INTRODUCTION
Performance
The Labconco Protector Controlled Atmosphere Glove Box provides an effective physical
barrier between the laboratory and the glove box interior. This barrier system results in three
distinct advantages. First, it helps protect the technician from hazardous materials. Secondly, it
protects valuable laboratory materials against the effects of ambient air and moisture. Finally, it
provides a protective, leak-tight environment as required for your research testing or production
procedures.
A transfer chamber enables samples, materials or equipment to be passed between the
laboratory and the glove box while maintaining an established glove box gas environment.
Environment Conditions
This equipment is designed to be safe under the following conditions:
• Indoor use
• Altitude up to 6562 Ft. (2000m)
• Temperature 41° to 104° (5° to 40°)
• Maximum relative humidity 80% for temperatures up to 88°F (31°C) decreasing
linearly to 50% relative humidity at 104° (40°C)
• Mains 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)
• Pollution degrees 2 (Normally only non-conductive foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric strength or
surface resistively occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected), in accordance with IEC 664

INSTALLATION
Location
The glove box should be placed on a stable, level base stand equipped with a lower shelf to
accommodate a vacuum pump near an electrical receptacle rated at 115V, 60 Hz, 20 amp for 115
volt models, or 230V, 50 Hz, 10 amp for 230 volt models. The base stand must be capable of
supporting 500 pounds minimum, and the height should provide a comfortable working position
through the glove ports. Recommended clearance between the back of the glove box and the wall
is 18 inches minimum to provide convenient access to connections on the rear of the unit. Frontal
clearance of approximately five feet should be ample to allow passage of personnel while a
technician is working at the front of the unit.

INSTALLATION
Pressure Relief Bubbler
The Pressure Relief Bubbler operates with vacuum pump oil having a specific gravity of
0.87. The user must determine the compatibility of substances used in the glove box with vacuum
pump oil.
The Pressure Relief Bubbler is designed to relieve positive and negative pressure in the
glove box. The relief pressure point is established by the amount of oil that is poured into the
bubbler at time of installation. The oil level may be varied to relieve pressure at any point between
± 10" H2O. Recommended relief pressure is 7" H2O.
The bubbler operates on the same principle as a U-tube manometer. When pressure or
vacuum is applied to the bubbler, the oil level in one column will decrease as it increases in the
other column. The vertical difference between the two oil column levels indicates the pressure or
vacuum applied to the bubbler. When this pressure becomes sufficient to lower the oil level in one
of the columns to the level of the return bend, any additional pressure or vacuum is vented through
the full column by oil bubbling. The accumulator at the top of each column traps oil droplets in
the relief pressure air stream and prevents them from escaping the bubbler. The user must
determine whether the exhaust port of the bubbler should be filtered or vented outside the
laboratory.
CAUTION NOTES:
A. Failure to install the pressure relief bubbler may result in equipment damage or personal
injury due to inadvertent over pressurization or excessive decompression of the glove box.
B. If the bubbler exhaust is to be filtered or vented outside the laboratory, it is the user’s
responsibility to ensure that any additional airflow restriction is less than 0.5" H
O static
2
pressure.
C. In case of excessive decompression, the user must determine whether laboratory
atmosphere entering the glove box could result in fire or explosion hazards.
The Pressure Relief Bubbler with mounting hardware and a 1-liter bottle of vacuum pump
oil is packaged in a separate carton located above the transfer chamber. The bubbler must be
installed to avoid equipment damage or personal injury. Install according to the following steps
and refer to Figure 5.
1. Attach hanger bracket to top back edge of cabinet with #8 x 1/2" screw. Leave screw loose
to allow adjustment later.
2. Attach bubbler to hanger bracket with the nut, washer and _-20 screw (installed on the
upper cross member of the bubbler). Leave the nut untightened for later adjustment.
3. Insert lower end of bubbler into the Swagelok fitting. Make sure the bubbler tube end and
brass conical shaped ferrule enters the fitting freely with no binding. Thread the Swagelok
nut onto the fitting by hand until hand-tight. Hold the fitting with a wrench and tighten the
nut an additional _ turn.

INSTALLATION
4. Hold the bubbler straight (with the vertical tubes perpendicular to the glove box base) and
tighten the top hanger bracket #8 x 1/2" screw. Secure the bubbler to the hanger bracket by
tightening the _-20 nut.
5. Remove the pipe plug from the fill spout and fill the bubbler with vacuum pump oil (.87
specific gravity) to the desired pressure relief level (must be less than 10) as indicated on
the graduated sight glass (inches H
applications. When nearing the desired fill level, add a small amount of oil at a time and
wait for it to drain into the bubbler and sight glass. When the desired level is reached,
install and tighten the fill spout plug.
NOTE: When loosening or tightening the fill plug or drain cock, be sure to hold the
bubbler’s stationary fitting with a wrench to avoid damage to the bubbler’s soldered joints.
O). The recommended level is 7 inches for most

Gas and Vacuum Internal Connections (Models 506000000, 506010000, 507000000 and
507010000)
Before making gas and vacuum connections on all models except 508000000 or
508010000, determine if the transfer chamber should be backfilled with gas directly from your
inert gas supply tank or from the glove box. If the transfer chamber is to be backfilled from the
glove box on Models 506000000 and 506010000 (without automatic pressure control), it will be
necessary to throttle the glove box “gas in” manual valve and the transfer chamber “gas fill”
manual valve while the transfer chamber is filling in order to prevent excessive glove box
decompression.
The glove box has been shipped with internal connections made for backfilling the transfer
chamber from the gas supply tank. If this is the method desired for backfilling, no other internal
connections are required. However, if you desire to backfill the transfer chamber from the glove
box, it will be necessary to make internal reconnection as follows: See Figure 6.
1. Remove rear access panels with Phillips type screwdriver.
2. Disconnect the transfer chamber “gas fill” tube from the Swagelok union located above the
transfer chamber.
3. Remove the Swagelok plug from this tee.
4. Install the tube assembly (Catalog No. 5079500) supplied with your unit.
5. Reinstall rear access panel.
Models 508000000 and 508010000 are supplied with internal connections and solenoid
valves to allow the user to select the gas source for transfer chamber backfilling by actuating “gas
source” switch on the front control panel. No internal reconnection is required.

Gas and Vacuum External Connections
All gas and vacuum connections are located on the back of the transfer chamber housing
and are clearly labeled as shown in Figure 7.
1. Vacuum Pump Connection. This is a copper tube of 7/8" O.D. on Models 506000000,
506010000, 507000000, and 507010000. On Models 508000000 and 508010000, this is a
solenoid valve with 3/4" female pipe connection. Connect to your vacuum pump intake. A
vacuum pump with capacity ranging from 110-190 liters per minute is recommended. On
Models 508000000 and 508010000, this connection must be made to the vacuum pump
controlled automatically by the electrical receptacle mounted on the back of the unit.
2. Transfer Chamber Gas Fill. This is a 3/8" Swagelok connection on Models 506000000,
506010000, 507000000, and 507010000. On Models 508000000 and 508010000, this is a
solenoid valve with 3/8" female pipe connection. Connect to your inert gas supply.
NOTE: On Models 506000000, 506010000, 507000000, and 507010000, disregard this
fitting if you wish to backfill the transfer chamber from the glove box, and have made
internal reconnection as shown on Page 14.
3. Glove Box Exhaust. This is a 3/8" Swagelok connection on Models 506000000 and
506010000. On Models 507000000, 507010000, 508000000 and 508010000, this is a
solenoid valve with 3/8" female pipe connection. This allows connection to a vacuum
pump for purging the glove box or to enable the glove box to be operated under negative
pressure. On Models 507000000, 507010000, 508000000, and 508010000, this connection
must be made to the vacuum pump controlled automatically by the electrical receptacle
