Jet System Selector Valve
All hot tubs (except the Aurora HP, Aurora XLT, Caliente HP, and Tria d II) are equ ipped with spa-side Selector
Valves, see Figure 1. These valves can be used to divert jet power from one area within the hot tub to another.
The valves are adjustable and can be used to suit the bather’s taste. The valves may offer some resistance to
operation when the hot tub pump is on. This is a normal condition, and is caused by the high rate of water flow
and pressure that travels through the valves.

Ultra Pure Water Management System
The Chairman II, Caliente HP, Diplomat, Chairman, Californian, Nautilus , Aurora II, Aurora XLT and Triad II are
equipped with a highly advanced hot tub water treatment method, the Ultra Pure Water Management System.
Ultra Pure is an integrated water management system with ozone injection, a contact chamber, 100% filtration, and
heating on demand.
CrystalZone Water Management System
Specifically engineered for Dimension One spas, the CrystalZone Water Management System found in the Arena,
Triad, Caliente, and optionally on the Aurora HP, provides an integrated ozone pur ification and filtration for hot
tubs. It maintains the pre-set hot tub temperature, witho u t the use of a jet pump. Using a Mazzei-T ozone injector,
the CrystalZone Water Management System provides cleaner water at lower operating costs. You’ll spend more
time enjoying your hot tub and less time maintaining it.
Vision Systems
Vision Cartridge, an alternative purification system, can be used in conjunction with your Ultra Pure or
CrystalZone Water Management Systems. 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 Water Care section for more information.
Heater and Circulation Pump Control
On all Dimension One Spas, when the water temperature is 1° F (0.55° C) below the set te mperature the heater
will turn on and remain on until the water temperature rises to 1° F (0.55° C) above the set temperature. To
prevent the hot tub from overheating, the circulation pump turns off when the water temperature rises 2° F (1.1°
C) above the set temperature. When the water temperature cools down to the set temperature, the circulation
pump will turn on.
The circulation pump will run for short periods when the water temperature is 2° F (1.1° C)
above set temperature to provide optimum operation. (The circulation pump is optional on the
Aurora HP.)
Note
Smart Heat (Available only on Dimension One Spas)
Smart Heat optimizes heat recovery using the amperage that you have available. Along with computerized load
sharing, that automatically recognizes the number of jet pumps in use, compares it with the available power, S mart
Heat recognizes the difference between the set temperature and the actual water temperature, and adjusts the
heater to optimize the heater output.
