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, trac 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 ow 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 eective 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 sucient 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
tting on the sampler barrel. Use 36 inches of the length of 1/4-inch OD exible polyurethane tubing provided.
4. Press the tube end over the barb tting 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 rmly, 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.
