V ektor -CD Dir ect or Belt Drive The V ektor -CD fan is a side inlet centrifugal blower with a high plume dilution nozzle designed for laboratory exhaust systems.
Remove any accumulations of dirt, water , ice or snow and wipe dry before moving to indoor storage. T o avoid “sweating” of metal parts allow cold parts to reach r oom temperature. T o dry parts and packages use a portable electric heater to get rid of any moisture build up.
3 V ektor -CD Centrifugal Laboratory Exhaust ® REMOVING FROM ST ORAGE As fans are r emoved from storage to be installed in their final location, they should be protected and maintained in a similar fashion, until the fan equipment goes into operation.
4 V ektor -CD Centrifugal Laboratory Exhaust ® Curb Installations Greenheck supplies gasketing material for all multi- section curbs and/or plenums. Install gasketing prior to bolting split curbs and or plenums together .
5 V ektor -CD Centrifugal Laboratory Exhaust ® Riser Installation Check curb or structural supports for levelness. Both must be level to ensure pr oper drainage from plenum and fan(s). For side inlet fans, remove panel at end of plenum. This opening is the designed connection spot for user connected ductwork from building.
6 V ektor -CD Centrifugal Laboratory Exhaust ® Plenum Installation The figures depicted illustrate thr ee common methods used to install V ektor -CD bypass plenums. Methods used to attach a V ektor unit are dependent on local codes, roof construction design and r oof construction materials.
7 V ektor -CD Centrifugal Laboratory Exhaust ® Fan Installation Fan Housing Installation If the windband is shipped attached to the fan housing or if the windband is secured to the fan housing prior to mounting to the plenum, the fan / windband assembly should be lifted by the lifting lugs located on the fan housing.
8 V ektor -CD Centrifugal Laboratory Exhaust ® Plenum and Fan Drainage Piping and T rap Detail (by others) There ar e multiple locations for pipe connections, one on each plenum section, and another on each tubular fan housing located at the bottom of the scroll.
9 V ektor -CD Centrifugal Laboratory Exhaust ® Disconnect is mounted to fan housing. T ransformer is mounted to bypass air plenum near isolation damper actuator motor . For systems that ship un-assembled because of physical size, this connection at disconnect from transformer must be field installed.

13 V ektor -CD Centrifugal Laboratory Exhaust ® Bearing Replacement Both drive bearings are accessible fr om the ground on all V ektor -CD fans. Whether direct or belt driven, the bearings, along with other serviceable drive components (belts, motors, sheaves) are accessible by removing the motor cover panel.
14 V ektor -CD Centrifugal Laboratory Exhaust ® Problem Cause Corrective Action Excessive noise Wheel rubbing inlet Adjust wheel and/or inlet cone. Tighten wheel hub or bearing collars on shaft. V -belt drive Tighten sheaves on motor/fan shaft. Adjust belt tension.
