general Receiving Unpacking Be careful not to damage or deform any parts of the blower when removing it from the packaging container. All the packaging material should be kept in the event the blower needs to be returned. Handling Handling of the blower should be performed by trained personnel and be consistent with all safe handling practices. - Page 5 general Never operate a blower with a non-ducted inlet and/or discharge.

Page 6: Installation
installation Installation Vibration Before any mounting method is selected, the user should be aware of the ef- fects vibration will have on the blower, motor and other parts. Improper blower installation can cause excessive vibration causing premature wheel and/or motor bearing failure, that is not covered under warranty. Vibration eliminator pads, springs or bases should be properly installed to prevent any blower vibration from transmitting to the foundation, support structure or ducting. -

Safety Guards Cincinnati Fan offers guards, as optional, to keep your blower in compliance with OSHA safety regulations. These include inlet or discharge guards. Any blowers built with high temperature construction, a “heat slinger guard” is standard. -

The blower shaft/bearing/coupling guard (if included) should only be removed for inspection before start-up and during inspection or maintenance but only after the power to the motor has been turned off and locked out. The blower shaft/bearing/coupling guard must be replaced before the power is turned back on. - Page 10 installation that should be replaced with grease fittings to perform re-lubrication. These motors, or any motor with grease fittings, should be lubricated in accordance with the motor manufacturers recommendations. Lubrication frequency depends on the motor horsepower, speed and service. Be sure you use compatible grease and Do not over grease.

If the operating conditions of the blower are to be changed (speed, pressure, temperature, etc.) consult Cincinnati Fan or our sales office in your territory to determine if the unit will operate safely at the new conditions. -

maintenance Do not over grease the blower bearings. Generally, 1-2 shots should be enough. Use a hand-operated grease gun at no more than 40 psi. If possible, carefully lubricate the blower bearings while the blower is running. Lubrication frequencies are based on the fan bearings operating in a clean and dry environment from -20°F (-29°C) up to 120°F (49°C). -
Page 18: Vibration
Make sure you reinstall the wheel so the proper wheel-to-inlet clearance is maintained. Failure to do this will affect the blower’s airflow (CFM), and/or static pressure (SP) capabilities and ef- ficiency. Consult Cincinnati Fan or our local sales office for your area for assistance if necessary. Vibration As mentioned previously in this manual, excessive vibration can cause prema- ture motor failure that could lead to catastrophic failure of the blower. -
Page 19: Blower Shaft Or Bearing Replacement
Blower Shaft and Bearing Replacement: The blower shaft and bearings for Cincinnati Fan blowers are carefully selected to match the maximum load and operating conditions for each specific blower model. If the instructions in this manual and those provided by the bearing manufacturer are followed, you should not need to replace the bearings for many years. - Page 20 maintenance 15. When replacing the bearings, we strongly recommend that the blower shaft and blower/motor coupling also be replaced. However, if you intend to use the same blower shaft, file down all the setscrew marks on the shaft. 16. Install new bearings onto the new blower shaft or onto the original shaft. Be sure the bearing locking collars are facing each other and the set screws are in line with each other.
- Page 21 maintenance 32. While rotating the blower shaft, lubricate blower bearings with fresh grease per Blower Bearing Lubrication instruction in this manual. 33. Install new set screws into the wheel, or taper-lock hub bolts into the hub. Do not use old screws or bolts. 34.
