Discharge line
Temperature at inlet port
determines required length
and diameter.
To minimize the likelihood of a discharge line blockage during
cold climate operation, it is recommended that for discharge lines
exceeding 9 feet in length, a minimum of 3 feet of 1/2-inch thick
closed-cell polyethylene pipe insulation be used at the connection
to the air dryer.
