CAUTION See Manual. This symbol on the fume hood indicates the possibility of a pinch hazard. PRUDENCE Consulter le Manuel. Ce symbole sur la hotte indique la possibilité d’un risque de pincement.

Performance
The Basic Hood maximizes work area due to its unique single wall design. The hood is available with or without a blower and in both an assembled or unassembled configuration.

The hood features by-pass airflow design that promotes full containment as the sash is moved. Airflow is diverted to behind the front panel and under the sash foil to help minimize face velocity increases as the sash is lowered to the working position the operator chooses.

!

If the unit is not operated as specified in this manual it may impair the protection provided by the unit.

Si l’unité n’est pas utilisée comme spécifié dans ce manuel il peut diminuer la protection fournie par l’unité.

Component Identification

1. Sash Foil. The sash foil is located directly underneath the sash opening of the fume hood. The aerodynamic shape of the foil directs a smooth flow of air into the hood with minimum turbulence. The sash foil is also part of the air by-pass system on the hood, which allows a portion of the room air to flow under the foil and into the fume hood. The by-pass airflow feature promotes full containment as the sash is moved.
2. Adjustable Baffle. Epoxy-coated steel baffle features an adjustment slot to change the internal airflow patterns within the hood. The slot adjustment is regulated by loosening the baffle retaining knobs located directly on the baffle and then pushing the upper portion of the lower baffle inward to expose the slot opening in the baffle.
3. Tempered Safety Glass Sash. A vertical rising tempered safety glass sash assembly allows the hood operator the flexibility of positioning the sash at any suitable height for various procedures that he may perform within the fume hood.

Chapter 1: Introduction

Original instructions

4. Light Fixture. The hood interior is illuminated by a single vapor-proof incandescent light fixture. An explosion-proof incandescent light fixture is also featured on the explosion-proof models. Both light assemblies are suitable for use with a 100-watt light bulb.
5. Exhaust Connection. The hood features an epoxy-coated steel exhaust outlet ring sized to accept either the built-in motor/blower assembly or a ten-inch diameter plastic duct. When used with a remote blower, the exhaust duct slips down directly over the exterior of the exhaust connection. The duct is then attached directly to the exhaust connection ring using sheet metal screws and caulking. When the built-in motor/blower is used, the exhaust duct is connected directly to the exhaust connection on the blower itself. The ductwork should be secured to the blower by using sheet metal screws and caulking.

WARNING: The weight of the exhaust ductwork should be
! supported independently of the hood structure as excess weight could cause damage to the hood structure.
AVERTISSEMENT: Le poids des gaines d’échappement doit être pris en charge indépendamment de la structure de la hotte comme l’excès de poids peut causer des dommages à la structure de la hotte.

6. Blower Assembly (not shown). A fractional horsepower motor/blower assembly comes complete with a coated metal blower housing, exterior cover and aluminum impeller wheel. Depending upon your specific application or preference, the motor/blower assembly can be mounted directly in the top of the fume hood or located externally in your duct run or on the roof itself.

Chapter 2: Installation

Original instructions

The electrical wiring of your hood is dependent upon your exact model. Review the wiring diagrams for your specific hood located on pages 13 and 14 prior to installation. All wiring should be done in accordance with local and National Electrical Codes.
Le câblage électrique de votre hotte dépend de votre modèle exact. Passez en revue les schémas de câblage pour votre capot spécifique situé sur les pages 13 et 14 avant l’installation. Tout le câblage doit être fait conformément aux codes électriques locaux et nationaux.
If your hood is an explosion-proof model, it will not be internally wired. All wiring for the enclosure MUST be done by a licensed electrician and conform to all local codes. In most cases, the hood will require the use of conduit shielding to protect the wiring being brought into the hood and the grounding connection of the wiring shall be made in such a manner that the terminal box cover may be removed without disturbing the electrical connections.

Sash Weight Release
The sash weight has been secured in the sash weight tracks located on the back of your fume hood during shipment. The weight has been strapped to the bottom of the hood back panel through the use of two plastic wire ties. Cut and remove these ties to release the weight. Next, remove the cardboard packing material placed behind the weight for shipment. Then slide the sash weight up to the top position and attach the two sash cables directly into the slots provided on the weight to begin proper operation.

Chapter 2: Installation

Placing and Sealing the Fume Hood
The Basic Hood performs best with the front of the lower airfoil placed flush with the front of the work surface. Alternatively, the Basic Hood can be placed in front of the work surface by one inch. The Basic Hood lower airfoil shall not be placed behind the front edge of the work surface.

Once the Basic Hood has been set into position and all the plumbing and exhaust ducting has been completed, it should be sealed to its work surface. The sealing of the hood structure to the work surface will prevent any spilled materials from collecting underneath the walls of the fume hood. Silicone sealant is normally used for this purpose, and can be purchased locally or directly from Labconco.
Exhaust Connection for Hoods with Built-In Blower
The exhaust connection on your Basic Hood with built-in blower features a round exhaust outlet sized to accept ten-inch diameter PVC ducting. The exhaust duct size allows for a minimum of static pressure loss through the hood at normal face velocities and generates a sufficient transport velocity through the duct to safely exhaust the toxic materials being handled in the laboratory hood.

The exhaust duct used on this hood will be under positive pressure during operation. It is essential that all duct joints be sealed properly to eliminate the possibility of leaking exhaust contaminants into your laboratory.

WARNING: The weight of the exhaust duct system must be
! supported independently of the fume hood structure. Do not allow the weight to be supported by the hood structure as damage to the hood structure may result.

AVERTISSEMENT: Le poids du système de conduit d’évacuation doit être soutenu indépendamment de la structure de la hotte. Ne pas laisser le poids d’être supporté par la structure de capot d’endommager la structure de la hotte peut en résulter.

Exhaust Connection for Hoods with Remotely Located Blower
The exhaust connection on your Basic Hood, when not using the built-in blower, features a coated steel outlet ring connection sized to accept ten inch diameter PVC ducting. The exhaust duct size allows for a minimum of static pressure loss through the hood at normal face velocities and generates a sufficient transport velocity through the ducting to safely exhaust the toxic materials being handled in the laboratory hood.

CHAPTER 4 NORMAL OPERATION
Although the laboratory hood has been engineered to maintain the optimum in operator safety, caution should always be used while working in the hood. Good general housekeeping procedures with the following specific recommendations should allow you to operate your laboratory hood safely.
Do not overload the work surface with apparatus or work material. The safe operation of the laboratory hood is based upon having proper airflow through the structure.
Do not store containers or supplies against the baffle, as this will affect airflow through the hood. Blocking the bottom of the baffle will change the airflow pattern in the hood causing turbulence and possible leakage at the face of the hood.
Using flammable or explosive materials in this hood, unless it has been equipped with explosion-proof components, is not recommended.
Do not work with or store chemicals in this hood without operating the exhaust system.
Perchloric acid should not be used in this hood.
Radioisotope materials are not recommended for use in this hood.
The use of heat generating equipment in this hood without operating the exhaust system may cause damage to the hood liner.
Seal all duct joints properly to prevent the leakage of any exhaust contaminants from the duct.

Original instructions

Working in your Protector Fume Hood
Planning Thoroughly understand procedures and equipment required before beginning work. Arrange for minimal disruptions, such as room traffic or entry into the room while the hood is in use.
Start-up Labconco follows the recommendations of the American National Standard Institute with regards to fume hood exhaust systems. A full list of requirements can be found in the ANSI Standard No. Z9.5 Laboratory Ventilation. If you are unsure of the proper use of the exhaust blower for your fume hood, contact your safety officer or industrial hygienist before making any modifications to the
constant negative pressure is an excellent way to ensure hazardous fumes in the fume hood do not enter the laboratory space inadvertently.
Turn on the light. Slowly raise the sash and verify the fume hood has proper airflow. Check the baffle air slots for obstructions. Allow the hood to operate unobstructed for two minutes. Wear a long sleeved lab coat and rubber gloves. Use protective eyewear. Wear a protective mask if appropriate.
Loading Materials and Equipment Only load the materials required for the procedure. Do not overload the hood. Do not obstruct the front air foil (sill), or rear baffle slots. Large objects should not be placed close together and spaced above the work surface to permit airflow to sweep under the equipment. After loading the hood, wait one minute to purge airborne contaminants from the work area.
Work Techniques Keep all materials at least 6 inches inside of the sash and at least two inches from the side walls and perform all contaminated operations as far to the rear of the work area as possible. Keep all clean and contaminated materials in the work area separate for clear identification. Avoid using techniques or procedures that disrupt the airflow patterns of the hood.

APPENDIX B ROUTINE MAINTENANCE

The exhaust blower motor has been factory lubricated for two years of service. After this period 20 to 30 drops of SAE 20 automotive oil annually is sufficient. Reference the nameplate on the motor for additional oiling instructions.
Periodically check the belt tightness on the motor/blower assembly for proper adjustment.
The belt on the motor/blower has been factory set at a desired tension level. The tension on the belt can be measured by the amount of pressure exerted to deflect the belt 1/2″ from its normal position and this should be approximately 5 pounds.

APPENDIX C PERFORMANCE TESTING
Your Labconco laboratory hood has been designed to allow you the flexibility of setting your own face velocity based upon the work being performed inside of the hood. The combination of your laboratory hood, exhaust duct, and exhaust blower enables you to achieve this flexibility by regulating airflow across the sash opening. To determine the actual face velocity through the sash opening, airflow velocity readings will need to be taken. This should be done across the sash opening of the hood in accordance with the section on laboratory hoods in Industrial Ventilation.
