Cell cleaning:
In.clear™ includes a self-cleaning feature to prevent scale deposits
on the graphite electrodes of the in.clear™ system. However,
deposits may still form due to hard water. If that happens the cell
should be cleaned in an acidic solution.
To clean the in.clear
™
cell, follow these steps:
All power must be disconnected before any service
procedure is performed. Disconnect the
communication cable and power cable of the
in.clear™ unit.
Refer to acid manufacturer's instructions.
Wear eye protection and rubber gloves during these
operations. Splashing or spilling acid can cause severe
personal injuries and/or property damage.
Always work in a well-ventilated area.
Always add acid to the water, never add water to the acid.
Do not pour acid outside of the unit where
the connectors are located.
Never use Acetic acid to clean the cell, as this will cause
permanent damage to cell components and void the
warranty.
• To remove scales from the cell, we recommend to use
Phosphoric acid (non-diluted) as the preferred cleaning product.
• Close the spa Flow Shut Off Valves. Unscrew both unions
from the unit and remove the cell from the spa equipment
compartment.
Phosphoric acid
or muriatic acid
• Install the rubber washer and the plastic nut on the threaded end
of the cell. Tighten plastic nut firmly.
• Place the cell vertically with the cap end down into a plastic 19
liters (5 U.S. gallon) bucket and carefully pour the acid solution
into the cell until the 4 plates are covered (careful not to
overflow). The acid solution will begin to produce bubbles to
clean the electrodes.
A foaming action will follow, which is caused by the scale
deposits being dissolved from the plates. If rigorous foaming
action does not begin, the cell does not need to be cleaned.
Rinse and reinstall the cell.
• Allow the electrodes to remain in the solution until the foaming
has stopped. However, DO NOT leave in acid for more than
fifteen minutes. Excessive acid cleaning will damage the
electrolytic cell.
• Pour the acid solution back into the bucket and rinse the cell
thoroughly with clean tap water. If deposits are still visible, repeat
operation for fifteen minutes maximum (some acid may need to
be added to the solution).
• Remove the plastic nut and washer from the cell and keep them
for future cell cleaning.
• Rinse the in.clear™ with fresh water.
• Re-install the in.clear™ unit into spa system plumbing, tighten all
connections by hand. Open the spa flow Shut Off Valves.
• Reconnect the keypad and power cable.
• Turn power on and start up the pump. Check the keypad to
see that the bromine generation LED is on and resume normal
operation.
