Circulation Pump Operation
Your system is equipped with a circulation pump. The circulation pump provides
24-hour continuous water circulation and filtration. The circulation pump turns
over the entire spa water capacity at a minimum of 5-9 times every hour
(depending on water capacity). It works like this: a dedicated, energy efficient
circulation pump constantly draws water from the spa, runs it through the filter
and the heater (heating only when necessary), then back to the spa. The ozone
output is on whenever the circulation pump is running except when the jet
pump(s) or blower is (are) activated by the user. The ozone generator will turn off
for one (1) hour any time a function button (Jets 1, Jets 2 or Aux.) is pressed.
The Circulation pump will turn off for 30 minutes at a time when the water
temperature reaches 3F (1.5C) above the set temperature (most likely this will
happen in a very hot climate or during summer).
Heater Operation
Your spa is equipped with an electrical heater. By setting your thermostat to the
desired temperature, your heater will automatically turn on and off as needed.
The temperature set point (set temperature) can be adjusted from 80F to
104F/26C-40C. To raise the set temperature press the "Warm Arrow Up"
button. To lower the set temperature, press the "Cool Arrow Down" button. The
start up temperature is set at 100F/37.5C. The last measured temperature is
constantly displayed on the LCD. In Economy mode the heater heats the spa
water only during filter cycles. In sleep mode the heater heats the spa water to
within 20F (11C) of set temperature only during filter cycles.
Filter Cycle Programming - Optional
As explained above in a 24-hour circulation pump system the filtration cycle
program operates only on a limited basis. At the start of each filter cycle the
blower (if equipped) will run for 30 seconds; and the pump 1 (low) and, if
equipped, pump 2 (high) will run for five minutes to prevent the spa water from
becoming stagnant in the plumbing and air lines and improve skimming action.
In addition, the programmable filtration cycle (start/end) times of each cycle will
designate the start and end time where the heater is allowed to operate in
economy and sleep modes. The default filter cycles are as follows:
The first filter cycle is automatically activated at 8 a.m. and operates the pump
until 10 a.m. The filter indicator icon will light when filter 1 cycle is running.
The second filter cycle is automatically activated at 8 p.m. and operates the
pump until 10 p.m.. The filter indicator icon will light when filter 2 cycle is running.
Time of day settings are not preserved in the event of power loss; time will have
to reprogrammed upon each power up.
Spa settings (temperature set point, filter cycles) are preserved.
