2. Información importante de seguridade
AVISO: Improper installation, adjustment, alteration, service, or maintenance can cause property damage, injury, or death. Read all instructions thoroughly before installation or use. This appliance must be installed by a qualified professional (electrician and plumber) in accordance with all local electrical and plumbing codes.
- Seguridade eléctrica: The unit requires a dedicated 120V/30A circuit. A customer review highlighted a potential discrepancy regarding wiring. For a 3.5kW 120V unit, a 30A breaker typically requires 10 AWG wire. If a 40A breaker is used, 8 AWG wire is necessary. Ensure the electrical connection is a 120V circuit with one hot, one neutral, and one ground wire. Consult a qualified electrician to verify correct wiring and breaker sizing for your specific installation to prevent fire hazards and ensure safe operation.
- Presión da auga: Ensure water pressure is within the recommended range for optimal performance and to prevent damage.
- Prevención de fugas: Regularly inspect for leaks. The unit features built-in leak detection.
- Protección contra sobrecalentamento: The unit includes overheating protection to prevent scalding.
- Isolated Systems: Fully isolated water and electrical systems enhance safety.
- Rango de temperatura: The adjustable temperature range is 80°F–113°F. Do not exceed recommended temperatures.
