removed from the ESP Cells and the Cells removed.

Standard Safety Voltage Test – Cont.
Cell Rotation Procedure
1.
Once the Standard Safety Voltage Test has been conducted and there is no voltage, the Cells can be
safely removed.
2.
Remove the spare Cells from the soak tank and drain the water. It may be necessary to hose the tank
interior to remove grease and smoke residue.
3.
Remove the three (3) wires from the outer Cell by pulling forward from the Cell terminals. Route the
wires up onto the Wire Hook at the top of the compartment and down the left side into the holding
channel to keep out of the way while removing the Cells (Refer to Figure
4-18-1)
.
4.
Pull all the Cells straight out slowly.
CAUTION: Each Cell weighs 53 lbs. and may be awkward to handle, particularly Cells in the
upper racks rows #3 and #4. It is highly recommended that a heavy duty steel wheeled ladder
be used in removing the upper Cells. Extreme care must be taken to avoid damaging the Cell. Do
not grip or push on the Cell plates or the ionizer wires.
5.
After the row of Cells has been removed, replace
them with clean Cells taken from the soak tank.
Caution - Be sure to replace the Cells with the airflow pointing in the same direction of airflow as
marked on the front of the Cell access door. Also be sure to install the Inner Cells first, the Cells
with the springs.
