3.  Installing the Ceiling Components: FFUs, Light, Duplex Cable, and Ceiling Panels 

 

 

 

To prevent damage to the delicate filter medium, always exercise care when handling 

Fan Filter Units! 

Handle FFUs by the frame only; do NOT apply pressure to the filter face. 

 

CAUTION 

A.

 

Verify that each FFU speed control is set at “Medium.”

 Install the FFUs by carefully lowering each into the 

appropriate opening in the ceiling support frame (see following page for location). Each module should fit snugly 

against the ceiling grid frame to form a tight seal. No fasteners are necessary to hold these modules in place.  

 

B.

 

Install the light modules by carefully lowering each into the appropriate opening in the ceiling support frame. The 

light fixture should fit snugly against the ceiling grid frame to form a tight seal. No fasteners are necessary to hold 

it in place.  

 

C.

 

Control Panel Switchbox is installed to the right of the access door. The power cable extends from the switch 

box, through the vertical upright and out at the top of the ceiling joist. Verify that this cable is attached to the 

connector labeled “To Switch Connection” on the Power Distribution Module. 

D.

 

The duplex power outlet is installed inside the buffer room. To complete the electrical connection, run the power 

cable that extends above the duplex receptacle to the Power Distribution Module, and complete the connections 

as shown below and on the following page. 

Figure 3: Ceiling Fixtures  –

 Including
