supply/return/by-pass hoses (3-hoses) via field
provided pipe insulation. Insulating the piping will stop

piping package. This insulation must be field provided
and field installed.
•

protection of the waterside economizer. This must be
field provided and installed.

package. The filter rack is located in the unit’s
packaging along with the filter.
