WARNING:To reduce the risk of a range top grease fire:

A) Never leave surface units unattended at high settings. Boilovers cause smoking and greasy

spillovers that may ignite. Heat oil slowly on low or medium settings.
B) Always turn hood “ON” when cooking at high heat or when cooking flaming foods.
C) Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
D) Use proper pan size. Always use cookware appropriate for the size of the surface element.

Make-Up air may be necessary to prevent air flowing down chimney, unsealed door, window, or fireplace

opening.

WARNING: To reduce the risk of fire, electrical shock, or injury to persons, observe the following
guidelines.

A) Installation and Electrical Wiring Must Be Performed By Qualified Personnel In Accordance With All

Applicable Codes & Standards, Including Fire-Rated Construction.

B) To Prevent Backdrafting, sufficient air is needed to maintain proper combustion and safe exhausting

of gases through the flue (chimney) of fuel burning equipment. Follow the cooking equipment

manufacturers guideline and safety standards such as those published by the National Fire

Protection Association (NFPA) and the American Society for Heating, Refrigeration and Air

Conditioning Engineers (ASHRAE), and the local code authorities.

C) Use caution when cutting or drilling into walls or ceilings as not to damage electrical wiring and

other hidden utilities.

CAUTION:To Reduce the risk of fire and to properly exhaust air, be sure to duct air to outside. -do not
vent exhaust air into spaces within walls or ceiling, nor into attics, crawl spaces, or garages.

NOTE: unit MUST be vented to the outside of the building.

WARNING:To reduce the risk of electrical shock or injury to persons, all vent hoods must be installed

with ventilators that have been approved for use with the hood.

BACKDRAFT DAMPER:

We recommend that a backdraft damper be used in all Vent Hood installations. Cold weather installa­tions necessitate the use of a backdraft damper to minimize the flow of cold air into the room. A non­metallic thermal break should also be installed to minimize conduction of outside temperatures
through the ductwork. Locate the thermal break as close as possible to where the ducting enters the
heated portion of the house.

PLANNING THE INSTALLATION:

Before beginning installation of the Vent Hood and Ventilator, PLAN OUT the entire installation proce­dure beforehand, considering the following areas:

1. HOOD SIZE & LOCATION- (The hood should be as wide or wider than the cooking appliance with
the hood being centered on the appliance.Vertically, the bottom of the hood should be between 30”-
36” above the appliance cooking surface).

2. DUCTING- (ducting transitions, air flows to outside? Use of Backdraft damper? ...etc.)

3. ELECTRICAL REQUIREMENTS- (120 Volts, 60 Hz, 15 AMP Service, Local Codes...etc.)

4.ADEQUATE MOUNTING SURFACES- (location of wall studs, additional support for safe wall
mounting...etc.)

HANDLING NOTE- This Hood has been inspected prior to shipping to be free of defects. Due to the

weight of the Vent Hood and Ventilator and to prevent scratching or denting the unit, we recommend the use of
two installers to move, place, and secure the Vent Hood to avoid personal injury or damage to the Hood.

INNER LINER REMOVAL:

The DCS Professional Vent Hood has been designed into (2) major assemblies to accommodate easy
and safe installation. The following procedure is best done with the Hood on its back on a padded sur­face. The inside liner assembly can be separated from the outer hood assembly by removing the (12)
inner perimeter screws- (3 each side/front/back). Once these screws have been removed, the liner
assembly can slide down to gain access to the male/female disconnect plug- See Fig.8 on page 5.After
the disconnect plug has been unplugged, the liner assembly can be set aside until the hood has been

installed into the soffit or wall.

SITE PREPARATION:

This DCS Professional Vent Hood has been designed to accommodate installation into a

1) soffit structure (ceiling mount), or, for sites without a soffit structure.

2) directly into the wall through holes provided in the rear panel of the vent hood (wall mount). When

mounting the hood to a soffit, it is recommended to also utilize the rear panel holes to gain addi­tional stability and minimize any vibration noise. We suggest that the final framing and wall finishing
be done with the vent hood at the site to more accurately locate ductwork and electrical service.

CONSTRUCT SOFFIT FRAMING:

1) For a site with a soffit, use 2” x 4”s to construct the soffit framing as shown below in Fig. 1. Note

that a minimum opening of 10” is needed to accommodate the ductwork. With the centerline of
the installation marked, nail down the 2” x 4”s (wide side down) so that their inner edges are those
specified from the centerline. -see Figs.1 & 3 pg.7

Note: The second (outer) set of 2” x 4”s are not necessary on the 30” Models installation.

2) Make 2 wood shims (2” x 10-1/2” x drywall thickness). Attach them to the framing as shown in

Fig.2. Mount shims flush with inner edges of framing and with front edges 11-1/2” from finished back
wall.

INSTALL VENT HOOD INTO SOFFIT:

At this point in the installation process, the inner liner should be removed from the Hood and set aside
(see-Pgs 5 & 6).With the liner set aside, there is clear access to the Soffit mounting holes and wall
mounting holes in the rear panel of the unit.

Once the soffit framing has been completed, place assembled vent hood (hood, rough-in kit, and
ventilator) into place and secure hood to the soffit frame with 6 wood screws.

NOTE: Additionally, we recommend the installer utilize the holes provided in the rear panel of the hood to
secure the hood to the rear wall and minimize any noise and vibration of the unit.

NOTE: Assure that the mounting screws are long enough to be driven through the wood shims into the
installed 2” x 4”s for total support. -see fig.3

SITE PREPARATION:

In cases where the installation site does not have a soffit structure, the Vent Hood assembly may be
secured directly to the wall from the rear of the unit.

NOTE- When installing the vent hood directly to the rear wall, an adequate structural wall support (studs)
must exist to secure the unit.

NOTE- The DCS Duct Cover should be ordered and installed when installing the vent hood in a site without a
soffit. DCS offers both a 6” and 12” height Duct Covers. Keep the 6 or 12 inch dimension in mind when allow-
ing for clearance between the top of the Vent Hood and the ceiling. (see Fig. 4)

1. With the Vent Hood width, and installation site in mind, mark the centerline of the installation.

2. See the chart in Fig.4 to determine the centerline to centerline dimension of wall mounting holes
for the particular model being installed.

3. Cut away enough drywall (if installed) to expose 2 vertical studs (1 on each side of the Hood
center line) It will be necessary to A) construct a plywood wall insert (See Fig 5) or B) install
aligning wall studs. (See Fig 6).

WALL MOUNTING:

After an adequate wall structure has been completed, secure the DCS Duct Cover (6” or 12”) to the
top of the vent hood. Carefully lift the hood with the duct cover into the installation site and secure
the hood into the wall structure with 6 (six) mounting screws. Once the Hood assembly has been
secured to the wall, the front of the Soffit Chimney may be removed for ductwork connections.

TO FINISH THE INSTALLATION:

Once the ventilation hood has been mounted in
place it will be necessary to install the electrical
service. All electrical work should be done by a
qualified electrician and must conform to all local
standards. Refer to the wiring diagrams on Pgs.
14-15, for proper hook-up and grounding.

NOTE: Black=live,White=neutral, Green=ground

Complete installation by making ductwork con­nections, testing unit functions, and installing & fin­ishing drywall.

CARE AND USE:

CONTROLS- We recommend you turn your
hood on before you begin cooking to establish fresh air flow.After you've finished cooking, let the
blower run for a few minutes to clear the air and help keep the kitchen fresh and clean.

BLOWER- The blower is operated with 2 controls. The switch adjacent to the speed control turns the
blower on/off, while the speed control adjusts the blower speed. Turn the speed knob clockwise to
increase and counterclockwise to decrease the blower speed.

HOOD LIGHTING- A single switch controls both lights. Use only 50W Max. Halogen Narrow Flood
replacement bulbs.

CAUTION: Halogen lamps are constructed of a glass bulb with a pressurized internal filament tube that
operates at high temperatures and could unexpectedly shatter. Should the outer bulb break, particles of
extremely hot glass could be discharged into the fixture enclosure and/or surrounding environment, thereby
creating a risk of personal injury or fire.When replacing the bulb, let the bulb cool, and assure that power to
light has been turned off. Never allow hot bulb to come into contact with water.

Do Not Touch the Hood Light Bulbs when in use.They may be hot enough to cause injury.

WARMING LAMPS- Each warming lamp is controlled by its own on/off switch. Use only R40 size,
250W Max. Infrared bulbs.
FILTERS- Filters should be cleaned frequently in a detergent solution and are dishwasher safe. Empty
grease collection tray/s regularly. Remove filter/s by gently pulling up and out. Grease collection tray/s
are beneath each filter/s.

UNPLUG the BLOWER MOTOR BEFORE CLEANING VENTILATOR.

-Remove filters to access blower motor plug. Vacuum blower to clean. Do not immerse in water.

-Do not allow an excessive accumulation of grease. -Use a mild detergent when cleaning.

-Do not use harsh abrasives, steel wool pads, or abrasive cloths.

GENERAL:

- When planning the path for ducting to the outside, keep in
mind the following guidelines:

- Minimize use of elbows and transitions in ductwork as to
maximize air flow to outside of building. An efficient airflow
path contributes to the overall efficiency of the Vent Hood.

- DCS recommends the use of smooth wall ducting, not
flexible ductwork.

- Transitions are required from rectangular to round ducting

DCS-IB12 BLOWER Requires one of the following 4-1/2” x 18” to 10” round transitions

(purchase separately)
Model 19052-01-Vertical discharge
Model 19052-02-Rear discharge
Model 19052-03-Left discharge

- Duct tape may be used at ducting joints.

DCS-VH-48 / DCS-VH12-36 REQUIREMENTS:

- DCS recommends the use of 10” round ducting which provides 78.6 sq. In. of surface area.

- Alternate duct sizes in rectangular style may be used. If a rectangular duct style is used, the duct
must equal at least 78.6 sq. In. for best results. (Example- 3-1/4” x 24” duct = 78 sq. In.)

- Maintain consistent ducting square area as to avoid reduced air flow. [ie.- With a VH-48 Hood,
connecting a 4”x13” (52 sq. In.) to a 10” round (78.6 sq. In.) is not recommended]

DCS-VH-36/30 REQUIREMENTS:

- DCS recommends the use of 7” round ducting which provides 34.7 sq. In. of surface area.

- Alternate duct sizes in rectangular style may be used. If a rectangular duct style is used, the duct
must equal at least 34.7 sq. In. for best results.

DUCT ACCESSORIES:

- Wall Caps and Roof Caps must have free open area equal to duct size diameter.

- Note that a Sealed Back Draft Damper may reduce air delivery.
