compupool products CPSC Series - Maintenance (Continued); Cell Cleaning Procedure

Compu Pool CPSC Series Manual 18
10.4.2 Do not use any sharp or metallic objects to remove scale. Scraping or scratching
the cell plate's edge or surface will allow chemical attack of the plate, cause
premature failure of the cell and will void the warranty.
10.4.3 If further cleaning is required the cell needs to be cleaned in a mixture of one (1)
part Hydrochloric (Muriatic) Acid into four (4) parts water (always add acid to the
water). When using the acid ensure to use rubber gloves and appropriate eye
protection.
10.4.4 Mix the acid and water in a bucket and place the cell into the bucket. Ensure that
the acid fill line is below the cell head area, submerging of this area will damage the
cells electronics and void the warranty.
10.4.5 Clean the cell until the foaming action stops (typically 5 to 10 minutes). Rinse the
cell with fresh water and re-install into the plumbing line.
10.4.6 Note: Excessive cleaning will reduce the lifespan of the cell.
10.5 Winterizing the Cell
10.5.1 The Electrolytic Cell will be damaged by freezing water just as your pool plumbing
would. In areas which experience severe or extended periods of freezing
temperatures, be sure to drain all water from the pump, filter, supply and return
lines before any freezing conditions occur. The Power Unit is capable of
withstanding any winter weather and does not need to be removed.
10.6 Replacing the Cell
10.6.1 When the titanium blades inside the Electrolytic Cell have reached the end of their
lifespan, replacements are available so that the whole system does not have to be
removed. Replacements are easily switched out. To ensure quality and value, only
genuine Compu Pool replacement parts may be used.
10.7 Removing the Cell for Replacement
10.7.1 Turn all AC power off.
10.7.2 Remove the Blue UV covers.
10.7.3 Remove the collar nut from the cell head, releasing the clear cap that houses the
cell lead connections.
10.7.4 Disconnect the three cell lead connections from the cell terminal posts.
10.7.5 Remove the cell from the clear housing.
