HEATER INSTALLATION
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 away.
This ground needs to be as close to
the fan as possible, but no more than
8 feet away. The ground rod should
be connected to the fan control panel
with at least a #6 solid bare copper
ground wire, or in accordance with
local requirements. The machine to
earth ground provides additional
safety if there is a short. It also pro-
vides the grounding necessary for
long life and operation of the solid
state circuit boards used on control
circuits and the electronic ignition
systems.
Machine To Earth
Ground
Dig a hole large enough to hold 1
or 2 gallons of water. Work the
ground rod into the earth until it is
completely in the ground.
It is recommended that previously installed units be checked to see
that a machine to earth ground has been installed by an electrician.
(Ground rods and wires are not supplied by Airstream). It is recommended that
the rod not be driven into dry ground. The following steps ensure proper ground
rod installation:
1. Dig a hole large enough to hold 1 to 2 gallons of water.
2. Fill hole with water.
3. Insert rod through water and jab it into the ground.
4. Continue jabbing the rod up and down, the water will work its way
down the hole, making it possible to work the rod completely
into the ground. This method of installing the rod gives a good

5. Connect the bare copper ground wire to the rod with the proper
ground rod clamp.
6. Connect the bare ground wire to the fan control boxes with a
grounding lug. See figure 4.
7. Ground wire must not have any breaks or splices. Insulated
wire is not recommended for grounding.

OPERATING PROCEDURE
The control panel display showing initial start up.
All safety and high limit switches are checked upon
power up. If a safety or limit is open, the control dis-
plays it. The control cannot operate with a safety switch
error, and the fan cannot turn on with an error condi-
Standard electrical safety practices and codes should
be used when working with a heater. Refer to the
National Electric Code Standard Handbook by
the National Fire Protection Association. A quali-
fied electrician should make all wiring installa-
tions.
Power Up
The controller locks up with the main display alter-
nating between a "FAN" and "ON" message. This
may be bypassed by depressing and holding the
"FAN BYPASS" switch (lower right switch). Nor-
mal operating procedure should be to power up the
controller with the fan off.
If multiple heaters are tied together, and the
master detects that the slave fan is on (the air
switch stuck?), the master will lock up display-
ing "SLA ERROR". This condition may be by-
passed with the "FAN BYPASS" switch.
tion. There is no way to bypass an error condition. It
must be fixed. (See errors on page 21)
The air switch is also checked on power up.
The air switch must indicate no airflow. This is
necessary to check the function of the air switch.
However, if the operator forgets and turns the fan
on before the controller has been powered up,

OPERATING PROCEDURE
Normal Operating Displays With Heater Not Running
The heater display with fan on (airflow).
When drying is not occurring, and the limit
or error condition is corrected, the display returns
to its normal output. This is not the case with an
error or limit condition during the drying opera-
tion. This causes the display to lock up in the er-
ror display mode. This is to keep the display
locked up with the condition illuminated. ( see
section on "Running the Dryer" for mode expla-
nation on page 17).
The main display shows the plenum temperature. If
the dryer has not been running, the display should
show outside temperature. The control is preset at
the factory to display temperature in centigrade or
fahrenheit.
"AIRFLOW" or "NO AIRFLOW" is displayed
if air is flowing or not flowing. "RX TX" (receive,
transmit) is displayed if multiple heaters are con-
nected.
All safeties or high limits are continuously
checked during the off mode. A limit switch open,
or any other error condition will cause the display
to show the limit or error condition.

Setting Gas Pressure
Starting The Dryer
*Temperatures are fahrenheit.
After heater power is turned on, the fan must be
turned on. Attempting to start the dryer without the
air switch indicating there is airflow will cause an air-
flow alarm to go off when the start switch is depressed.
The airflow alarm is simply the entire display going
blank, and the "NO AIRFLOW" message flashing for
a few seconds. The display must show "AIRFLOW"
before the dryer can be started.
To start the dryer, just push the "START" switch.
The first message to come up will be the "PURGE"
message--the drying process begins with a 10 sec-
ond purge.
When multiple heaters are connected together,
drying may be started from any heater control.

16
Series2000VaneAxialHeater
17. Press the "PROGRAM TEMPERATURE" but-
ton to change the high limit set point. Press it
again to change the "CYCLE SET POINT". (hi-
lo units only)
18. Decrease the "CYCLE SET POINT TEM
PERATURE" until the heater cycles to low
flame. (hi-lo units only)
16. When the burner ignites the display should read
"HI-FLAME " at the left of the display. Loosen
the nut on the main regulator and turn screw in, to
increase pressure and out to decrease pressure.
The pressure gauges should be set at 10-15 lbs.
for LP units, or 4-6 lbs.. for natural gas units. (use
the charts on the following pages to set pressure)
19. Open or close the low cycle ball valve until
the gas pressure is 3-5 lbs. for LP, or 1-2 lbs.
for natural gas. (hi-lo units only)
20. Increase the cycle set point to return to high
flame. (hi-lo units only)
21. Watch heater run several minutes to make
sure it cycles between hi and lo flame or on
and off properly.
22. Hi-flame pressure should be adjusted so ple-
num reaches cycling temperature easily.
23. Adjust pressure on on/off units so that unit is
on approximately 75% of the time.

Series2000VaneAxialHeater
Adjusting the Air Pressure Switch
1. Air pressure switch must be adjusted so
that it will activate with lowest level of
grain that will be dryed in bin.
2. Put grain in bin to level desired (low).
3. With heater on and fan off display on
heater should read "no airflow".
4. Start fan. Heater display should now read
"airflow".
5. If display does not read "airflow" remove
cap from adjustment port and slowly turn
screw counter clockwise until display does
read "Airflow". Figure C
6. Shut fan off display should read "no air
flow" when fan gets to half speed. If not
repeat step 5.

Adjusting the vaporizer coil on a liquid propane model. The top photo
shows the setting in, and the bottom photo shows the coil out.
Adjusting The Vaporizor
The display will indicate "FLAME"
when flame is sensed. If no flame
is sensed, the "FLAME" message
will be off. The display indicates
what part of the cycle it is in. If the
unit is a hi-lo dryer, the display will
indicate whether it is in the "HI-
FLAME" or "LO-FLAME" part of
the cycle. (See "programming set
points" page 21 for setting the hi-lo
flame temperature). If the tempera-
ture is above the high temperature set-
ting, the flame will be off, the
"FLAME" message will be out and the
display will be flashing "OFF-
CYCLE".
If the flame is shut off because
of the humidity sensor (humidistat),
the display flashes "OFF-CYCLE
HUMIDISTAT".
Running The Dryer
1. Vaporizer should be adjusted so
the vapor pipetrain runs warm
to the touch (100°-120°F).
2. Loosen 5/16" bolt on adjust-
ment bracket.
3. Swivel vaporizer away from
flame if running too hot, closer
to flame if too cold.
4. Move vaporizer only 1" at a time
and allow a few minutes for
tem perature to equalize.
5. Tighten 5/16" bolt and watch
heater run for several minutes
to verify adjustment.
