Operating Instructions
Filling the Pool
- Before filling, ensure all drain plugs are securely closed.
- Begin filling the pool with water. As the water level rises, gently smooth out any wrinkles in the bottom of the liner, working from the center outwards.
- Fill the pool to the recommended fill line, typically indicated on the liner or in the separate pump manual. The pool has a capacity of approximately 10,874 liters.
Filter Pump Operation
The included filter pump is essential for maintaining water clarity. Refer to the separate filter pump manual for detailed setup and operation instructions.
- Connect the filter pump hoses to the pool's inlet and outlet fittings.
- Ensure the pump is placed on a stable, level surface away from the pool.
- Plug the pump into a grounded electrical outlet with a Residual Current Device (RCD).
- Operate the pump for several hours daily to circulate and filter the water.
