2. Safety Instructions

Always adhere to the following safety guidelines to prevent injury or damage to the pump.

• Electrical Safety: Ensure the power supply matches the pump's voltage (115 Volts). Do not operate the pump with a damaged power cord or plug. Always connect to a grounded outlet. Do not immerse the power plug or cord in water.
• Water Temperature: Do not pump water exceeding 95°F (35°C).
