Thank you for choosing a Top Dry Series Autoflow.
It is designed to give excellent performance and ser-
vice for many years.
This manual describes the installation for all
standard production Top Dry single fan, multi-fan
and Heater Control units. Different models are avail-
able for liquid propane or natural gas fuel supply,
with either single-phase 230 volt, or three-phase 208,
220, 380, 460 or 575 volt electrical power.

("GSI") is your safety and the safety of others asso-
Fan/Heater Installation & Operating Instructions
SAFETY
As owner and/or operator, it is your responsi-
bility to know what requirements, hazards and pre-
cautions exist, and to inform all personnel associ-
ated with the equipment or who are in the fan area.
Avoid any alterations to the equipment. Such al-
terations may produce a very dangerous situation,
where serious injury or death may occur.
ciated with grain handling equipment. This manual
is written to help you understand safe operating pro-
cedures and some of the problems that may be en-
countered by the operator or other personnel.

Autoflow Operation
The GSI Group Inc. recom-
mends contacting your local
power company, and having a
representative survey your instal-
lation so the wiring is compatible
with their system, and adequate
power is supplied to your unit.
Safety decals should be read
and understood by all people in
the grain handling area. The ro-
tating blade, fire warning decals
and voltage danger decal must be
displayed on the fan can. The bot-
tom right decal should be present
on the inside bin door cover of
the two-ring door, 24" porthole
door cover and the roof manway
cover.

Autoflow Operation
1. Read and understand the operating manual before trying to operate the
dryer.
2. Power supply should be OFF for service of electrical components. Use
CAUTION in checking voltage or other procedures requiring power to
be ON.
3. Check for gas leaks at all gas pipe connections. If any leaks are de-
tected, do not operate the dryer. Shut down and repair before further
operation.
4. Never attempt to operate the dryer by jumping or otherwise bypassing
any safety devices on the unit.
5. Set pressure regulator to avoid excessive gas pressure applied to burner
during ignition and when burner is in operation. Do not exceed maxi-
mum recommended drying temperature.
6. Keep the dryer clean. Do not allow fine material to accumulate in the
plenum or drying chamber.
7. Use CAUTION in working around high speed fans, gas burners, augers
and auxiliary conveyors which START AUTOMATICALLY.
8. Do not operate in any area where combustible material will be drawn into
the fan.
9. Before attempting to remove and reinstall any propeller, make certain to
read the recommended procedure listed within the servicing section of
the manual.
10. Clean grain is easier to dry. Fine material increases resistance to airflow
and requires removal of extra moisture.
This product is intended for the use of grain handling only. Any other
use is considered a misuse of the product.
Some edges of the product components can be sharp. It is recommended
that each component of this product be examined to determine if there
are any safety considerations to be taken. Any and all necessary personal
protective equipment should be worn at all times when handling, assem-
bling, installing and operation of the product and/or components.
Guards are removed for illustration purpose only. All guards must be
in place before/during operation.
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 ef-
ficient operation and reasonable ac-
cess to components.
Use extreme caution in working
around high-speed fans, gas-fired
heaters, augers and auxiliary con-
veyors, which may start without
warning when the dryer is operat-
ing on automatic control.
READ THESE INSTRUCTIONS
BEFORE OPERATION AND SERVICE
SAVE FOR FUTURE REFERENCE
Continued safe, dependable opera-
tion of automatic equipment de-
pends, to a great degree, upon the
owner. For a safe and dependable
drying system, follow the recom-
mendations within this manual, and
make it a practice to regularly in-
spect the operation of the unit for
any developing problems or unsafe
conditions.
Take special note of the safety pre-
cautions listed above before at-
tempting to operate the dryer.

SAFETY SIGN-OFF SHEET

Autoflow Operation
Power Supply
An adequate power supply and proper wiring are impor-
tant factors for maximum performance and long life of
the dryer. Electrical service must be adequate enough to
prevent low-voltage damage to motors and control cir-
cuits (see Electrical Load Information). In 220V 1-phase
and 220V 3-phase systems, a separate neutral wire is
required for the 120V heater circuit, and should be
connected to terminal #1 in the master heater. Do not
run in conduit with motor power lines.
It is necessary to know the distance from the unit to the
available transformer, and the horsepower of your fan
unit. Advise the service representative of your local power
supplier that an additional load will be placed on the line.
Each fan motor should be wired through a fuse or circuit
breaker disconnect switch. Check on KVA rating of trans-
formers, considering total horsepower load. The power
supply wiring, main switch equipment and transformers
must provide adequate motor starting and operating volt-
age. Voltage drop during motor starting should not ex-
ceed 14% of normal voltage, and after motor is running
Transformer and Wiring Voltage Drop
ELECTRICAL POWER SUPPLY
Dave, any ideas what to put here,if anything?
at full speed, it should be within 8% of normal voltage.
Check Electrical Load Information for HP ratings and
maximum amp loads to properly size wire and fusing
elements. Standard electrical safety practices and codes
should be used. (Refer to National Electrical Code Stan-
dard Handbook by National Fire Protection Association).
It is very important that a Machine To Earth Ground
Rod be installed at the fan. This is true even if there is
a ground at the pole 15 feet (4.572 meters) away. Place
the ground rod that comes standard, within 8 feet
(2.438 meters) of the dryer, and attach it to the dryer
control panel with at least a #6 solid, bare, copper
ground wire and the clamp provided. The grounding
rod located at the power pole will not provide adequate
grounding for the dryer. The proper grounding will
provide additional safety in case of any short and will
ensure long life of all circuit boards, and the ignition
system. The ground rod must be in accordance with
local requirements.
