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
located on the back of the unit.
CAUTION: Each operator must determine if the glove box exhaust should be ventilated
and/or filtered for protection of health and environment.
4. Glove Box Gas Fill. 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. Connect to your glove box inert gas
supply. Excessive gas supply pressure will cause difficulties in throttling the manual
valves on Models 506000000 and 506010000 to maintain desired glove box pressure.
5. Electrical Receptacle for Vacuum Pump. Connect the pump electrical supply cord to the
receptacle located on back of the glove box. This receptacle is controlled by the “exterior
outlet” switch on the front control panel and is protected by a manual reset circuit breaker
located on the rear panel.
NOTE: On Models 507000000, 507010000, 508000000 and 508010000, this receptacle is
automatically controlled when the front control panel switch is in the “Auto” position.
CAUTION: Each operator must determine if pump exhaust should be ventilated and/or
filtered for protection of health and environment.
