5. INSTALLATION  
Standard electrical safety practices and codes should be used when working with a fan. Refer  
to the National Electric Code Standard Handbook by the National Fire Protection Association. A  
qualified electrician should make all wiring installations.  
ALWAYS DISCONNECT AND LOCK OUT POWER BEFORE  
WORKING ON OR AROUND FAN  
Roof Fan Description  
GSI roof exhaust fans are designed to mount on structures with sloping roofs, and with a flat roof  
surface at least as large as illustrated in Figure 4A & Figure 4B on page 7. The fans will mount  
between the ribs of standard tapered roof sheets on round steel bins without cutting the ribs,  
which keeps the strength of the roof sheet intact. The 18" .5 HP roof fan is shipped completely  
assembled, and will mount on a roof slope of 30 degrees. The 24", 2 HP roof fan is shipped with  
the roof adaptor and rained unassembled, and it is also designed to mount on a 30 degree roof  
slope.  
18" and 24" Roof Fan Location  
The roof fans should be equally spaced on the bin roof circumference. When installed, the roof  
fan should be positioned as far up the roof slope as the tapered ribs of the bin roof sheet will  
allow.  
The roof fan location should be selected to provide a rigid mounting for the fan. For bins  
with an inner roof structure, the roof fan should be anchored to the inner roof structure.

5. INSTALLATION  
18" Roof Fan Mounting  
The roof fan can be installed in the roof sheet before assembling the roof, or after the roof is  
assembled. Locate roof fan so that inner roof structure does not interfere with installation.  
The fan is secured by bolts that must be fastened from the inside of the bin roof, and therefore  
the assembly should be made before the side walls are erected.  
1. Using the loose flange from the fan assembly as a template, position the desired roof fan  
location, allowing for 1" minimum between the roof sheet rib and the flange (See Figure 5A).  
Mark the sixteen (16), 3/8" mounting holes, and elliptical fan mounting hole.  
2. Drill the sixteen (16), 3/8" holes and cut out the elliptical hole. Use the caulk provided, which  
is specified as a seal for metal sheets in an outdoor application, and apply along the in side  
edge of the drilled holes on the bin roof sheet (See Figure 5A).  
Figure 5A The 18" Template Location on the Roof Sheet (Left), and  
the Caulking Location on the Roof Sheet (Right).  
3. Place the roof fan into the elliptical hole from the outside of the roof sheet inward. On the  
side of the roof sheet that will be inside the bin, position the loose mounting flange over the  
fan tube. Using the sixteen (16) 5/16" x 3/4" bin bolts with the neoprene washer head to the  
outside of the bin, secure the fan, roof sheet and flange with the 5/16" nuts provided.

5. INSTALLATION  
24" Roof Fan Mounting and Assembly of Fan, Adaptor and Rain Hood  
The roof fans, adaptor and rain hood can be installed in the bin roof sheet before assembling the  
roof or after the roof is assembled. The fan is secured by bolts that must be fastened from the  
inside of the bin roof, so the assembly should be made before the sidewalls are erected.  
1. Assemble the roof sheet mounting template as shown in Figure 5C.  
Figure 5C 24" Roof Fan Template Placement on the Roof Sheet.  
Figure 5D 24" Roof Fan Adaptor and Template Parts Breakdown.  
2. Place the roof sheet adaptor mounting template at the appropriate location of the roof fan.  
Move the template as far up the roof sheet as possible, but allow for 1" minimum clearance  
between the roof sheet rib and bottom of the template on each side.

3. Drill two corner holes and bolt template in place.  
4. Drill the remaining 11/32" mounting holes identified on the template.  
Figure 5E The Rainhood Preassembly.  
5. Mark a cutting line 3/4" inside the template. Then remove template. Drill through the mark,  
cutting a hole in the roof sheet (See Figure 5F).  
6. Preassemble the adaptor section parts of the roof fan. Loosely bolt the adaptor left side and  
right side to adaptor top. On all components, bolts are to be installed with the head on the  
fan housing exterior.  
7. Caulk along the bolt hole line where the adaptor flange will mount to the roof sheet.  
8. Bolt the adaptor section to the roof sheet along with the support angles MIS-6703 (template)  
under the roof sheet (See Figure 5G). Tighten the adaptor to the roof sheet with template  
bolts.

9. Form a lip up around the inside of the adaptor opening by peening up the edge of the roof  
sheet extending past the inner edge of the roof adaptor.  
10. Loosely bolt the rainhood top plate, rainhood right side and rainhood left side together.  
11. Bolt the fan housing to the adaptor (See Figure 5H).  
Figure 5H The 24" Roof Fan Exhauster and Rainhood.  
12. At this time the optional 90° deflector may be preassembled.  
13. Bolt deflector assembly to MIS6674 sub-assembly for noise deflection. (See Figure 5I).  
Figure 5I The 24" Roof Fan Exhauster with Optional 90° Deflector.  
14. Bolt rainhood to fan housing or optional 90° deflector if installed.  
15. Support optional 90° deflector adequately down to bin roof structure to prevent exhauster  
or roof damage due to flexure of deflector and exhauster.  
16. The roof fan location should be selected to provide a rigid mounting for the fan. For  
bins with an inner roof structure, the roof fan should be anchored to the inner roof  
structure.  
17. The fan housing top plate is provided for access to the motor for electrical installation, and  
a knock out is provided in the fan side for the wire access. Depending on when you have  
your electric connections made, the motor could be wired before Step 12 or the fan could  
be wired later by removing the fan housing top plate.

5. INSTALLATION  
24" Roof Exhauster Reinforcement Kit  
Figure 5J  
1. Refer Page 11 for the 24" roof adaptor template and mounting, and the 30° Roof Manual  
PNEG-030 for the roof channel assembly.  
2. Install the roof support channels in the ribs of the upper panel where the exhauster is to be  
mounted.  
3. Install the template and cut exhauster parts as specified on Page 11.  
4. Utilize the upper MIS-6811 and lower MIS-6805 reinforcement supports to support the  
exhauster. Mount reinforcement under the top support plate MIS-6706 and bottom support  
plate MIS-6707 on the bottom surface of the roof panel.  
5. After placing the supports, field drill the attachment clip at the required locations in channels  
CRP-4793.  
6. Some field cutting or bolting of components may be necessary due to variables in the roof  
exhauster mounting equipment.  
7. The MIS-6804 is designed primarily around mounting into the upper roof of a GSI  
commercial bin/silo. Field fabrication of supports may be necessary in other brands of  
bins/silos.  
8. A pair of adjustable brace assemblies are included in this kit to brace the exhauster unit to  
the roof ribs on the upper side of the roof. Attach the brace to the roof exhauster unit and  
then attach the other end to a roof rib (via a 5/16" bolt). This should attach to the exhauster  
near the rainhood mounting angle point.  
9. The adjustable brace consists of one center tube (LS-6615) and two end tubes (LS-6616).  
The end tubes go inside the center tube and attach one end tube to the top of the extension  
rail. Adjust the other end tube so the bottom of the flattened tube reaches the roof rib. Field  
drill four 5/16" holes through both center and end tubes and bolt together using  
1/4" x 1.1/2" bolts and nuts. This will keep the adjustable brace from slipping.

7. ELECTRICAL INSTALLATION  
Electrical Installation of the Fan  
The electrical installation must be performed by a certified electrician in accordance with the  
appropriate national and local electrical codes.  
WARNING  
ANY VIOLATION OF ELECTRICAL WIRING CODES COULD JEOPARDIZE THE  
AIRSTREAM WARRANTY.  
Check the type of electrical service present, and make sure the fan to be wired is manufactured  
to operate on the electrical service. The table on page 7 entitled “Fan Model Specifications”  
indicates the electrical service the fan is designed to utilize in the column labeled “Motor Phase  
and Voltage”. The electrical service must match this specification.  
The components to connect the electrical service to the fan need to be sized for the electrical  
service present. The charts below illustrate the sizing information for single phase 230 volt, three  
phase 230 volt and 460 volt respectively. Use the appropriate information and size the following  
electrical service components:

Transformer  
The transformer size for the fan only is indicated in a KVA rating. Example: For a 24" fan the first  
chart would be used. The KVA rating for the 2 horse power motor is 3.5 KVA. This KVA rating is  
for the fan only. Your electrician will need to add the KVA requirements for the other electrical  
components of the system in sizing the transformer.

7. ELECTRICAL INSTALLATION  
Fan Disconnect  
A disconnect for the fan needs to be sized to handle the recommended fusetron size.  
Example: For a 24" fan the first chart on Page 17 would be used, and the fusetron size is 30  
AMP. Install the fusetron recommended in the disconnect. A circuit breaker can be used,  
however, the circuit breaker or any fuse used must be a time delay type to allow the initial starting  
inrush current to the fan.  
Conductor Size for the Fan Disconnect to Fan Wiring  
The conductor size for the fan needs to be sized according to the distance between the fan and  
disconnect. Example: For a 24" fan located 200' from the disconnect use the first chart  
on Page 17 to determine the conductor size to be a 14 AWG. The proper size wiring must be  
used to make sure a voltage drop does not occur.  
Fan Motor Controller  
Size the fan motor controller according to the motor ratings for a convenient control location as  
follows:  
Motors with internal overload protection will require a magnetic contactor to control fan  
operation. Motors without overload protection will require a magnetic starter with overload  
protection to control fan operation.  
Single Phase  
A 3-wire system should be provided for fans to be operated on single phase power. The three  
wires consist of the two current conductors and a ground. The current carrying conductors are  
wired per the diagram on the motor. The ground is secured to the motor frame. On 2 HP  
explosion proof motors thermostat wires are provided with the motor, and must be connected to  
the fan motor magnetic controls.  
Three Phase  
A 4-wire system should be provided for fans to be operated on three phase power. The four wires  
consist of three current carrying conductors, and a ground. The current carrying conductors are  
wired per the diagram on the motor. The ground is secured to the motor frame. On 2 HP  
explosion proof motors thermostat wires are provided with the motor, and must be connected to  
the fan motor magnetic controls.  
When installing electrical service for explosion proof motors make sure all conduit and  
connectors exposed to the conditions of the motor are rated for the Class II group F and G  
location of the motor.  
Installation Check  
When the fan is completely assembled and wired the unit needs to be checked for proper  
rotation. Provide power to the fan controls and start the fan momentarily. Make sure the fan blade  
rotates to exhaust air from the bin. If the blade is rotating the wrong direction, have your  
electrician correct as follows:  
Single Phase System  
With the power OFF at the fan disconnect, the motor lead wires at the fan motor need to change  
as indicated on the motor to reverse the blade rotation. The unit then needs to be rechecked for  
proper rotation.

7. ELECTRICAL INSTALLATION  
Three Phase System  
With the power OFF at the fan disconnect, exchange the location of the current carrying  
conductors at terminal L1 and L3 (See Figure 7A) of the magnetic controls. The unit will then  
need to be rechecked for proper rotation.  
Figure 7A Connecting the Fan Rotation for Three Phase.  
Always check current local, state and national codes on electrical requirements before installing  
any electrical equipment.  
Transformer size is based on the current draw from the fan only. Your electrician will need to add  
the KVA requirements for the other components of the system in sizing the transformer.  
Copper wire (rated 75°F) is sized for the fan service. The wire size from the transformer to the  
disconnect service will be determined from the fan, and the other electrical equipment  
requirements.

8. OPERAT  
Before Starting Fan  
When starting the fan for the first time, check the following:  
1. With the power OFF, rotate the fan blade to make sure it revolves easily, and does not rub  
on the venturi or fan tube.  
2. Check all the fasteners to make sure they are tight. If any are loose, check for proper  
clearance and retighten.  
3. With the power OFF, check all electrical connections to make sure they are tight. Inspect  
the current carrying wires to make sure they are not grounded. Make sure the fan and  
disconnect are grounded. All control enclosure covers and access doors should be secured  
in place.  
4. Refer to the wiring diagram on the motor, and make sure the motor is wired correctly.  
Starting the Fan  
The roof exhaust fans should operate anytime the supply fans operate. The roof fans can  
operate independently of the supply fans just to provide ventilation of the attic space, but this  
requires that vents be used in the roof to provide an open area.  
18" fan............4 square feet per fan  
24" fan...........10 square feet per fan  
Fan Shut OFF  
When shutting the fan down for the season, shut OFF the power at the fan disconnect rather than  
at the fan controls to provide additional protection from unauthorized personnel operating the  
fan, and potential damage to the fan from a lightning strike.  
Off Season Operation and Maintenance  
During the off season, the fan blade should be allowed to turn freely. The fan should operate for  
approximately 30 minutes every three weeks. This keeps the fan lubricant more evenly  
distributed within the bearing cavity, and dries out any condensation that could be in the motor.  
Fan Service  
When servicing the fan, switch power OFF at the fan disconnect switch. Activate power only  
when a check is made. The following items will help you to pinpoint a possible malfunction of the  
fan unit and explain the corrective action to take.  
If the motor controller is turned ON and nothing happens, check the following:  
1. Make sure power is available to the fan unit.  
2. Check the motor thermostat (if present) to determine if the thermostat is open or closed. If  
the thermostat is open, take the motor to your local authorized service center. When  
checking the thermostat, make sure the motor has time to cool, if hot.  
3. If power is available to the motor and it does not run, remove the motor and take it to an  
authorized motor service center for repair or replacement.

8. OPERATING INSTRUCTIONS  
If the fan just hums when turned ON, check the following:  
1. Check to make sure that all leads of your power source have voltage present. If fan unit is  
not receiving power on all leads, check for a blown fuse, broken wire or loose connection.  
2. Check to see that all contact sets are closing. If one leg of the supply voltage is not available  
to the motor it will hum.  
3. If power is available at all motor leads, and the motor still hums, it should be taken to an  
authorized service center for repair or replacement.  
If the fan starts and operates for awhile and then shuts OFF, check the following:  
1. Check the supply voltage. Voltage should be within +/-10% of rated voltage. For example,  
a motor rated at 230 volt should operate in a voltage range of 207 to 253 volt.  
2. Check the supply wire size required for the fan unit.  
3. Check the load on the main circuit to make sure other items on it are not overloading the  
fan circuit.  
4. Check the amperage of the fan, if the unit is pulling above name plate amperage, take the  
motor to an authorized service center.
