Sightglass:
The sightglass has the same dimensions as the stainless steel conveying piping, and is installed to
enable viewing the product as it is being conveyed, as well as permit inspection of the chain and
discs. The sightglass is made from durable polycarbonate, but can be scratched or dented if not
handled properly. When cleaning the sightglass, use a mild soap or detergent and wash with
lukewarm water and a clean sponge or soft cloth.
To avoid buildup of static electricity at the sightglass, it is important to ground the piping. Wrap
the supplied copper grounding wire around a sightglass to create a “bridge" reaching from the bolts
of the compression couplings at each end of the sightglass. Approximately 3ft [1m] of wire is
needed to accommodate a standard 20" [51cm] long sightglass. In some cases, the weight of the
surrounding conveying pipe may cause the sightglass to bend or bow. To avoid this, the supplied
structural support bar should also be installed as shown above.
Before installing any pipe section, elbow, sightglass, etc… first assure that all cuts are square, and
that both pipe ends are free of dents, sharp edges, or burrs.
Installation:
The tube ends are to be joined together with 4-bolt (8” [20.32cm] long) compression couplings.
The pipe connection point should be centered within the coupling, with equal lengths grasping each
pipe section. For best results, each pipe end should be marked at 4 inches (half of coupling length)
from its end. When tightening the coupling, assure that the pipe ends are held together squarely,
and that the ends do not separate when tightened.
Note: For better likelihood of keeping the pipe ends square and together, first partially tighten all
bolts and then go back and apply a final torque, always tightening the outer bolts first, then inner
bolts.
* Shorter 3-bolt (6” [15.24] long) compression couplings may be used if space is limited, but the 4-
bolt compression coupling is recommended for ideal support and straighter connections.
