GENERAL
The Series 100 Single Packaged units are designed for outdoor installation. When select-
ing a site for installation, be guided by the following conditions:
• Unit must be installed on a level surface.
• For the outdoor location of the unit, select a place having a minimum sun exposure
and an adequate supply of fresh air for the condenser.
• Also avoid locations beneath windows or between structures.
• Optional condenser coil protection should be used for seashore locations or other harsh
environments.
• The unit should be installed on a roof that is structurally strong enough to support the
weight of the unit with a minimum of deflection. It is recommended that the unit(s) be
installed not more than 15 feet from a main support beam to provide proper structural
support and to minimize the transmission of sound and vibration. Ideally, the center
of gravity should be located over a structural support or building column.
•
Location of unit(s) should also be away from building flue stacks or exhaust ventila
-
tors to prevent possible reintroduction of contaminated air through the outside air
intakes.
• Be sure the supporting structures will not obstruct the duct, gas or wiring connec-
tions.
• Proper service clearance space of 6 feet around the perimeter of the unit, 8 feet on
one side for coil servicing, and 12 feet to any adjacent units is required to eliminate
cross contamination of exhaust and outdoor air, and for maintenance tasks such as
coil pull and cleaning. No obstructions should be above the condensing unit section.
LOCATION
Of the many factors that can effect the location of equipment, some of the most important
to consider are Structural, Acoustical and Service clearances. Proper attention should be
made at the design stage to ensure proper structural support. In cases where equipment
is being replaced, be aware of building design to insure support is adequate for the ap
-
plication.
The next most important consideration in applying single package units equipment is that
of sound from the equipment. Special care should be made to keep the single package
unit away from sound sensitive areas such as conference rooms, auditoriums and execu-
tive offices and any other room that may have potential for tenant occupancy. Possible
locations could be above hallways, mechanical or utility rooms.
Finally, service clearances should be maintained in single package unit design to insure
safe access to the unit. Unit clearances are designed so that technicians have enough
space between units, building walls, and edges of building to gain access safely. In cases
where space is limited, please call your local Johnson Controls representative for addi-
tional information.
