5- LOADER INSTALLATION
Mount the loader body to the hopper lid, positioning it so that the material inlet is directed towards
the material pick up point. Make sure the dump valve flapper plate has enough room to freely
operate. Secure the loader to the hopper lid with captive bolts or clamps to ensure a safe
installation with no chance of hardware vibrating loose.
On machine mounted units, the bottom flange is usually supplied undrilled to allow a range of
mounting patterns and hardware choices. A gasket is used to provide a tight seal between the
loader base and the machine throat.
Ensure a tight seal when securing the loader to the hopper or machine. This is particularly
important for VLP units that will be conveying powder. The conveying line should be horizontal
and/or vertical, using a 90 degree radius bend for directional changes, and it should be as direct
as possible with no slope. All line connections should be vacuum tight. Rigid conveying tubing
should be properly supported by the installer to provide a safe and secure installation. Use
flexible material handling hose to connect the material pick-up lance or vacuum take-off box to the
conveying line. The flexible hose should be only as long as needed, since excess hose will
reduce loader efficiency.
Connect a clean, dry compressed air supply line to the filter on the accumulator tank. The
minimum requirement for effective filter cleaning is 80 PSI.
CAUTION:
1. DO NOT EXCEED 125 PSI. COMPRESSED AIR.
2. PROPER SUPPORT OF ALL CONVEYING LINES AND A SECURE MOUNTING OF THE
HOPPER LOADER IS NECESSARY FOR A SAFE INSTALLATION.
5.1 CONTROL INSTALLATION
The VL/VLP control box may be
mounted in a location that is convenient
for the operator, making sure that the
control cable will extend to the junction
box on the lid of the hopper loader.
The power and connections cables
should be carefully routed away from
hot components or surfaces and away
from high voltage lines that may
produce undesirable electrical noise.
Connect the control to the power source
as required by the nameplate located
on the side of the loader control box.
CAUTION: FOLLOW ALL
NATIONAL and LOCAL
ELECTRICAL CODES.
