Chapter 3: Getting Started
Product Service 1-800-522-7658 13
Optional Exhaust System Connections
All Procedure Stations are shipped to recirculate their HEPA filtered exhaust
air back into the laboratory.
Certain applications such as working with odorous products or volatile toxic
materials will require the connection of the Procedure Stations to an exhaust
system.
Note: The canopy connection, also referred to as a thimble or air gap
connection, allows single or multiple biohazard cabinets to be connected to
an exhaust system. During operation, the exhaust system draws all of the
cabinet’s exhaust air, plus a volume of room air (through the slots in the
canopy) into the exhaust duct. Canopy connections function as a “shock
absorber” allowing the system to function properly during changes in room
air pressure.
For information on selecting a canopy connection, go to Chapter 7:
Accessorizing the Cabinet.
Warning: If the research involves the use of toxic compounds or volatile
materials, contact the facility’s safety officer or Labconco to ensure that the
Procedure Stations and its exhaust system are compatible with the materials
you will be working with.
Drain Valve Installation
In order to prevent damage during shipping, the drain valve assembly has not
been installed. If desired, the valve should be installed after the cabinet is in
its final location.
To install the valve assembly, follow these steps:
Note: The work surface is heavy. Use caution when handling it.
1. Lift the work surface out of the Procedure Station by lifting on the knobs
at the front of the work surface. Steady the work surface while pulling it
straight out the front of the cabinet.
2. Using a putty knife, remove and discard the stainless steel cover that is
sealed over the drain mounting holes. Scrape out remaining sealant that
is around the holes.
3. Apply a light coating of silicone sealant (user supplied) to the mounting
surface of the drain assembly. Attach the drain assembly under the
bottom of the cabinet as shown in Figure 3-4. Wipe off any excess sealant
from the cabinet bottom. Ensure that the center drain hole is
unobstructed.
4. Make sure the drain valve is in the closed position.
