the pilot holes are located in the top of the cabinet. On a
downflow configuration, they are located in the floor of the
cabinet. See the installation drawing provided with your unit
for pilot hole locations.
2.2.1
Conditioned Space
Certain steps should be taken to minimize the effects of
the environment surrounding the conditioned space. This is
especially important for critical/precision room preparation
(computer rooms/labs) requiring close tolerance control of
temperature and humidity. The conditioned space should be
well insulated and include a vapor barrier. The installer should
ensure that the proper insulation rating is used based on
the design of the space, which was the basis for the system
selected. The following table is a recommended minimum
R-value (thermal resistance) to ensure optimum equipment
operation.
The vapor barrier is the single most important requirement for
maintaining environmental control in the conditioned space.
The vapor barrier in the ceiling and walls can be a polyethylene
film. Concrete walls and floors should be painted with a rubber
or plastic based paint. Doors and windows should be properly
sealed and a door sweep used to minimize leakage. Outside or
fresh air should be kept to a minimum (as it adds to the cooling,
heating, dehumidification and humidifying loads), while
maintaining the requirement of the Indoor Air Quality (IAQ)
standard. Lack of these steps can cause erratic operation,
unstable room control and excessive maintenance costs.
2.3
Mounting/Placement
CyberOne EC systems that are not ducted are designed to
be located in the conditioned space. Ducted units may be
located either inside or outside the space to be conditioned
but are designed to supply air to only one room. They have
a compact footprint, which allows the units to be placed in a
corner or between cabinetry. It is recommended to position
the unit to obtain optimum air circulation.
NOTE:
These units use welded frame construction for unit
rigidity. The system is designed to be installed on a roof
curb, which is provided by others and ducted into a singular
space to be conditioned. Ensure the curb is sealed to
prevent air leakage. See the detail drawing provided with
the unit for interface dimensions. These units are designed
to be ducted to a space to be conditioned and are intended
to condition only one room.
