2000 Owner’s Manual
being ozonated and returned to the spa. During the process, the Silver
(Ag) residual is put into the water, which acts as a bactericide. When
used in the Ultra Pure or CrystalZone Water Management Systems,
Vision provides a natural, residual bactericide which compliments the
ozone oxidizing power. After excessive bather loads, however, an addi-
tional oxidizer may be required to remove accumulated organic com-
pounds. Be sure to carefully follow the included instructions for proper
use - DO NOT follow the standard water chemistry start-up procedures
contained in this manual and do not use a metal sequesterant in combi-
nation with Vision or add any Vision product to your spa within 72
hours of the addition of a metal sequesterant.
WARNING: While Vision is a bactericide which can be safely used as
an alternative for conventional halogens, it is not a “chemical free” sys-
tem. In order to gain the maximum benefits of Vision products, follow
the manufacturer’s directions. All other aspects and adjustments of
water chemistry such as pH and total alkalinity must adhere to the man-
ufacturer’s instructions relative to that specific product. As Dimension
One Spas has no control over the water source used in any spa applica-
tion, it will not be responsible for any staining below the water line and
any such occurrence will not be covered under any of its warranties.
HEATER AND CIRCULATION PUMP CONTROL
On all Dimension One Spas, when the water temperature is 1˚ below the
set temperature the heater will turn on and remain on until the water
temperature rises to 1˚ above the set temperature. On models that do
not have circulation pumps (Aurora HP, Interlude, Arena, and Triad
without the CrystalZone Water Management System) the low speed
pump will turn on during the heating cycle.
On models with Ultra Pure (Chairman II, Chairman, Diplomat,
Californian, Nautilus, Aurora II and Triad II) and models with the
Crystal Zone Water Management System: To prevent the spa from over-
heating, the circulation pump turns off when the water temperature rises
2˚ above the set temperature. When the water temperature cools down
to the set temperature, the circulation pump will turn on.
NOTE: The circulation pump will run for short periods when the water
temperature is 2˚ above set temperature to provide optimum operation.
