Disassembly and

Reassembly of the

Protector XL Floor-Mounted

Hood

There may be some disassembly and reassembly work, due to the large physical size of your laboratory hood and the ability to maneuver it into your laboratory.

This is specific to each customer.

Lower Base Installation of the Protector XL Floor-

Mounted Hood

The lower base features a panelized liner surrounded by an epoxy-coated steel and galvanized steel framework.

Both the left and right side panels should be removed to allow for the correct placement of the lower cabinet assembly. Temporarily remove both vertical-rising sashes shipped with the lower base (on vertical-rising sash models only). Position the lower base on a level floor surface. Place the vertical-rising sashes back in place (on vertical-rising sash models only).

NOTE: If an optional floor surface is purchased, it should be positioned on the existing floor prior to placement of the lower cabinet installation. See Figure

3-1.

14

Upper Cabinet Installation of the Protector XL Floor-

Mounted Hood

Remove the upper cabinet assembly side panels and front panels prior to cabinet placement. Then place the upper cabinet assembly on top of the lower base assembly, being careful to clear the lower base assembly during placement. To prevent spillage from seeping between the two liner assemblies, run a bead of white RTV sealant between the sections once they have been properly aligned. Mount the lower base to the upper cabinet using the ¼-20 hex head screws, lockwashers, and nuts included in your hood package.

See Figure 3-2.

Vertical-Rising Sash

Installation for the 4', 5', 6',

& 8' Floor-Mounted Hoods

The Vertical-Rising Sash Floor-Mounted Hood has two vertical-rising sashes. The rear vertical-rising sash moves from the floor to full open and picks up the front vertical-rising sash, which travels from the midpoint to full open. The sash tracks should be adjusted left to right to assure the sash will work properly. The vertical-rising sashes are shipped installed in the tracks; however, the counterbalance weights must be installed.

The large single sheet metal sash weight is installed in the middle and attached to the upper front sash. The two individual sash weights counterbalance the rear vertical-rising sash; these weights have rollers and ride in the rear sash tracks that straddle the middle sheet metal sash weight. Install the rear weight tracks for the individual sash weights with the #10-24 flathead screws and #10-24 KEPS nuts supplied. See Figure 3-2 and

Figure 3-4. It is vitally important that the front upper and lower sash tracks are fully aligned and the strap plates are used to secure this alignment. See Figure 3-3 and Figure 3-4. Once the sashes are aligned and operating freely, secure the lower base to the floor with sealant or fasteners. (Hardware not supplied due to installation variables.) Securing the lower base will ensure the sashes will work freely.

As a last step, install the four rubber bumpers with #6 screws supplied. One set of rubber bumpers prevents the front upper sash from traveling too low. The second set of rubber bumpers prevent the rear lower sash from touching the floor and provides a good sweep of clean air across the floor. See Figure 3-3.

Lower Sash Track &

Threshold Installation for

Horizontal-Sliding Sashes on 8', 10', 12', & 16' Floor-

Mounted Hoods

The lower sash track assembly is comprised of a sash track threshold, front and rear ramps, and threshold support brackets. With the corner posts removed the sash track threshold should be placed on the floor between the left and right corner posts, with their corner posts removed at this time. Lay the threshold flat, perpendicular to the hood liner walls. The sash track threshold will extend to the hood sidetracks. Once the sash track threshold has been placed in its final position, check to be sure it is level. It must be level to ensure proper movement of each of the door assemblies. If the threshold is not level, place shim material under it until it becomes level. Attach the sash track threshold to the hood sidetracks with the threshold support brackets and #10-24 hardware. Both front and rear ramps are held in position without mechanical fasteners and can be removed for easy cleaning, should it be required. Simply place the flange of each ramp assembly in the position as shown in the diagram below for proper fit. The ramps are self-leveling to match your existing floor conditions. The hood corner posts should be installed prior to the placement of the front sash ramp. See Figure 3-5.

The Floor-Mounted Hood with horizontal-sliding sashes is supplied with four individual sash doors.

These doors have been packaged separately during shipment and require installation in the field. The doors should not be installed until the lower sash track threshold has been properly installed. Each door assembly is provided with two mounting brackets with nylon roller bearings. The roller bearings have been positioned in the center location of each mounting bracket to provide for maximum door adjustment. The upper header sash track features two tracks that will support two of the door assemblies. Raise the door panel up and into the upper track section on your hood and place the nylon roller bearings directly in the track section. At the same time, position the bottom edge of

End Support for

Header Sash Track the door assembly into the corresponding lower track slot. As each door is placed into position, slide the door the full length of the track assembly to assure proper height adjustment. If the door drags in the lower track, adjust the nylon roller bearing on the mounting bracket to raise the height of the door. Reverse the movement of the bearing should the door assembly be too short and not fit in the lower track properly. An average space of 1/4" to 5/16" should be left between the bottom of each door and the bottom of the lower sash track for proper door travel. Repeat this procedure for the four door assemblies and place two of the doors on each of the front and rear track runners. Once proper door operation has been achieved, the sash track threshold should be permanently attached to the floor.

Anchor bolts should be used in the holes provided in the lower sash track threshold mounting. The anchor bolts are not supplied. RTV sealant can also be used to hold the lower sash track threshold in position during normal operation. See Figure 3-6.

Corner Post Installation for the Floor-Mounted Hoods

Both left and right corner posts have been shipped uninstalled. The one-piece corner posts are to be installed once the upper and lower cabinet assemblies have been properly positioned.

The edges on the corner posts fit directly onto the side frames. The front inner edge of both corner posts are held in place by stainless steel machine screws. The outer back edge of both corner posts are held in place with steel self-drilling screws. The screws are included in the hood manual packet. See Figure 3-2 and 3-3.

Baffle Installation for the

Floor-Mounted Hoods

The baffles are critical to the proper airflow for the hood. The Floor-Mounted Hood includes adjustable baffles at three of the four slot locations. These are the bottom slot, second from the bottom slot, and the upper slot. Be sure the baffles are resting in the proper baffle mount supports. See Figure 3-7 for various sizes of baffles and their orientation.

Should you require more airflow at the bottom for heavier than air gases then you can open up the two lower adjustable baffles. Should you require more airflow at the top you can open up the upper adjustable baffle for lighter than air gases.

The fluorescent light has been mounted outside the top liner panel and is sealed from vapors 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 reflector(s). Remove the light reflector(s) and slide out of the way temporarily. The fluorescent lights are now fully exposed and ready for service. While the fixture is in this position, replace the defective bulbs, and reassemble.

Connecting the Service

Lines to the Protector XL

Floor-Mounted Fume Hood

The hoods with service fixtures have been plumbed and factory checked from the valve to the hose connector or gooseneck. For shipping purposes, the plumbing is then disconnected and can be re-installed by the installer. The qualified installer shall then supply the inlet tubing. To make these inlet connections, tubing can enter the hood from above or through the back as long as it misses the vertical-rising sash weights.

!

NOTE: Inspect all fittings for leakage. Tighten the fittings slightly if needed.

!

CAUTION: Do not use oxygen with any standard

service fixture. Contact Labconco Customer

Service for oxygen fixture information.

Should access to the hood plumbing fixture bodies be required, remove the service access plate on the hood front corner posts by loosening their individual screws.

(See item 11 Figure A-1, page 48 and 49) The valve body will now be fully exposed for any service work that may be necessary. The service fixtures supplied on your laboratory hood are designed for use with the following services:

•

Cold Water

•

Natural Gas – See caution below

28

Chapter 3: Getting Started

! WARNING: Contact Labconco Customer

Service before using any service other than those listed above in these valves to assure full compatibility.

!

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.

Sealing the Protector XL

Floor-Mounted Hood to the

Floor

When the hood has been set in place, ducted, wired, and plumbed, it should be sealed to the floor 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 XL

Floor-Mounted 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 D

– Reference) Labconco recommends an average face velocity at the sash opening of 80 to 100 feet per minute. Consult Labconco Customer Service for proper airflows 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 0.10 part per million (ppm) at 4 liters per minute (lpm); AM<0.10

(consult Labconco for individual fume hood ratings).

For “field use” ASHRAE testing contact Labconco

The Protector XL Floor-Mounted Laboratory Hood is designed to meet the needs of the laboratory scientist who must transport equipment and products for experimentation, and testing under a laboratory fume hood. The Floor-Mounted Fume

Hood has been designed to effectively contain toxic, noxious, or other harmful materials when properly installed. The hood features by-pass airflow design that allows the hood face velocity to remain relatively stable as the sash is closed. Airflow is diverted behind the front panel to help control fluctuations in face velocity, which occur as the sash is closed.

31

Chapter 4: Performance Features and Safety Precautions

1. Unique sash provides maximum visibility.

Vertical-rising sashes may be raised from a closed to 58.81" operating height; this feature is available on 4', 5', 6', and 8' floor mount models.

Exhaust volume, and blower sizing is based on the rear sash being closed and the front sash opened. For horizontal sashes on 8', 10', 12', and 16' models, the opening is half the total opening and exhaust volume is based on half the total visible opening for the 8' model and exhaust volume is one quarter the total visible opening for 10', 12', and 16' models. The actual vertical opening is 68.15".

2. By-pass airflow design ensures relatively stable face velocities.

3. Large usable interior work depth and

interior height of 48" at the front of the liner provides ample working space.(Not shown)

4. Baffles (not shown) direct airflow to the rear of the interior to provide efficient airflow. The baffles may be removed for cleaning purposes only. Three of the four baffles are adjustable.

Should you require more airflow at the bottom for heavier than air gases, then open up the lower baffle. Should you require more airflow at the top, then open up the upper baffle for lighter than air gases.

5. Exterior access cover plates are removable for easy access to plumbing valves when access through the sides is not available.

6. Lift-Away™ front panel provides easy access to electrical wiring, sash weights, and lighting fixtures.

7. Energy efficient fluorescent lighting is located behind a laminated safety glass shield mounted to the top of the hood. The factory-wired instant start T8 lighting is serviceable from outside the hood cavity.

8. Low mounted, factory-wired light and blower

switches are ADA compliant.

32

Chapter 4: Performance Features and Safety Precautions

9. Streamlined corner posts provide maximum visibility and the flexibility to add services after installation.

10. All hoods are factory-prepared for up to 8

service fixtures.

11. Duplex electrical receptacles are mounted on the right and left corner posts as requested.

Receptacles are factory-wired to hood single point junction box.

12. Accessory Guardian™ Digital Airflow

Monitor or Guardian Jr. Monitor continuously monitors face velocity. An audio/visual alarm alerts the user to low airflow conditions. The right corner post is factoryprepared to accommodate the Guardian Monitor

(sold separately).

13. Frame of epoxy-coated steel and aluminum is durable and corrosion-resistant.

14. Exhaust connection. The hood features 12"

(12.75" OD pipe) exhaust connections sized to allow for a minimum static pressure loss through the hood structure while providing a good transport velocity through the exhaust system.

15. Optional Ceiling Enclosure Kits (not shown) are available for a decorative facade between the hood and the ceiling.

Chapter 4: Performance Features and Safety Precautions

!

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 your head inside hood. Keep hands out of hood as much as possible.

Always work as far back in hood as possible. It is best to keep all chemicals and apparatus 6" inside the front of the hood.

On vertical-rising sash models, always close the rear sash for proper airflow; on horizontalsliding sash models work in the minimum required opening for maximum safety.

This hood does not feature explosion-proof electrical components, unless ordered separately. Therefore, use of flammable or explosive materials in quantities above the explosive limit are not recommended.

Do not work with chemicals in this hood without the exhaust system running. Do not store chemicals in a fume hood.

Perchloric acid use in this hood is prohibited.

High-level radioisotope materials are prohibited for usage in this hood.

THE HOOD. AIR

DISTURBANCES 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 XL Floor-Mounted

Hood should be certified by a qualified certification technician before it is initially used. The hood should be re-certified whenever it is relocated, serviced or at least annually thereafter.

Ensure that the unit is connected to electrical service in accordance with local and national electrical codes. Failure to do so may create a fire or electrical hazard. Do not remove or service any electrical components without first disconnecting the hood from electrical service.

Proper operation of the fume hood depends largely upon the hood’s location and the operator’s work habits. Consult the Reference

Manual in Appendix D.

•

Ambient temperature range: 41° to 104°F (5° to

40°C).

•

Maximum relative humidity: 80% for temperatures up to 88°F (31°C), decreasing linearly to 50% relative humidity at 104°F

(40°C).

•

Main supply voltage fluctuations not to exceed

±10% of the nominal voltage.

•

Transient over-voltages according to Installation

Categories II (Over-voltage Categories per IEC

1010). Temporary voltage spikes on the AC input line that may be as high as 1500V for

115V models and 2500V for 230V models are allowed.

•

Used in an environment of Pollution degrees 2

(i.e., where normally only non-conductive atmospheres are present). Occasionally, however, a temporary conductivity caused by condensation must be expected, in accordance with IEC 664.
