 Ducted Installations – Rear Duct Kit
1. Ductwork may be attached to the discharge only, or to both the
discharge and return adapters.
2. The unit is capable of operating with 100 equivalent feet of total
ductwork, or 50 equivalent feet for both the discharge and return
ducting, for the rear and the front of the cooling unit. Elbows or bends
will reduce this length. Use a duct sizing program to determine the total
equivalent feet of a specific duct routing design, or consult the
manufacturer for recommendations.
3. The “High” fan speed setting is recommended for long duct runs and as
ambient temperatures rise. The “Low” fan speed should never be used
in a ducted application.
