Compu Pool CPSC Series Manual 17
9.3.4 Add Salt. The Compu Pool CPSC Series will automatically let you know if the
salinity concentration has fallen below acceptable levels. When illuminated for
more than two hours, add more salt as needed. The amount required varies with
pool size. Refer to Table 1 to determine additional amount of salt needed.
9.3.5 Over Salt. When illuminated, the salt content is more than sufficient. The CPSC
Series has a built-in regulating system that enables it to continue to produce
chlorine with the increased salt content. At this point do not add any further salt
and allow the salt content to return to desirable levels.
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 the section entitled “Water Chemistry” 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 build up 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. The clear housing of the cell allows easy visual inspections, and with correct
water chemistry, the cell will only need cleaning once or twice a season (about
every 6 months).
10.3 Removing the Cell for Cleaning
10.3.1 Turn off all power and close return line valves, if applicable.
10.3.2 Remove the Blue UV covers.
10.3.3 Remove the collar nut from the cell head, releasing the clear cap that houses the
cell lead connections.
10.3.4 Disconnect the three cell lead connections from the cell terminal posts.
10.3.5 Pull entire cell away from the cell housing.
10.4 Cleaning the Cell
10.4.1 With the cell removed use a high pressure hose nozzle to spray off as much loose
scale and debris as possible. Use a plastic or wooden tool to remove deposits off
the plates.
