- Ensure the T-Joints are properly aligned and secured. These joints are engineered for high strength and infused with UV inhibitor for weather resistance.
- The frame is constructed from galvanized steel with inner and outer powder coating for ultimate rust resistance.
4.3 Liner Installation
- Carefully unfold the pool liner onto the ground cloth, ensuring the drain plug is positioned correctly.
- Attach the liner to the assembled frame according to the detailed instructions provided in the separate assembly guide.
4.4 Filling the Pool
Begin filling the pool with water. As the water level rises, smooth out any wrinkles in the bottom of the liner. Stop filling when the water reaches the recommended fill line.
5. Operation
The Intex Ultra XTR Deluxe pool set includes a Krystal Clear Sand Filter Pump SX2800 for efficient water filtration.
5.1 Krystal Clear Sand Filter Pump SX2800

The sand filter pump provides excellent water filtration and features a 6-function control valve. Sand in the filter can last up to 5 years with regular backwashing. The pump flow rate is 2800 GPH.
- Filter: Normal filtering operation.
- Backwash: Cleans the sand filter by reversing water flow.
- Rinse: Used after backwashing to settle the sand.
- Recirculate: Circulates water without filtering (e.g., for chemical mixing).
- Drain: Drains water from the pool.
- Close System: Shuts off all flow to the filter.
Refer to the separate Krystal Clear Sand Filter Pump manual for detailed instructions on installation, operation, and maintenance of the pump.
5.2 Hydro Aeration Technology

6. Maintenance
Regular maintenance is crucial for the longevity and hygiene of your pool.
6.1 Water Chemistry
Maintain proper water chemistry by regularly testing and adjusting pH, chlorine, and alkalinity levels. Consult a pool supply professional for recommended chemical levels and treatment procedures.
6.2 Filter Maintenance
Perform regular backwashing and rinsing of the sand filter as indicated by pressure gauge readings or recommended schedule. Replace filter sand every 3-5 years, or as needed.
6.3 Cleaning
- Skim debris from the water surface daily.
- Brush pool walls and floor weekly to prevent algae growth.
- Vacuum the pool floor as needed to remove settled debris.
6.4 Liner Repair
In case of minor damage, a repair patch is included for easy fixes. Clean and dry the affected area thoroughly before applying the patch according to its instructions.
6.5 Winterization
For seasonal use, properly winterize your pool before freezing temperatures arrive. This typically involves draining the pool, cleaning the liner, disassembling components, and storing them in a dry, protected area. Refer to the full manual for detailed winterization steps.
