1.0 PRINCIPLE OF OPERATION
A Load Cycle begins with a compressed air blowback
pulse to clear any isolated material particles or dust
buildup that may remain on the flapper discharge valve.
This action ensures a tight vacuum seal for each Load
Cycle.
The loader then activates our powerful, maintenance
free, brushless 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 nega-
tive 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 dis-
lodge any contaminants or fines that may have accumu-
lated. This cycle is repeated as many times as necessary,
until the unit is shut off by the rise of the conveyed ma-
terial in the area below the loader which trips the level
switch, removing the 'demand' signal.
Machine mounted units do not have a flapper valve or
demand switch, but instead utilize a clear sight tube,
which mounts directly to the machine throat, with a sen-
sor to control loader operation based upon the level of
material within the sight tube. The sensor may be either
a capacitance style, with sensitivity adjustment, or a pair
of photoelectric sensors, an emitter and a receiver.
The bottom flange of a Machine Mount unit is normally
supplied undrilled to allow the customer to drill the ap-
propriate mounting pattern for a particular process ma-
chine.

2.0 UNPACKING AND INSPECTION

NOVATEC Vacuum loaders are shipped complete, with
all controls for automatic operation. The only utilities
required are a 115 volt power supply and clean, dry com-
pressed air at approximately 80 PSI.
After receipt of the unit, completely inspect it for dam-
age. All units are packaged securely at the factory. Please
report any damage to your carrier promptly.

3.0 SPECIFICATIONS

NOVATEC GSL Series vacuum loaders are completely
automatic self-cleaning vacuum loaders designed to con-
vey virgin pellets and regrind materials from storage con-
tainers to drying hoppers or directly to process machines.
Each unit is shipped complete with all controls for imme-
diate operation, and include a hardware package. The
hardware package includes 15 feet of flexible vacuum
hose, hose clamps and a material pick up lance, plus a 12'
extension cable for remote mounting the standard Con-
trol Pendant.
The GSL is designed for mounting on drying hoppers.
The GSL can be modified for use as a machine mount
unit on processing machines by adding a machine mount
assembly with an 8, 12, or 16 lb. capacity site glass with a
height adjustable photo-eye demand switch.
