater and other components.
Troubleshooting
This section provides solutions to common issues. For complex problems, contact a qualified service technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| System does not power on. | No power supply, tripped GFCI, blown main fuse. | Check main power breaker and GFCI. Inspect and replace main fuse if blown (ensure correct rating). |
| Pump/Blower not working. | Blown component fuse, loose connection, motor issue. | Check the specific fuse for the pump/blower. Ensure connections are secure. If fuse is good, motor may require service. |
| Heater not heating. | Low water flow, air lock, heater element failure, thermostat issue. | Ensure pumps are running and water flow is adequate. Bleed air from the system. If problem persists, professional service is required. |
| Keypad not responding. | Loose keypad cable, keypad malfunction. | Check keypad cable connection to the control system. If still unresponsive, the keypad may need replacement. |
