•
Too much resistance of duct will decrease air-flow-rate, which will lead to capacity of
unit decreased.
•
Total duct length ideally should be no more than 5m and 3 x 90 degree bends or the
maximum static pressure should be within 25Pa.
•
For unit air outlet with duct, when unit operating, condensate will be generated around
outside of duct. please pay attention to the drainage work, we suggest to wrap the thermal
insulated layer around outside of the duct.
