INSTALLATION (cont.)
Ducting With Typical Drop Ceiling
All hardware is field supplied.
CAUTION: Do not operate the unit without the filter installed on the
return air grill.
1. Use a 12 inch diameter insulated duct with low friction and air resistance.
The duct should be bent in a large radius. If the bending radius is less than
15.0 inch (381 mm), then use vanes or guides to reduce air resistance.
2. Make sure the ducts are secured in order to absorb vibration from the unit.
Avoid sharp bending on the duct and have air ducts travel in a straight line for
improved performance.
Field supplied hardware requires:
• Insulated 12 inch diameter flexible ducts
• Return air grill with 12 inch flange and filter for the room air intake
• Diffuser with 12 inch flange for the cool air outlet
