10.0 MAINTENANCE
10.1 Water Chemistry
10.1.1 It is recommended that a pool water sample be taken to a Pool Professional once
per month for analysis. Please refer to Water Chemistry (section 5.0) for additional
information.
10.2 Electrolytic Cell
10.2.1 The cell operates most efficiently when it is clean. As a natural result of the
electrolytic process which creates chlorine from salt molecules, calcium is attracted
to the titanium plates in the cell. The self-cleaning feature helps to inhibit such build
up and scaling. However, the attraction of calcium and other minerals is inevitable
and eventually it must be removed. The cell only needs cleaning to ensure that
build up does not cause individual plates to come in contact with each other.
10.2.2 The clear housing of the cell allows easy visual inspections, and with correct water
chemistry, the cell will only need cleaning approximately every 3-6 months. In
regions with hard water (high calcium levels), more frequent cleaning may be
required.
10.3 Cleaning the Cell
10.3.1 Turn off power to the Power Module and pump.
10.3.2 Remove the Cell from the Cell Housing by loosening the Cell Collar on top of the
Cell Housing and pulling out. If required disconnect the Cell Cable wires at the
junction box underneath the Power Module (these must be reassembled firmly and
tightly).
10.3.3 With the Cell removed use a high pressure hose nozzle to spray off as much loose
scale and debris as possible.
