UltraPure™ Water Management System

This spa is equipped with a highly advanced hot tub water treatment method, the UltraPure™ Water Management System. The UltraPure™ Water Management System is an integrated water management system with ozone injection, dual contact chambers, and 24-hour filtration.

Energy conversation is designed into the UltraPure™ Water Management System. The circulation pump has a built-in heat recovery system that diverts circulation pump heat directly to the spa water. This feature reduces demand on the spa heater, and saves energy.

To prevent the hot tub from overheating, the circulation pump turns off when the water temperature rises 1.1° C (≅2° F) above the set temperature. When the water temperature cools down to the set temperature, the circulation pump will turn back on.

The circulation pump will run for short periods when the water temperature is 1.1° C (≅2° F) above set temperature to verify temperature.

Vision

Vision, an alternative purification system, can be used in conjunction with your UltraPure™ Water Management System. The advantage of Vision over conventional halogens (bromine and chlorine) is that it will, as a result of lower chemical use, provide softer-feeling water. Additionally, low chemical levels can mean fewer dissolved solids, which results in less water chemistry maintenance. Please refer to the Vision instructions for proper installation. Also read the Water Care Guide for more information.

Smart Heat

On all Dimension One Spas, when the water temperature is at least 0.55° C (≅1° F) below the set temperature the heater will turn on and remain on until the water temperature rises to 0.55° C (≅1° F) above the set temperature. Smart Heat recognizes the difference between the set temperature and the actual water temperature, then determines the rate of heating required to best maintain the set temperature.

Load Sharing

Load Sharing recognizes the number of jet pumps in use and compares it with the available power. Computerized load sharing adjusts the heater to maximize the heater output based on heat requirements and spa operation, then optimizes heat recovery using the amperage that you have available.
