11.3.5 If further cleaning is required the cell needs to be cleaned in a mixture of one (1)
part Hydrochloric (Muriatic) Acid into five (5) parts water (always add acid to the
water).
11.3.6 WARNING: When using the acid ensure to use rubber gloves and appropriate eye
protection.
11.3.7 Mix the acid and water in a suitable container and place the cell into the container .
Cell cleaning tubes are available from Compu Pool as an additional accessory.
Ensure that the acid solution fill line is below the Cell Head area, submersion of this
area will damage the cells electronics and void the warranty.
11.3.8 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.
11.3.9 Note: Excessive cleaning will reduce the lifespan of the cell.
11.4 Cleaning the Cell with the Acid Wash System
11.4.1 Follow the instructions provided with the Acid Wash System to carry out this
procedure.
11.5 Replacing the Cell
11.5.1 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.
11.6 Removing the Cell for Replacement or Cleaning
11.6.1 Turn off the power to the unit. Disconnect the nuts clamping the cell leads to the
cell heads with the appropriate sized wrench / socket (24mm).
11.6.2 Turn valves M1 and M2 to the closed position.
11.6.3 Unscrew the air bleed bolt at the top of the cell head. The air bleed bolt should only
be removed and re-assembled by hand. Over tightening the bolt will crack the cell
head.
11.6.4 Unscrew the cell head collar.
11.6.5 With a large flat bladed screwdriver carefully leverage the cell out of the housing
enough so that it can be lifted out by hand. Carefully remove the cell.
11.6.6 Insert the new cell in the reverse manner. Check that the Cell Head o-rings are in
good condition and apply a suitable o-ring lubricant if they are dry. Ensure that the
cell head collar is screwed down tightly and that the nuts clamping the cell leads to
the cell head are tight (see 8.5.7).
