The number of circuits varies depending on the model. All of the electrical connections are terminated at the field wiring terminal box for hook-up by a qualified electrician. We recommend each circuit be a dedicated branch circuit. However, if wired together the maximum load allowed is the sum of individual outlets plus the rating of the unit (i.e. 2 Amps). The single point internal junction box is used for the connection of the lights, blower, and duplex outlets. Refer to the wiring diagram for your Protector XL in Appendix C: Protector Pass-Through Specifications.

The fume hood is required to be grounded to the MAINS protective earthing ground for safe operation. Using a ring terminal sized for a 10-24 machine screw, connect the MAINS ground conductor to the grounding lug marked with the protective

earthing symbol, . Only MAINS ground conductors should be connected to the protective earthing ground lug, no other conductors should be connected to this grounding lug. Using wire nuts connect the MAINS supply conductors to the fume hood supply wires. Insure that the wires are connected as per the appropriate wire color codes for the input voltage. For 115V Phase (Hot) is black and Neutral is white, for 230V Phase1 is brown and Phase2 is blue. Refer to the wiring diagram for your Protector XL in Appendix C: Protector Pass-Through Specifications.

Original instructions

CAUTION: Natural gas should be used only in the service fixture that has been pre-plumbed with brass tubing. Sulfur content of the gas could cause deterioration of standard copper supply lines.

PRUDENCE : Le gaz naturel devrait être seulement utilisé dans l'accessoire de service qui a été pré soudé avec des tuyaux de cuivre. Le contenu soufré du gaz pourrait causer la détérioration des lignes d’alimentation en cuivre standard.

Sealing the Protector Hood to the Work

Surface

When the hood has been set in place, ducted, wired, and plumbed, it should be sealed at the work surface to prevent spilled materials from collecting under the walls of the hood. Materials such as silicone sealants are recommended to seal the hood structure.

Certifying the Protector Fume Hood

The combination of your laboratory hood, exhaust ductwork, and exhaust blower gives you the flexibility to change the airflow at the sash opening of your hood. To determine the actual face velocity at 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 Industrial Ventilation Manual section on laboratory hoods (see Appendix E: References). For best containment on PassThrough Hoods, Labconco recommends an average face velocity at the sash opening of 100 feet per minute. Consult Chapter 2 for proper airflow volumes for your particular model.

Your Protector Fume Hood has been tested at the factory per ASHRAE 110-1995. All hoods achieve an “as manufactured rating” of less than 0.05 part per million (ppm) at 4 liters per minute (lpm); AM<0.05 (consult Labconco for individual fume hood ratings). For “field use” ASHRAE testing contact Labconco Sales Engineering Team or Customer Service for a certified on-site contractor.

NOTE: Face velocity profiles and smoke testing should be done periodically to ensure safe performance.

NOTE : Les profils de flux frontal et les tests de fumée devraient être régulièrement faits pour garantir une utilisation en toute securité.

CHAPTER 5

USING YOUR PROTECTOR

PASS-THROUGH

Operating the Vertical-Rising Sash

Because of the Protector Hood counterbalanced sash mechanism, it will take only a few pounds of force to move the sash up or down, and you can operate the sash smoothly with one or two hands positioned any where along the handle. The vertical-rising sashes may be raised to a maximum 28" operating height. The airflow requirements should be sized for the 28" operating height; if using sash stops then the airflow requirements can be reduced by approximately 40% at 18". See Chapter 2 for airflows.

Operating the Blower

Your Protector Fume Hood utilizes a remote style blower, which can be activated by turning the blower switch to “ON.” You can validate the hood performance by watching smoke drawn into the hood face opening.

Operating the Lights

Your Protector Fume Hood utilizes a factory-wired fluorescent light to illuminate the hood interior. Optional direct replacement LED T8 bulbs are available per Appendix A. Simply turn the light switch to “ON” to operate.

Chapter 5: Using Your Protector Pass-Through

Product Service 1-800-522-7658

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

blower’s operational status (on/off/low, etc.). Keeping the exhaust system under

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.

Chapter 5: Using Your Protector Pass-Through

Product Service 1-800-522-7658

Original instructions

Final Purging

 Upon completion of the work, the hood should be allowed to operate for

two minutes undisturbed, to purge airborne contaminants from the work area before closing the sash.

Unloading Materials and Equipment

 Objects in contact with contaminated material should be surface

decontaminated before removal from the hood.

 All open trays or containers should be covered before being removed from

the hood.

Shutdown

 Turn off the light and close the sash.

Appendix F: Disassembly & Reassembly Instructions

Product Service 1-800-522-7658

Original instructions

Sash Removal

There are two (2) sashes to be removed on the Pass-Through hoods. Please repeat the procedure for each sash.

1. Remove the sash end stop brackets by removing the two (2) #10-24 screws on each

end stop bracket. The sash cables are attached through these end stop brackets.

2. Now the glass sash assembly can be removed by sliding it up and out.

Note - Sash weights are mounted in retention tracks on one side of the PassThrough hood. They do not need to be removed to remove the sash(es). If sash weight removal is desired, see Chapter 3: Sash Weight Release.

Airfoil Removal

1. Remove lower corner post screw located under the airfoil.

2. Remove the airfoil by removing the rear screws located on top of the airfoil on each

side.

Transport and Reassembly

The various subassemblies are now ready to be transported and reassembled in the opposite way the hood was disassembled. All hoods will require a minimum of five people to lift the hood, two people on each side and one in front (for balance only). A hydraulic lift table should be used as an aid in lifting. If in doubt about lifting the hood, always reassemble the hood where it will be placed.

Sash Weight Reassembly

After the hood is assembled, the sash weights are easily installed before the hood is installed in a wall, because the wall may reduce access to the side panel and the sash weights behind the side panel. Please keep this in mind and install the sash weights

now. Hood Replacement and Service Installation

The hood is now ready for placement and the HVAC, plumbing and electrical service can be installed.
