NOTE:
IF THE SURFACE AREA TO WHICH THE MOUNTING PLATE IS TO BE ATTACHED IS WARPED
OR BENT, STRAIGHTEN AND SMOOTH THE METAL SO THE SAMPLER WILL BE PROPERLY ALIGNED
WHEN THE INSTALLATION IS COMPLETE. THE SURFACE TO WHICH THE SAMPLER IS MOUNTED MUST
NOT FLEX.
NOTE:
OVER TIGHTENING THE MOUNTING FASTENERS WILL WARP OR CRACK THE SEAL HOUSING
FLANGE. IMPROPER SAMPLING WILL RESULT.
3.4.1 Factory Pre-Mounted Sampler
As furnished, the premounted sampler is already firmly attached to a length of tube, pipe, etc.
A. Remove a section of pipe or chute work where the sampler is to be installed.
B. Remove the sampler from the sampler premount by removing the hinge pins and remove the auger &
auger tube.
C. Locate the sampler premount in the desired position.
D. Attach the sampler premount using one of the following methods.
1-Weld the sampler premount ends directly to the existing pipe or chute work.
2-Clamp the sampler premount ends to the existing pipe utilizing compression couplings.
3-Weld matching flanges to the existing pipe or chute work and sampler premount.
E. Re-install the auger & auger tube. Verify that the auger tube rotates without interference.
F. Install the sampler drive assembly by re-installing the hinge pins.
3.4.3 Field-Mounted Sampler Using Weld-On Plates
Weld-on plates are typically used when mounting the sampler to a large existing surface, such as on a storage
hopper or a long section of chutework.
A. Locate and mark the desired mounting location on the conveying line.
B. Cut and de-burr two 4" diameter holes (opposite each other) in the product line through which the
sample tube will pass to collect material samples.
C. Position the sampler drive mounting plate by centering the auger hole over the 4" diameter clearance
holes.
D. Tack weld the sides of the mounting plate to the product line surface and double check alignment.
E. Weld a continuous bead around all sides of the mounting plate. Also from the inside of the chute weld
a continuous bead around the 4" diameter clearance hole.
NOTE:
WHEN WELDING THE MOUNTING PLATE TO THIN GAUGE SHEET OR THIN PLATE, SKIP WELD
ALTERNATING SIDES OF THE MOUNTING PLATE TO LIMIT HEAT INPUT TO MINIMIZE WARPING.
F. Insert the auger tube through the drive mount plate and verify that the auger tube rotates without
interference.
G. Locate the discharge mounting plate assembly by slipping it over the end of the auger tube.
