INSTALLATION
Installation
•
Place the unit so that it can be monitored and con
-
trolled from all sides at all times.
•
Ensure that sufficient space is provided for maintenance.
•
Ensure that all liquid-carrying components, connec
-
tions, lines, and all electrical connections and lines are
easy to access.
•
Ensure that the pipe connection points are visible.
NOTICE
Lightning protection rods beside the unit are recom-
mended.
If the units are intended to be put into a dual or quad
position, the height of the louver section in the single box
sizes are increased to ensure sufficient air intake. See
Figure 1 to Figure 4 and Table 1.
WARNING
Refer to the submittal package for specific unit infor
-
mation.
LOCATION LAYOUT
Ensuring optimum performance of the unit with unob
-
structed airflow is the responsibility of the installing
contractor. In order to not compromise the performance
of the unit, locations on open rooftops or at ground level
with no obstructions such as walls or adjacent buildings
are optimal.
When optimal locations are not possible, units must be
positioned such that the discharge air is either level or
higher than these adjacent obstacles. It is imperative that
the location allows for unrestricted airflow into each unit
and that there is no recirculation of the saturated dis
-
charge air. It is also advisable that the discharge air is not
in the direction of, or in close proximity to, any air intake
location for the building’s ventilation system.
