Receiving Inspection

 CAUTION

Do  not  use  the  flow  sensor,  connecting  tubing,  or  damper 

shaft  as  a  lift  point.  Damage  to  the  flow  sensor  or  controls 

may result. 

Prior to removing the shipping material, visually inspect 

the packing materials. There should be a black plastic strip 

wrapped in the clear plastic shrink wrap. If this black plastic 

strip is missing, the shipment may have been repacked by 

the shipper and you should make note of this on the shipping 

documents and inform the delivering carrier. After unpacking 

the terminal, check it for shipping damage. If any shipping 

damage is found, report it immediately to the delivering 

carrier. Store units in a clean, dry location prior to installation. 

Units with controls are not recommended for use in ambient 

temperatures greater than 95°F. For protection of controls, do 

not store in ambient temperatures greater than 135°F.  

Hanging/Installation Requirements

 CAUTION

If  equipped  with  pneumatic  controls,  the  orientation  of  the 

terminal is critical. The pneumatic controls must be mounted 

right side up. The fan powered unit must be level  

or – 10 degrees of horizontal, both parallel to the air flow and 

at the right angle of air flow. The control side of the terminal 

is labeled with an arrow indicating UP. Unless otherwise 

noted,  most  analog  and  digital  controls  may  be  installed  in 

any orientation. 

Check with the local Daikin representative for verification. 

 CAUTION

The equipment is heavy and mounted in the ceiling. Use 

caution and follow OSHA or SMACNA installation guidelines.

The Fan Powered Air Terminal should be suspended from the 

building structure in a horizontal plane with the two bottom 

access panels facing downward. Do not obstruct the bottom 

access panels or control panel enclosure cover. At both 

ends of the air terminal unit, a three inch wide mounting lip 

provides easy installation of either trapeze type hangers or 

hanging straps.  

•  Use the required mounting support method prescribed for 

the rectangular duct per the job specifications, or 

•  Use hanging straps located at both ends of the fan 

powered unit (

Figure 1

), or 

•  Use trapeze mounts located at both ends of the fan 

powered terminal unit (

Figure 2

), or 

•  Fan powered air terminals may be suspended with 

optional hanging brackets and hanger rod. (

Figure 3

The Fan Powered Air Terminal is not suitable for outdoor use.
