INSTALLATION (cont.)
Ducting With Typical Drop Ceiling
Use a 10.0 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.
Make sure the ducts are secured in order to absorb vibration from the unit.
Avoid bending the duct suddenly and have air ducts travel in a strait line for
improved performance.
• Following filed supplied hardware requires:
• Insulated 10.0 inch diameter ducts
• Return air grill with filter for evaporator air intake
• Diffuser for cold air
• Maximum external static pressure, 0.40 IWG (100 Pa) for evaporator duct and
grills
CAUTION: Do not operate CM12 without the filter installed on the
return air grill.
