PRE-INSTALLATION
The safe installation and operation of equipment supplied by ZOO Fans is the responsibility of the system designer, installer,
maintainer, and operator (collectively, the “User”). The need for protective safety accessories to meet company standards,
applicable codes, and the requirements of the Occupational Safety and Health Act (“OSHA”) must be determined by the
User since safety requirements may vary depending on the location and application of the equipment.
The elements of a successful installation consist of:
1. Good layout of fans, wiring, and controls
2. Hanging the fans where they’ll be most effective and convenient to control
3. Completing the electrical hook-up
4. Start-up and commissioning
5. Conducting all work in a safe manner consistent with all relevant codes and regulations
PARTS ENCLOSED
If you ordered multiple fans, be sure to keep the components of each fan together.

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 installed, will depend on a number of
variables, some of which are:
•Ceiling height, as well as the overall volume of air the fan(s) need to move in order to achieve the targeted
level for turnover of air in the facility every hour. A good design target for destratification is 100% turnover
of the volume of air every hour.
•The availability of sturdy and secure anchor points for attaching the fan
•Obstructions, such as merchandise/inventory racks, lighting, and other mechanical systems
•The location of existing HVAC diffusers and returns
•A desire to create OR avoid air movement at a specific work station, machine or other locale
Ask the electrician who will be installing the wiring for 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 directly. A copy of this installation guide can also be found at www.zoofans.com.

INSTALLATION
BEFORE INSTALLING THE FAN IN THE CEILING,
FOLLOW THESE ASSEMBLY INSTRUCTIONS
ASSEMBLY
STEP 1: Attach Motor to Diffuser
1. Place the diffuser on a soft surface or support it by the outer edges all the way around (such as placing it over the
opening of a box) so the jet ball is not damaged during this operation
2. The motor will come pre-assembled with the adapter ring attached. Place the motor down over the diffuser as
shown below, and install the adapter ring onto the intake side of the jet ball diffuser.
3. Align the motor so the pre-installed wire comes straight out, toward the side where the power supply wire from
the circuit will be supplied
Combination Diffuser
Motor
Plenum
Place the motor over the back of the diffuser so the adapter
ring attaches to the intake side of the jet ball diffuser

4. Tighten the band clamp on the adapter ring
STEP 2: Install the Plenum
1. Place the plenum over the diffuser, aligning the notches in the plenum with the mounting studs on the diffuser
2. Install and tighten two wing nuts on the studs at the bottom of the plenum on the side with the electrical opening
3. Install and tighten the two wing nuts on the opposite side (see arrows, below)
Leave the remaining wing nuts off –they will be installed at a later step.

ELECTRICAL WIRING
STEP 1. Remove the cover plate from the Junction Box
1. Remove the two screws—one at each side on the top—that hold the cover plate and remove it:
STEP 2. Secure the Fan Wire and Attach the Junction Box to the Mounting Plate
1. Place the wire from the junction box on the motor through the hole in the side of the plenum
2. Put the wire through the strain relief that is already attached to the mounting plate, with the screws
facing in toward the fan and secure the strain relief by tightening the two screws:

STEP 3. Attach the junction box mounting plate to the plenum
1. Slide the junction box mounting plate onto the two screws already in place, and tighten
2. Install two additional (8-32) 1/2" machine screws (provided) and tighten to secure to plenum
Install two remaining screws, provided, and
tighten to secure mounting plate to plenum

SECURING THE FAN
STEP 1: Prepare Hanging System before Installing Fan in Ceiling
The IC20 Drop-In includes a four (4) wire Gripple® hanging system to support the unit on the drop ceiling grid. This system
relieves additional weight load on the existing ceiling frame to avoid sag or unleveled portions of the ceiling, and also
provides a safety system to secure the fan independently of the ceiling.
WARNING: The Tethers MUST be installed properly to ensure safe operation of your ZOO Fan.
1. Place the eyelet end fixings at the end of each Gripple wire over the mounting studs on BOTH SIDES of the plenum
(two per side), and secure with remaining wing nuts as shown below:
INSTALLATION TIPS:
•Only uncoil enough of the Gripple wire to attach the end fitting to the stud
•Tape the remainder in a coil on the top of the plenum so it’s out of the way while lifting the fan into the ceiling
FOR BEST RESULTS:
•Place duct tape along the outside, bottom edge of the plenum to seal between the plenum and the diffuser in order
to maintain optimum air circulation

STEP 2: The Fan Unit is Ready to be Placed in the Ceiling Frame
1. Be sure to place the fan so the side with the electrical mounting plate is facing toward the power supply. Lifting
the fan unit by the diffuser, carefully place it in the designated 2’ x 2’ ceiling grid by angling it through the opening
and setting into place. When angled, the assembled unit it can be lifted through a 2’ x 2’ opening.
2. Uncoil each Gripple wire that is attached to the fan
3. Place a Gripple fitting on each wire
4. Loop each wire over a Truss, I-beam, support beam or other suitable anchor point
5. Push end of wire back into Gripple fitting, repeat for all wires
6. Adjust wires so there is no slack

WIRING THE FAN TO THE POWER SUPPLY
STEP 1: Prepare Power Supply Wire in Ceiling
1. Prepare the wire from the power supply and secure it to the J-Box using the strain relief
2. The fan utilizes a double-insulated motor that does not require grounding. Terminate the grounding wire from
the power supply to the metal junction box.
STEP 2: Wire the Fan
Using the black and white wires from the fan that are secured by the mounting plate, wire the fan
to the power supply as follows:
STEP 3: Replace the Cover on the Junction Box
Install and tighten (2) screws, one on each side at the top:
TO POWER SUPPLY
TO FAN MOTOR
TERMINATE GROUND WIRE TO
THE METAL JUNCTION BOX

FAN SHOULD NOW BE INSTALLED PROPERLY AND READY FOR OPERATION
WIRING THE CONTROLLER (Optional)
•Electrical connection should be made according to the wiring diagram (see wiring diagram on following page)
•Proper grounding of the controller is required for safety and proper operation
•Multiple fans may be wired in parallel to one controller; please contact ZOO Fans for detailed instructions
•Ground wire must be bonded at each location where metal boxes are used
CAUTION: An incorrectly installed controller can result in component damage or reduction of the fan’s life. Wiring or
application errors such as under-sizing the controller, incorrect or inadequate AC supply, or excessive ambient
temperatures may result in a malfunction of the fan system. Verify correct voltage and phase before beginning installation!
CAUTION: Fans should only be used with manufacturer supplied controller. Do not use fan with other speed control
devices!
