Installation
The cause of the tank gasket damage should be investigat-
ed and preventive measures taken. The tank should never be
overfilled: 25 inches of liquid is good, 27 inches too much.
1. The damaged gasket must
first be removed from the
edges of the tank frame
before the new one can be
installed. The gasket is
installed on both the upper
and lower sides of the
frame. See Figure 2.
2. Place the new gasket
out straight on a flat
surface, such as a table.
Run a line of silastic
on the inside groove of
the gasket, as shown in
Figure 3.

3. Install the gasket as
Figure 2
shown in Figure 2,
fitting it around the
edge of the tank
frame. The slight
curve goes toward
the tank (Figure 4).
4. When the end of the
gasket is reached, go
back over the gasket
one more time,
smoothing and fitting
it securely.
5. Trim the end of the
gasket so that the
ends of the gasket fit
closely together.
Check position peri-
odically during cure time.
