Removing these fasteners allows you to rotate the housing
to one of the other desired outlet positions. Then insert the
8 fasteners and secure the blower housing in that specific
position.
3. Reinstall the upper weathercover panel and you are ready
for operation.
CAUTION: Blower 7071900 must be installed
with outlet positioned for upward discharge.
This will ensure that the integral back draft
damper assembly will work properly. The
dampers close by gravity when the blower is
turned off and the blower needs to be in the
proper orientation for this to occur.
Install the Exhaust Run with
Vibration Dampers
Rubber isolation sleeves should be used in your exhaust duct run
prior to entering the blower inlet. These isolation sleeves dampen
vibration that is being generated by the blower and decrease noise
level at the fume hood. See the flexible duct connections listed in
Chapter 7.

!
wire directly to the exposed terminals inside the motor. A
knockout has also been provided on the side of the motor for this
purpose.
Access the motor by removing the top weathercover of the blower
base. This weathercover is held in position by machine screws,
and once they have been removed, you will have access to both the
motor and V-belt area of your blower.
CAUTION: Inspect the motor manufacturer’s
nameplate carefully prior to connecting your
electrical service for both the correct lead wire
orientation and motor rotation.
The blower base end panel is raised off the blower base to allow
for a continuous flow of cooling air through the motor cavity.
Slots and louvers have also been placed on both the front and back
of the blower base to provide airflow through this motor cavity.
Because the blower base end panel is shorter than the rest of the
base assembly, you will be able to run your electrical conduit
directly underneath this panel. No special cutouts or modifications
are necessary.
Three Phase Power
Most all Labconco Fume Hoods have a simple single-wire switch
for controlling single-phase power to a motor/blower. When a 3phase motor is required, all 3 phases must be switched ON or OFF.
To do this, the Labconco single wire switch can be used to control
a power relay (also called a contactor or motor starter), which uses
the switched Labconco power to control the switching ON (or
OFF) of all three phases at once. The drawing on the following
page shows such a setup.

CAUTION: This blower contains
an electrical motor, which requires
proper electrical connection per
the National Electrical Code
(NEC) Section 430 to prevent
hazards. This NEC code and local

connected by a licensed electrician.
Install the Belt, Adjust the Fan
Speed and Confirm the
Performance of your
Blower/Hood System
Labconco Exhaust Blowers leave the factory adjusted to their top
speed with the belt uninstalled. Frequently, they need to be
readjusted in the field to allow the hood to operate at the proper
face velocity, and to bring the motor current into its proper range.
In order to adjust the blower to the proper speed and install the
belt, refer to the diagrams in Appendix A Replacement Parts, and
follow the procedure below.
1. Ensure the blower is turned off at the roof disconnect.
2. Remove the top weather cover over the motor/drive
compartment.
3. Raise the gravity belt tightener, and remove the belt, tie
wraps, and cardboard under the motor. If no adjustment is
required then proceed to step 7.
4. Loosen the setscrew, with a standard hex key, on the outer
half of the adjustable sheave located on the motor shaft.
5. While holding the back half of the adjustable sheave, turn
the front half of the sheave counter-clockwise to widen the
space between the two halves of the sheave. This creates a
smaller sheave diameter, which lowers the fan speed.
There are a maximum of four turns of adjustment. Do not
allow the belt to ride down on the threaded mandrels of the
sheave.
16
Chapter 3: Getting Started
Product Service 1-800-522-7658, International 816-333-8811
6. Once the sheave is adjusted to the correct spacing, secure
the set screw on the front half of the sheave.
7. Raise the motor up on the gravity belt tightener, and re-
install the belt on both sheaves.
8. Turn the blower back on at the roof disconnect.
9. Check the motor current with an ammeter to ensure it is in
its proper operating range. Consult Chapter 4 for amperage
specifications for your particular model.
10. Verify the hood face velocity is in its proper range. This
should be done across the sash opening of the hood in
accordance with the “Industrial Ventilation Manual”
section on laboratory hoods. Labconco recommends an
average face velocity of 60, 80, or 100 feet per minute.
Consult Labconco for proper airflows for your particular
model.
11. Replace the weather cover over the motor/drive
compartment.

NOTE: FOR A COMPLETE PERSPECTIVE
AND EXPLODED VIEWS OF YOUR
PARTICULAR BLOWER, REFER TO APPENDIX
A REPLACEMENT PARTS.
Safety Precautions
Before attempting any service and/or
maintenance on your blower, always disconnect
the blower motor from its power source to
prevent possible injury. Upon initial start-up,
always wear protective eyewear. A qualified
technician should certify the blower/hood system
before it is initially used. The blower/hood
system should be re-certified annually or
whenever it is relocated.
29
Product Service 1-800-522-7658, International 816-333-8811
CHAPTER 5
USING YOUR BLOWER
Normal Operation
Once your blower has been fully ducted and electrically wired, it is
ready for operation. The blower is normally activated from a
switch on or near the fume hood.
Laboratory work can resume when the blower is operational, so
that any prevailing fumes and/or odors can be exhausted from the
room. Work must cease prior to turning the blower off.

CHAPTER 6
MAINTAINING YOUR
BLOWER
Now we will review the suggested maintenance schedule and the
common service operations necessary to maintain your blower for
peak performance.
Only trained and experienced certification
technicians should perform some of the service
operations after the blower has been properly
decontaminated. The wrench icon precedes the
service operations that require qualified
technicians.
Routine Maintenance
CAUTION: Before attempting any service
and/or maintenance on your blower, always
disconnect the unit from its power supply source.
32
Chapter 6: Maintaining Your Blower
Product Service 1-800-522-7658, International 816-333-8811
Motor
Under normal usage, the drip proof style motor will require that
you add 3-4 drops of SAE 10 motor oil to each oil port on the
motor after 25,000 hours of operation. Should your blower motor
experience constant use, maintenance should be on an annual
basis, to extend the life of the blower motor.
Bearings
The pillow block bearings on your blower are factory sealed and
lubricated. Under normal operation, no further lubrication is
required. Excessive lubricating may cause damage to the bearing
seal and significantly shorten the life span of the bearing.
V-Belt
The drive belt on the blower should be inspected on a monthly
basis for excessive wear. Fraying of the belt would indicate
possible misalignment of the blower’s sheaves.
The gravity belt tightener, incorporated into your blower assembly,
extend the life of the V-belt if properly adjusted. If you need to
replace the belt, remove the upper weathercover and lift up on the
motor. The belt should be replaced a minimum of once every four
years.
Common Service Operations (See
drawings in Appendix A
Replacement Parts)
Pillow Block Bearing Replacement
If you need to replace a pillow block bearing on your blower, make
sure that the locking collars on the bearings face one another. The
setscrews used on the locking collars have been sealed with a
removable thread sealant. Thread sealant should be applied when
a pillow block bearing is replaced in the field.
33

Chapter 6: Maintaining Your Blower
Motor Replacement
With the power disconnected, remove the upper weathercover, the
V-belt, the mounting hardware that supports the NEMA 56 motor
frame and remove the motor. Remove the wire leads to the motor
plate. Re-install the new motor in reverse order.

CHAPTER 7
MODIFYING YOUR
BLOWER, CALCULATING
STATIC PRESSURE
LOSS, AND BLOWER
SIZING
Two Main Blower Modifications
There are two main ways to modify the performance of your
blower as listed in Chapter 3: Getting Started. One way is the
adjustment of the blower outlet orientation. The other way is the
adjustment of the fan speed to fine-tune the performance of your
blower/hood system. Refer to Chapter 3 for these instructions.
Additionally, all the performance data for your particular blower
model number are listed in Chapter 4: Performance Data and
Safety Precautions.
Additional Modifications by Adding Ductwork Accessories
There are additional ways to equip your blower by adding any of
the accessories on the following pages. To ensure that your blower
exhaust system will operate properly, the ductwork and accessories
linking your hood and blower must be sized correctly. Along with
the accessories listed next are the “equivalent resistance in feet of
straight duct” for each accessory. It is necessary to compute the
sum of the equivalent resistance factors for each accessory and
36
Chapter 7: Modifying Your Blower
Product Service 1-800-522-7658, International 816-333-8811
ductwork length for your entire hood/blower system. Then the
blower can be sized properly from the total equivalent resistance
for your exhaust system. Blower Sizing Example: You have
selected a Labconco Protector Premier 48 Laboratory Hood at 100
fpm and 730 CFM. The static pressure of the Protector Premier 48
at 100 fpm is 0.17". The exhaust collar of this hood is sized to
receive 12" diameter PVC duct directly. In this example, your
fume removal system requires 30 feet of straight duct, two 90°
elbows and one zero pressure weathercap to adequately exhaust the
chemical fumes. You will be handling low to moderately
corrosive materials, so you have selected a Coated Steel Blower.
The information following for the 90° elbow tells you that each
90°, 12" diameter elbow has the equivalent resistance of 25 feet of
straight duct. The zero pressure weathercap has 5 feet of
equivalent resistance. The total equivalent feet for the system is:
Feet of straight duct 30 Feet
2 elbows @ 25 feet each 50 Feet
1 zero pressure weathercap @ 5 feet 5 Feet
85 Feet
The chart following converts “equivalent resistance in feet of
straight duct” to static pressure. So the static pressure of 85
equivalent feet of 12" nominal duct is equal to (85/10) x 0.011" =
0.094". Now this is added to the hood static pressure of 0.17" for a
total system static pressure of 0.264". Look at the performance
data in Chapter 4 for Coated Steel Blowers. Refer to the 0.25"
column at 730 CFM since this is closest to 0.264". The chart will
lead you to select a Coated Steel Blower model #7068800 or EP
Coated Steel Blower #7068900.
Sizes and Pressure Losses in Thermoplastic Duct
This chart provides static pressure losses for 10' long duct lengths
of various diameters over a range of airflows in CFM for use in
sizing hood/blower combinations at 100 feet per minute.

CONDITIONS
Environmental Conditions
Maximum altitude: 9843 feet (3000 meters).
Ambient temperature range: -30° to 130°F (-34° to 54°C).
Main supply voltage fluctuations not to exceed ±10% of the
nominal voltage.
Transient over-voltages according to Installation Categories
II (Over-voltage Categories per IEC 1010). Temporary
voltage spikes on the AC input line that may be as high as
1500V for 115V models and 2500V for 230V models are
allowed.
Used in an environment of Pollution degrees 2 (i.e., where
normally only non-conductive atmospheres are present).
Occasionally, however, a temporary conductivity caused by
condensation must be expected, in accordance with IEC
664.
