STEP 1: Remove FFU form shipping carton and inspect for any damage
NOTE: Ensure the HEPA/ULPA filter has been safely stored in a vertical position, per carton label, until ready for use,
STEP 2: Raise the unit through the ceiling grid at an angle unitl its above the grid
STEP 3: Lower unit onto the backside of the tees
STEP 4: Secure the unit to the overhead structure using the eyebolts located on the back of the unit.
STEP 6: Adjust and level the unit so that it rests on the tees and there is adequate compression on the gaskekt to warrant a tight seal.
Ensure that ceiling grid is properly gasket/sealed to prevent infiltration of unfiltered air from the ceiling plenum into the room side. Above steps are manufacturer's suggested hanging techniques, always make sure to follow all local building codes, including seismic, where applicable.
STEP7: Refer to Factory Lable to determine which speed controller is on the unit and use the following table for appropriate reference page for the particular speed controller on your unit.
NOTE: Depending on unit ordered, speed controller will be mounted on the unit itself, or, if a wll-kit option was selected, shipped loose for field installation
SPEED CONTROLLERS INSTALLATION & OPERATION
STEP 8A: Locate pre-installed electric box for wall-mounted speed controller.
STEP 9A: Wire speed controller according to wiring diagram found on page 57. Wall-mounted speed controller will be wired in series with the motor.
NOTE: WIring should be carried out by a certified electrician and meet national and local electrical codes.
STEP 10A: Attach the wall-mounted countrols faceplate to the electrical bos using the screws provide.
STEP 11A: WIre the unit according to appropriate wiring diagram. If Power Cord(PC) option is selected, simply insert plug end into electrical socket.
STEP 12A: If using RSR filter, refer to page 11for filter installation instructions.
NOTE: Ensure that the space is clean, free of debris, and ducts are cleaned and ready for operation prior to installation of filter.
STEP 13A: ENSURE proper voltage is hooked up to unit.
STEP 14: proceed to controls and balancing section on page 42.
NOTE: Clockwise rotation will increase airflow, counter-clockwise rotation will decrease airflow
NOTE: If unit is ducted, refer to Technical Note: Balancing Ducted Units on page 44pf this manual
STEP 8B: Locate pre-installed electrical box for wall-mounted speed controller.
STEP 9B: Wire speed controller according to wiring diagram (found on page 58-60.) Motor speed controller will have color codes wires and must be wired to the matching colors on dthe wall-mounted portion.
STEP 10B: Attach the wall-mounted controls faceplate to teh electrical box using the screws provide.
STEP 11B: wire the unit according to appropriate wiring diagram. If Power Cord option is selected, simply insert plug end into electrical socket.
STEP 12B: ID usin RSR filter, refer to page 11 for filter installation instructions.
STEP 13B: Ensure proper Voltage is hooled up to tyhe unit.
STEP 14B: Proceed to contros and balancing section
If unit does not have the wall kit option, proceed to STEP11C.

BACnet Fow Controller (BFC) Installation and Operation
Sample line string:
STEP 8D: Wire unit according to appropriate wiring diagram.If Power Cord(PC)option is selected, simply insert plug end into electrical socket.
NOTE: Polarity is important and must be observed. It is also vital that the 24 VAC common side of the transformer be Earth Ground.
STEP 9D: Hook up applicable BACnet, and/or local Building Automation System(BAS) according to wiring diagram found on page 58-60. For multiple units, use provided cable to daisy chain units together.
STEP 10D: Wire the unit according to the appropriate wiring diagram. If power cord option is selected, simply insert the plug end into the electric socket.
STEP 11D: If using RSR filter, refer to page 11 for installation instructions.
STEP 12D: Ensure proper Voltage is hooked up to the unit.
STEP 13D: Proceed to controls and balancing section on page 42.
