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.
4. Lift the work surface out of the biosafety cabinet 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.
5. 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.
6. 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 3-3. Wipe off any excess sealant
from the cabinet bottom. Ensure that the center drain hole is unobstructed.
7. Make sure the drain valve is in the closed position.
8. Reinstall the work surface.
9. Allow the silicone sealant to cure for at least eight hours before exposing
it to liquid.
NOTE: The drain valve assembly
attaches to the underside of the cabinet
bottom.
Apply a light coat of silicone sealant to
this surface of the connector, aligning the
three holes in the connector with the three
holes in the biosafety cabinet liner.
