CyberOne EC DX IOM Manual
Always refer to the manufacturer’s SDS provided
with the unit.
CAUTIONS
Certain maintenance or cleaning procedures may
call for the use and handling of chemicals, solvents,
or cleansers. Always refer to the manufacturer’s
material Safety Data Sheet (SDS) prior to using
these materials. Clean parts in a well-ventilated
area. Avoid inhalation of solvent fumes and
prolonged exposure of skin to cleaning solvents.
Wash exposed skin thoroughly after contact with
solvents.
Do not use cleaning solvents near open flame or
excessive heat. Wear eye protection when blowing
solvent from parts. The pressure-wash should
not exceed 30 psig. Solvent solutions should be
disposed of in accordance with local and state
regulatory statutes.
WARNING
When performing brazing or debrazing operations,
make certain the refrigeration system is fully
recovered and purged and dry nitrogen is flowing
through the system at the rate of not less than 1-2
CFM (0.03-0.06 m³/minute).
CAUTIONS
Cooling coils (and associated piping circuits)
are pressurized (up to 100 psi) and sealed
when they leave the factory. Before installing
the interconnecting piping, observe appropriate
safety precautions and release the pressure via
an available stem valve or Schrader valve prior to
uncapping the pipes.
After interconnecting piping is installed, the piping
system must be cleaned. If solvents/cleaning
solutions are used, ensure they are completely
flushed from the piping before connecting it to
the unit. Failure to do so may result in equipment
problems.
CAUTION
When installing and filling the chilled water or
water/glycol loop, all air must be bled from the
piping system.
WARNING
Do not use chloride based water conditioning
additives in condensate drain pans. This will cause
corrosion to occur on the coil fins.

General Design
The CyberOne EC DX system is housed in a steel frame
type cabinet and is rated for indoor use. The exterior of the
cabinet is coated with a powder coat finish to protect
against corrosion. A hinged door is located in the front of the
cabinet for easy access to all components. Operator controls
are conveniently located on the front of the cabinet.
NOTE
Customer specified nonstandard features or
design variations may not be described in this
manual. Refer to the installation and/or electrical
drawings supplied with your unit for details on
additional feature(s). In some cases, an addendum
to this manual may also be included to further
describe the feature(s).

EC downflow unit and identifies the major components. The
location of major components vary depending on the model
number and options purchased.

number and options purchased.
1.4.1
Electrical Compartment
The electrical components are protected behind the front
hinged access door. The location of the electrical components
varies depending on the control options provided with your
unit.
The access door is safety interlocked with the main power
service disconnect switch (See Figure 1 and Figure 2)
preventing the door from opening when the switch in the On
position. The switch must be turned Off to gain access to the
electrical compartment.
The service disconnect switch may be used to turn the unit
off for emergency shutdown or when routine maintenance
is performed. The handle of the switch may be locked in the
Off position to prevent unintended operation.
