Once a month (or as often as necessary) the cell should be removed and inspected for scale build-up or depris on the cell
blades. If the cell scales continuously, consult the Trouble shooting section in the manual.
1.
To prepare the system for servicing:
a.
Stop water flow to the Lectranator board by turning off the booster pump and/or the filter
pump. If applicable, shut off AC power to ORP/pH/CL controller and close the flow cell/probe loop valves so as
to isolate the ORP/pH/CL electrodes.
b.
Record all
models
Power Supply Feed Rate knob settings.
c.
turn all
models
Power Supply Feed Rate Knobs to zero(0).
d.
Wait for green cell lights (second light from the top) to go out on all
models
Power supplies.
e.
Close the influent and effulent valves on each leg of cells.
f.
Be certain to verify
that the flow lights (bottom light) on each
models
Power Supply are on (lit).
g.
Unplug DC Cell Cord from the cell(s) to be serviced.
h.
Remove the cell or cells from the piping system.
2.
To remove debris from cell(s):
a.
Flush depris from the cell blades using a garden hose.
3.
To remove scale and deposits:
a.
Mix four parts water with one part muriatic acid or, four parts of water with one part Tabex®
Grime Away®(4:1).
b.
Immerse the cell into the solution. The foaming action is the calcium carbonate being
removed from the cell. Allow cell to remain in the solution for one half hour (maximum).
c.
Remove the cell and flush throughly with fresh water. If scale deposits still remain, repeat
procedure using a fresh acid solution.
4.
Re-installation of the cell(s):
a.
Re-install the cell(s) and tighten unions
(hand tight only)
.
b.
Before fitting the DC plug back onto the cell, make sure the DC plug and cell posts are dry.
Push DC plug securely onto cell to prevent water damage.
c.
Always
double check your connections to ensure that all DC plugs are connected to their designated Cells.
(example: DC plug B2 is connected to corresponding Cell B2, DC plug C1 to Cell C1, etc.)
5.
Putting System Back into Operation:
a.
Open the influent and effluent valves on each leg of cells. If applicable, re-open the valves to the flow cell or
probe loop and turn AC power back on to the ORP/pH/CL controller.
b.
Turn on the system booster pump and/or the filter pump. Adjust flow to 25 US Gallons/min., if necessary. (At
this point,
all flow switch lights should be “off”
. If not, contact your Lectranator Service Representative.)
c.
Reset all the
models
Power Supply Feed Rate knobs to recorded settings.
NOTE: The flow switches located on each leg of cells are a safety feature of the system. If the
flow lights fail to illuminate(light) when influent and effulent valves are closed, immediatley
turn off power to the entire system, and contact your Lectranator Service Representive.
WARNING: Always add acid to the water. Do not add water to the acid. Wear ALL protective
gear required by local safety regulations.
NOTE:Do not use any sharp object (screwdriver,chisel etc.) to chip scale or depris from the
blades of the Cell. Only the spray from the garden hose nozzle should be used.
