chemistry such as pH and total alkalinity  must adhere to the manufactur-
er’s instructions relative to that specific product.  As  Dimension One
Spas has no control over the water  source used in any spa application, 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 tem-
perature rises to 1˚ above the set  temperature.  On models that do not
have circulation pumps (Interlude, Arena, Triad and Quadra without the
CrystalZone Water Management System) the low speed pump will turn
on during the heating cycle.  
On models with Ultra Pure (Chairman, Diplomat,  Californian, Nautilus,
Aurora II and Aurora I) and models with the  Crystal Zone Water
Management System:  To prevent the spa from overheating, the circula-
tion pump turns off when the water  temperature rises 2˚ above the set
temperature.  When the water temperature cools down  to the set tempera-
ture, 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.
