This document provides installation, operation, and maintenance instructions for HBC(X), PHBC(X), RHBC(X), and CHBC(X) Horizontal Hydronic Fan Coil Units.
These units are horizontal hydronic fan coil units designed for indoor installation, typically above a dropped ceiling. They are designed to provide heating and cooling by circulating either hot or chilled water through a hydronic coil. The fan circulates air over the coil, transferring heat to or from the conditioned space. The units are listed for installation with zero clearance to combustible materials, including the fan coil cabinet, discharge plenum, and connecting ducts.
