5. Installation All single phase motors and the 1/2 HP explosion-proof 3 phase motor are supplied with automatic overload protection. The remaining 3 phase motors do not have internal motor protection. Motors rated as explosion-proof (EX PRF) meet class II group F and G of the National Electric Code (NEC).

5. Installation 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.

Installation 18" Roof Fan Mounting (Continued) Figure 5D The 18" roof exhauster fan in relation to the roof sheet. 24" Roof Fan Mounting and Assembly of Fan, Adaptor and Rainhood The roof fans, adaptor and rainhood 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.
5. Installation 24" Roof Fan Mounting and Assembly of Fan, Adaptor and Rainhood (Continued) Figure 5F 24" Roof fan adaptor and template parts breakdown. 2. Place the roof sheet adaptor mounting template at the appropriate location for 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 (2) corner holes and bolt template in place. 4.
5. Installation 24" Roof Fan Mounting and Assembly of Fan, Adaptor and Rainhood (Continued) 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 5H.) 6. Pre-assemble 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.

Bolt deflector assembly to sub-assembly (MIS-6674) for noise deflection. (See Figure 5K.) Figure 5K The 24" Roof Fan Exhauster with Optional 90° Deflector 14. Bolt rainhood to fan housing or optional 90° deflector if installed. 15.
5. Installation 24" Roof Fan Mounting and Assembly of Fan, Adaptor and Rainhood (Continued) 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.
5. Installation 24" Roof Exhauster Reinforcement Kit Figure 5M 24" Roof Exhauster Reinforcement Kit Detail (MIS-6804) 1. Refer to Page 16 for the 24" roof adaptor template and mounting and the 30° roof manual PNEG-030 for the roof channel assembly. 2.

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. Any violation of electrical wiring codes could jeopardize the airstream warranty. CAUTION Check the type of electrical service present and make sure the fan to be wired is manufactured to operate on the electrical service.
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 23 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.
7. Electrical Installation 3 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 re-checked for proper rotation. Figure 7A Correcting the Fan Rotation for 3 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.
8. Operating Instructions 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.
8. Operating Instructions If the fan just hums when turned ON, check the following: 1. Check to make sure that all leads of the 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.
