Operating Instructions
Intelligent Temperature Control System
The HIRALIY Heated Water Hose is equipped with a smart temperature sensor that automatically manages the heating process to prevent freezing and conserve energy.
- Heating Activation: The heating element automatically turns on when the ambient temperature drops below 5°C (41°F).
- Heating Deactivation: The heating element automatically turns off when the ambient temperature rises above 10°C (50°F).
- Accuracy: The temperature sensor operates with an accuracy of ±2°C.

Control Unit Indicators
The control unit features indicator lights and a reset button:
- Power Indicator (Red): Always on when the unit is plugged into a power source, indicating power supply.
- Working Indicator Light (Green): Illuminates green when the heating element is active (temperature below 5°C/41°F). It turns off when heating is not required (temperature above 10°C/50°F).
- Overload Reset Button: Press this button to reset the unit if an overload or leakage protection is triggered.

Maintenance and Storage
- Cleaning: Clean the exterior of the hose with a damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the electrical components are dry before plugging in.
- Inspection: Regularly inspect the hose for cuts, abrasions, or kinks. Check the electrical cord and plug for any signs of damage.
- Storage: When not in use, disconnect the hose from both water and power sources. Drain all water from the hose. Coil the hose loosely and store it in a dry, protected area away from direct sunlight and extreme temperatures. Avoid storing with sharp objects that could puncture the hose.
- Fittings: Periodically check the brass fittings for corrosion or wear. Replace rubber washers if they appear cracked or worn to maintain a leakproof seal.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power indicator light (red) | No power to the outlet; faulty outlet; damaged power cord. | Check the power outlet with another device. Ensure the plug is fully inserted. Inspect the power cord for damage. |
| Hose not heating (green light off in cold) | Temperature above 10°C (50°F); temperature sensor malfunction; internal heating element issue. | Verify ambient temperature is below 5°C (41°F). If cold and green light is off, press the overload reset button. If problem persists, contact customer support. |
| Water flow is restricted or frozen | Hose kinked; extreme cold exceeding hose capabilities; insufficient insulation at connections. | Straighten any kinks in the hose. Ensure connections are properly insulated. Verify the hose is powered and heating. |
| Water leaks at connections | Loose connection; worn or missing rubber washer; damaged fitting. | Tighten connections. Check and replace rubber washers if necessary. Inspect fittings for damage. |
| Overload reset button tripped | Electrical overload; short circuit; leakage. | Unplug the hose, wait a few minutes, then press the reset button and plug it back in. If it trips repeatedly, discontinue use and contact customer support. |
