READ THESE INSTRUCTIONS BEFORE
INSTALLATION and OPERATION.
SAVE FOR FUTURE REFERENCE.
Thank you for choosing a GSI Vision Series grain dryer. These units are among the finest grain dryers ever built; designed
to give you excellent operating performance and reliable service for many years.
This manual describes the installation and operation for all standard production model dryers. These dryers are available
with liquid propane or natural gas fuel supply, single phase 230 volt, three phase 230 or 460 volt (60Hz) electrical power.
USE CAUTION IN THE OPERATION OF THIS
EQUIPMENT
The design and manufacture of this dryer is directed toward operator safety. However, the very nature of a grain dryer
having a gas burner, high voltage electrical equipment and high speed rotating parts does present a hazard to personnel which
cannot be completely safeguarded against without interfering with efficient operation and reasonable access to components.
Use extreme caution in working around high speed fans, gas-fired heaters, augers and auxiliary conveyors which may start
without warning when the dryer is operating on automatic control.
Continued safe dependable operation of automatic equipment depends, to a great degree, upon the owner. For a safe and
dependable drying system, follow the recommendations within the manual and make it a practice to regularly inspect the operation
of the unit for any developing problems or unsafe conditions.
Take special note of the Operating Precautions listed below before attempting to operate the dryer.
Keep the dryer clean. Do not allow fine material to accumulate in the plenum chamber.
A CAREFUL OPERATOR IS THE BEST INSURANCE AGAINST AN ACCIDENT.
OPERATING PRECAUTIONS
1.
Read and understand the operation manual before attempting to operate the unit.
2.
Keep ALL guards, safety decals, and safety devices in place. Never operate dryer while guards are removed.
3.
Keep visitors, children and untrained personnel away from dryer at all times.
4.
Never attempt to operate the dryer by jumping or otherwise bypassing any safety devices on the unit.
5.
Always set the main power supply disconnect switch to OFF and lock it in the OFF position using a padlock before
performing any service or maintenance work on the dryer or the auxiliary conveyor equipment.
6.
Before attempting to remove and reinstall the fan blade, make certain to read recommended procedure listed within the
SERVICING section of the manual.
7.
Keep the dryer and wet holding equipment CLEAN. Do not allow fine material to accumulate.
8.
Set pressure regulator to avoid excessive gas pressure applied to a burner during ignition and when burner is in operation.
See page 19 for operating gas pressures. Do not exceed maximum recommended drying temperatures.
9.
Do not operate the dryer if any gas leak is detected. Shut down and repair before further operation.
10.
Clean grain is safer and easier to dry. Fine material can be highly combustible, and it also requires removal of extra moisture.
11.
Use CAUTION in working around high-speed fans, gas burners, augers, and auxiliary conveyors which can start
automatically.
12.
Be certain that capacities of auxiliary conveyors are matched to dryer auger capacities.
13.
Do not operate in an area where combustible material will be drawn into the fan.
14.
The operating and safety recommendations in this manual pertain to the common cereal grains as indicated. When drying
any other grain or products, consult the factory for additional recommendations.
15.
Routinely check for any developing gas plumbing leaks. Check LP vaporizer for contact with burner vanes.
