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.
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.

LEGEND
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.
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.
