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 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.
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.
5. Reinstall the work surface.
6. 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.
