  • Page 66 3. Installation As illustrated in Figure 1, the Airtech 3BA blower can be installed in any physical configuration. CAUTION! Regenerative blowers can have surface temperatures in excess of 320° F. To avoid burns or other physical injury, take care to avoid contact with the surfaces of the blower during and immediately after operation.
  • Page 67 CAUTION! Design your piping system to avoid unnecessary pressure loss, which may significantly affect the operation of any regenerative blower. Contact your Airtech representative for assistance in designing and configuring an appropriate piping system for your application. For alternation between vacuum and pressure in any application, changeover valves are available.
  • Page 68 3. A magnetic motor starter should always be used to connect the motor to the power supply. It is advisable to use thermal overload motor starters to provide maximum protection for the motor and wiring. All cabling used on starters should be secured with good quality cable clamps.
  • Page 69 4. Start-up CAUTION! Do not start the blower motor more than 10 times in one hour. If multiple and frequent start-ups are required by your application, install a minimum run timer in the motor control circuit to avoid decreased motor life and possible fire due to over-starting of the motor.
  • Page 70 5. Maintenance and Servicing WARNING! Be sure the power supply is disconnected and locked out before attempting to do any maintenance on the unit.
