Chapter 3: Getting Started Removing the Shipping Skid ) LEAVE THE FUME HOOD ATTACHED TO ITS SHIPPING SKID UNTIL IT IS AS CLOSE TO ITS FINAL LOCATION AS POSSIBLE. MOVE THE UNIT BY USING A SUITABLE FLOOR JACK, OR BY PLACING A FURNITURE DOLLY UNDERDNEATH THE SKID. DO NOT MOVE THE HOOD BY TILTING IT ONTO A HAND TRUCK. After you verify the fume hood components, move your hood to the location where you want to install it. Then, follow the steps listed next to remove the shipping skid from your unit.
Chapter 3: Getting Started Follow the instructions as shown in Figures 3-1, 3-2, and 3-3 3. 4. 1. Remove and discard the cardboard corner posts (Figure 3-1). 2. Remove strap that secures sash. For A-Style combination sashes disassemble from skid and attach to hood per Step 7. Remove the access panels and after removal, save the access panels and hardware for re-attachment.
Chapter 3: Getting Started Install the Protector ClassMate Hood on A Supporting Structure and Work Surface ! The Protector ClassMate is heavy! Use caution when lifting or moving the unit. When installing the Protector ClassMate Fume Hood onto a chemically resistant work surface or benchtop, ensure that the structure can safely support the combined weight of the fume hood and any related equipment.
Chapter 3: Getting Started The following are instructions for mounting a 2 x 4 cross support: 1. Level the base cabinets and the work surface. 2. Scribe a line on the wall or back of the base cabinet to locate the support under the work surface. 3. Mount the support by attaching it to the wall or base cabinet. 4. Place the hood on top of the work surface and cross support. The work surface should be smooth and durable, and made from a chemically resistant epoxy resin.
Chapter 3: Getting Started Figure 3-5 The exhaust connection should be installed by a qualified HVAC contractor.
Chapter 3: Getting Started The exhaust connection on your hood has been designed for 8" nominal pipe (8.62" O.D.) to allow for minimum static pressure loss with proper transport velocities away from the hood. It is acceptable to combine the air from two back to back hoods with a 12" x 8" x 8" dual exhaust adapter that would basically have two 8" nominal exhaust inlets and one 12" (12.00" O.D.) nominal exhaust outlet. See Appendix D: Protector ClassMate Accessories for dual exhaust adapter.
Chapter 3: Getting Started The identification plate, model number, serial number, and electrical connection boxes are accessible from the front of the fume hood by removing the front panel. The remote blower style Protector ClassMate Hood is fully wired internally for 115 Volt, 60 Hz, 15 Amp electrical service. The number of circuits varies depending on the model. The Protector ClassMate Hood models do not feature internal wiring or electrical components excluding the fluorescent light assembly.
Chapter 3: Getting Started The fluorescent light has been mounted outside the top liner panel assembly and is sealed from any vapors used inside the hood structure. To change the fluorescent light bulbs in your hood, you must first remove the front panel from the hood. Next remove the screws holding down the light reflectors. Remove the light reflectors and slide them away temporarily. The fluorescent light assembly is now fully exposed and ready for service.
Chapter 3: Getting Started Figure 3-8 To install the supply tubing, follow these steps: 1. Remove the valve service plate and outlet fitting access covers by loosening their individual screws. The valve body and service areas will now be fully exposed. 2. Ensure that the tubing is ¼ inch outside diameter, soft metal, and that the end has been deburred completely. (See Appendix D Service Fixture Accessories to order 5.5' of supply tubing 48899-00 or 49211-00 gas). 3.
Chapter 3: Getting Started 7. Close the service valve in the Protector ClassMate Fume Hood and then slowly open the shutoff valve on the service line. ! NOTE: Inspect all fittings for leakage. Tighten the tube nut slightly if needed. ! CAUTION: Do not use oxygen with service fixtures as supplied with this hood. Contact Labconco for oxygen fixture information.
Chapter 3: Getting Started walls of the hoods. Materials such as silicone sealants may be used to seal the hood structure. Certifying the Protector ClassMate Fume Hood The combination of your laboratory hood, exhaust ductwork, and exhaust blower enables you flexibility to change the airflow generated across the sash opening on the hood. To determine the actual face velocity through the sash opening, airflow velocity readings will need to be taken.
Chapter 3: Getting Started Your Protector ClassMate Fume Hood has been certified at the factory per ASHRAE 110-1995. In this procedure Labconco tests the “as manufactured” hood for average face velocity readings, smoke visualization, and tracer gas containment readings less than 0.1 part per million (PPM) with a mannequin. For “field use” ASHRAE testing contact Labconco Sales Engineering Team for a certified on-site contractor.
CHAPTER 4 THEORY OF OPERATION AND SAFETY PRECAUTIONS Theory of Operation: The Protector® ClassMate Laboratory Hood is designed to meet the needs of the science instructor. Clear back and sides and taller front viewing window provide enhanced visibility for the instructor conducting chemistry demonstrations or observing students using the hood. The ergonomic inclined front promotes additional visibility into the laboratory.
Chapter 4: Theory of Operation and Safety Precautions behind the front and under the airfoil to help control fluctuations in face velocity, which occur as the sash is closed. The major components in Protector ClassMate Laboratory Hoods are outlined as follows and in Figure 4-1, and Figure 4-1A: 1. Clear, tempered safety glass sides, back and baffle provide maximum visibility. All glass components except sashes are removable for cleaning. Visibility up to 45" on sides and back. 2.
Chapter 4: Theory of Operation and Safety Precautions wired light is serviceable from outside the hood cavity. 11. Low mounted, factory wired light and blower switches are ADA compliant. 12. Ergonomic airfoil allows air to sweep work surface for maximum containment and provide a Patented Clean Sweep™ on the upper surface to provide maximum containment. 13. Low profile trough below airfoil contains spills. The trough is the same depth as the work surface (1.25") and requires no cabinet overhang. 14.
Chapter 4: Theory of Operation and Safety Precautions different heights and still maintain the same visual accessibility. The 4' hoods have a single vertical rising sash; 5' and 6' hoods have combination horizontal sliding/vertical rising sashes. These combination sashes allow the operator to use the hood with sashes either half open vertically or horizontally to conserve energy.

Chapter 4: Theory of Operation and Safety Precautions Figure 4-1A 32 Product Service 1-800-522-7658
Chapter 4: Theory of Operation and Safety Precautions Safety Precautions ! ) Although the laboratory hood has been engineered to maintain optimum operator safety, caution should always be used while working in the hood. Prior to using the hood, check to make sure that the exhaust blower is operating and that air is entering the hood at the proper velocity of 100 fpm. USE GOOD HOUSEKEEPING IN THE HOOD AT ALL TIMES. CLEAN UP SPILLS IMMEDIATELY.
Chapter 4: Theory of Operation and Safety Precautions BLOCKS ARE LEVEL AND SET IN PLACE. ! Blocking the bottom of the baffle at rear of hood will change the airflow pattern in the hood causing turbulence and possible leakage at the face of the hood. (Don’t store containers or supplies against baffles, as this will affect airflow through the hood). Avoid placing head inside hood. Keep hands out of hood as much as possible. Always work as far back in hood as possible.
Chapter 4: Theory of Operation and Safety Precautions CREATED MAY DRAW FUMES OUT OF THE HOOD. ! The use of heat generating equipment in this hood without the exhaust system operating properly can cause damage to the hood. The Protector ClassMate Laboratory Hood should be certified by a qualified certification technician before its initial use. The hood should be recertified whenever it is relocated, serviced or at least annually thereafter.

CHAPTER 5 USING YOUR PROTECTOR CLASSMATE FUME HOOD Operating the Vertical Rising Sash S Because of the Protector ClassMate's counterbalanced, anti-racking 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 sash may be raised from a closed to 18" operating height where it bumps the sash stop.
Chapter 5: Using Your Protector ClassMate Fume Hood Figure 5-1 A Operating the A-Style Combination Sash Some hood models have additional energy saving sashes called A-Style Combination Sashes in place of vertical-rising and pivoting sashes. These combination sashes allow the operator to use the hood with sashes either half open horizontally or vertically to conserve energy. The horizontal sashes are used in normal operating mode.
Chapter 5: Using Your Protector ClassMate Fume Hood Figure 5-2 Combination Sash Typical Sash Stop Horizontal Sash Operating the Blower S A Your Protector ClassMate Fume Hood utilizes a remote style blower, which can be activated from the blower switch by turning the blower switch to “ON”.
