It is essential that the End User be made aware of the O&M requirements related to the EAN ESP unit.

If the red LED indicator light switches on systematically between cleaning regimes the cleaning schedule should be

adjusted accordingly.

8.2.4

As soon as the red light illuminates, the unit cell needs to be cleaned. If the EAN ESP unit is not visible, AOM proposes

a remote indicator that can be installed in the kitchen and linked to the EAN units.

8.2.5

When cleaning the AOM equipment, do not use caustic chemical. The chemical could damage the aluminium ESP cell.

Troubleshooting

Note: All trouble shooting should be performed by qualified personel and extreme caution should be used when working on the

EAN ESP unit electrical boards.

Problem: The EAN ESP unit does not power ON (no green LED light/ no voltage)

Have the electrical connections including the fan

interlock been done as per AOM specifications?

If 240 V power reaches the unit, is the fuse continuity

on the PCD assured (red light on the PCB)?

Problem: The EAN ESP unit powers ON but the amperage fluctuates and does not settle to a fixed amount

Has the unit been properly cleaned and/or is the red

LED light showing on the door?

Have the cells been removed and replaced within the

unit?

Problem: The EAN ESP unit powers ON but the amperage fluctuates and does not settle to a fixed amount – an electrical

discharge can also be heard within the unit.

Have the cells been removed and replaced within the

unit?

Has a cell been damaged?

Problem: The EAN ESP unit powers ON but no amperage is shown on the amperemeter

Was this observed before or after the changeover of

electrostatic cells?

Check 240 V power reaches the unit when the fan is switched ON

If not, replace the fuse

If yes, the issue is with the PCB which is faulty and needs to be

replaced.

The EAN ESP unit needs to be cleaned as the buildup of grease and

other contaminants has affected the electrical connections of the

unit.

If yes, the connections between the EAN unit and the cell, as well as

between the cells need to be checked as follows:

‐ The EAN ESP unit insulators situated on the door are free from

grease

‐ The cells are equipped with the required springs and gaskets and

all the connections are ensured.

If yes, the cells need to be checked for any visible damage,

particularly in the case where aluminimum plates are bent and

touching.

If yes, attempt to fix any mechanical damage to the cells or replace

the cell with another clean cell.

If after, one of the cells has a fault. Remove the cells and review the

cells including checking that the the high voltage wires are all

attached.
