OUTLET 1/2 in. OD
Humidifier
CyberOne EC CW systems optionally include an electrode
steam humidifier. The humidifier empties into the
condensate drain line during the flush/drain cycle. A water
supply line must be connected to the 1/4 inch O.D. copper
tubing connection supplied by the factory. Refer to the
installation drawing supplied with the unit for the location
of the water supply connection. The humidifier requires
normal tap water for the water supply. If the supply water
is high in particulates an external filter may be needed.
NOTICE
Humidifier Damage!
Do not use de-mineralized water in the humidifier.
Refer to the humidifier operator's manual, supplied with
the equipment, for complete manufacturer's information
on the humidifier and the supply water recommendations.

WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state/national electrical codes.

Unit Damage!
INLET 7/8 in. OD
Improper wire connections could result in damage to
the unit.
Make sure the main power supply coincides with the
voltage, phase and frequency information specified on
the system nameplate. The supply voltage measured at
the unit MUST be within ±10% of the voltage specified
on the system nameplate.
The CyberOne EC CW uses three phase power in a range
of voltages. The operating voltage, frequency and phase
provided to the unit must match the specifications on the
unit nameplate (refer to
also provides the full load amps (FLA), the current the unit
will draw under full design load, the minimum circuit
ampacity (MCA) for wire sizing, and the maximum fuse or
HACR (Heating, Air Conditioning, Refrigeration) breaker
size (MAX FUSE/CKT BKR) for circuit protection. The unit's
nameplate is located inside the electrical box.
Note: If the nameplate states MAX FUSE/CKT BKR, fuses
or an HACR-type circuit breaker must be used to
protect the system. Other protection devices are
not allowed based upon the product listing.
The unit is provided with main power and control pilot
holes for connecting field-wiring conduits. These pilot
holes are located on the CyberOne EC CW unit based on
the configuration. On an upflow unit, the pilot holes are
located in the top of the cabinet. On a downflow unit, they
are located in the floor of the cabinet. A label stating
"MAIN POWER INPUT" is placed in close proximity. See
the installation drawing provided with the unit for pilot
hole locations. Terminate the main power wires at the line
side of the main power service disconnect switch located
in the electric box. A separate equipment ground lug is
provided in the electrical box for connecting an earth
ground wire.
The unit is equipped with terminals for all required field-
wiring. Refer to the electrical drawing supplied with the
unit for all power and control field-wiring. It is important to
identify the options that were purchased with the unit in
order to confirm which field connections are required.
