Roof Damage Warning and Disclaimer

WARNING! BE ALERT!

Personnel servicing fans and

heaters should read this manual.

Failure to read this manual and its

safety instructions is a misuse of

the equipment.

The symbol shown is used to call

your attention to instructions con-

cerning your personal safety.

Watch for this symbol; it points

out important safety precautions.

It means "ATTENTION",

"WARNING", "CAUTION", and

"DANGER". Read the message

and be cautious to the possibil-

ity of personal injury or death.

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 VENTILATION AND/OR

"MAKEUP AIR" DEVICES SHOULD BE PROVIDED

FOR ALL POWERED AIR HANDLING SYSTEMS.

GSI DOES NOT RECOMMEND THE USE OF DOWN-

WARD FLOW SYSTEMS (SUCTION). SEVERE ROOF

DAMAGE CAN RESULT FROM ANY BLOCKAGE

OF AIR PASSAGES. RUNNING FANS DURING HIGH

HUMIDITY/COLD WEATHER CONDITIONS CAN

CAUSE AIR EXHAUST OR INTAKE PORTS TO

FREEZE.

ROOF WARNING, OPERATION & SAFETY

Proper Use of Product

This product is intended for the use of grain

drying only! Any other use is a misuse of this

product. This product has sharp edges! These

sharp edges may cause serious injury. To avoid

injury handle sharp edges with caution and use

proper protective clothing and equipment at all times.

Guards are removed for illustration only. All guards

must be in place before and during operation.

The GSI Group, Inc. recom-

mends contacting your local power

company, and having a representa-

tive survey your installation so the

wiring is compatible with their sys-

tem, and adequate power is sup-

plied to your unit.

Safety decals should be read

and understood by all people in

the grain handling area.

SAFETY

FAILURE TO INSTALL

THERMOSTAT INCREASES RISK OF FIRE IN BIN!

WARRANTIES ARE VOID ON HEATERS INSTALLED

WITHOUT THERMOSTATS.

CAUTION! BE VERY

CAREFUL WHEN

CHECKING OUT 220V OR

460V CONTROL CIRCUIT.

SERIOUS INJURY OR

DEATH MAY OCCUR IF

PROPER PRECAUTIONS

ARE NOT TAKEN.

BE SURE POWER IS

DISCONNECTED AND

LOCKED OUT BEFORE

INSTALLATION. FAILURE

TO DO SO MAY CAUSE

SERIOUS INJURY OR

DEATH

Fuel Warning

Important! Do not use propane tanks which have previously been used for ammonia unless

they have been purged according to procedures of the National L. P. Association.

Be sure fuel supply system complies with all local codes for L. P. gas installations.

DO NOT USE FLAME FOR LEAK TESTING.

Power Warning

Be sure power is disconnected and locked out before installation!

Failure to do so may cause serious injury or death.

Important! Heater must be interlocked with fan for safe operation.

Important! Thermostat must be installed for safe operation.

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 provides the grounding neces-

sary for long life and operation of the solid state

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 previ-

ously 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 GSI

). 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 gal-

lons of water.

2. Fill hole with water.

Proper Installation of the Ground Rod

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

3

7. Ground wire must not have

any breaks or splices. Insu-

lated wire is not recom-

mended for grounding.

Figure 1: 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.

Previously Installed

Units

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 com-

pletely into the ground. This

method of installing the rod

gives a good conductive bond

with the surrounding soil.

1. Check for 220V between points C and F. If no

voltage present, check power at primary disconnect.

2. Check for 220V between points C and D. If no

voltage present, check "J" (thermostat) wires.

(on units with " J " wires)

3. Check for 220V between points C and E. If no

voltage present, replace or reset thermal motor

4. Check for 220V between points F and G. If no

voltage present, replace 1/4 amp fuse.

5. Check for 220V between points F and H. If no

checkout and replace if necessary.

Note: Always check for 220 volts at check points.

110 volts to ground does not necessarily mean

check point is okay. Voltage may bleed through

contactor coil and other similar parts.

Motors used in GSI fan units are all standard

NEMA frame motors and are specially designed for

use in crop drying applications. Most of the replace-

ment parts for these motors are handled by authorized

service stations of the various motor manufacturers.

1. Always disconnect and lock out power before

working on or around fan motor and electrical

components.

2. Malfunctioning electrical components

should be checked by a qualified electrician.

3. For extra motor life, any electric motor

a. Fans setting idle in the summer offer an

excellent place for mud dobbers to build

their nests. A mud dobber nest on the

back of the fan blade will cause the fan

to be out of balance and vibrate.

b. Also, mice have been known to

nest in the back of a blade.

When the fan is

started the centrifugal force kills the mice,

but throws the blade out of balance.
