Hood Cleaning & Maintenance
5. Hood Cleaning & Maintenance
This section describes the steps to generally maintain and clean FSH‐6 Hoods. Attention to these procedures will
help ensure the Hood remains in satisfactory operating condition and continues to run efficiently and safely.
A Maintenance & Service Log is provided, see Section 5.04.
5.01 Monthly Hood Interlock Inspection (Can be Performed by User)
The hood design incorporates various interlock switches to ensure that the unit will shutdown when conditions exist
that are not consistent with safe and effective operation. The interlocks should be tested MONTHLY as described
below. Use the Maintenance & Service Log to record completion of the test. If problems are detected, contact
GILES or an authorized service provider. NOTE: Anytime a filter access door is opened and closed, the hood must be
restarted with the power switch (press & momentarily hold the top of switch).
1. Door Interlock Test: Start hood. With hood running, unlatch and slightly open each access door, one at a
time. With each side confirm that hood powers OFF when opened and appliances under the hood cannot be
turned ON.
2. Baffle Filter Test: Remove the baffle filter from one side, then start hood. Verify that the red [FILTER
MISSING] light turns ON. Check to ensure that appliances under hood will not turn ON. Replace filter and
repeat test on the other side. See Sections 4.02.2 & 4.02.3, Removal & Installation.
3. Pre‐Filter/Charcoal Filter Test: Same procedure as #2 except perform for each pre‐filter and charcoal filter,
one at a time in succession. Reinstall the filters. See Sections 4.02.4, 4.02.5, 4.02.8 & 4.02.9, Removal &
Installation.
3. E.A.C. Filter Test: Remove one of the EAC collector cells, close and latch door, then start hood. Verify that
[WASH] light on EAC Status comes ON for the side without cell. Wait approx. two (2) minutes. A beeping
alarm should begin sounding. After a few seconds, check to ensure that appliances under hood cannot be
turned ON. Turn off hood, reinstall cell, and repeat for other side. See Section 4.02.6. & 4.02.7, Removal &
Installation.
5. Filter Clogged Test: Perform this test ONLY after installing new prefilters & charcoal filters. Start hood
normally and allow to run. Use cardboard, or other suitable material, to completely block the hood exhaust
outlet, holding it firmly in place so that no air is escaping. Within a few seconds, a continuous tone alarm
should begin sounding. Check to ensure that appliances under hood cannot be turned ON. Remove the
obstruction; the alarm should silence and you should be able to turn ON appliances again.
Should any of these tests fail to give the described results, contact a factory‐authorized service company and have
the unit evaluated and repaired. A Giles Manufacturer's Representative can provide information about nearby
authorized service providers, or call GILES Services at 800‐554‐4537 for assistance.
