Vektor Installation
The
figures below illustrates four common methods used to install Vektor systems. Methods used to attach a
Vektor unit are dependent on local codes, roof construction design and roof construction materials. Consult an
architect or structural engineer for proper means of attachment.

Plenum Drainage Piping / Trap Detail (By Others)
There are multiple locations for pipe connections, one on each plenum section and another on each tubular fan
housing. Each drain should be properly connected to a drainage system to ensure proper disposal of any water
or condensate that may occur.
• Installed piping to have a downward angle to allow for drainage
• Fill trap to recommended level before start-up
