INSTALL THROUGH TANK FITTING:
STEP 1: Locate the hatch where the GS-12-Air mixer will be installed through and mark a penetration
point on the roof for the penetration fitting. When selecting a penetration location be sure to confirm
the following:
A. The penetration is not going to hit an internal structure.
B. The penetration is centered within a clear footprint of approximately 8-inch X 8-inch (20cmX20cm)
C. The penetration is within arms reach of the hatch.
STEP 2: Use a cordless drill with the 1-5/16 inch (33mm) hole saw and begin drilling a hole through
the tank roof. A small amount of food grade vegetable oil or water works well for lubrication of the
hole saw. Prior to completing the penetration, position a catch bucket below the penetration point to
catch filings and the hole cut out. If a catch bucket is not readily available, use the cardboard box the
hole saw and fittings came in to catch the filings and disc cut out from falling into the tank.
STEP 3: Thoroughly clean all surfaces around the penetration of any filings before removing
the catch bucket. The penetration is now ready for a sealant application and installation of the
penetration fitting.
STEP 4: Apply a healthy amount of sealant on all the surrounding surfaces of the penetration (interior,
exterior, and inner wall). This will prevent future corrosion of the roof around the fixture.
STEP 5: Install the penetration fitting as shown below so that there is an interior and exterior nut and
gasket in place prior to tightening the fixture to the roof. Adjust the height of the fixture so the top is
approximately 3-1/2 inches (9cm) above tank roof. Tighten jam nut to firmly secure the fixture to the
roof using a large channel lock and pipe wrench.
