from improper installation, operation or maintenance is
not covered by the warranty.
STUDY the instructions contained in this manual.
They must be followed to avoid difficulties. Spare parts
are available from SATS to insure continuous opera-
tion. Using substitute parts or bypassing electrical or
cooling components in order to continue operation is
not recommended and will VOID THE WARRANTY.
Due to technological advancements, components are
subject to change without notice.
All
Compact CW systems are designed to be installed
indoors, unless otherwise noted on the equipment.

Product Description
Compact CW systems are designed to be the most
versatile and flexible floor mounted precision air
conditioning systems in the industry. The unit is
available in up-flow or down-flow configurations. The
cooling capacity, in kW, will depend on the unit size,
which can range from 30 to 180 kW, (1 kW = 3415
BTU/Hr). Refer to the unit nameplate to identify the
model number and cooling capacity of your unit.
Compact CW systems operate with an external
source of chilled water. The chilled water system is a
closed loop circuit in which cold water is circulated
through a chilled water coil. On demand for cooling,
the microprocessor controller begins modulating the
chilled water valve open. Chilled water flows to the coil
at a rate that varies proportionally to the amount of
cooling required to meet the user selectable tempera-
ture setpoint. Heat from the surrounding air is trans-
ferred through the finned tubing of the coil into the cold
water. Water is then re-circulated back to the cold
water source.
Compact CW systems have been designed to supply
air to only one room.
NOTE
Compact CW systems are strictly for non-resi-
dential applications.
The functional modes of operation, in addition to
cooling, are heating, humidification and dehumidifica-
tion, which provide complete environmental control of a
conditioned space.
There are two air pattern configurations, upflow and
downflow, and several cabinet sizes based on the type
of system and capacity. Regardless of configuration,
the
Compact CW system is compact and versatile.
See the Installation drawing provided with the unit for
the layout and dimensions of the cabinet.
The
Compact CW unit is provided with a factory
mounted, main power disconnect switch with a lockable
handle. The disconnect switch electrically isolates the
unit during routine maintenance. The system incorpo-
rates state of the art component protection with the use
of motor start protectors and circuit breakers.
An operating manual for the system controller is
provided under separate cover. Refer to that manual for
detailed instructions on operating the system control-
ler provided with your unit.
The standard controller for
Compact CW precision A/C
units sizes CCD/U-300 through CCD/U-900 is SATS
model C1002. For larger units, CCD/U-1500 through
CCD/U-1800, the standard controller is the SATS
model C6000. These microprocessor controllers
provide the following features: input/output monitoring
status, full integrated control of heating, cooling,
humidification and dehumidification; multi-unit control
and remote communication with building management
systems. The controller is typically factory mounted
on the front hinged access door of the unit. As an
option the controller may be remotely mounted to a
wall or control panel.
SATS offers the C6000 microprocessor controller as
an option for models CCD/U-300 through CCD/U-900
A/C units.
