Hood Cleaning & Maintenance

The following section describes the activities generally needed to maintain and clean the OVH-10/11-FB Hood.

Attention to these procedures will help ensure that the Hood remains in good condition and continues to run

efficiently and safely.

A Maintenance & Service Log is provided in this manual to help track these activities, see Table 5.03.

The Hood features various interlock devices to ensure that the unit is shutdown in the event that conditions arise that

are not consistent with safe and effective operation. These interlocks should be tested MONTHLY as described below.

Use the Maintenance & Service Log and check the box that corresponds to each functional test. If a problem is

found, contact an authorized service provider.

Door Interlock Check: Turn power switch ON. With Hood running, remove the Filter Access Door, as

described in Section 4-02.2. Confirm that the Hood does shutdown when door is removed, and that the

under-hood appliance cannot be operated.

Baffle Filter Check: Place power switch in the OFF position; remove the Baffle Filter, see Section, 4-02.2.

Replace Access Door and turn ON power. The red Baffle or Charcoal Filter Missing light should illuminate

and the Appliance Powered light should be OFF. Confirm that the under-hood appliance cannot operated.

Turn power OFF and reinstall the Baffle Filter.

EAC Filter Check: Place power switch in the OFF position; remove the EAC Filter Cell, see Section 4-02.2.

Replace Access Door and turn ON power. All three EAC status lights should illuminate and after

approximately 2 minutes, an intermittent tone (beeping) alarm should sound. The Appliance Powered light

should turn OFF. Confirm that the under-hood appliance cannot operated. Turn power switch OFF and

reinstall EAC Filter Cell.

Charcoal Filter Check: Place power switch in the OFF position; remove the Charcoal Filter, see Section 4-

02.2. Replace Access Door and turn ON power. The red Baffle or Charcoal Filter Missing light should

illuminate and the Appliance Powered light should be OFF. Confirm that the under-hood appliance cannot

operated. Turn power OFF and reinstall the Charcoal Filter.

Filter Clogged Check: Perform this check ONLY after installing a new Charcoal Filter. The easiest method

for checking the clogged filter interlock is to completely block the Hood exhaust outlet with piece of

cardboard while the hood is running and the appliance power is ON. A continuous tone alarm should sound

when the exhaust is blocked, the red Baffle or Charcoal Filter Clogged light should illuminate and the

Appliance Powered light should turn OFF. The appliance should also turn OFF during this time. Remove the

obstruction; the alarm should silence and power should be restored to the appliance. If the alarm tone does

not sound, fails to silence, or the appliance fails to turn OFF or turn ON, contact a service agent to have the

Clogged Filter interlock checked.
