Chapter 3: Getting Started 2. Find the hardware (bolts, washers, nuts) that attach the fume hood to the skid and remove the hardware. Some hardware is on the sides and some is on the back. Sash Weight Release To protect the fume hood from damage in shipment, the sash weight has been secured to the back of the fume hood with four (4) screws. Simply remove the screws and make sure the sash cables are on their respective pulleys before operation of the sash or damage could occur to the sash cable.
Chapter 3: Getting Started The work surface should be smooth and durable, such as a chemically-resistant epoxy resin. The surface should be nonporous and resistant to the acids, solvents, and chemicals used in conjunction with the Protector Fume Hood. The work surface should also contain a dished recessed area for containing primary spills.
Chapter 3: Getting Started The exhaust connection should be installed by a qualified HVAC contractor. The exhaust connection on your hood has been designed for 12" nominal pipe (12.75" OD) to allow for minimum static pressure loss with proper transport velocities away from the hood. Consult Labconco Customer Service should you require help sizing your blower for the exhaust volume and total system static pressure loss.
Chapter 3: Getting Started Internal Junction Box Figure 3-2 All wiring for the fume hood SHOULD be performed by a licensed electrician and conform to all local codes. In most cases, the hood will require the use of shielded conduit to protect the wiring into the hood. The grounding connection shall not be made to the terminal box cover. The fluorescent light has been mounted outside the top liner panel and is sealed from vapors inside the hood structure.
Chapter 3: Getting Started Connecting the Service Lines to the Protector XLE Fume Hood The hoods with service fixtures have been plumbed from the valve to the hose connector or gooseneck for your installation convenience. Supply tubing shall be provided by the qualified installer. Tubing can enter the hood from above, through the back, or through the work surface to make these connections to the service fixtures. ! NOTE: Inspect all fittings for leakage. Tighten the fittings slightly if needed.
Chapter 3: Getting Started Sealing the Protector XLE Fume 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.
