while the sumps are heating up or cooling off.
SAVE THESE PIECES, DO NOT LOSE THEM!

INSTALLING AND SECURING YOUR B409
BEFORE INSTALLING PENETRATION FITTINGS
ENSURE THAT THE SUMP BODY IS HOLDING VACUUM.
If the gauge is Below 12 inches of mercury (Hg/Vacuum), then pressurize the
sump interstice to 4 PSI and submerge the gauge and tubing assemblies.
Soap test the test tubing fittings on the walls. If an air leak is found, contact
the factory. If no leak at the tubing
is found, soap test the rest of the sump
surface starting with the exterior. Visually inspect for damage. If the leak is found,
patch per repair directions in this manual.
If the gauge is
AT OR ABOVE 12 INCHES OF MERCURY
, proceed to
