6. Installation
This section outlines the steps for installing your Ranein Mini Tank Electric Water Heater. For safety and proper function, it is highly recommended that installation be performed by a qualified professional.
6.1 General Installation Guidelines
- Choose a location that is protected from freezing temperatures and is close to the point of use to minimize heat loss.
- Ensure adequate clearance around the unit for maintenance and air circulation. Refer to the 'Please Confirm Your Under-sink Space' image for minimum clearances if installing under a sink.
- The unit can be mounted on a wall, placed on the floor, or on a shelf.

6.2 Water Connection
- Turn off the main water supply.
- Apply Teflon tape to the threads of the pressure relief valve (T/P valve) and install it into the hot water outlet (red marked port) on top of the water heater. Tighten with a wrench.
- Connect the flexible water hoses to the hot water outlet (from T/P valve) and cold water inlet (blue marked port) on the water heater. Ensure connections are tight to prevent leaks.
- Connect the other ends of the flexible hoses to your hot and cold water lines. The hot water line from the heater connects to the hot water faucet, and the cold water line from the main supply connects to the cold water inlet of the heater.
- Attach the drain hose to the T/P valve's discharge port. Route the drain hose to an open drain or suitable discharge area.
- Slowly turn on the main water supply and check for leaks. Open a hot water faucet to allow air to escape from the tank until water flows steadily.

- Inspect T/P Valve: Annually check the pressure relief valve for proper operation. Lift and release the lever on the valve to ensure it opens and closes freely.
- Anode Rod Inspection: The magnesium anode rod helps protect the tank from corrosion. It should be inspected and replaced as needed, typically every 1-3 years depending on water quality. This procedure may require professional assistance.
- Exterior Cleaning: Clean the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
9. Troubleshooting
If you encounter issues with your water heater, refer to the following common troubleshooting steps. For complex problems, contact customer support.
