Troubleshooting FAQS

• Check for cause and replace
• Check valve missing or failed / replace or add
• In-correct rotation requiring a reverse of motor wiring
• Confirm operation by: Removing drain plug from discharge silencer to check for air flow or slowly close isolation BFV until PRV opens to confirm blower is operating.
• Check motor amp draws against other units and O&M
• Tighten connection or replace gasket

• Turn off power and proceed to clean impeller chamber
• Have a qualified electrician inspect motor for damage
• Have a qualified electrician inspect motor connections

If you chose not to use the Universal Blower Pac recommended lubricants, you do so at your own risk. Universal Blower Pac will not give approval for any lubricant other than recommended lubricants listed in the O&M Manual. Use oils with rust and oxidation inhibitors, anti-foam additives, and the viscosities listed in the specific blower manual. If not, this could void the manufacturer’s warranty. Do not use oil that contains EP additives, motor oil or detergent oils.

Universal Blower Pac recommends that all piping be completed and the blower system is tested for performance during final installation.

All information pertaining to design performance parameters can be found in the Blower Data Performance page in the O&M Manual.

Grouting serves not only to compensate for surface irregularities between the foundations and machine base, but also to provide a restraint against shifting and to reduce transcendental vibrations generated by the operation of the equipment. Additionally, the grout will not shrink and pull away from the base foot. This ensures that the bolt does not lose tension.

By starting the blower package you assume all liability and responsibility for any possible equipment failure due to improper start-up and or installation. Therefore, if any failures result from improper startup without an authorized technician, the warranty will be void.

Never attempt to control air capacity by means of throttle valve, check valve or butterfly valve in the intake or discharge piping. This will increase the power load on the drive system, increase operating temperatures, and could overload and / or seriously damage the blower. Any attempt to control capacity by these means could void all manufactures warranty considerations. Increasing pressure will also decrease airflow.

Initial break-in lubrication should be changed after the first 500 operating hours. Thereafter, follow the O&M Manual on the specific project. Recommended service intervals are for normal blower operating conditions. Severe operating conditions may warrant more frequent oil changes. Laboratory analysis of lubricant should be used to determine the optimum oil change interval.

Servicing frequency of filter elements is not time predictable. A filter restriction gauge should be installed across the inlet filter. It is also recommended to install a filter restriction switch. This will indicate how much service life of the filter element has been used. In all cases reference the specific filter manufacturers service instructions.  Due to the many types of filters, it is not practical to give specific instructions covering all models and applications. Under normal conditions filters may last 3 to 6 months but could easily need to be replaced as quickly as days in an extremely dirty environment. Filters need to be frequently checked.

It is preferred that lubrication be added by the contractor / owner with the supervision of the certified technician present. This is to ensure proper lubrication and levels are achieved.
