Cleaner Adjustments
Warning – Risk of Injury
Turn the Booster Pump and Filtration Pump OFF
before making adjustments to the cleaner. Always
make adjustments outside of the pool. Failure to do
so may cause injury.
Changing Spin-Out Frequency
• In most pools it will not be necessary to change the
Spin-Out frequency.
• Viio comes with a 3-prong Spin-Out cam installed,
which causes the cleaner to Spin-Out once every 50
seconds. This is appropriate for most pools.
• Pools that are small, shallow in depth and/or have
many sharp geometric features or other obstacles
may benefit from more frequent Spin-Outs. For such
pools, open the Cam Cap and replace the 3-prong
cam with the 5-prong 30-second cam.
• Pools that are very large and/or have very few
obstacles may benefit from less frequent Spin-Outs*.
For such pools, open the Cam Cap and replace the 3-
prong cam with the 2-prong 75-second cam.
• The goal is to maximize cleaning time and minimize
the amount of time backing-up and spinning out.
- If Viio is spending too much time at an obstacle
waiting for a Spin-Out, use a cam with more prongs
for more frequent Spin-Outs.
- If Viio rarely needs to back-up and Spin-Out near an
obstacle then a cam with fewer prongs and less
frequent Spin-Outs will increase effective cleaning
time.
Changing Spin-Out Cam
1.
Turn the Cam Cap to open.
2.
Turn the Thumbscrew counter-clockwise and
remove it from the square stem.
3.
Remove the Spin-Out Cam.
4.
Place the desired Cam in place over the Stem.
5.
Screw the Thumbscrew into the stem.
6.
Close the Cam Cap.
Adjusting Spin-Out Duration
Each Cam has a “Summer” side and a “Winter” side (see
Sun & Snowflake logos on each Cam). The Summer side
is usually preferred. If the pool water is cold (below 60
degrees F), the Pressure Hose becomes stiffer and may
prevent the Cleaner from Spinning-Out enough to escape
from obstacles. The “Winter” Cam side will provide longer
Spin-Outs so the Cleaner operates better in cold water.
1. Turn the Cam Cap to open.
2. Turn the Thumbscrew counter-clockwise and
remove it from the square stem.
3. Remove the Cam, turn it over and replace the Cam
so the desired (Sun or Snowflake) side is face-up.
4. Replace the Thumbscrew into the square stem.
5. Close the Cam Cap.
