-Unpacking and Inspection of Hood
1. Upon receiving of hood, carefully inspect hood for damage. If visible damage is noted upon
unpacking, this should be indicated on shipping bill in the event that a damage claim is required
to be filed.
2. Carefully remove unit packaging to prevent damage to hood.
3. Remove hood grease filters and hood grease cup and store in a safe location until after hood is
installed.
-Installation of Hood (See Figure 1)
Note: Hood installation should be done in accordance latest requirements of NFPA-96, Removal
of Smoke and Grease-Laden Vapors from Commercial Cooking Equipment.
1. Notice location of hanger brackets on top of hood. Assure that building structure has been
prepared to allow for hanger rods at each required hanger bracket location. Hood hanger
brackets are provided for 1/2” threaded rods.
2. Carefully locate hood into position on floor underneath where it will be suspended. For hood
model EC-RS (hood with rear supply plenum), refer to step 3 below.
3. For hood model EC-RS, hang rear supply plenum at wall prior to installation of hood. Hang
plenum using hanger rods at top and securing bottom to wall using sheet metal screws. Locate
lower edge of rear plenum at a point of 32” above finished floor (This is based on a 24” high hood
mounted at 78” above finished floor).
4. Lift hood up using hi-jack device. Keep hood level during this process. Locate lower front edge
of hood at height that will be at a point of 78” above finished floor (verify this dimension with any
existing building plans that may be available).
5. Attach hanger rods with rod couplings to structure above and to each hood hanger bracket
coupling.
6. After all hanger rods are securely in place, lower hi-jack stands from underneath hood and
remove.
7. Level and plumb hood by adjusting hanger rod couplings as necessary.
8. For hood model EC-FP or EC-FR, hang front supply plenum at ceiling in front of hood. Use 1/2”
threaded rods as described above for hood.
9. Any additional sealants required after installation of hood will be based on local code
requirements and local AHJ (Zero Clearance models once installed, require joint between wall
and hood to be sealed with fire rated caulking or other approved methods by the local AHJ).
-Duct Connections (See Figure 2)
1. Connect exhaust ductwork (and supply ductwork if applicable) to duct collar(s) located on top
of hood.
2. Exhaust duct should be continuously welded to collar(s) at top of hood.
3. Supply duct should be attached to hood collar(s) using sheet metal screws. Note: If supply
duct collar includes fire damper, access should be provided to fire damper. Be sure supply
balancing damper is completely open and that sheet metal screws used do not interfere with
opening and closing of balancing damper.
-Electrical Connections
Note: Any electrical work done on unit should be performed only by a licensed electrician. All
wiring should be done in accordance with the National Electric Code.
1. Locate hood electrical wiring diagram located on top of hood.
2. If hood is provided with optional control switch panel, make field wiring connections to electrical
junction box as indicated on wiring diagram for operation of hood light switch and/or hood fan
switches.
3. If hood is provided with optional Motor Control Center unit, make field wiring connections to
unit as indicated on the provided electrical wiring diagram.

-Start-up of Hood
1. After all power connections are completed and with hood light and fans switches in ‘Off’
position, turn on power at breaker.
2. Re-install hood grease filters and grease containers in hood.
3. Turn on hood light switch to ensure that hood lights are operating correctly.
4. Turn on fans switch to ensure that fans are operating correctly. (This should only be performed
after hood fans are completely installed and wired per the fan instructions).
-Hood Airflow Ratings
1. Hood System fans should be balanced to provide Exhaust CFM (and Supply CFM) rating as
indicated on plans and hood submittal drawing.
Notes:
a.) The exhaust and supply (when provided) air flow rates were established under controlled
laboratory conditions.
b.) Greater exhaust and/or lesser supply air is required for complete vapor and smoke removal in
specific installations.
-Hood Troubleshooting
Guide to common hood problems:
1. Hood Lights not operating-
a. Bulb(s) not installed or burned out.
b. Dead short in light power wiring.
c. Defective light switch.
2. Hood not properly capturing smoke-
a. Exhaust fan belt broken.
b. Exhaust fan running backwards.
c. Excessive grease buildup on hood grease filters, in grease duct, or in exhaust fan.
d. Kitchen air balance not correct.
e. Exhaust fan motor, starter overload, or breaker tripped.
3. Excessive grease in duct and on roof-
a. Dirty hood grease filters.
b. Improper exhaust air balance resulting in excessive velocity through grease filters.

-Hood Maintenance
Note: Disconnect all sources of electrical power to unit prior to performing any maintenance.
Frequency of maintenance is determined by the severity of the application and amount of grease
generated.

1. Remove grease filters and clean by placing in dishwasher and washing with mild detergent.
2. Check hood grease container and empty as necessary.
3. Wipe clean the hood interior to remove any deposits of grease.
4. Clean the exhaust duct and exhaust fan wheel (This should be performed by a professional
duct cleaning service).
Note: Never use harsh abrasive cleaners on stainless steel surfaces.
