Can I install this water heater myself?
While the unit is designed for wall-mounting, professional installation is strongly recommended due to the high electrical and plumbing requirements. Incorrect installation may void the warranty.

How do I clean and maintain the water heater?
Regularly wipe the exterior with a soft damp cloth. Do not use abrasive cleaners. Check the inlet filter occasionally and clean if clogged. For internal descaling, consult the manual.
What should I do if the water heater does not heat?
First, ensure the unit is receiving power and the breaker is on. Check if the water flow is sufficient (minimum 1 L/min). If the problem persists, the heating element may need replacement. Contact customer support.
Can I use the water heater for a whole house?
The EVT-9K is suitable for a single point-of-use (e.g., a sink or shower). For whole-house applications, consider a higher power unit or multiple units.
