NORDIC HOT TUBS | OWNER’S MANUAL |
25
STEP 5: FILTRATION
Your new spa will require a certain amount ltration
time to keep the water clean and sparkling. The factory
default setting is F2 which means your hot tub will lter (2)
continuous hours, twice a day. If you change the setting to
F4, it will lter (4) continuous hours at a time twice a day.
You may need more than this depending on the bather load
and frequency of use. Your dealer or authorized service
representative will be able to give you recommendations
based on your anticipated use.
The default start time is the time you power-up your spa
with the breaker. The rst ltration cycle will begin within
a few minutes of power-up. The 2nd lter cycle will begin
12 hours later. You can use this power-up timing to control
when your hot tub runs. This is useful for avoiding on-peak
electric charges or avoiding ltering during the heat of
the afternoon in warmer climates. (this helps stabilize the
temperature)
NOTE: Please reference the topside control instructions
earlier in this manual for further instructions on setting the
lter cycles.
Additional Note: Your dealer or authorized service
representative will be your best resource for water
chemistry-related questions that you may have. They will be
happy to answer any questions that you may have.
