Brand: Haier

Model: PJF2-300

Type: Operating

This manual is also suitable for

PJF2-200

Haier PJF2-300 solar water heater utilizes solar energy to heat water efficiently. With a 300-liter storage capacity, it provides ample hot water for various household needs. The advanced solar collector captures sunlight and transfers heat to the water circulating within the system. It features automatic temperature control, ensuring a consistent supply of hot water. The safety considerations outlined in the manual emphasize the importance of proper installation and handling to prevent potential hazards.
