Setup
- Unpack: Carefully remove the thermometer from its packaging. Inspect for any visible damage.
- Placement: Place the thermometer directly into the pool or spa water. The thermometer is designed to float on the surface.
- Tethering (Optional): If desired, use the attached string to tether the thermometer to a fixed point, such as a ladder or pool edge, to prevent it from drifting away. Ensure the string is securely fastened.
- Stabilization: Allow the thermometer to remain in the water for at least 5 minutes to allow the internal mercury or alcohol column to stabilize and provide an accurate reading of the water temperature.
Operating Instructions
The Ocean Blue Deluxe Floating Thermometer operates passively by measuring the ambient water temperature. No batteries or external power sources are required.
- Reading Temperature: Observe the red line on the thermometer's scale. The top of the red line indicates the current water temperature.
- Scale Units: The thermometer displays temperature in both Fahrenheit (°F) and Celsius (°C). Read the value corresponding to your preferred unit.
- Optimal Viewing: For the most accurate reading, view the thermometer at eye level to avoid parallax error.
Maintenance
Regular maintenance will ensure the longevity and accuracy of your thermometer.
- Cleaning: Periodically wipe the thermometer's exterior with a soft, damp cloth to remove any dirt, algae, or mineral deposits. Do not use abrasive cleaners or solvents, as these may damage the plastic casing or the temperature scale.
- Storage: When not in use for extended periods, especially during off-season, clean the thermometer thoroughly and store it in a cool, dry place away from direct sunlight and extreme temperatures.
- Inspection: Regularly inspect the plastic casing and the string for any signs of wear, cracks, or damage. Replace the thermometer if significant damage is observed to ensure continued accuracy and safety.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Inaccurate Reading | Not enough time to stabilize; thermometer exposed to direct sunlight or air. | Allow at least 5 minutes in water for stabilization. Ensure thermometer is fully submerged in water (except for the floating cap) and not in direct sunlight for prolonged periods while reading. |
| Thermometer Sinks | Damage to the floating mechanism or water ingress. | Inspect the casing for cracks. If damaged, the thermometer may need replacement. |
| Scale is Unclear/Yellowed | Exposure to chemicals, UV light, or mineral deposits. | Clean with a soft cloth and mild soap. If yellowing persists due to age/UV exposure, replacement may be necessary for optimal readability. |
