INSTALLATION

Step 1 — Check Jobsite — Installation, operation and maintenance instructions are provided with each unit. Before unit start-up, read all manuals and become familiar with the unit and its operation. Thoroughly check out the system before operation. Complete the inspections and instructions listed below to prepare a unit for installation. See Table 1 for unit physical data.

IMPORTANT: This equipment is designed for indoor installation ONLY. Extreme variations in temperature, humidity and corrosive water or air will adversely affect the unit performance, reliability and service life.

The 50VS units are designed for indoor installations. Units are typically installed in a floor-level closet or a small mechan- ical room. Be sure to allow adequate space around the unit for servicing. See Fig. 1-5 for unit dimensions.

CAUTION

To avoid equipment damage, do not use units as a source of heating or cooling during the construction process. The mechanical components and filters used in these units quickly becomes clogged with construction dirt and debris which may cause system damage.
