Fan/Heater Installation and Operating Instructions
ThankyouforchoosingaTopDrySeries Autoflow.Itisdesignedtogiveexcellentperformanceandservice
for many years.
This manual describes the installation for all standard production TopDry Series 2000 single fan,
multi-fan and 2000 Series Heater Control units. Different models are available for liquid propane or
natural gas fuel supply, with either 1 phase 230 volt or 3 phase 208, 220, 380, 460 or 575 volt
electrical power.
Our foremost concern is your safety and the safety of others associated with this equipment. We want to
keep you as a customer. This manual is to help you understand safe operating procedures and some
problems that may be encountered by the operator and other personnel.
As owner and/or operator, it is your responsibility to know what requirements, hazards, and precautions
exist, and to inform all personnel associated with the equipment or in the area. Safety precautions may be
required from the personnel. Avoid any alterations tothe equipment. Such alterations may produce a very
dangerous situation where SERIOUS INJURY or DEATH may occur.
This equipment shall be installed in accordance with the current installation codes and applicable
regulations, which should be carefully followed in all cases. Authorities having jurisdiction should be
consulted before installations are made.

Safety Precautions
READ THESE INSTRUCTIONS BEFORE OPERATION AND SERVICE
SAVE FOR FUTURE REFERENCE
1. Read and understand the operating manual before trying to operate the dryer.
2.PowersupplyshouldbeOFF for service of electrical components.UseCAUTION in checkingvoltage
or other procedures requiring power to be ON.
3. Check for gas leaks at all gas pipeconnections. If any leaks are detected, 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 maximum 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 can START AUTOMATICALLY.
8. DO NOT operate in any area where combustible material will be drawn into the fan.
9. BEFORE attempting to remove and re-install 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.
Use Caution in the Operation of this Equipment
This dryer is designed and manufactured with operator safety in mind. However, the very nature of a
grain dryer having a gas burner, high voltage electrical equipment and high speed rotating parts, presents
hazardsto personnelwhichcannotbecompletelysafeguarded againstwithoutinterferingwiththeefficient
operation of the dryer and reasonable access to its 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 this manual and
make it a practice to regularly inspect the unit for any developing problems or unsafe conditions.
Take special note of the Safety Precautions on Page 5 before attempting to operate the dryer.
Keep the dryer clean. Do not allow fine material to accumulate in the plenum
chamber or surrounding the outside of the dryer.

2. Safety Decals
The GSI Group recommends you contact your local power company and have a representative survey
your dryer installation, so your wiring will be compatible with their system and you will have adequate
power supplied to your unit.
Safety decals should be read and understood by all people in and around the dryer area. If the following
safety decals are not displayed on your dryer or if they are damaged, contact The GSI Group for
replacement:

Roof Damage Warning and Disclaimer
GSI does not warrant any roof damage caused by excessive vacuum orinternal pressure from fans
or other air moving systems. Adequate ventilation and/or "makeup air" devices should be
provided for all powered air handling systems. GSI does not recommend the use of downward flow
systems (suction). Severe roof damage can result from any blockage of air passages. Running
fans during high humidity/cold weather conditions can cause air exhaust or intake ports to freeze.
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.
