Three Pre-Checks
- Wiring: storage models up to 2200W fit a 10A socket; instant models need a 16A dedicated line.
- Outlet direction: bottom outlet for under-sunk connections, top for wall pipes — not interchangeable.
- Space: measure clear height/depth/width, keep 5cm around the unit.
Five Universal Steps
- Shut off water and power.
- Mount the unit: drill-and-hang, stand on an anti-slip pad, or screw to the cabinet side panel.
- Plumb: add a tee on the cold valve, wrap tape 8-10 turns, connect inlet (blue) and outlet to the faucet cold pipe.
- Fill and bleed until water runs steady without bubbles.
- Power on: outlet water at 40°C+ after 20 minutes, no leaks, cool socket.
