Safety Alert Symbol
GSI DOES NOT WARRANT ANY ROOF DAMAGE CAUSED
BY EXCESSIVE VACUUM OR INTERNAL PRESSURE FROM
FANS OR OTHER AIR MOVING SYSTEMS. ADEQUATE VEN-
TILATION 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. RUN-
NING FANS DURING HIGH HUMIDITY/COLD WEATHER
CONDITIONS CAN CAUSE AIR EXHAUST OR INTAKE
PORTS TO FREEZE.
ROOF WARNING, OPERATION & SAFETY
Thank you for choosing a GSI product. It is de-
signed to give excellent performance and service
for many years.
The principal concern of The GSI Group, Inc.
("GSI") is your safety and the safety of others asso-
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.
As owner and/or operator, it is your responsi-
bility to know what requirements, hazards and
precautions exist, and to inform all personnel as-
sociated with the equipment, or who are in the
dryer area. Avoid any alterations to the equip-
ment. Such alterations may produce a very dan-
gerous situation, where serious injury or death
may occur.
Humidistat-Thermostat Operation
WARNING! BE ALERT!
Personnel operating or working around
electric fans should read this manual.
This manual must be delivered with the
equipment to its owner. Failure to read
this manual and its safety instructions is
a misuse of the equipment.

Humidistat-Thermostat SAFETY ALERT DECALS
The GSI Group, Inc. recommends
contacting your local power company,
and having a representative survey your
installation 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 bottom 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.
If a decal is damaged or is miss-
ing contact:

GENERAL INSTALLATION
INSTALLATION INSTRUCTIONS
Figure 1: 24" is the approximate distance from the edge of the transition to the edge of the humidistat installation.
1. The Humidistat-Thermostat should be
mounted on the side of the bin wall between the
foundation and the drying floor. It should be
installed approxi mately 24" from the right side of
the transition as shown.
3. Caulk the top and sides of the plastic housing
using roll caulking supplied with the unit. Do
not caulk the bottom side of housing so mois
ture can escape.
4. Carefully insert sensing probes through bin wall
and secure housing to wall using self-drilling
screws provided. Be careful not to overtighten
screws. Damage to housing could result.
5. Make wiring connections to heater as shown
in heater owners manual.
Standard electrical safety practices and codes should
be used when installing the Humidistat-Thermostat.
Refer to the National Electric Code Standard
Handbook by the National Fire Protection Asso-
ciation. A qualified electrician should make all
wiring installations.
ALWAYS DISCONNECT
AND LOCK OUT POWER
BEFORE WORKING ON OR
AROUND HEATER
2. Use the template on page 17. With these
instructions, drill only the holes necessary for
your particular model. (Note: For humidistat to
operate properly optional cutout must be used.)

Humidistat-Thermostat INSTALLATION OF HI-LO THERMOSTAT
Figure 2: Placement of the Top Dry Hi-Lo Thermostat.
The Hi-Lo Thermostat is designed for use with
the GSI Top Dry Crop Dryer units. It comes with
one thermostat which is adjustable and cycles the
heater from high to low flame. The Hi-Lo Ther-
mostat also comes with a thermometer for moni-
toring the plenum temperature.
2. Use the template on page 17. With these
instructions, drill only the holes necessary
for your particular model.
3. Apply rope caulk to sides and top of plastic
5. Connect the black and white wires to the ter-
minals marked bin hi-limit (3rd and 4th
terminal bottom left hand terminal strip) on
fan and heater safety circuit board.
6. Connect the green and red wires to the ter-
minals marked cycle (8th and 6th terminal bot-
tom left hand terminal strip) on fan and
heater safety circuit board.
1. Locate the mounting position of the thermostat
as shown in the diagram below.
INSTALLATION INSTRUCTIONS
housing. Leave bottom open to let moisture es-
cape.
4. Secure housing to sidewall using self-drilling
screws supplied. Be careful not to over-
tighten. Overtightening may cause the hous-
ing to crack.

4. Use the equilibrium moisture chart be
low as a guide for setting the humidistat.
3. Set the humidistat to the desired relative hu-
midity level you want to maintain under
your drying floor. The heater will cycle on
above this relative humidity, and off when
this level is reached.
1. Set bypass switch to the "HUMIDISTAT ON"
position. This setting allows the unit to run based
on temperature and humidity.
2. Set the thermostat (Humidistat-Thermostat units
only) to the maximum temperature desired. This
allows the thermostat to funciton as a highlimit
control only. See the above temperature control
for setting the thermostat.
5. Monitor the thermometer on the thermostat
housing. When the thermometer comes up
1. Turn the fan unit on and let it run 3 to 5 minutes to
equalize temperature under the bin.
2. Set bypass switch to the "HUMIDISTAT OFF"
position. This setting allows the unit to run based
on temperature only.
3. Rotate the thermostat knob clockwise to the
warmest position.
4. Open the gas valves to the heater, and turn the
heater on . Set heater gas pressure to a moder-
ately high setting (5 to 10 PSI).
7. Watch the unit run through several cycles and
make any final adjustments. (Note: The unit should
be on approximately 80% of the time. If not
adjust gas pressure).
8. Significant changes in outside air temperature
may require readjustment of gas pressure.

to the desired temperature, slowly turn the ther-
mostat knob counter-clock-wise until the
heater cycles off.
6. If the unit does not reach the desired temperature,
gradually increase the gas pressure until the tem
perature rises to the desired level.

8. Significant changes in outside air temperature
may require readjustment of gas pressure.
Note: If temperature of lo-flame exceeds thermo-
stat settings (above normal outside temperatures)
unit will cycle from lo-flame to off. (Top Dry units will
shut down completely)
1. Remove mounting screws from the thermostat
housing and remove the housing from the bin
wall.
2. Carefully remove the back panel from the hous
ing. (It may be necessary to cut caulking).
The Airstream Humi-
distat- Thermostat
is mounted on the
lower right side of
the grain bin's
transition. This al-
lows for easy ser-
vice and opera-
tion.
OPERATION & SERVICE
1. Turn fan unit on and let it run 3 to 5 minutes to
equalize temperature under the bin.
2. Rotate the thermostat knob clockwise to
warmest position.
3. Open gas valves (including lo-fire valve) to
the heater and turn the heater on. Set heater
gaspressure to a moderately high setting. (5
to 10 PSI)
4. Monitor the thermometer on the thermostat
housing. When the thermostat comes up to
desired temperature, slowly turn the most at
knob counter-clockwise until heater cycles to
lo-flame.
GSI Thermostats are designed and built to withstand
the harsh conditions usually found in drying bins.
A yearly preventative maintenance inspection may
extend the life of your heating controls many years.
3. Blow out any dust or dirt that may have collected
inside the housing.
5. Replace the back panel and caulk the corners to
help seal the unit.
6. Reinstall the unit on the bin wall.

gradually increase the gas pressure until the tem-
perature rises to desired level.
6. Adjust the lo-fire valve so that the temperature
drops until the unit cycles back to hi-flame.
7. Watch the unit run through several cycles and
make any final adjustments. (Note: The unit
should cycle approximately two times per
minute. If not adjust gas pressure).
4. Inspect the wiring for any loose connections,
or rodent and insect damage.
