Setup and Installation
Warning: Installation should only be performed by a qualified electrician or plumber in accordance with all local and national electrical and plumbing codes. Ensure power is disconnected before beginning installation.
- Choose Location: Select a suitable wall-mounted location, ensuring it is protected from freezing temperatures and has adequate space for connections and maintenance. The unit is designed for bottom water inlet.
- Mounting: Securely mount the water heater to the wall using the provided accessories. Ensure the mounting surface can support the weight of the unit when filled with water.
- Plumbing Connections: Connect the cold water inlet (blue port) and hot water outlet (red port) to your plumbing system. Ensure all connections are tight and leak-free. The water inlet is equipped with a filter screen to reduce impurities.
- Electrical Connections: Connect the unit to a dedicated 220V AC power supply. Ensure the wire requirements (≥ 4 mm² Copper Core Wire) and air switch requirements (≥29A) are met. Install a grounding electrode and a leakage protection device (not included) as per safety instructions.
- Fill with Water: Before powering on, open a hot water faucet to allow water to flow through the heater and purge all air from the system. Once water flows steadily from the faucet, close it.
- Power On: Restore power to the unit.
