4. Installation
Proper installation is critical for the safe and efficient operation of your water heater. It is highly recommended that installation be performed by a qualified professional.
4.1 Pre-Installation Checklist
- Verify that the installation location is suitable for the unit's dimensions (16.2"W x 17.5"H x 12.65"D) and weight (19.3 pounds when empty, significantly more when full).
- Ensure a dedicated 120V electrical outlet is available within reach of the appliance line cord.
- Confirm that water supply lines (hot and cold) are accessible.
- Have necessary plumbing fittings and tools on hand. Note that the unit has 1/2" NPT connections, and adapters may be required for existing 3/8" lines.
4.2 Mounting the Unit
- Select a secure, vertical wall mounting location capable of supporting the full weight of the water heater.
- Use appropriate mounting hardware (not included) for your wall type.
- Ensure the unit is level and securely fastened.
4.3 Plumbing Connections
- Turn off the main water supply.
- Connect the cold water supply line to the inlet on the water heater (typically marked blue or 'C').
- Connect the hot water outlet from the water heater (typically marked red or 'H') to the hot water faucet line.
- Install the provided Pressure Relief Valve (PRV) into the designated port on the unit. Route the PRV discharge line to an open drain, ensuring it is not blocked or capped.
- Open the main water supply and check all connections for leaks. Allow the tank to fill completely and purge air from the system by opening a hot water faucet until water flows steadily.
4.4 Electrical Connection
- Ensure the unit is properly filled with water before connecting to power.
- Plug the appliance line cord into a grounded 120V electrical outlet.
5. Operation
Once installed and powered, the EcoSmart ECO MINI 4 is designed for straightforward operation.
5.1 Initial Startup
- After plumbing and electrical connections are complete and the tank is full of water, plug in the unit.
- The 'POWER' indicator light will illuminate, indicating the unit is receiving electricity.
- The 'HEATING' indicator light will illuminate when the unit is actively heating water. This light will turn off once the set temperature is reached.
5.2 Temperature Adjustment
- The unit features a temperature control knob on the front panel.
- Rotate the knob clockwise to increase the water temperature and counter-clockwise to decrease it.
- Allow time for the water to heat up after adjusting the setting. The heating time will vary based on the initial water temperature and the desired setting.
6. Maintenance
Regular maintenance helps ensure the longevity and efficient performance of your water heater.
- Pressure Relief Valve (PRV) Test: Annually, lift and release the lever on the PRV to ensure it operates freely and is not obstructed. Water should discharge from the drain line. If no water discharges, or if the valve sticks, replace it immediately.
- Drain and Flush: Periodically (e.g., annually), drain and flush the tank to remove sediment buildup. This involves disconnecting power, closing the cold water inlet, connecting a hose to the drain valve, and opening the drain valve.
- Exterior Cleaning: Clean the exterior of the unit with a damp cloth. Do not use abrasive cleaners or solvents.
