Hood Maintenance
This section explains periodic maintenance procedures for the ventless hood system. Adhering of these procedures will
help to maintain the unit's continuing performance.
5.03.1
Monthly Hood Interlock Inspection (typically performed by User)
Hood contains various interlocks which ensure that the hood & fryer unit will shutdown if certain conditions exist which are
not consistent with safe and effective operation. The interlocks should be inspected and tested MONTHLY as described
below. Code authorities may require that operators record these actives in a permanent Maintenance & Service Log. If
problems are detected, contact GILES Technical Services or an authorized service provider.
1.
Door Interlock Test: Start hood. With hood running, unlatch and slightly lift the bottom lip of the filter access
cover. Confirm that hood powers OFF when cover is lifted and the fryer under the hood turns OFF, or cannot be
turned ON.
2.
Baffle Filter Test: Remove the baffle filter, replace filter cover, then turn ON hood power. Verify that the red
[FILTER MISSING] light turns ON and the [FRYER POWER] light is OFF. Confirm that the fryer under hood will not
turn ON. Reinstall the baffle filter. See Sections 4.02.2 & 4.02.3, Removal & Installation.
3.
Charcoal & HEPA Filter Test: Same procedure as #2 except performed for the charcoal filter. Reinstall filter. See
Sections 4.02.6, 4.02.7, Removal & Installation. Use same procedure to test HEPA filter, if equipped.
4.
E.A.C. Filter Test (N/A for HEPA Filter Version): Same procedure as #2 & #3 except remove the E.A.C. collector
cell, replace and latch filter cover. Turn ON hood power. Verify that the [WASH] light is ON, along with the
amber [FRYER POWER] light. Wait approx. two (2) minutes, a beeping tone alarm should begin sounding.
Shortly, the [FRYER POWER] light should turn OFF. Check to ensure that fryer under hood will not turn ON.
Reinstall the E.A.C. cell. See Section 4.02.4. & 4.02.5, Removal & Installation.
5.
Filter Clogged Test: Perform this test ONLY after installing new Charcoal Filter. Start hood normally and allow it
to run. Use cardboard or other material and completely block 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 and the [FRYER
POWER] light should turn OFF. Check to ensure that fryer under hood will not turn ON. Remove the obstruction;
the alarm should silence and the [FRYER POWER] light should turn ON again.
Should any of these tests fail to yield the described results, contact a factoryauthorized service company and have the
unit evaluated and repaired. Call GILES Services at 800.554.4537 for assistance in locating a service provider in your
area.
5.04
Fire Suppression System Maintenance
The selfcontained fire extinguishing system in the hood must be maintained in accordance with the Standard for Wet
Chemical Extinguishing Systems, NFPA 17A and with the instructions of the system installer.
All inspection, maintenance, troubleshooting, repairs and general servicing of the fire extinguishing system must be
performed by an authorized Ansul® Distributor/Dealer. Required maintenance activities are described in the subsequent
