6. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your water heater. It is highly recommended that installation be performed by a qualified electrician and plumber.
Installation Steps:
- Choose Location: Select a suitable wall location near the water supply and electrical outlet, ensuring it is protected from freezing temperatures.
- Mark Drilling Points: Hold the water heater against the wall at the desired mounting height and mark the screw locations.
- Drill Holes: Use an electric drill to create holes at the marked points.
- Insert Wall Plugs: Insert the provided wall plugs into the drilled holes.
- Mount Water Heater: Align the water heater with the wall plugs and secure it using the provided screws.
- Connect Water Inlet: Connect the cold water supply line to the inlet at the bottom of the water heater. Ensure a tight, leak-free connection.
- Connect Water Outlet: Connect the hot water output line to the outlet at the top of the water heater. Ensure a tight, leak-free connection.
- Connect Faucet/Shower: Connect the hot water output line to your faucet or shower head.
- Flush System: Before plugging in, open the hot water faucet and allow water to flow through the unit for a few minutes to purge any air from the system. This prevents dry burning.
- Plug In: Once the system is flushed and all connections are secure and leak-free, plug the water heater into a dedicated 110V electrical outlet.

9. Troubleshooting
If you encounter issues with your water heater, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water / Unit not turning on | No power, circuit breaker tripped, water supply off. | Check power connection, reset circuit breaker, ensure water supply is open. |
| Water not hot enough | Temperature setting too low, high water flow rate, cold incoming water temperature. | Increase temperature setting, reduce water flow, allow more time for heating if incoming water is very cold. |
| Error Code E2 displayed | Heating element issue or internal fault. | Turn off power, wait a few minutes, then restart. If the error persists, contact customer support. |
| Water leakage | Loose connections, damaged seals. | Immediately turn off water supply and power. Inspect and tighten connections. If damage is found, contact customer support. |
