Important notes when using Hailea rechargeable air pumps for koi ponds:
Choose an air pump that matches the pond size, number of pumps, and outlet size to ensure efficient operation and extend its lifespan.
Plug into the correct standard power source to avoid short circuits, fires, and explosions.
The pump is designed to be placed above water level with air outlets pointing below the water surface.
If placed below water level, a one-way valve is required to prevent water from flowing back into the pump when the power is off.
If the pump falls into the water, disconnect the power before removing it from the pond. Let it dry for 2-3 days and carefully inspect it before reconnecting.
Disconnect the power when cleaning the pond or performing any underwater operations.
Run a full discharge cycle every 3-4 months to prevent battery degradation.
