TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PER-
SONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer. If you
have questions, contact the manufacturer at the address or telephone
number listed on the front cover of this manual.
2. Before servicing or cleaning unit, switch power off at service panel and
lock the service disconnecting means to prevent power from being
switched on accidentally. When the service disconnecting means can-not
be locked, securely fasten a prominent warning device, such as a tag, to
the service panel.
3. Installation work and electrical wiring must be done by a qualied per-
son(s) in accordance with all applicable codes and standards, in-cluding
re-rated construction codes and standards.
4. Sufcient air is needed for proper combustion and exhausting of gases
through the ue (chimney) of fuel burning equipment to prevent back-
drafting. Follow the heating equipment manufacturer’s guideline and
safety standards such as those published by the National Fire Protection
Association (NFPA), and the American Society of Heating, Refrigeration
and Air Conditioning Engineers (ASHRAE), and the local code authori-
ties.
5. When cutting or drilling into wall or ceiling, do not damage electrical
wiring and other hidden utilities.
6. To reduce the risk of re or electric shock, do not use this range hood
with an additional speed control device.
7. Ducted fans must always be vented to the outdoors.
8. To reduce the risk of re, use only metal ductwork.
9. Use with approved wiring only.
10. This unit must be grounded.
TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
1. Never leave surface units unattended at high settings. Boilovers cause
smoking and greasy spillovers that may ignite. Heat oils slowly on low or
medium settings.
2. Always turn hood ON when cooking at high heat or when cooking aming
foods.
3. Clean ventilating fans frequently. Grease should not be allowed to accu-
mulate on fan or lter.
4. Use proper pan size. Always use cookware appropriate for the size of the
surface element.
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A
RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING:*
1. SMOTHER FLAMES with a close-tting lid, cookie sheet, or metal tray,
then turn off the burner. BE CAREFUL TO PREVENT BURNS. If the
ames do not go out immediately, EVACUATE AND CALL THE FIRE
DEPARTMENT.
2. NEVER PICK UP A FLAMING PAN — You may be burned.
3. DO NOT USE WATER, including wet dishcloths or towels - violent steam
explosion will result.
4. Use an extinguisher ONLY if:
A. You know you have a Class ABC extinguisher and you already know
how to operate it.
B. The re is small and contained in the area where it started.
C. The re department is being called.
D. You can ght the re with your back to an exit.
* Based on “Kitchen Fire Safety Tips” published by NFPA.
WARNING
1. For general ventilating use only. Do not use to exhaust hazardous or
explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced impel-
lers, keep drywall spray, construction dust, etc. off power unit.
3. For best capture of cooking impurities and performance of re extin-
guisher, your range hood should be mounted so that the bottom of
the hood is 18-30” above the cooking surface, depending on model.
4. Please read specication sheets for further information and require-
ments.

The hood unit has two re alarm connections (discrete switches), each with its own trigger. A connection is
made to one output (Y#) and one common (C#) at the PLC. The output labeled Y0 is triggered by a fault from
the low temperature switch (150 F), pressure switch, or hose switch. Output Y1 is triggered by a high tempera-
ture switch (190 F) and a low pressure fault in the extinguisher tank (the re suppressant has discharged). You
may use either one connection or both, depending on your situation. When there is a fault, a buzzer in the unit
will sound and the power disconnect will turn o.
Local Alarm Connection: Connect to output Y0 and common C0
Remote Alarm Connection: Connect to output Y1 and common C1
To connect to the alarms, it is preferred that you use a spade terminal connector (supplied), but a stripped wire
is acceptable.
Connecting the alarm system in the conguration described above results in a normally open connection.
In addition to the PLC connections above, a second connection may be made to the re alarm switch installed in the unit. Unlike the
connection above, this switch does not require power to be fed to the hood in order to function. The re alarm switch is located above the
actuactor arm, beside the PLC assembly. The re alarm switch is activated when the actuator arm trips.
To connect the re alarm switch, wire the re alarm to the common connector and normally open or normally closed connection as shown.

Parts Included:
Step 1: Installing Conduit
Mount the pull box in an appropriate location according to local building
codes. Keep in mind you are supplied with 25 feet of cable and 3 elbow
pulleys. Install 1/2” conduit (not included) between the unit and the pull
box, using the pulleys as needed. Pull cable through the conduit, and
allow 8-12“ of slack to be left at the hood unit end. Be sure to abide by all
local building codes when installing conduit.
Step 2: Replace Safety Pin and Key (to prevent accidental discharge)
With the unit lowered into its service position, put the safety pin in
its slot at the top of the extinguisher tank. Also replace the safety
key in its slot in the actuator arm. Then remove the cable from the
actuator arm.

Step 3: Install Cable and Pin to hood
Thread the cable through the conduit, with the pin reaching the unit. Remove the
grease lter. In the upper right corner, nd the two pulleys as illustrated to the right.
Hold the rear-most pulley in place. From the top of the unit, replace its pin with the one
on the cable. Push the pin through the pulley until you hear it click in place. Go back to
the actuator arm and rehook cable onto the arm.
WARNING: You must allow for 8-12”of slack in the cable to sit at the pull face. Failure to do so will cause
the unit to discharge the next time the unit is lowered into its service position.
CAUTION: Make sure the cable does not become caught on any part of the hood or conduit, or the cable
will not be able to be pulled, and the unit will not discharge.
Step 4: Install Cable to Pull Face
With the unit in its lowered position, attach the cable to the pull face by crimping a loop
in the cable through the hole on the back side of the handle. Be sure cable is securely
crimped to withstand at least 50 lbs of pull force. Leave no more than 12”of slack in the
line on the pull face end, but maintain 8-12”. To make this easier, the handle may be
removed by loosening the set screw in one of the studs, and sliding the red plastic rod
out. Attach the pull face to the pull box already mounted on the wall, collecting any slack
into the pull box. Do not allow slack cable to collect above the hood.

Once the hood has been installed, it may be necessary or desired to test the unit with a test tank. This is a tank lled only
with pressurized nitrogen (Need to order separately).
1. Following the “Removing the Extinguisher Tank” instructions in the service manual, remove the extinguisher tank and
replace it with a test tank.
2. The unit can be actuated one of two ways:
A. Cut Test Links: Replace the actuator arm’s safety key. Loosen the turnbuckle in the fusible link cable assembly (underside
of hood). Replace one of the fusible links with a test link. Re-tighten the turnbuckle to the proper tension. Remove the safety
key and raise the unit to its operational position. To test, cut the test link with wire cutters or similar.
B. Manual pull kit (if installed): Raise the unit to its operational position after the test tank has been installed. Remove the
plastic break rod from the pull face with an allen wrench (refer to manual pull station appendix for more detailed infomation
on this). Pull the handle to actuate the unit. Refer to the manual pull kit appendix on how to return the pull station to an
operational state.

Turnbuckle Fusible Link
WARNING: The safety pin must be in place in the extinguisher tank until the unit is ready to
be returned to service or to be tested. Always wear safety glasses during this procedure.
3. Nitrogen should be released from each nozzle simultaneously.
4. Replace the test tank with the extinguisher tank, the test link with a fusible link, and replace the unit to its operational
position. The unit is now ready to be put into service.
WARNING: Be careful of the protective caps on the nozzles. These
will y o the nozzles when the unit is actuated. Always wear safety
glasses during this procedure.

The D1000 is the rst range hood with an integrated re suppression system. It functions as a standard ventilation
range hood with the added capability to suppress stove top res.
Designed for use over a standard 30” and 36” residential range, it uses a mechanical, commercial style automatic re
suppression system.
Refer to the illustration below to familiarize yourself with the following functions.
• A PLC provides an internal alarm plus connections for up to two external alarms that may go to a local alarm panel
and/or remote location, i.e. the local re department.
• The unit is powered from standard 115 VAC / 60Hz / single phase. A main Power Switch is located at the upper left
of the front surface.
• For normal daily use, the unit provides a fan speed control knob and a light switch for the light.
• A Reset Button (white) is provided to energize the PLC and the main power disconnect contactor (electric range)
or valve (gas stove). Upon initial power up, the control system is not enabled and this reset button needs to be

Moving the unit between‘operating’ and ‘service’ positions
All D1000 models have been congured as a standalone unit mounted to a wall plate. As such, the unit may
easily be tilted down into a service position, giving you access to the electronics and extinguisher tank, or be re-
moved completely for maintenance and cleaning. Provisions have been made to facilitate easy removal includ-
ing a minimal amount of fasteners and modular electrical connections.
To place the unit in the service position, a few simple steps are required. Be sure to wear safety glasses at all
times during this process:
1. Shut the unit o with the power switch on the front of the hood;
2. Remove the grease tray then the grease entrapment lter;
3. Loosen and remove the brass knurled service nuts that are on the rear inside wall of fan housing compart-
ment. On units with a ducted fan, remove the two thumbscrews located at the top inside near the fan intake
(refer to illustration below). Slowly lower the unit;
4. The unit will now freely pivot downward to a stop position. A safety cable is provided to prevent the unit
from falling or lowering too far.
5. Place safety pin in the tank valve to avoid accidental discharge.
With the unit in this position, basic servicing and cleaning may be performed, including servicing the extin-
guisher tank assembly.
To move the unit back to the operating position, simply reverse the process as outlined above.
WARNING: An electrical shock hazard is present at the electrical compart-
ment whenever there is power to the hood. Use caution when working
around this device while the unit has power.
WARNING: Be careful while working with the unit in the service position.
Release of the cable system or applying force to the tank valve assembly may
cause discharge of the tank. The high pressure discharge has the potential to
cause skin or eye damage and injury!

Cleaning the Hood
To remove built up grease and cooking debris, clean the unit thoroughly with mild detergent and water. Be
careful when using abrasive cleaning pads as they may scratch or mar the stainless steel surfaces. The grease
entrapment lter, front discharge grille and grease tray are dishwasher safe. The carbon lter cannot be washed,
and should be replaced periodically as needed.
Inspect the nozzle caps
The nozzle caps should be inspected and cleaned. All 5 nozzles should have protective caps installed. If neces-
sary, remove the caps and check for build up of debris or any signs of clogging of the nozzle orice. If clogging
is suspected, remove the nozzle with a 7/16” wrench, and ush with hot water until it ows freely through the
nozzle. Replace the nozzle and protective cap.
Replacement caps and nozzle O-rings are available from DFP or your distributor.
Inspect Fusible Link System*
Periodic inspection of the fusible link system ensures the unit is ready to work in the case of a re.
1. Place safety pin in tank valve.
2. Remove tank from hood.
3. Remove tension from cable system by loosening the turnbuckle.
4. If the fusible links need to be replaced, you may order some by calling your local distributor.
5. Inspect pulleys and cable. Pulleys should rotate freely and cable should be exible. Everything should be free
of grease build-up.
6. Tighten the turnbuckle, reapplying tension to the stainless steel rope, making sure the cable is running
through the pulleys properly and there are no kinks or knots.
WARNING: The protective caps stay on the nozzles at all times. In the event
of a discharge, the caps will blow o on their own.

Hydrostatic testing and new liquid agent, or tank replacement is recommended at ten-year intervals. The man-
ufacture date is stamped on the top of the tank. This should be performed by an authorized technician or at the
manufacturer’s facilities. Material safety data sheets are available from DFP.
Lighting
Illumination is provided by a 60 Watt medium-base shatterproof incandescent light bulb. To replace, make sure
the light switch is in the “o” position, and then gently unscrew the bulb. (Bulb: 60A15/TF)
WARNING: Rubber gloves and safety glasses should be worn during ser-
vice or inspection of the tank. If contact with skin or eyes occurs, ush
immediatly with water for 15 minutes. If irritation persists, contact a physi-
cian. If taken internally, do not induce vomiting. Dilute with water or milk
and contact a physician.
WARNING: If grease build up on the cable is not kept to a minimum, the ca-
ble could become sti and will not discharge the suppressant in the event
of a re.
Removing the Extinguisher Tank
1. Lower the hood to its service position
2. Insert the safety pin in the valve head so that accidental release of the suppressant does not occur.
3. Unlpug the pressure switch wire and move it out of the way for now.
4. Disconnect the discharge hose from its tting located inside the unit closest to the user.
5. Unscrew the two wingnuts holding the bracket for the tank.
6. Lift the tank out of the hood.
7. To replace the tank, simply reverse these steps.

Programmable Logic Controller (PLC)
LED Indications
The PLC operating system is designed to enhance the functionality of the unit and the safety of the cooking
environment.
The system relies on input from a set of thermostats to control the fan and shuto power to the stove when the
temperature reaches preset points.
As the temperature rises, the PLC monitors the environment with the 3 thermostats. The board is programmed
to respond to 2 temperature thresholds: the rst at 150 deg F and the second at 190 deg F.
At the rst temperature threshold the ventilation fan will turn on, REGARDLESS OF THE FRONT PANEL SWITCH
SETTING.
At the second temperature threshold, several events happen:
1) The power disconnect to the stove (valve or contactor) is de-energized, shutting o power to the stove;
2) The “local” alarm output is tripped, indicating a trouble condition with the unit. This output is from
contacts C0 and Y0 on the PLC.
3) The on-board audible alarm sounds (high pitched tone).
