the data center. 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 chart is the minimum recommended 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 still maintaining the
requirement of the Indoor Air Quality (IAQ) standard.
Lack of attention to these factors can cause erratic
operation, unstable room control and excessive
maintenance costs.

Rigging
STULZ CyberAir systems are designed to be kept
in a vertical position. Move the unit with a suitable
device such as a forklift, pallet jack, or roller bar
and dollies. A weight table is provided on the
installation drawing.
The unit is shipped on a skid to facilitate moving
prior to installation. The unit should always be
stored indoors in a dry location prior to installation.
CAUTION
When moving the unit, it must be kept level
and in the vertical position when lifting to
prevent damage.
2.4
Mounting/Placement
STULZ CyberAir systems use a frame and panel
construction for unit rigidity. The cabinet design
allows full service accessibility without moving the
unit. STULZ CyberAir systems that are not ducted
are designed to be located in the space to be
conditioned. Ducted units may be located inside or
outside the conditioned space but are designed to
supply air to only one room. STULZ CyberAir
systems are front accessible, which allows the
unit to be placed in a corner or between cabinetry.
It is recommended that the unit is positioned to
obtain optimum air circulation.
NOTE
Placement of the floor or ceiling registers
is important. If they are too close to the unit,
the supply air will be recirculated back to
the unit before it has circulated throughout
the space.
See Figures 8 & 9. The STULZ CyberAir unit is
designed to be located directly on top of the floor
(typically upflow) or on a raised floor (typically
downflow).
Figure 8- Typical CFU (Upflow)
Installation NOTE
The equipment must be level to operate
properly.
CAUTION
Ensure the mounting surface is capable of
supporting the equipment. Before mounting
the unit, refer to the weight table provided on
the installation drawing. On some raised floor
installations a floor stand may be required
(see Figure 9) depending on the load capacity
of the existing raised floor.
