Operation & Filter Maintenance

4.03.3

E.A.C. Filter Status & Alarm

Two LED indicator light clusters on the control panel show the operational status of the

electronic air cleaner (EAC)

system

on each side of the hood.

[ON]

Indicates that the EAC collector cell is
installed, powered and operating.
When system is operating normally,
this is the

only

light ON.

[WASH]

This light turns ON to indicate:

• Filter cell is not installed or is mis

aligned.

   • Collection fins contain an excessive amount of captured grease residue.
   • There is poor connection between the filter cell contact plate & the hood contacts.
   • Too many ionizer wires on cell are broken or missing.
   When

[WASH]

light is ON, an alarm condition exists and air cleaning has stopped. After approximately

two (2) minutes, a beeping tone alarm will begin to sound and shortly thereafter, power to the cooking
appliances under the hood is shutdown.

IMPORTANT!

[WASH]

light is

NOT

intented to be a signal for routine cleaning of the cells,

DO NOT USE

AS SUCH

. Typically, the collection cells must be cleaned

DAILY

to ensure optimum air cleaning

performance. See

Section 4.04.2, EAC Filter Cell Cleaning

[CHECK]

This light turns ON to indicate:

   • An ionizer wire is broken & shorting out against the cell frame.
   • Cell is damaged & has shorted out to ground.
   • Collection fins are shorted because of excessive moisture.
When

[CHECK]

light is ON

system is no longer operating to clean the air, even though the hood continues

to run and the cooking appliances are still receiving power.

DO NOT CONTINUE TO OPERATE HOOD

WHEN THIS CONDITION EXIST, DAMAGE TO SYSTEM CAN OCCUR ... DETERMINE THE CAUSE AND
CORRECT!

NOTE: If no LED

lights turn ON

when hood is started, the EAC power supply may be faulty ... call for service

The following actions may clear an EAC alarm condition:

1. Turn OFF hood

POWER

switch.

2. Remove the EAC collector cells and clean as described in

Section 4.04.2

3. Inspect cells for broken & missing ionizer wires, bent fins, or other damage. Ionizer wires are replaceable

(specify 20” when ordering replacements)

. Bent fins may be straightened gently by hand so that no fin is

touching an adjacent one. A cell with excessive damage (broken or badly bent frame, broken insulators, etc)
must be replaced.

4. Inspect cells for moisture on fins ... if present, allow cell to dry thoroughly before reinstalling.

5. Inspect the EAC contact plates inside hood compartment. Clean grease accumulation away with a mild

degreasing cleaner and dry thoroughly.

6. Replace collector cells

(

Section 4.02.7

)

and restart hood

(Section 4.01)

. If the condition persist, contact a

qualified service agent.
