WARNING
WARNING - TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
a) Use this unit only in the manner intended by the man-
ufacturer. If you have questions, contact the manufac-
turer.
b) Before servicing or cleaning unit, switch power off

WARNING
WARNING - TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
a) Installation work and electrical wiring must be done by
qualified person(s) in accordance with all applicable
codes and standards, including fire-rated construc-
tion.
b) Sufficient air is needed for proper combustion and
exhausting of gases through the flue (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 for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and the local
code authorities.
c) When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
d) Ducted fans must always be vented to the outdoors.
WARNING
For general ventilating use only. Do not use to exhaust
hazardous or explosive materials or vapors.

Important Safety Instructions
• Do not install or operate this unit if it has been dam-
aged, dropped, has damaged electrical wiring or is
not working properly. If the product is damaged when
received, immediately contact the dealer or builder.
• Use this blower only for its intended purpose as out-
lined in these instructions. This blower is not intended
for commercial use.
• All planning, installation work and electrical wiring
must be performed in accordance with all governing
codes and ordinances, including fire-rated construc-
tion. Contact your local building department for fur-
ther information.
• Install or locate this appliance only in accordance
with these installation instructions and the Dacor
hood or downdraft vent installation instructions.
Improper installation, adjustment, alteration, service
or maintenance can cause serious personal injury or
property damage.
• Before installing or servicing the in-line blower, make
sure that power to the wiring is turned off at the cir-
cuit breaker or fuse box. Make sure that the service
panel is locked or tagged to prevent power from
being switched on accidently.
• To reduce the risk of electric shock or fire, the total
combined current draw of the in-line blower and the
hood or downdraft vent must not exceed the maxi-
mum rated input current of the hood or downdraft
vent.
WARNING
General Safety Precautions
To reduce the risk of fire, electric shock, serious injury or death when using this blower, follow basic safety precautions,
including the following:
• The installer must show the customer the location of
the fuse or circuit breaker panel so that the customer
knows where and how to turn the power off.
• Never allow the filters or vent openings on the hood
or downdraft vent to become blocked or clogged. Do
not allow foreign objects, such as cigarettes or nap-
kins, to be sucked into the vent holes.
• Clean the filters and all grease-laden surfaces around
the hood or downdraft vent often to prevent grease
fires and maintain performance.
• Use only duct work constructed of materials deemed
acceptable by state, municipal and local codes.
• Tape all duct joints securely to prevent combustion
by-products, smoke or odors from entering the home.
Doing so will also improve system efficiency.
• Do not route electrical wiring near hot surfaces.
• Do not ground the appliance with the neutral (white)
house supply wire. A separate ground wire must be
utilized.
• To prevent a damaged or non-functional system,
complete electrical connections properly. Follow the
wiring diagrams carefully in the hood or in-line blower
installation instructions to ensure a proper installation.
After installation or service, make sure that all blower
wires are tightly connected to their respective termi-
nals.

Installation Planning
WARNING
To avoid the risk of fire due to the unit overheating:
• DO NOT install this blower with a hood or raised vent
that has an internal blower.
• DO NOT install more than one blower to increase
the length of the duct run. Even small differences
between blower air flow rates can greatly reduce the
air drawn by the hood or raised vent.
• For optimal performance, consult a qualified HVAC
specialist before installation.
• Consult the installation instructions for the raised vent
or hood for complete layout and duct system plan-
ning instructions. Observe all location and duct system
design instructions.
• To minimize noise, install the blower at the mid-point
between the raised vent or hood and the duct system
exhaust. Minimum recommended distance from the
vent/hood or exhaust is 5 feet.
General System Design Notes
• Wire the remote blower to turn on when the raised
vent or hood is turned on by running a piece of conduit
parallel to the duct work and connecting it to the raised
vent or hood on one end and the in-line blower on the
other. There are two 1/2” electrical access hole knock
outs in the sides of the blower’s electrical access panel.
Electrical Access Knock-outs
• Select a location that can properly support or can be
reinforced to support the weight of the blower.
Model Number Weight
ILHSF8 22 lbs. (10 kg.)
ILHSF10 31 lbs. (14 kg.)
• Install the blower so that it can be removed if service is
required.
• Plan the installation so that all minimum dimensions
are met or exceeded. All contact surfaces between the
blower and any mounting surfaces must be solid and at
right angles.
• The mounting surface must be thick enough to accom-
modate screws 2” in length.
Electrical Specifications
Electrical Supply Requirements
• The power for this blower is supplied via 1/2” 3-wire
conduit (not included) by an approved Dacor hood or
raised vent. The conduit is installed between the hood
or raised vent and the blower and shall be terminated
on each end by a 1/2” UL certified strain relief. The
power is turned on and off by the power switch on the
approved ventilation device.
• The correct voltage, frequency and amperage must be
supplied to the hood or raised vent and the blower from
a grounded, single phase circuit that is protected by a
properly sized circuit breaker or time-delay fuse. The
circuit must have the capacity to supply the combined
power requirements for the hood or raised vent and the
in-line blower. See the installation instructions for the
hood or raised vent to determine total power require-
ments in combination with the blower electrical specifi-
cations.

tions for additional parts required.
Installation
WARNING
• If the electrical service provided does not meet the
power requirements for the hood/raised vent and the
blower combined, do not continue with the installation.
Contact a licensed electrician to correct the situation
before continuing.
• Failure to connect the wiring as specified may result
in an electric shock hazard and/or improper blower
operation.
• To avoid the risk of fire or electric shock, turn off
power at the circuit breaker panel or fuse box before
connecting the blower to the power source.
Blower Mounting
1. Hold the blower steady in the mounting location. Make
sure that the “AIR FLOW” arrow on the chassis points
toward the exhaust duct’s path to the outdoors.
2. Attach it using four (4) #10 x 2”, round head screws.
Insert the screws at an angle as shown.
Electrical Installation
1. Run the conduit line used to supply power from the
installed raised vent or hood to the in-line blower paral-
lel to the duct work.
2. Make sure that power to the raised vent or hood is
disconnected or turned off at the circuit breaker or fuse
box.
3. Remove the electrical access cover from the in-line
blower to expose the power terminals.
4. Remove one of the conduit knock-outs from one side of
the blower.
5. With the UL certified strain relief attached to the end of
the conduit, feed the end of the conduit into the hole

Verifying Proper Operation
WARNING
Read the raised vent or hood use and care manual
completely before operation.
Test the blower operation according to the Verify Proper
Operation section of the hood or raised vent installation
instructions.
1. If the blower does not work, check all input and output
power connections at the hood or raised vent.
2. Check the blower power terminal connections.
If the installation still does not work, contact Dacor
Distinctive Service at (800) 793-0093 ex. 2822. Do not
attempt to repair the blower, hood or raised vent yourself.
Be sure to have all model and serial numbers from the
product data labels available when you call.
Dacor is not responsible for the cost of correcting problems
caused by a faulty installation.
Electrical Installation (continued)
6. Strip the three conduit wires.
