Kitchen Hoods • Type I and Type II 1
Receiving
Upon receiving the product, check to ensure all items
are accounted for by referencing the delivery receipt or
packing list. Inspect each crate or carton for shipping
damage before accepting delivery. Alert the carrier
of any damage detected. The customer will make
a notation of damage (or shortage of items) on the
delivery receipt and all copies of the bill of lading which
is countersigned by the delivering carrier. If damaged,
immediately contact your Accurex Representative. Any
physical damage to the unit after acceptance is not the
responsibility of Accurex, LLC.
Unpacking
Verify that all required parts and the correct quantity
of each item have been received. If any items are
missing, report shortages to your local representative
to arrange for obtaining missing parts. Sometimes it
is not possible that all items for the unit be shipped
together due to availability of transportation and truck
space. Confirmation of shipment(s) must be limited
to only items on the bill of lading. Filters are shipped
on a separate skid in their original packaging. Do not
remove factory packaging or install filters until just prior
to commissioning. Remove all other shipping/packing
materials.
Handling
Units are to be rigged and moved by the lifting brackets
provided or by the skid when a forklift is used. Location
of brackets varies by model and size. Handle in such
a manner as to keep from scratching or denting.
Damaged finish may reduce ability of unit to resist
corrosion.
Storage
Units are protected against damage during shipment. If
the unit cannot be installed and operated immediately,
precautions need to be taken to prevent deterioration of
the unit during storage. The user assumes responsibility
of the unit and accessories while in storage. The
manufacturer will not be responsible for damage during
storage.
The ideal environment for storage of the hood and
accessories is indoors, above grade in a clean, dry
atmosphere that is sealed from the elements. While in
storage, inspect equipment routinely. If any moisture,
dirt or other accumulations are found on the hood or
any of the parts, the source should be located and
eliminated.
Removing from Storage
As equipment is removed from storage to be installed
in their final location, it should be protected and
maintained as outlined in the Handling section above.

Kitchen Hoods • Type I and Type II4
Prior to Installation
Wall or Single Island Canopy Hoods
Prior to installation, check with the Authorities Having
Jurisdiction (AHJ) on clearance requirements to
structures surrounding the hood and other equipment.
Verify there is enough space to safely lift hood up into
its operating position and enough clearance around
the hood for components like fire system connections,
hood lights, hood control components, etc. Consider
access for servicing the equipment and the different
components when locating the hood.
If the hood is a grease hood (Type I), the UL label
located on the end panel on the inside of the hood
will provide pertinent information regarding the hood
installation. Information includes:
• Allowable cooking surface temperatures of the
cooking equipment
• Front and side overhang/underhang requirements
• Minimum exhaust (and possibly supply) airflow
requirements
• Hood lighting load information and restrictions
• Filter information
• Fire damper fusible link replacement information, if
applicable
With the hood still inside its packing crate, position the
unit beneath its installation location. Carefully remove
the packing crate and place some protective material on
the floor next to the crate to avoid damaging the hood
as it is tipped on its side. Tip the hood carefully onto the
protective material.
Bottom of Hood
Hood Installation Overview
1. If the hood is provided with filler panels, shipped
loose, install them now. See page 7, Filler Panel
Installation. Filler panels may be integral to the
hood, which requires no additional installation.
2. If the hood is equipped with Clearance Reduction
Methods, refer to pages 7 and 8 for special
considerations with hanging the hood.
3. If the hood is provided with hood/duct sensors or
thermostats, install them now. See the Installation
and Operations guide provided with the control
panel.
4. If the hood was provided with either exhaust
collars or supply collars that have shipped loose,
it is recommended that the exhaust and supply
openings are cut and collars are attached now,
prior to hanging the hood. See page 8, Installing
Duct Collars.
5 If the hood is provided with a back supply plenum
(BSP) install it now. See page 9, Installing the Back
Supply Plenum.
6. If possible, connect (weld) exhaust duct to the
hood while on the floor, unless it prohibits the hood
from being raised into place. For information on
ductwork, see page 9, Ductwork.
7. At this point, drill holes in the building structural
support system or utilize uni-strut to match up with
the hanger bracket holes. Then slowly and evenly
raise the hood into position and insert 1/2-inch
(12.7mm) diameter threaded rod (provided by
others) between the hanger brackets and structure.
For Type I hoods, the hood hanging height
requirements are given on the UL label. Typical
canopy hood hanging height will be 80inches
(198.12cm) off the finished floor.
Pallet
Protective Material
NOTE
If the hood is supplied with ceiling enclosures, the
height of the enclosures will typically be the distance
from the ceiling to the top of the hood. Use this
dimension to find the hood’s hanging height off of the
floor.
For questions regarding the supporting structure and
its integrity, either the contractor or structural engineer
needs to be consulted.
Kitchen Hoods • Type I and Type II 5
Wall or Single Island Canopy Hoods - continued
NOTE
All hanger brackets MUST be used and the hood must
be properly supported while lifting to prevent damage
or distortion to the hood.
NOTE
The hood MUST be hung evenly. If hung unevenly,
this may cause grease drainage problems. Provide
additional support if necessary so that the hood
doesn’t move in a manner that is acceptable with the
Authorities Having Jurisdiction (AHJ).
WARNING
When mounting the hood or any components against
the hood, never puncture or drill into the canopy. This
will void the hood listing and warranty.
8. If the hood was provided in sections with the
continuous capture option, once each hood
section is hung, install this option now. See page 9,
Continuous Capture Plenum Hoods.
9. If the hood was provided with any front or side
external supply plenums (other than the back
supply plenum), install these now. See page 10,
Installing Front/Side External Supply Plenums.
10. Install the remainder of both the exhaust and
supply ductwork. For further guidelines see page 9,
Ductwork.
11. If the hood is provided with any backsplash/
sidesplash panels, install them now. See page 11,
Installing Backsplash Panels.
12. If the hood is provided with any end skirts, install
them now. See page 12, Installing End Skirts.
13. If the hood is a Type I hood, it will require a fire
suppression system. Once the Type I hood(s)
and ductwork are fully installed, appliances are
in place and walls are complete, the fire system
should be completed. If the hood is provided with
a full factory-coordinated fire suppression system
installation, the certified fire system installer should
be contacted at this time to complete the final
hookups, testing and system certification based
upon manufacturer’s specification and local fire
codes. If the hood is not provided with either prepiping only or no fire suppression system, it is the
responsibility of a certified fire system installer
to install, test and certify the system based upon
manufacturer’s specification and local fire codes.
14. If the hood is provided with a control package,
these will need to be installed and wired by the
jobsite electrician. This typically includes wiring the
hood temperature sensors, hood lights and wiring
the fire suppression micro-switches. For general
hood electrical connections, see page 12, Electrical
Connections. If applicable, see the Installation
and Operations guide provided with the control
package.
15. If the hood is provided with enclosure panels,
install them now. See page 13, Installing Enclosure
Panels.
16. Install the rest of the hood accessories provided.
This may include grease filters or condensate hood
baffles, grease cups, light bulbs (provided by others
unless LED tube style), light globes, and trim strips.
It is recommended that the protective plastic sheeting
remain on the hood until fully installed to better protect
the product from scratching and marking. Once
removed, use stainless steel polish, such as BlueAway
or equivalent, to clean the hood and/or remove marks
or discoloration. Be sure to wipe with the grain and not
against it.
Kitchen Hoods • Type I and Type II6
Filler Panel Installation

Exhaust - As specified in NFPA 96, Ch. 7.5 (latest
edition), exhaust duct systems must be constructed in
the following manner:
Materials: Ducts shall be constructed of and supported
by carbon steel not less than 1.37 mm (0.054 in.) (No.
16 MSG) in thickness, or stainless steel not less than
1.09 mm (0.043 in.) (No. 18 MSG) in thickness.
Installation: All seams, joints, penetrations, and duct to
hood collar connections shall have a liquid-tight external
weld. If you have an automatic fire damper, please refer
to that manual for installation instructions now.
Supply - Supply ductwork (where applicable) should
be connected to the hood in a manner approved by the
local code authorities.
NOTE
For hoods with fire dampers in the exhaust and
supply duct collars, an access panel for cleaning and
inspection shall be provided in the duct. This panel
shall be as close to the hood as possible but should
not exceed 18 in. (45.72 cm).
For proper installation of duct collars when they are
shipped unattached, see page 8.

6. Fasten the back supply to the wall, going through the
lower back supply wall.
• These fasteners are to help maintain the location of
the back supply, and are not intended to hold the
weight of the back supply unit.
• The fasteners should not interfere with the
removable air diffusers.
2. After leveling, secure the
hoods together by tackwelding and/or bolting the
angles that are located at
the top of the hoods along
its width (Fig. 5).
3. Next, fasten the hoods
together at its inside
plenum profile using
u-clips and bolts (Fig.6).
Caulk this joint with NSF
Approved silicone caulk
(GE SCS1009 or its
equivalent). The caulk is
not provided.

PLENUM
1. Insert 1/2 in. (12.7 mm) diameter threaded rod (by
others) into hanger brackets on the external supply
plenum top. Raise and hang the external supply
plenum from adequate roof or ceiling supports.
NOTE
Ensure the external supply plenum is installed
flush with the hood front and is plumb and level by
adjusting the threaded rod(s). There should be no gap
between the bottom of the external supply plenum
and the hood after installation and adjustments are
completed.
2. The external supply plenum should be resting
lightly against the hood. The hood is only used to
position the plenum; it is not intended to support the
plenum. All hanger brackets on the external supply
plenum must be used and the plenum must be
properly supported while lifting to prevent damage or
distortion. The external supply plenum must be level
to operate properly.
NOTE
After hanging, secure the external supply plenum to
the hood (or to another external supply plenum) using
the supplied turnbuckle(s). Use caution tensioning the
turnbuckle. Too much tension may cause the bottom
of the external supply plenum to pull away from
the hood or cause the face of the hood to become
deformed.

3. It is recommended that caulk be applied at the
mating seams and surfaces of the external supply
plenum, the hood, and the wall. If the external supply
plenum is next to a wall, you will need to caulk
around the surface next to the wall. Caulk the joints
with NSF Approved silicone caulk (GE SCS1009, or
its equivalent). The caulk is not provided.
Installing the Supply Duct Collar to the Plenum
Place the duct collar(s) over the opening, fastening
with tack-welds at 1 to 2 in. (2.54 to 5.08 cm) intervals,
or sheet metal screws at 3 to 6 in. (7.62 to 15.24 cm)
intervals.
