This may cause objects to get pulled into the unit and objects to be propelled rapidly from the discharge. The discharge should always be directed in a safe direction and inlets should not be left unguarded.

2 Any object pulled into the inlet will become a projectile capable of causing serious injury or air is allowed to move through a non-powered fan, the impeller can rotate, which is referred to as windmill-ing. Windmilling will cause hazardous conditions due to unexpected rotation of components. Impellers should be blocked in position or air passages blocked to prevent draft when working on and power loss inside rotating components will cause them to be a potential burn hazard. All components should be approached with caution and/or allowed to cool before contacting them for certain lighting conditions, rotating components may appear stationary. Components should be verified to be stationary in a safe manner, before they come into con-tact with personnel, tools or to follow these instructions could result in death or serious attachment of roof mounted fans to the roof curb as well as the attachment of roof curbs to the building struc-ture must exceed the structural requirements based on the environmental loading derived from the applicable build-ing code for the site.

All contact points (indicated by WXYZ) are to have a gap less than the tolerance shown in the table. When the pulleys are not the same width, the allowable gap must be adjusted by half of the difference in width. Figure 3 illustrates using a car-penter s square to adjust the position of the motor pulley until the belt is parallel to the longer leg of the the fan into the wall opening and secure with lag screws, anchor bolts, or other suitable fasteners. Always mount belt drive wall fans in order that the motor base is below the fan shaft. WiringNOTICE! Correctly label the circuit on the main power box and always identify a closed switch to promote safety ( , red tape over a closed switch).

5 All wiring should be in accordance with local ordinances and the National Electrical Code, NFPA 70. Ensure the power supply (voltage, frequency, and current carrying ca-pacity of wires) is in accordance with the motor the wiring diagram in the disconnect switch and the wiring diagram provided with the enough slack in the wiring to allow for motor move-ment when adjusting belt tension. Some fractional motors have to be removed in order to make the connection with the terminal box at the end of the Fans1.

Store it in its original shipping crate and protect it from dust, debris and the the wheel several revolutions every three to five days to keep a coating of grease on all internal bearing mounted to a wall require a different wall opening size than fans mounted in wall collars or wall housings. For specific dimensions, refer to the submittal drawing for the specific fan InstallationTo prevent damage to the fan during shipping, motors 5 HP and larger, and extremely heavy motors (cast iron or severe duty) are shipped loose and must be field mounted by bolting the motor on the motor mounting plate in the existing slots. The motor should be mounted in order that the motor plate is between the fan shaft and the motor Remove the motor plate mounting bolts and motor Remove the motor mounting bolts from the motor Mount the motor to the motor plate aligning the appropriate Place the motor plate on the power assembly and reinstall the mounting and Pulley InstallationBelt tension is determined by the sound of the belts when the fan is first started.

7 The belts will produce a loud squeal, which dissipates after the fan is operating at full capacity. If belt tension is too tight or too loose, lost efficiency and damage can occur. Do not change the pulley pitch diameter to change ten-sion. The change will result in a different fan Loosen the motor plate adjustment nuts on motor base and move motor plate in order that the belts can easily slip into the grooves on the pulleys. Never pry, roll, or force the belts over the rim of the pulley. 2. Adjust the motor plate until proper tension is reached. For proper tension, a deflection of approximately 1/4 per foot of center distance should be obtained by firmly pressing the belt. See Figure Lock the motor plate adjustment nuts in place. 4. Ensure pulleys are properly aligned.

Adjust and tighten as a schedule for inspecting all parts of the fan. The frequency of inspection depends on the operating conditions and location of the fan. Inspect fans exhausting corrosive or contaminated air within the first month of operation. Fans exhausting con-taminated air (airborne abrasives) should be inspected ev-ery three months. Clean the PROPELLER and air inlets if ma-terial build-up is excessive. Excessive build-up can cause imbalance and failure of the PROPELLER . Regular inspections are recommended for fans exhausting non-contaminated air. It is recommended the following inspections be con-ducted twice per year. Inspect bolts and setscrews for tightness. Tighten as necessary Inspect belt wear and alignment. Replace worn belts with new belts and adjust alignment as needed. See Belt and Pulley Installation, on page 2 Bearings should be inspected as recommended in the Conditions Chart, page 5 Inspect for cleanliness.
