In some situations, if Suction Vacuum is too strong for the Pool Cleaner to perform, a Ballast leveling adapter is required to avoid AIR TRAPPED inside the Whirlpool.
All SkimmerMotion sold after September 2013 will be shipped with the Ballast.
In september 2014 we change the design of the Ballast, the effect is the same and the change was due manufacturing factors.
If your SkimmerMotion was bough BEFORE September 2013, just contact us to a free upgrade.
The ballast should be located 2 segment (aprox 2 ft), below the SkimmerMotion (Pool surfase).
