INTRODUCTION
General Description
The Multi-Hazard Glove Box is equipped with a blower, air damper and filter system that
provide versatility for many particular applications. The variable speed blower provides air
volumes between 10 and 50 CFM and negative glove box pressure up to 1.5 inches H2O
gauge. The air damper provides a means for operating the glove box at a more negative
pressure when the blower is running at low speed (low air volume). The filtering system
consists of one inlet HEPA and one exhaust HEPA filter (both rated at 99.99% efficient on
0.3 micron particulates). A “roughing” prefilter is also provided to capture room air
particles and extend the life of the inlet HEPA filter.
Optional Filters: (for installation between exhaust HEPA and blower).
Charcoal Filter: (Cat. No. 5065300) contains 4 lbs. of Barnebey and Sutcliffe type 787
impregnated, activated carbon for removal of gaseous radioisotopes.
Additional Exhaust HEPA Filter Kit (Cat. No. 5065200) same as filter shipped with unit,
plus an extended length tube for connection to blower.

INSTALLATION
Location
Glove box should be placed on a stable, level base stand near an appropriate electrical
receptacle. The base stand must be capable of supporting 500 lbs minimum, and the height should
provide a comfortable working position through glove ports (normally 35" to 37" height for
standing position).
Connections, Exhaust
NOTE: It is the user’s responsibility to determine if the exhaust should be vented to
outside the building. If it is ducted to the outside, duct restrictions should not exceed 0.5 inches
water gauge static pressure at 50 CFM.
Glove Attachment
With glove thumbs up and right/left orientation, secure the gloves in place on the glove
ports by stretching the beaded glove cuff into the groove nearest the window. Install the 8"
diameter O-ring onto the outer groove over the glove surface.
Figure 4
Glove Replacement
If it becomes necessary to change gloves without disturbing the integrity of the glove box
environment, follow these steps:
1. Remove the O-ring from the old glove.
2. Roll the old glove cuff bead from the inner groove nearest the window to the outside
groove.
3. Insert the new glove through the old glove until the fingers of both are inside the glove box.
4. Stretch the new glove’s beaded cuff over the old glove cuff and into the groove nearest the
window.
5. To remove the old glove, grasp the new glove surface and manipulate the old glove bead
free from the outer groove.
6. With the other glove hand inside the box, pull the old glove into the glove box.
7. Install the O-ring over the new glove onto the outer groove.

SAFETY PRECAUTIONS
• This product is neither designed nor intended to be an explosion-proof enclosure. It
is the responsibility of the user to determine the lower explosive limits and
flammability of the enclosed gases and other matter. The user is also responsible
for using proper precautions to prevent equipment damage or injury due to
explosion or combustion.
• It is the responsibility of the user to determine the suitability of this product for the
intended applications.
12
NORMAL OPERATION
Start Up
NOTE: All internal wiring is protected by two manual reset circuit breakers located on the
rear panel.
• Confirm that the glove box electrical power cord is plugged into an appropriate
electrical power source.
• Switch on the fluorescent lamp and check to make sure bulb is working.
• Connect a test light to each interior receptacle and check for proper operation by
turning on the left and right outlet switches located on the control panel.
• Turn on the blower switch and check blower operation.
NOTE: This should be done with gloves installed so that glove box negative pressure will
be induced (observed by gauge on control panel). If the blower speed control is adjusted in
the low range, you will notice that the blower starts at a higher speed, then slows down.
• If unit is vented to the outside, confirm that ducting is sealed properly for positive
pressure operation.
Blower Operation
The blower is operated on and off by a switch located on the control panel. The speed of
the blower is regulated from 10% to 100% of maximum speed. Normal operation will be in the
30% to 50% area, depending on filter loading conditions and desired negative pressure within the
enclosure. It may be necessary, during continued operation to increase the blower speed to
compensate for possible restrictions to air flow caused by a dirty filter. The static pressure setting
should be within .25 to .5 H2O. Pressure settings higher than this may cause excessive air flow,
and are disruptive to operations within the enclosure.
13
ROUTINE MAINTENANCE
Estimation of Filter Condition
The negative pressure inside the box will give a good indication of filter and system
condition. Set blower speed dial to the speed that gives the proper negative pressure conditions
inside the box. Record both the blower speed dial setting and the pressure reading on the gauge.
If box pressure begins to drop due to filter loading, increase the blower speed. To check filters,
reduce the blower speed dial setting to the setting recorded when the filters were clean. Read the
differential pressure gauge. When the gauge reading is one-half of the initial reading, replace
filters.
Filter Replacement
When filters become contaminated or after a predetermined length of time in use, the filter
should be replaced. Only experienced personnel, competent in the procedure of filter replacement
should perform this procedure.
Suggested Plan for Decontamination
Activities such as filter changing, service work, moving the cabinet, or gross spillage
generally require a gas decontamination procedure.
ONLY EXPERIENCED PERSONNEL COMPETENT IN THIS
PROCEDURE SHOULD BE USED.
LABCONCO strongly recommends reference to the Laboratory Safety Monograph (a
supplement to the NIH Guidelines for Recombinant DNA Research), published by the U.S.
Department of Health, Education and Welfare, January 1979.
Reference may also be made to the Formaldehyde Decontamination booklet available from
the U.S. Department of Health, Education and Welfare, Public Health Service, National Institute of
Health, National Cancer Institute.
For decontamination procedures with formaldehyde, refer to the following information.
1. NCI Safety Standards for Research Involving Chemical Carcinogens. Publication No.
(NIH) 76-900, 1975.
2. Carcinogen Safety Monographs, NCI Office of Research Safety.

ROUTINE MAINTENANCE
Gloves
At least every three months (more often if subjected to heavy use), inspect the gloves for
signs of damage or wear. For replacement, refer to page 11.
Transfer Chamber Inner and Outer Door
Periodically check the closing tension of the door latches. Closing the latch handle should
require some firm force, indicating compression of the door seals. Seals, compression, and
latching force can be adjusted as follows:
1. Close and latch the door.
2. Using a 1/2" open-end wrench, turn the door adjustment screw (located between the door
and the latch bar) clockwise to increase seal compression and latching force. Turn screw
counterclockwise to decrease compression. Refer to figure 5.

ROUTINE MAINTENANCE
Fluorescent Lamp Replacement
1. Turn the light switch off and unplug the lamp power cord from the receptacle located on
the outside top of the cabinet.
2. From the top of the lamp housing, remove the two Phillips screws attaching the lamp
assembly to the top edge of the window frame.
3. Remove the lamp assembly from the unit.
4. The lamp tube can then be easily removed and replaced. Replacement lamp part #12779
(fluorescent lamp) #F30T12/CW/RS may be purchased from most local lighting supply
stores.
5. Re-install the lamp assembly and attach with the two Phillips screws. Plug in the power
cord and switch on the lamp. Refer to figure 6.
