equipment from road dirt and damage, or in case of electric drive motors for pumps, from excessive exposure to
cleaning sprays .
Select a location to install the sampler where the material in the process stream is well mixed . Location of the sampler
and controller is very important for accurate sampling results . They should be as close together as practical, within
sight of each other, and protected from weather, traffic damage and normal work activities in the area .
When selecting a sampler location, ensure the sample collection container will clear vertical lines (or other
obstructions) when mounted onto the sampler . The sampler can be used on a pipe or tank running horizontally,
vertically or at an angle, but the axis of the sampler body must be horizontal .
Sampler Installation
Install the sampler by using a line mounting tee that positions the sampler nose (front of body) close to the main
sample flow stream . In this position, samples are taken directly from moving product . A short 1-1/2-inch ferrule clamp
port on the side of the adapter tee (as recommended and/or furnished by Sentry Equipment Corp) provides the
proper line mounting location for the sampler .
If a standard Sentry adapter tee cannot be used, a 1-1/2-inch tri-clamp style ferrule clamp port must be devised . The
ferrule branch should be just long enough to accept the sampler mounting clamp without interference . The factory
standard is 5/8-inch from the ferrule face to the outside of the line .
Refer to your system application drawing included with this manual and the following section in this manual to install
the sampler controller in its most effective location .
1. The line where the sampler is to be located can be horizontal, vertical or at any angle . The location selected must
mount the sampler body with its long axis horizontal and with sufficient clearance beneath the unit for ease of
sample container mounting and exchange .
2. Disconnect the piping, insert the sampler mounting tee, and reconnect the piping to the tee . Attach the sampler
to the short 1-1/2-inch tri-clamp ferrule port on the tee with the clamp and gasket .
3. Check to ensure the sampler body is horizontal . Loosen the tee and rotate it if required . Install the air line to the
fitting on the sampler barrel . Use 36 inches of the length of 1/4-inch OD flexible polyurethane tubing provided .
4. Press the tube end over the barb fitting by hand . No external clamps are needed . Use no more than 36 inches
of connecting airline; shorter if practical . Remember, the sampler must be removed from the piping for daily
cleaning . Air lines longer than 36 inches may restrict the sampler's maximum cycle rate .
5. If a bag or vial adapter will be used, insert the o-ring seal into the sampler body port . It seats into a groove above
the threads . Screw the adapter into the 24 mm threaded discharge port of the sampler . Turn in firmly, by hand . DO
NOT USE TOOLS . Excess force could bind or gall stainless threads .
Controller Installation
Refer to your system application plus the controller group drawings included with this manual .
Select a location in an equipment cabinet, preferably a "dry" compartment area where using the sampler controller will
be convenient for the operator, yet protected from direct exposure to cleaning solutions or wash water sprays .
Avoid positioning the sampler controller in any location where milk, water, cleaning solutions,
tools, etc . could cause damage .
