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.
