4.2 Water Connections
The unit uses 1/2" NPT water connections. Ensure proper sealing to prevent leaks.
4.3 Mounting
The unit is designed for wall mounting. Securely fasten the heater to a sturdy surface using appropriate hardware (screws included). Ensure adequate space for ventilation and access for maintenance.
4.4 Application Guidance
The performance of the tankless water heater depends on the incoming water temperature and flow rate. Refer to the chart below to determine the approximate flow rate (GPM) for your area based on inlet water temperature, assuming an outlet temperature of 105°F.

5. Operating Instructions
5.1 Digital Display and Touch Screen
The unit features a one-piece glass panel with a digital LED display and touch controls. The display shows the incoming water temperature and the set heating temperature.
5.2 Temperature Adjustment
To adjust the desired water temperature, use the 'UP' and 'DOWN' touch buttons on the front panel. The adjustable temperature range is 82°F to 131°F (30°C to 55°C). The unit will automatically heat water to the set temperature as it flows through.
- Power On/Off: Press the 'ON/OFF' button to activate or deactivate the unit.
- Increase Temperature: Press the 'UP' button.
- Decrease Temperature: Press the 'DOWN' button.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your water heater.
- Cleaning: Wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Scale Buildup: While the design minimizes scale, in areas with hard water, periodic inspection and descaling by a qualified professional may be necessary.
- Water Inlet Filter: Check and clean the water inlet filter periodically to ensure unrestricted water flow.
- Professional Inspection: It is recommended to have the unit inspected by a qualified technician annually.
7. Troubleshooting
If you experience issues with your Kweetle KT-24 water heater, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water / Unit not turning on | No power; Circuit breaker tripped; Water flow too low. | Check power supply; Reset circuit breaker; Ensure adequate water flow (minimum 0.5 GPM). |
| Water not hot enough | Temperature setting too low; Incoming water temperature too cold; Excessive flow rate. | Increase temperature setting; Reduce water flow; Refer to application guidance chart. |
| Leakage detected | Loose connections; Damaged seals. | Tighten water connections; Inspect and replace seals if necessary (contact qualified professional). |
| Error code on display | Internal malfunction; Sensor issue. | Note the error code and consult a qualified technician. Disconnect power before inspection. |
If the problem persists after attempting these solutions, contact a qualified technician for assistance.
