2. Safety Information

Read all safety instructions before installing or operating this water heater. Failure to follow these instructions can result in property damage, personal injury, or death.

• Electrical Connection: This appliance requires a dedicated electrical circuit and must be wired into your home’s electrical system. It is not a plug-in appliance. Installation must be performed by a qualified electrician in accordance with all local and national electrical codes.
• Water Temperature: Hot water can cause severe burns. Exercise caution when setting water temperature. Consult the operating instructions for safe temperature settings.
• Pressure Relief Valve: Do not block or tamper with the temperature and pressure relief (T&P) valve. This valve is a critical safety device designed to release pressure in the event of excessive temperature or pressure.
• Ventilation: Ensure adequate clearance around the unit for proper airflow, especially for the heat pump components. If ducting exhaust air, follow all instructions for proper installation.
• Leak Detection: Regularly inspect the area around the water heater for any signs of water leaks. Address leaks immediately to prevent water damage.

3. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your Rheem Hybrid Heat Pump Water Heater. It is highly recommended that installation be performed by a qualified professional.

3.1 Pre-Installation Checks

• Location: Select a location that provides sufficient space for the unit (26"W x 66"H) and allows for proper airflow around the heat pump. Ensure the floor can support the weight of the unit (178 lbs dry, significantly more when full).
• Electrical Requirements: Verify that a dedicated 240-volt electrical circuit with appropriate amperage is available.
• Water Connections: The unit features new top water connections and side universal water connections for flexible plumbing.
• Wi-Fi Signal: Before final placement, use a phone or tablet to check the Wi-Fi signal strength in the intended installation area to ensure optimal EcoNet connectivity.

3.2 Installation Steps (Summary)

1. Positioning: Place the water heater on a level surface.
2. Plumbing: Connect the cold water inlet and hot water outlet lines. Install the temperature and pressure relief (T&P) valve and route its discharge pipe according to local codes.
3. Electrical Wiring: Connect the unit to the dedicated electrical circuit at the easily accessible electrical junction box.
4. Ducting (Optional): If desired, duct the colder exhaust air from the heat pump into an attic, another room, or outside your home using the duct-ready design.
5. Fill Tank: Slowly fill the tank with water before turning on the power. Open a hot water faucet in your home to allow air to escape.
6. Power On: Once the tank is full and all connections are secure, restore power to the unit.

5. Maintenance

Regular maintenance ensures the longevity and efficient operation of your water heater.
