DUSTLESS LOADING/SELF-CONTAINED DUSTLESS LOADING SPOUTS
GENERAL INSTALLATION
10
2. Check the alignment of the bolt holes on both the mating flange and the support steel
to determine if the bolt holes will match correctly with the unit. Do not attempt to
correct alignment by drilling through the flange, as this will possibly weaken the
flange and result in a poor seal. Check the mating flange for level.
3. Install the appropriate gasket material or sealant on the top flange surface of the
housing.
4. Using a fork truck or other appropriate equipment, lift the spout to the mating flange.
5. Install nuts and washers. Use only a high grade hex head bolt with an equal grade of
nut, flat and lock washer. Lock washers and/or a thread locking material should be
used. Angle supports on top of the housing assembly must be utilized for additional
support to the hopper or other rigid steel structure to ensure that the housing assembly
is installed securely; the unit CANNOT be supported solely by the flange.
6. The skid and packing can now be removed.
7. Install the dust collection hose/pipe to the side outlet of the housing using an appropriate
gasket material. (Not necessary for SCDLS units)
8. Electrical connections to the drive motor, rotary limit switch, and optional equipment can
now be made. Refer to the provided wiring diagrams for more information.
!!! WARNING !!!
Until the Rotary Limit Switch has been checked to ensure proper adjustment, DO NOT
FULLY RETRACT THE SPOUT, as over retracting may cause damage to the unit.
PEBCO®
DLS systems are shipped extended approximately 4 inches from the fully
retracted position to protect against over retracting during installation.
9. Check the motor for correct rotation.
10. Continue to
Section 6.7
for rotary limit switch adjustment.
11. If the DLS contains automatic-raise or level switches, they should be tested by manually
tilting the sensing probe. Make sure that this activates the spout motor or relays a signal
to the operator.
12. For SCDLS units, continue to
Section 4.3.3
NOTE:
After one week of service, it is recommended that a complete check of all
fasteners be made to ensure tightness.
4.3.2 Installation of Unassembled Units
Large DLS units are generally shipped with subassemblies on separate skids as follows:
•
Housing assembly, including drive assembly and lift cables wound on single-groove lift
pulleys
•
Outlet assembly
