6" Hard Duct Exhaust Connector No. 5230400
Operation
The 6" Hard Duct Exhaust Connector attaches to the top of the glove box blower for exhausting
air to the outside. The glove box blower harness must be disconnected when using the hard duct
connection as the exhaust blower provides the only means of moving air through the glove box.
Consult Labconco for separate purchase of a roof-mounted blower (P/N 4863500), damper (P/N
3924000 or P/N 4724200), and 6" diameter x 8' long hose (P/N 3927600) to exhaust the glove
box to the outside. Follow the installation procedure below to properly connect the 6" Hard Duct
Exhaust Connector.
Installation Procedure
1. Disconnect all power to the glove box and glove box blower. The power to the glove box
blower from the harness will be permanently disabled.
2. Remove the perforated plate on top of the blower as identified in the attached pictorial and
replace it with the 6" Hard Duct Exhaust Connector.
3. Secure the 6" Hard Duct Exhaust Connector with silicone sealant and reattach the 8
screws.
4. Attach an accessory 6" diameter hose or duct to the connection in the ceiling and to the 6"
Hard Duct Exhaust Connector. If needed, a Labconco 6" diameter x 8' long hose (P/N
3927600) may be ordered. Additionally, Labconco roof-mounted blower (P/N 4863500)
and damper (P/N 3924000 or P/N 4724200) may be ordered if exhausting to the outside
with a dedicated blower system. The damper is required to properly adjust the airflow.
5. The 6" Hard Duct Exhaust Connector must be tested and confirmed to draw room air
through the inlet HEPA filter and out through the HEPA filter. A visual smoke test is a
good method for confirmation. The exhaust system blower and damper must be set at an
airflow volume approved by your Safety Officer. CAUTION: With sensitive weighing
operations, it may be necessary to lower the exhaust system airflow below 50 CFM.
6. Reconnect all external power to the glove box, but do not reconnect the power to the glove
box internal blower.
7. Installation is now complete.
