Reading Pressure
Gauge
The included pressure gauge for the Model
G0638HEP provides an easy way to check if the
filters require cleaning or replacement.
When the gauge displays more than 6 Aq (see
Figure 1), clean the filters according to Cleaning
Filters and Rinsing Filter on Pages 47–48 of the
owner's manual.
6.0 Aq
Figure 1. Location of 6 Aq on pressure gauge.
Older filters do not get as clean as new ones, so
the pressure will not drop as substantially after
the first cleaning. When the air pressure no longer
drops below 6 Aq with cleaning, replace the filters.

We strongly recommend using a generalpurpose silicone sealant on all mating
surfaces during assembly process. For
those components assembled with a rubber
gasket between them, apply sealant evenly
on both sides of gasket before assembly.
Note: Only finger tighten hardware.
IMPORTANT: Be sure to build frame using
bolt holes indicated in Figures 7–9 and 23.

Inventory
The following is a list of items shipped with your
machine. Before beginning setup, lay these items
out and inventory them.
If any non-proprietary parts are missing (e.g. a
nut or a washer), we will gladly replace them; or
for the sake of expediency, replacements can be
obtained at your local hardware store.
Inventory
NOTICE
If you cannot find an item on this list, carefully check around/inside the machine and
packaging materials. Often, these items get
lost in packaging materials while unpacking or they are pre-installed at the factory.
I. Intake Cylinder ........................................... 1
Outlet Port .................................................. 1
The HEPA cyclones are assembled largely the
same way as the regular cyclones, but with the
HEPA filter components being installed in place of
the regular canister filter assembly. To assemble
your HEPA cyclone, open the Assembly section
in the Owner's Manual and follow those steps only
when specified below.
To ensure the integrity of the HEPA filtration
system and prevent fine dust from leaking
out before it reaches the filters, we strongly
recommend using a general-purpose silicone sealant on all mating surfaces during the assembly process. For those components assembled with a rubber gasket
between them, apply the sealant evenly on
both sides of the gasket before assembly.
2. Follow assembly instruction Steps 14 –27 in
owner's manual.
. Position outlet gasket around opening on

blower housing (see Figure 7), then attach
outlet to blower housing (see Figure 8) using
3
⁄8" x 1" hex bolts, (20) 3⁄8" flat washers,
(10)
and (10)
3
⁄8" nuts.

Machine Description
The Model G0637/G0638 is a 2-stage cyclone
wood dust collector capable of collecting dust
from multiple machines running simultaneously.
Cyclonic action separates the heavy dust and
chips from the fine particles and drops them
into the steel collection drum. Any remaining fine dust travels past the impeller and is
trapped by the pleated cartridge filter made
of spun-bond polyester. With the use of the
cable and pulley system on the outside of the
filter assembly, the caked dust is forced down
into the collection bag.

The machine is controlled directly by the
magnetic switch mounted to it or by the IR
remote switch—each control includes timer
options.

Glossary Of Terms
The following is a list of common definitions, terms and phrases that relate to dust collection and dust collectors in general. To get the most out of this manual, familiarize yourself with these terms before reading.
Air Suction Capacity: The maximum volume
of air (rated in CFM) that a dust collector can
move, at the inlet, when fully assembled and
not connected to any ducting.
Branch Line: A secondary length of duct that
connects a dust-producing machine to the
Main Line of a permanent dust collection system. The minimum recommended Velocity for
branch lines is 4000 FPM.
Collection Bag/Drum: The part of the dust col-
lector that holds the majority of captured dust.
CFM (Cubic Feet per Minute): A measurement
describing the volume of air that moves through
an area in one minute. CFM = Velocity (FPM) x
Cross-Sectional Area of Duct (ft.
Cyclone: A type of two-stage dust collector that
uses centrifugal force to remove large dust particles before they can reach the filter.
Duct (Ducting): Metal/plastic pipe or hose that
connects the dust collector to dust-producing
machines. Typically available in rigid or flexible
options.
Dust Collection System: The entire assembly of
dust collector, duct, and fittings used to capture
dust from machines.
Dust Port/Hood: The part of a dust-producing
machine that connects to dust collection duct.
2
).
Duct Grounding: A method of using bare wire
with plastic duct to safely dissipate static electricity buildup during operation.
Main Line: The primary length of duct that con-
nects the dust collector to the branch lines of
a permanent dust collection system. The minimum recommended Velocity for main lines is
3500 FPM.
Machine CFM Requirement: Indicates the mini-
mum amount of airflow required at the dust port/
hood of a dust-producing machine for adequate
removal of the waste produced. Essentially, the
performance required by the Dust Collection System after accounting for the drop in CFM
from the static pressure loss of the duct line
between the machine and the dust collector.
Powered Air Filter: An independently operated
machine that removes fine dust suspended in
the air. Typically operated during and after dustproducing operations as a secondary method
to improve the air quality in a shop.
Single-Stage Collector: A type of dust collector
where all collected chips and dust are expelled
directly into the filter.
Static Pressure: Expressed in units of inches of
water, this describes the difference in pressure
between the air inside and outside the dust collector. It is a measure of the suction created by
the blower.
Filter: The part of the dust collector that prevents
the majority of suctioned dust from returning to
the shop environment. Filters are rated by the
size of fine dust (measured in microns) that can
pass through them.
Fittings (Y's, T's, Elbows, etc.): The various
duct connections that allow the branch and
main lines of a dust collection system to be
routed from the machine to the dust collector.
-4-
Two-Stage Collector: A type of dust collector
where large/heavy waste is captured in a separate container before the airflow reaches the
filter. Benefits include longer operation times
between filter maintenance or replacement.
Velocity: The speed of airflow movement, mea-
sured in FPM (Feet Per Minute). Velocity =
Volume (CFM) / Cross-Sectional Area of Duct

Safety Instructions for Machinery
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained operators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, disconnect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make workshop kid proof!
DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machinery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.
ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST.

adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are not approved safety glasses.
intended for collecting wood dust and chips from
woodworking machines. DO NOT use this dust
collector to collect metal, dirt, pebbles, drywall,
asbestos, lead paint, silica, liquids, aerosols, or
any flammable, combustible, or hazardous materials.
HAZARDOUS DUST. Dust created while using
machinery may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and always wear a NIOSH-approved respirator to
reduce your risk.
DUST ALLERGIES. Dust from certain woods
may cause an allergic reaction in people and animals. Make sure you know what type of wood dust
you will be exposed to in case there is a possibility
of an allergic reaction.
WEAR RESPIRATOR. Fine dust that is too
small to be caught in the filter will be blown into
the ambient air during operation. Always wear a
NIOSH approved respirator during operation and
for a short time after to reduce your risk of permanent respiratory damage.
EMPTYING DUST. When emptying dust from the
collection container, wear a respirator and safety
glasses. Empty dust away from ignition sources
and into an approved container.
DISCONNECTING POWER SUPPLY. Turn the
switch OFF, disconnect the dust collector from
the power supply, and allow the impeller to come
to a complete stop before leaving the machine
unattended or doing any service, cleaning, maintenance, or adjustments.
REGULAR CLEANING. Regularly check/empty
the collection bags or drum to avoid the buildup
of fine dust that can increase the risk of fire. Make
sure to regularly clean the surrounding area where
the machine is operated—excessive dust buildup
on overhead lights, heaters, electrical panels, or
other heat sources will increase the risk of fire.
SUSPENDED DUST PARTICLES AND IGNITION
SOURCES. DO NOT operate the dust collector in
areas were explosion risks are high. Areas of high
risk include, but are not limited to, areas near pilot
lights, open flames, or other ignition sources.
FIRE SUPPRESSION. Only operate the dust collector in locations that contain a fire suppression
system or have a fire extinguisher nearby.
IMPELLER HAZARDS. DO NOT place your
hands or tools near the open inlet during operation
for any reason. The powerful suction could easily
cause accidental contact with the impeller which
will cause serious personal injury or damage to
the machine. Always keep small animals and children away from open dust collection inlets.
AVOIDING SPARKS. DO NOT allow steel or
rocks to strike the impeller—this may produce
sparks. Sparks can smolder in wood dust for a
long time before a fire is detected. If you accidentally cut into wood containing tramp metal (nails,
staples, spikes, etc.), immediately turn OFF the
dust collector, disconnect it from power, and wait
for the impeller to stop—then empty the collection container into an approved airtight metal
container.
OPERATING LOCATION. To reduce respiratory exposure to fine dust, locate permanently
installed dust collectors away from the working
area, or in another room that is equipped with a
smoke detector. DO NOT operate the dust collector in rainy or wet locations—exposure to water
may create an shock hazard or decrease the life
of the machine.
STATIC ELECTRICITY. Plastic dust lines generate high amounts of static electricity as dust chips
pass through them. Although rare, sparks caused
by static electricity can cause explosions or fire.
To reduce this risk, make sure all dust lines are
thoroughly grounded by using a grounding wire.

SECTION 2: POWER SUPPLY
Before installing the machine, consider the availability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrican or
qualified service personnel in accordance with all
applicable codes and standards.
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid overloading the machine during operation and make
sure it is connected to a power supply circuit that
meets the requirements in the following section.
This machine can be converted to operate on a
220V power supply (refer to Voltage Conversion
instructions). This power supply must have a verified ground and meet the following requirements:

to be disconnected (isolated) from the power
supply when required. This installation must be
performed by an electrician in accordance with all
applicable electrical codes and ordinances.
In the event of a malfunction or breakdown,
grounding provides a path of least resistance
for electrical current to reduce the risk of electric
shock. A permanently connected machine must
be connected to a grounded metal permanent wiring system; or to a system having an equipmentgrounding conductor. All grounds must be verified
and rated for the electrical requirements of the
machine. Improper grounding can increase the
risk of electric shock!

This subsection is only provided for troubleshooting. If you discover during the test run that the
machine will not operate, or that the impeller spins
backward, the power connections may be wired
out-of-phase. Without the proper test equipment
to determine the polarity of the power source legs,
wiring machinery to 3-phase power may require
trial-and-error. Correcting phase polarity is simply
a matter of reversing the positions where two of
the incoming power source wires are connected
inside the control box.
NOTICE
If this machine is wired out-of-phase, the
motor and impeller will spin in the wrong
direction. The efficiency of the dust collector will be greatly reduced and will not
provide the rated CFM. You must make
sure the motor is spinning in the correct
direction before placing the machine into
full operation. Perform Step 10 of the test
run on Page 34 to make sure the machine
is correctly wired.
3. Secure the control box cover, then re-connect
the machine to power.
4. Perform Step 10 of the test run on Page 34
to confirm that the power connections are
correct.
— If the motor and impeller are still rotating
in the wrong direction, contact our Tech
Support at (570) 546-9663 for assistance.
To correct phase polarity:
1. DISCONNECT MACHINE FROM POWER!
2. Open the control box and swap the connec-
tions of any two incoming hot wires from the
power source (see Figure 9).

Refer to the Machine Data Sheet for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the maintenance and service described in this manual.
See below for required space allocation.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.
The physical environment where the machine is
operated is important for safe operation and longevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20–95% (non-condensing); or the
environment is subject to vibration, shocks, or
bumps.
Electrical Installation
Make sure all power cords are protected from
traffic, material handling, moisture, chemicals,
or other hazards. Make sure to leave access to
a means of disconnecting the power source or
engaging a lockout/tagout device, if required.
Lighting
Lighting around the machine must be adequate
enough that operations can be performed safely.
or impede the operator must be eliminated.

Mounting to Shop Floor
Mounting to Shop
Floor
Since your dust collector will be hardwired to the
power source, we strongly recommend securing your machine to the floor. Consult with your
electrician to ensure compliance with applicable
codes. Because floor materials may vary, floor
mounting hardware is not included.
Bolting to Concrete Floors
Lag shield anchors with lag bolts and anchor
studs (Figure 16) are two popular methods for
anchoring an object to a concrete floor. We suggest you research the many options for mounting
your machine and choose the one that best fits
your specific application.
NOTICE
Anchor studs (see Figure 16) are stronger
and more permanent alternatives to lag
shield anchors; however, they will stick out
of the floor, presenting a tripping hazard if
you decide to move your machine.
Assembly
To assemble the dust collector:
3
1. Use (8)
washers, and (8)
2 upper stand legs, 1 upper stand brace, and
1 lower stand brace —only finger tighten the fasteners (see Figure 17).
Note: To make the installation of the fasten-
ers easier, use scrap wood to raise the metal
components off the floor.

When using power lifting equipment during the assembly, make sure the equipment
is safe, fully operational, and adequately
rated for the weight being lifted. The operator of the equipment must be experienced
and able to use safe methods during these
processes. Failure to heed these warnings
could result in serious personal injury or
death.
6. Place the intake cylinder on the floor and
apply the 3 x 6 x 1800mm gasket to the
intake cylinder top rim, between the mounting
holes and the inside edge (see Figure 20).

4. Place the level across a corner of the lower
stand braces and move the upper stand
around until that corner is level, then fully
tighten all of the fasteners for that corner (see
Figure 19).

8. Use the (6) 5⁄16"-18 x 3⁄4" hex bolts and (6) 5⁄16"
flat washers to secure the intake cylinder to
the bottom of the blower housing (see Figure
21).
11. With assistance, place the intake barrel over
the large cyclone funnel and align the mounting holes as illustrated in Figure 22.
Note: Because this part of the dust collector
is not accessible after assembly, consider
using Medium Strength Blue Thread Locker
(Grizzly Model T21854) on the bolts that
secure the intake cylinder to the motor/blower
housing assembly to ensure that the fasteners won't come loose with vibration.

Due to the complexity required for planning,
bending, and installing the conduit necessary
for a code-compliant hardwire setup, an electrician or other qualified person MUST perform
this type of installation. Hardwire setups typically
require power supply wires to be enclosed inside
of a solid or flexible conduit, which is securely
mounted at both ends with the appropriate conduit fittings. All work must adhere to the required
electrical codes.
The hardwire setup for this machine must include
a locking disconnect switch (see Figure 51)
between the power source and the machine. This
switch serves as the means to completely disconnect the machine from power to prevent electrocution accidental startup during adjustments,
maintenance, or service to the machine.

Test Run
When the assembly is complete, test run your
dust collection system to make sure it operates
properly.
If, during the test run, you cannot easily locate
the source of an unusual noise or vibration, stop
using the machine immediately, then review the
Troubleshooting on Page 50.
If you still cannot remedy a problem, contact our
Tech Support at (570) 546-9663 for assistance.
To test run your dust collection system:
1. Make sure you have read the safety instruc-
tions at the beginning of the manual and that
the machine is setup properly.
2. Make sure all tools and objects used during
setup are cleared away from the machine.
3. Review Power Supply on Page 12 and con-
nect the machine to the power source.
5. Press the ON/OFF button to turn the machine
ON. Make sure your hand stays poised over
the switch in case you need to quickly turn
the machine OFF.
6. Listen to and watch for abnormal noises or
actions. The machine should run smoothly
with little or no vibration or rubbing noises.
— If you suspect any problems, immedi-
ately turn the machine OFF and disconnect the machine from power. Refer to
Troubleshooting on Page 50 to identify
and fix any problems.
—If you cannot solve the problem with the
use of the Troubleshooting guide, contact
our Tech Support at (570) 546-9663 for
assistance.

9. Toggle the ON/OFF button on both the con-
trol box and the remote control to make sure
they are working properly.
Note: For proper operation, the impeller
inside the blower housing must be rotating
counterclockwise. Since the motor and impeller are directly connected, you will verify in
the next step that the motor is rotating in the
correct direction.
Keep in mind that if the motor is rotating in
the incorrect direction, the dust collector will
still operate but with drastically reduced performance.
If any part of your body contacts the spinning impeller, severe cutting or amputation
injuries could occur. Always keep well away
from the impeller and never use any tools
near the impeller when the machine is connected to power.

SECTION 4: DESIGNING THE
You have many choices regarding main line and
branch line duct material. For best results, use
metal duct for the main line and branch lines, then
use short lengths of flexible hose to connect each
machine to the branch lines.
Plastic duct is also a popular material for home
shops. However, be aware that there is a fire or
explosion hazard if plastic duct material is used
for dust collection without being grounded against
static electrical charge build-up. This topic will be
discussed later in this section. Another problem
with using plastic is that it is less efficient per foot
than metal.
electrical buildup that can
The popularity of plastic duct is due to the fact
that it is an economical and readily available
product. It is also simple to assemble and easily
sealed against air loss. The primary disadvantage
of plastic duct for dust collection is the inherent
danger of static electrical build-up.
SYSTEM
General
Always guard against static electrical build up by
grounding all dust collection lines.
The Model G0637/G0638 is designed to be a central dust collector system. Install the dust collector
in an out of the way location such as a corner
or separate room. The large suction capacity of
the Model G0637/G0638 allows great flexibility
in planning and designing of your dust collection
duct layout. Grizzly offers a complete line of dust
collection accessories for setting up a stationary
system. Additionally, Grizzly offers a complete
guide book titled Dust Collection Basics.
Whatever system design you choose, always
make sure there are no open flames (including
pilot lights) in the same room as the dust collector; otherwise you risk an explosion if dust is
dispersed into the air.
Duct Material
Plastic duct generates static
cause fire or shock. Properly
ground it to reduce this risk.

There are a number of options when it comes to
metal duct, but metal duct that is specially manufactured for dust collection is the best choice.
When selecting your metal duct, choose high
quality metal duct with smooth welded internal
seams that will minimize airflow resistance. This
type of duct usually connects to other ducts
or elbows with a simple, self-sealing clamp, is
very quick and easy to assemble, and can be
readily dismantled and re-installed. This is especially important if you ever need to change things
around in your shop or add more tools.
Avoid inferior metal duct that requires you to cut it
to length and snap it together. This type of duct is
time consuming to install because it requires you
to seal all the seams with silicone and screw the
components on the ends with sheet metal screws.
Another disadvantage is the rough internal seams
and crimped ends that unavoidably increase static
pressure loss.
There are also many kinds of pure plastic flexible
hose, such as non-perforated drainage type hose
and dryer vent hose. Drainage type hose, while
being economical, does not quite have the flexibility required for dust collection. The inside of the
duct is also deeply corrugated and can increase
the static pressure loss by as much as 50% over
smooth wall duct. Dryer vent hose, while being
completely flexible, is non-resistant to abrasion
and has a tendency to collapse in a negative
pressure system. We DO NOT recommend using
dryer vent hose in your dust collection system.
If using flex-hose, you should choose one of the
many types that are designed specifically for the
movement of solid particles, i.e. dust, grains,
and plastics. However, the cost of specifically
designed flexible duct can vary greatly. Grizzly
offers polyethylene hose, which is well suited for
the removal of particulate matter, especially sawdust, since it is durable and completely flexible.
Polyethylene is also very economical and available in a wide variety of diameters and lengths for
most applications.
Flexible hose is generally used for short runs,
small shops and at rigid duct-to-tool connections.
There are many different types of flex hose on
the market today. These are manufactured from
materials such as polyethylene, PVC, cloth hose
dipped in rubber and even metal, including steel
and aluminum.
The superior choice here is metal flex hose that is
designed to be flexible, yet be as smooth as possible to reduce static pressure loss.
Metal Duct
Advantages of metal duct is its conductivity and
that it does not contribute to static electrical
charge build-up. However, static charges are still
produced when dust particles strike other dust
particles as they move through the duct. Since
metal duct is a conductor, it can be grounded quite
easily to dissipate any static electrical charges.

components.

System Design
For most small-to-medium sized shops, you can
design and build the dust collection system yourself without hiring engineers or consultants. We
have included some basic information here to get
you started on a basic design.
If you have a large shop or plan to design a complicated system, we recommend doing additional
research beyond this manual or seeking the help
of an expert.
When designing a successful dust collection system, planning is the most important step. In this
step, sketch a basic layout of your shop, including
space requirements of different machines.
Before you get out your pencil and paper, we recommend you visit our FREE

Our
and easily design and print a basic shop layout.
Don't worry, non-Grizzly brand machines can be
substituted with Grizzly machines for layout purposes.
After you're finished, make sure to
save your layout for later modification.
Your sketch only needs the basic details of the
shop layout, similar to
ing all your current/planned machines and your
planned placement of the dust collector
For the next step, sketch how you will connect
your machines to the dust collector. Consider
these general guidelines for an efficient system:

and less costly it will be.
Since each machine produces a different amount
of sawdust, the requirements for the minimum
amount of CFM to move that sawdust is unique
to the machine (for example, a planer produces
more sawdust than a table saw). Knowing this
required CFM is important to gauging which size
of duct to use.
Refer to the
below for a close estimation of
the airflow each machine requires. Keep in mind
that machines that generate the most sawdust
should be placed closest to the dust collector.
If the machine has multiple dust ports, the total
CFM required is the sum of all ports.
If the machine does not have a built-in dust port,

to determine which size of
dust port to install.

Determining Main Line Duct Size
The general rule of thumb for a main line duct is
that the velocity of the airflow must not fall below
3500 FPM.
For small/medium sized shops, using the inlet size
of the dust collector as the main line duct size
will usually keep the air velocity above 3500 FPM
and, depending on your system, will allow you to
keep multiple branches open at one time.
Mark your drawing, as shown in the
below,
but using the inlet size for your dust collector as
the main line.
The general rule of thumb for a branch line duct is
that the velocity of the airflow must not fall below
4000 FPM.
For small/medium sized shops, using the dust
port size from the machine as the branch line duct
size will achieve the correct velocity in most applications. However, if the dust port on the machine
is smaller than 4", make the branch line 4" and
neck the line down right before the dust port.
Note: Systems with powerful dust collectors work
better if multiple blast gates are left open. This
also allows you to run two machines at once.
Experiment with different combinations of blast
gates open/closed to find the best results for your
system.
Write your determined branch line sizes on your
drawing, as shown in the following figure.
If two machines will connect to the same branch
line and both will operate at the same time, then
add the required CFM for each machine together
and
to determine the correct branch size
If both machines will never run at the same time,
reference the machine with the biggest dust port
in the table

Adding duct work, elbows, branches and any
other components to a duct line increases airflow
resistance (static pressure loss). This resistance
can be minimized by using rigid (smooth) pipe and
gradual curves, as opposed to flexible pipe and
90˚ elbows.
To help you think about this resistance, imagine
riding a bicycle in a tunnel that is an exact replica
of your duct work. If the inside of the tunnel is very
bumpy (flexible pipe) and has a lot of sharp turns
(90˚ elbows), it will take a lot more effort to travel
from one end to the other.
The purpose of calculating the resistance is to
determine if it is low enough from the machine to
the dust collector to meet the given CFM requirement for the machine. Use the
to
calculate the resistance of duct work.
Planning Drop Downs
Plan the drop downs for each machine, using
blast gates wherever possible to control airflow.
In most small/medium shops it is only necessary
to calculate the line with the longest duct length or
the most fittings (operating under the assumption
that if the line with the highest resistance works,
the others will be fine).
To calculate the static pressure of any given
line in the system, follow these steps:
Curve is illustrated in Figure 73. Find 4.4 on
the Static Pressure axis (the amount of total
static pressure loss calculated in Figure 72),
then refer to the closest value on the CFM
axis—approximately 1120 CFM.
The 1120 CFM for the static pressure loss of
the line connected to the router is well above
the 220 CFM requirement of that machine.

System Grounding
Since plastic hose is abundant, relatively inexpensive, easily assembled and air tight, it is a
very popular material for conveying dust from
woodworking machines to the dust collector. We
recommend using flexible hose (flex-hose) to
connect the woodworking machine to the dust
collector. However, plastic flex-hose and plastic
duct are an insulator, and dust particles moving
against the walls of the plastic duct create a static
electrical build up. This charge will build until it
discharges to a ground. If a grounding medium
is not available to prevent static electrical build
up, the electrical charge will arc to the nearest
grounded source. This electrical discharge may
cause an explosion and subsequent fire inside
the system.
To protect against static electrical build up inside
a non-conducting duct, a bare copper wire should
be placed inside the duct along its length and
grounded to the dust collector. You must also
confirm that the dust collector is continuously
grounded through the electrical circuit to the electric service panel.
If you connect the dust collector to more than one
machine by way of a non-conducting branching
duct system and blast gates, the system must still
be grounded as mentioned above. We recommend inserting a continuous bare copper ground
wire inside the entire duct system and attaching
the wire to each grounded woodworking machine
We also recommend wrapping the outside of all
outside of the system against static electrical build
in your electric service panel.
Be sure that you extend the bare copper wire
down all branches of the system. Do not forget
to connect the wires to each other with wire nuts
when two branches meet at a “Y” or “T” connection.
Ensure that the entire system is grounded. If using
plastic blast gates to direct air flow, the grounding wire must be jumped (see the figure
below)
around the blast gate without interruption to the
grounding system.

SECTION 6: OPERATIONS
Operation Safety
Damage to your eyes, lungs, and ears could
result from using this machine without
proper protective gear. Always wear safety
glasses, a respirator, and hearing protection
when operating this machine.
Do NOT put hands or
small objects near inlet
openings during operation. Objects sucked
into the inlet will meet
with the impeller blade.
Failure to heed this
warning could result in
property damage or personal injury.
NOTICE
If you have never used this type of machine
or equipment before, WE STRONGLY RECOMMEND that you read books, trade magazines, or get formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will
not be held liable for accidents caused by
lack of training.
General
Operating your Model G0637/G0638 is simple
and straightforward. Blast gates located at each
of the machines controls the air flow from the
woodworking machine to the dust collector. If a
machine is not being used, keep the blast gate
closed to maintain higher levels of efficiency
throughout the system.
Remote Control
The remote control for the Model G0637/G0638
is IR (infrared) rather than RF (radio frequency) to
prevent accidental startups by other common RF
items like garage door openers.
DO NOT use the dust collector for any
other purpose besides collecting dust from
connected woodworking machines. A dust
collector should NEVER be used as a shop
vacuum and IS NOT a substitute for an air
filter system. For safest use, wear a respirator and use an air cleaner in addition to the
dust collector.
-46-
Because this remote system is IR, the remote
control must be pointing directly at the control box
with an unobstructed line-of-sight view.
If you place your dust collector in a different room
or outside of your shop, you must mount the switch
in the shop and wire it through the wall to the dust
collector to make use of the remote control.

SECTION 7: MAINTENANCE
Cleaning Filters
Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious personal injury.
The Model G0637/G0638 dust collector has a
gentle brush system inside the canisters for
removing any built-up dust from the filter pleats.
Schedule
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Daily Check:
• Dust collector is completely powered down at
the end of use.
• Dust collection drums and bags.
• Loose mounting bolts.
• Pressure leaks.
• Worn or damaged wires.
• Any other condition that would hamper the
safe and efficient operation of this machine.
Emptying Drums
Empty the collection drums when they are 3⁄4 full
or less. If the drums become overfilled, the dust
will be sucked into the intake barrel and passed
through to the canister filters.
How quickly the drum will fill up is based on the
type of work being done at the time:
•Fine dust from a sander or table saw will
slowly fill the drums.
To avoid damage to your
eyes and lungs, always
wear safety glasses and
a respirator when working
with the dust collection
bags.

the way, then pull the black handles down and
hook them in place.
Note: Always make sure to leave the red handles
in the up position to ensure that the brushes return
to their proper position and do not restrict the filter.
• Curly shavings from a planer or jointer will
quickly fill the drums.
In the beginning, check your drums regularly to get
an idea of how often they need to be emptied.

Rinsing Filter
For a thorough cleaning, the filter can be removed
and rinsed off. However, make sure to clean the
filter with the brush system first. Allow the filter to
air dry, but never leave the filter in the sun to dry
or it could become damaged.
Removing/Replacing
Filter
The filter for canister filter assemblies manufactured since November, 2009, can be removed
from the assembly so that it can be replaced or
rinsed off (see the instructions in the next subsection).
Removing/installing the filter requires removing
the canister filter assembly from the dust collector and disassembling it. Follow the instructions
below to perform this procedure.
3. Pull the black handle all the way down and
secure the cable into the handle hook at the
bottom of the canister assembly, as shown in
Figure 89, to hold it in place during the following steps.

Dust Collector Operation
SymptomPossible CausePossible Solution
Loud, repetitious
noise, or excessive
vibration coming
from dust collector.
Dust collector does
not adequately
collect dust
or chips; poor
performance.
Sawdust being
blown into the
air from the dust
collector.
1. Dust collector is not on a flat surface and
wobbles.
2. Impeller is damaged and unbalanced.
3. The motor mounting or housing
connections are loose.
4. Impeller is loose on the motor shaft.
5. Motor fan cover is dented, causing the
motor fan to hit the cover while spinning.
1. Dust collection bags are full.
2. Filter is dirty.
3. There is a restriction in the duct line.
4. The dust collector is too far away from
the point of suction, or there are too many
sharp bends in the ducting.
5. The lumber is wet and dust is not flowing
through the ducting smoothly.
6. There is a leak in the ducting, or a series
of small leaks, or too many open ports.
7. There are not enough open branch lines at
one time, thereby causing a velocity drop
in the main line.
8. The ducting and ports are incorrectly
sized.
9. The machine dust collection design is
inadequate.
10. The dust collector is too small for the dust
collection system.
1. Duct clamps or dust collection bags are
not properly clamped and secured.
2. Cylinder or funnel seals are loose or
damaged.
