Page 4: 1-Principle Of Operation
PRINCIPLE OF OPERATION NOVATEC vacuum loaders utilize a powerful motor to create a vacuum, which draws material into a chamber. After the load time setting has expired, the vacuum motor is turned off and the negative pressure in the chamber is relieved. Material in the chamber then falls through the bottom, past the flapper while compressed air is pulsed through the filter to dislodge any contaminants or fines that may have accumulated. -
Page 5: 3-Vl Specifications
VL SPECIFICATIONS NOVATEC VL Series vacuum loaders are completely automatic self-cleaning vacuum loaders designed to convey virgin pellets and regrind materials from storage containers to drying hoppers or directly to process machines. Machine Mount Models with a sight glass are available as standards for all VL and VLP models. - Page 6 VL-VLP IM 19 JUNE 2017 © 2017 NOVATEC, Inc. All Rights Reserved Page 6...

Page 9: 5-Loader Installation
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. -
Page 10: 6-Operation Overview
OPERATION OVERVIEW Pressing the OFF/ON switch will start the vacuum motor, creating vacuum suction through the conveying line, to the pick-up wand and the loader will load material into the loader’s vacuum chamber for an adjustable length of time. When the load time is completed, the vacuum motor will stop, allowing material in the vacuum chamber to relax and flow through the dump valve to the hopper or machine below. -
Page 11: To Change Loading Parameters
8.1 TO CHANGE LOADING PARAMETERS 8.2 PARAMETERS EXPLANATION Motor-on Time (Pmp/LT), measured in seconds, is the amount of time the vacuum motor will run to load material into the loader’s vacuum chamber. Too little time will result in insufficient loading and will shorten motor life with too many start/stop cycles. Too much time will pack the loader full of material, prematurely blinding the filter and possibly clogging the conveying line. - Page 12 Prop Valve A Time (PValve/PVA) and Prop Valve B Time (PValve/PVB), each measured in seconds, is the amount of time dedicated to the loading of two materials with the use of an optional, external Proportioning Valve. The Proportioning Valve is installed on the material inlet of the VL or VLP loader (see separate instructions, accompanying the valve) and shuttles internal plungers between allowing A (typically virgin) and B (typically regrind) materials to be loaded during the course of the Motor-On time.
-
Page 13: 9-Use Of Proportioning Valves
USE OF PROPORTIONING VALVES Proportioning valves are a convenient method for introducing regrind into the process while vacuum loading of virgin material. The proportioning valve is typically installed onto the material inlet of the receiver and is connected to the central control system, or an accessory control specifically designed for proportioning valve operation. -
Page 14: Conveying Notes
10.1 CONVEYING NOTES Materials, which contain a large percentage of fines or powder, may require increased filter cleaning. This can be achieved by the following technique. A) Set the load time to minimum. B) Set the dump and pulse time to maximum. C) Increase the compressed air pressure. - Page 15 This ring provides the vacuum seal between the motor lid, the filter and the loader body. The ring must be smooth, clean and intact to provide a suitable seal for vacuum sealing. Replace the filter if the seal is not in perfect shape. Once cleaning/inspection is complete, the filter may be reinstalled by placing it on the flat rim of the loader body (cloth DOWN and coarse screen UP) and placing the motor lid down upon it and centering the filter...

Page 16: Vlp Series - Cartridge Filter Cleaning
11.2- VLP Series - CARTRIDGE FILTER CLEANING: VLP Series loaders are typically used for conveying free flowing powder materials. For this task, they are equipped with higher capacity cartridge filters. The amount of dust within the conveyed materials will determine the frequency of necessary manual filter cleaning. NOTE: Although the blowback system of the loader will extend the operational life of the filter media, it cannot be relied upon alone. -
Page 17: Vacuum Motor Brush Replacement
Once each cartridge is cleaned, completely dry and inspected, it may be re-installed onto the filter mounting plate in the same fashion it was removed. Examine the filter mounting plate to be sure it is intact and its perimeter seal is smooth and clean since it will form a vacuum tight seal between the motor lid, the filter mounting plate and the loader body. -

11.4- VL-12 through VL-38 and VLP-12 through VLP-38 MOTOR BRUSH REPLACEMENT Remove metal band from mid-section of motor by unscrewing the sheet metal screw in the side. Pull the cover back away from the motor, sliding it gently over the wires that pass through the grommet opposite the screw. -
Page 19: Motor Replacement
Reinstall new brush into motor housing and replace the retaining clip. Be sure to properly seat the nub on the bottom of the brush holder into the motor housing groove. Repeat steps 2 thru 5 for the adjacent brush. Replace the plastic shield on top of the motor by aligning it on top of the motor and pushing down until the spring clips on each brush snap into place. -
