9.0 Automatic Filtration

Your spa is equipped with a small circulation pump which provides 24-hour
water filtration and maintains the water temperature efficiently and econom-
ically. The circulation pump draws water through the stage 2 MicroClean
filter cartridge (Section 1 1.1, Page 26), The only time the circulation pump
will stop is if the actual water temperature exceeds the programmed set
temperature by 1°C, a condition known as "summer logic." When this
occurs, the circulation pump remains off until the actual water temperature
cools to the set temperature. Refer to the summer logic definition below
for a thorough explanation of this feature.
Summer Logic: In warm weather, the water temperature in the hot tub may
exceed the set temperature. This condition may occur due to heat transfer-
ence from jets pump #1 and 24-hour circulation pump. If the water tem-
perature is higher than 35°C and rises 1°C above the set temperature, a
"Summer Logic" condition occurs that deactivates the circulation pump and
ozonator (if equipped). This safety feature cannot be altered! The cir-
culation pump and ozonator will remain off until the water temperature
cools to the set temperature (except between12AM-2AM when the circula-
tion pumps runs for it's mandatory 2-hour "clean-up" cycle when in summer
logic). To help prevent a "Summer Logic" condition, it may be necessary to
reduce filter cycle run time in warm weather.

9.1 Preset Filter Cycle

Your hot tub comes with one one-hour filter cycle already programmed
with a start time at 12:00 PM (noon). You can easily change the start
time, or the cycle length to suit your needs by following the steps outline
in section 10.2 (Page 24).

9.2 Clean-Up Cycle

The clean-up cycle is once per day in both Standard and Economy mode
at 12:00 PM (noon) for two minutes. This is not user programmable. Pump
#2 and blower activate for one minute to circulate any water in the
