This guide provides essential information for the installation and maintenance of the Bestway Hydrium Oval Pool. Key requirements include a flat, level surface, 2-3 people for assembly, and an ambient temperature above 15ºC (59ºF) for easier liner handling. The pool should be filled to 90% capacity (up to the welding line).
Safety Information
Read and follow all instructions.
- Continuous, active, and vigilant supervision of weak swimmers and non-swimmers by a competent adult is required at all times.
- Designate a competent adult to supervise the pool each time it is being used.
- Never dive into any shallow body of water.
- Do not use the swimming pool when using alcohol or medication.
- Keep rescue equipment (e.g., a ring buoy) and a working phone with emergency numbers near the pool.
- Do not leave the drained pool outside, as it is liable to deformation due to wind.
Setup Instructions
Choosing the Correct Location:





- The surface must be flat, smooth, and capable of supporting the total weight of the water and users.
- Position the pool away from objects children could use to climb into the pool.
- Ensure the side with the water inlet and outlet is facing the power source for the filtration system.
- Avoid surfaces like mud, sand, gravel, or balconies.
Assembly:
- Compare parts in the box to the parts list.
- Install the ladder (if included) before starting the pool installation.
- Place the Ground Cloth in the selected area.
- Follow the step-by-step illustrations for assembling the steel wall, PVC rails, and connectors.
- Important: During steel wall installation, lift and place it inside the PVC rails without applying vertical pressure to avoid deformation.
Filling the Pool
- Fill the pool with tap water until it reaches the welding line (90% capacity).
- Do not overfill, as this could cause the pool to collapse.
- When 90% full, check that the distance between the water surface and the top of the rails is consistent all around. If not, the surface is not level.
Maintenance
Water Maintenance:
- Use pool chemicals (chlorine or bromine tablets) with a chemical dispenser or floater. Do not throw chemicals directly into the water.
- Maintain water chemistry within the specified parameters (e.g., pH 6.8 to 7.6, Free active chlorine 0.3 to 1.5 mg/l).
- Use a pool skimmer and vacuum cleaner regularly to remove dirt.
Winterization & Storage

- Ensure the water level is at least 10 cm (3.9") lower than the pool inlet A before winter.
- Place an inflatable item (like a pool pillow) on the water surface to support the pool cover.
- For storage, ensure the liner is completely clean and dry. Sprinkle with talcum powder to prevent sticking. Store in a dry place between 15ºC and 38ºC.

Common problems
Leave the liner in the sun for one hour to make it more pliable.
Ensure the surface is perfectly flat and level. Do not apply vertical pressure during wall installation.
Check valves and seams when the pool is 90% full. Use the provided underwater adhesive repair patch for leaks.
Before use
- Ensure the surface is flat, smooth, and capable of supporting the total weight.
- Check for overhead power lines or underground pipes.
- Verify all parts are present according to the manual.
- Have 2-3 people available for assembly.
- Prepare a pool ladder (if not included).
Specs in practice
- Ambient Temperature
- Assemble when the temperature is above 15ºC (59ºF) for easier liner handling.
Images and diagrams
- Diagrams show the step-by-step assembly of the steel wall, PVC rails, and skimmer installation.
- Specific diagrams illustrate the correct water level and winterization steps.
Model compatibility
- If a pump or ladder is included, refer to their specific manuals.
- The ladder must match the pool size.
