LAYOUT

This phase should have been completed prior to placing your order. If you don’t have a plan or wish to

review it again, please consult with your professional engineer, designer and/or installer. You may also

contact your ZOO Fans’ representative or ZOO Fans directly if you require assistance.

Remember, the number of ZOO Fans required for the job, as well as where they are hung, will depend on a

number of variables, some of which are:

•Ceiling height, as well as the overall volume of air the fans need to move in order to achieve the

targeted level for turnover of air in the facility every hour (a good target for destratification is

100% turnover every hour)

•The availability of a sturdy and secure anchor point for attaching the fan

•Obstructions above the ceiling such as sprinklers, lighting, and hanging cables

•Obstructions that may block a clear path for airflow from the fan to the floor, such as

merchandise/inventory racks, equipment, and other mechanical systems

•The location of existing HVAC diffusers and returns

•A straight line between the intake and outtake to ensure the ducting is straight to maximize airflow

•A desire to create air movement at a specific work station, machine or other locale

Ask the electrician who will be installing the fans to review the following section to be sure your layout is a

good one when evaluated against existing wiring and electrical equipment. Ask the contractor who will be

hanging your fans to review your layout for ease and safety of installation, as well as compatibility with

existing mechanical systems and all applicable codes. If the installer(s) have any questions about where to

locate your fan(s) or how to install them, please contact either your ZOO Fans’ representative or ZOO Fans.
