1. Introduction
This manual provides essential information for the safe and efficient operation, installation, and maintenance of your TRIUMPHKEY Instant Water Heater, Model A1. Please read this manual thoroughly before installation and use, and retain it for future reference.
2. Safety Information
Your TRIUMPHKEY Instant Water Heater is equipped with multiple safety protection devices. Adherence to the following safety guidelines is crucial for preventing accidents and ensuring long-term performance:
- Gas Pipe Inspection: Regularly check the air pipe (soft hose) for signs of aging or cracks. Use a detergent solution to check for air leaks at the joints. If leaks are detected or the pipe is damaged, replace it immediately.
- Water Pipe Inspection: Periodically inspect the water heater pipes for any leaks.
- Combustion Monitoring: Pay attention to any abnormal combustion patterns. If unusual operation is observed, discontinue use and consult a qualified technician.
- Cleaning: Use only neutral detergents to clean the surface of the water heater. Avoid strong solvents, thinners, or benzine, as these can damage the appliance finish and components.
- Overheat Protection: The unit features overheat protection. If activated, the solenoid valve will automatically cut off the gas supply.
- Overpressure Protection: In case of excessive water pressure, the system will discharge water through the bypass of the drain valve to prevent damage.

5. Operating Instructions
The TRIUMPHKEY Instant Water Heater operates automatically, providing hot water on demand.
Basic Operation:
- Power On: Ensure batteries are correctly installed in the battery box for ignition.
- Water Flow: Open a hot water tap. The water pressure will activate the gas valve, and the burner will ignite automatically, providing hot water.
- Water Flow Off: Close the hot water tap. The gas supply will automatically cut off.
Temperature and Flow Adjustment:
- Gas Control: Use the 'Gas Control' knob (Min/Max) to adjust the intensity of the flame, influencing the maximum temperature.
- Water Control: Use the 'Water Control' knob (Low/High) to adjust the water flow rate. A lower flow rate generally results in hotter water, while a higher flow rate results in cooler water.
- Seasonal Mode: Select 'Winter' or 'Summer' mode to optimize heating performance based on the incoming water temperature.
The machine can operate normally with a water pressure of 0.02 MPa (for high temperature settings) or 0.03 MPa (for low temperature settings).

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your water heater.
- Air Pipe (Soft Hose) Check: Frequently inspect the air pipe for any signs of wear, cracks, or damage. Replace immediately if necessary.
- Leak Detection: Periodically check all gas and water connections for leaks. Use a soapy water solution on gas connections; if bubbles appear, there is a leak.
- Cleaning: Clean the exterior surface of the water heater with a soft cloth and a neutral detergent. Do not use abrasive cleaners, strong solvents, or harsh chemicals.
- Professional Inspection: It is recommended to have the unit inspected by a qualified technician annually.
7. Troubleshooting
This section addresses common issues you might encounter with your water heater.
- No Hot Water / Burner Not Igniting:
Possible Cause: Water pressure is too low.
Solution: The gas valve is opened by water pressure. Ensure adequate water pressure. If water pressure is consistently low, the burner may not ignite. - Hot Water Temperature Decreases with Multiple Outlets:
Possible Cause: Exceeding the water heater's maximum output capacity.
Solution: The water heater has an upper output limit. When multiple water outlets are opened simultaneously, the total demand may exceed this limit, causing a temperature drop. Reduce the number of active hot water outlets. - Hot Water Appears White/Cloudy:
Possible Cause: Air in the water heating up and rising pressure.
Solution: This is a normal phenomenon. The hot water will become transparent after a short period as the air dissipates.
