† Model Numbers end in “-Z” for units with Series Flow piping configuration. Series Flow units may require additional coil connections and will require
crossover piping. Model numbers will include “R” for units with Low Sound Fan(s) and “S” for units with an option that negates CTI certification.
†† Heaviest section is the coil/fan section.
* Gallons shown is water in suspension in unit and piping. Allow for additional water in bottom of remote sump to cover pump suction and strainer
during operation (12” would normally be sufficient).
When a remote sump arrangement is selected, the spray pump, suction strainer and associated piping are omitted; the unit is provided with an
oversized outlet to facilitate drainage to the remote sump.
Unit dimensions and coil connections may vary slightly from catalog. See factory certified prints for dimensions, quantity of coil connections, and
piping configuration. Coil connections are 4” bevel for weld (BFW). Other connection types such as grooved for mechanical coupling or flanged are
also available as options.
