The unit will operate most quietly and efficiently when located
where the shortest possible duct run and minimum number of
elbows will be needed.
Use a roof cap or wall cap that has a built-in damper to reduce
backdrafts.
Plan to supply the unit with proper line voltage and appropriate
power cable.
