CS
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.
Connect to the Blower Inlet for Coated Steel Blowers
Coated Steel Blowers model numbers 7068000 through 7068700, feature a 10-7/8" ID by 1-1/2" wide circular inlet ring. This inlet ring is suitable for use with 10-inch diameter PVC ductwork. The PVC ductwork itself will fit inside the inlet ring and should be fastened by sheet metal screws through the inlet ring. A silicone sealant should also be used to seal between the ductwork and the blower inlet ring to prevent any air or moisture leakage.

Chapter 3: Getting Started
!
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 codes may require that a circuit disconnect, overload protection, and short circuit protection be included in the installation. Please consult the code or have the unit 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.
