may result in property damage.
BE ALERT!
Danger!
Personnel operating or working
around electrical equipment
should read this manual. This manual must be
delivered with equipment to its owner. Failure
to read this manual and its safety instructions is a
misuse of the equipment.

INSTALLATION
Be Sure Power Is Disconnected And
Locked Out Before Installation!
Failure To Do So May Cause Seri-
ous Injury Or Death.
Checklist Before
Installing Electric Heater
1. One of the most important factors for installa-
tion is providing adequate power to run the unit.
Under sized wire can lead to voltage drop and
can cause overheating of power leads and poor
performance. Therefore, it is necessary to know
the distance from the unit to an available trans
former and the horsepower of your fan unit.
These two factors will determine the size of wire
needed for efficient operation. See Fan Specifi-
cations on the following page.
2. Each electric heater circuit should be wired
through a fused or circuit breaker disconnect
switch.
3. Refer to the Heater Specifications on page 7 for
the recommended slow blow fuse or breaker size
1. Be sure that the disconnect and the fan are well
grounded. See machine to earth ground page 9.
2. Check all fasteners on heater elements and other
bolted items to make sure they are tight. If
any are loose, check for proper clearance and
retighten. They may have loosened in shipping.
3. Heater should be bolted solidly to fan and tran-
sition.
4. Check and retighten all electrical connections.
They may have loosened in shipping.
5. Make all input power connections to heater as
shown on page 8.
Important! Heater Must Be Interlocked To Fan
Or Connected To An Air
Proving Device. In Event Of Fan Failure
Heater Must Be Shutdown.
Installation
Instructions
to use when installing your particular Heater.
4. Standard electrical safety practices and codes
should be used. Refer to National Electric Code
Standard Handbook by National Fire Protection
Association.
5. A qualified electrician should make all electri-
cal wiring installations.

Downwind Heater Electrical Installation
Be Sure Power Is
Disconnected And Locked Out
Before Installation!
Failure To Do So May Cause
Serious Injury Or Death.
1. Make field connection of heater
power cord to 5 amp fuse block
in fan as shown in Figure 4.
2. Make field connection of ther-
mostat wires in heater control
box. Thermostat wires are
tagged HI-LIMIT INTER-
LOCK in heater box.

Electric Heater INSTALLATION
Proper Installation Of Ground Rod
Machine To Earth
Grounding
good contact with the surrounding soil, making a proper ground.
5.Connect the bare, copper ground wire to the rod with the
proper ground rod clamp.
6. Connect the bare ground wire to control panel with a grounding lug.
7. Ground wire must not have any breaks or splices. Insulated
wire is not recommended for grounding applications.
(Ground rods and wires are not supplied by Manufacturer). It is recom-
mended that the rod not be driven into dry ground. Follow these instruc-
tions for proper 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 jabing the rod up and down. The water will work its
way down the hole, making it possible to work the rod com-
pletely into the ground. This method of installation assures
Previously Installed Units
It is recommended that previously installed units be checked to see
that a machine to earth ground has been properly installed by an elec-
trician.
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.
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 very important that a Ma-
chine To Earth Ground Rod be
installed at the fan. The ground
rod 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. The ground-
ing rod located at the power pole
will not provide adequate ground-
ing for the fan. The proper
grounding will provide additional
safety if there is a short and will
ensure long life of all circuit
boards used on control circuits,
and the ignition system. The
ground rod must be in accordance
with local requirements.

Electric Heater
OPERATION
Start Up
1. Turn thermostat knob to its warmest position.
2. Set heater switches to ON position. Red light
should be lit.
3. Watch thermometer on thermostat housing.
When temperaturereaches desired level turn
thermostat knob slowly to the left until heater
lights go out.
Remember: Electric heaters normally give no more
than 5-15 degrees temperature rise.
4. Observe the heater as it runs through a few cycles
to make sure thermostat is set correctly.
Service
All Electric Heater Units are designed and built to with-
stand use in the most severe environments. Take time
out at least once a year to go over the whole unit and
make sure everything is in working order. Preventive
maintenance can save time and money if done on a regu-
lar basis.
1. Always disconnect and lock out the power be-
fore working on or around fan motor and elec-
trical components.
2. Malfunctioning electrical components should be
checked by a qualified electrician.
3. Heater elements should be cleaned yearly to
avoid excess dust and dirt build up. Excessive
build up on heater may cause heater to perform
poorly and reduce the life of the heater elements.
