Installation
1. Using air switch box as a
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
largerto accommodate mounting
nut.
3. Mount Box to Bin using (4)
self drilling screws
4. Caulk between housing and side-
wall to seal.
Air Switch Box Assembly
1. Mark location on transition
one (1) foot up from the bot-
tom (entrancecollar) and cen-
tered in the transition.
2. Drill or knock out 7/8" diam-
eter hole on marked location.
3. Install transitionhi-limit using
supplied self drilling screws.

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

Series 2000 Downwind Heater HEATER INSTALLATION
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

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.
2. Run (2) 20 gauge (minimum) wires from sec-
ondary heater unit (slave) to heater unit #1

unit #1 and requires no plenum temperature
sensor.

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.

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
beconnected to the fan controlpanel
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.
(Groundrodsand wires arenotsupplied by Airstream).Itisrecommended that

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

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.
Figure 4: Use a
#6 or approved
size bare copper
ground wire.
Install a 5/8"
diameter 8' long

foundation and 1'
below the surface
of the ground or

with local
requirements.
