guide, mark 2 holes on ple-
num side wall appproximately
24" to right of transition cen-
tered up and down in plenum.
2. Drill air switch filter hole 5/8"
diameter for snug fit. Drill tem-
perature sensor hole 5/8" or
larger to accommodate mounting
nut.
3. Mount Box to Bin using (4)
self drilling screws

4. Caulk between housing and side-
wall to seal.
1. Mark location on transition
one (1) foot up from the bot-
tom (entrance collar) and cen-
tered in the transition.
2. Drill or knock out 7/8" diam-
eter hole on marked location.

IMPORTANT! When
mounting (2) heaters on a
bin it is imperative that
they be situated as
illustrated in this drawing. Plenum thermostat
must be to the right of
master heater and master
heater must be to the
right of slave heater.

HEATER INSTALLATION
Heater Unit
1. Be sure fan unit is installed and
wired to meet local codes. Be
sure equipment is well grounded
(see page 10).
2. A separate neutral is required
for 120 volt heater circuit in 220
volt 1PH and 3PH fan units. For
460 volt fan units a separate 120
volt power supply or transformer
is required.
3. Run 5-wire black cord from
heater unit to fan unit and se-
cure to fan.
4. Orange and red wires should be
connected in series with coil in
fan. When contacts in heater be-
tween these wires open fan

shuts down. Recommended wiring is shown in Figure 2.
5. Black and white wires should be connected to a fused 120V
power supply as shown. Green wire should be connected to
ground in fan. Heater should have power, even with fan off.
Figure 3: Secondary heater wiring diagram.
SECONDARY HEATER UNIT
1. Secondary heater unit runs as a slave of heater
unit #1 and requires no plenum temperature
sensor.
2. Run (2) 20 gauge (minimum) wires from sec-
ondary heater unit (slave) to heater unit #1
(master).
3.
Connect wires as shown in Figure 3.
4. Third heater unit may also be added to system.
If adding third unit, run connections to master
unit #1 and connect them in parallel with sec
ondary heater unit.

HEATER INSTALLATION
Machine To Earth
Ground
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.
(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.
Series 2000 Vane Axial Heater
Figure 4: Use a
#6 or approved
size bare copper
ground wire.
Install a 5/8"
diameter 8' long
copper-clad
ground rod, 2'
away from the
foundation and 1'
below the surface
of the ground or
in accordance
with local
requirements.
Proper Installation Of The Ground Rod
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.
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
conductive bond with the surrounding soil.
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.
Previously Installed Units
It is recommended that previously installed units be checked to see
that a machine to earth ground has been installed by an electrician.

Standard electrical safety prac-
tices and codes should be used
when working with a heater.
Refer to the National Electric

Liquid Propane Models
1. L.P. models are designed to run on liquid pro
pane with liquid draw from the propane tank.
Avoid using propane supply tanks that have been
used for vapor draw for long periods of time.
When using liquid draw systems any moisture
that may be present in tank or lines may freeze
when system is used in cold weather. To avoid
this situation, purge the system with methanol.
2. Run proper size line (see specification on page
7) to liquid pipetrain on heater. Have a qualified
gas service person inspect installation to be sure
that everything is installed according to local
codes and ordinances.

Installing Optional Humidity Sensor
1. Humidity sensor should be mounted 6-8"
right of the airswitch/temperature sensor
box. See Figure A.
2. Using sensor as a guide drill or knock-out
7/8" diameter hole in the center of the
plenum on the bin sidewall. If you are
using sensor to sense drying air humidity.
3. Insert pipe nipple from sensor housing
through hole in side wall and use selfdrilling screws to mount to sidewall.

4. Do not caulk sensor box openings on side
of box, they are for air escape.
