The humidifi er assembly shall include integral fi ll cup, fi ll
and drain valves and associated piping.
The canister shall be designed to collect the mineral
deposits in the water and provide clean particle free steam
to the air stream, thereby reducing maintenance cost.
The microprocessor control shall maintain humidifi er
operation through fi ll and drain cycles based on the water
conductivity. Overfl ow and loss of fl ow protection shall be
provided along with a manual drain switch. A high water
alarm with built-in time delay shall provide an indication
to change canister. The humidifi cation system shall require
no cleaning maintenance during the cylinder life.
The humidifi er shall discharge steam at 212 degrees F.
and atmospheric pressure. It shall be capable of operating
with water in the range of 200 to 1500 micromhos. The
steam shall be introduced into the air stream, after the
evaporator, by a calibrated discharge tube designed to
equally distribute the steam to the air stream without
condensation. The humidifi er shall have a capacity of 5
Lbs/hr.
A factory wired and installed humidifi er drain pump shall
be installed. This pump is designed to operate with the
higher condensate temperatures caused by the fl ush
and drain cycle of the electrode canister humidifi ers.
The humidifi er drain line will be connected to the main
condensate line prior to exiting the cabinet.
DEHUMIDIFICATION CYCLE
The CyberRow® unit shall be provided with a
dehumidifi cation control mode. During dehumidifi cation
demand, the control mode shall permit chilled water
valve operation and EC motor speed control to condense
moisture on the cooling coil.
ELECTRICAL SYSTEM
The electrical system shall conform to National Electrical
Code (NEC) requirements. In accordance with NEC Class II
circuits, the control circuit shall be 24 volts AC and control
circuit wiring shall not be smaller than 18 AWG. All wiring
shall be neatly wrapped, run in conduit or cable trays, and
routed in bundles. Each wire shall end with a service loop
and be securely fastened by an approved method. Each
wire in the unit shall be numbered for ease of service
tracing.
All electrically actuated components shall be easily
accessible from the front and rear of the unit without
reaching over exposed high voltage components or

Chilled Water
mounted in a stainless steel condensate drain pan. The
coil shall be designed for a maximum of 500 ft./min. face
velocity. The water circuit shall be designed to distribute
water into the entire coil face area.
PIPING CONFIGURATION
Top Piping:
When top piping is specifi ed, the CyberRow®
units shall be provided with connections for both the
chilled water piping and condensate discharge on the top
of the cabinet.
Bottom Piping:
When bottom piping is specifi ed (e.g.
raised fl oor applications), the CyberRow® units shall be
provided with connections for both chilled water piping
and condensate pump discharge on the bottom of the
cabinet.
CONDENSATE PUMP
The CyberRow® shall include a factory wired and installed
in-pan condensate pump. The condensate pump shall
have the capacity of 3 gal/hr. at 3 ft. of lift with a maximum
shut off (head) of 40 ft. The condensate pump shall be
piped with either top or bottom discharge connections to
remain consistent with top or bottom chilled water piping
connections.
2-WAY (STANDARD)
A 2-way modulating valve rated for a maximum 400 psig
w.w.p. shall be factory piped and wired. The 2-way chilled
water modulating valve shall automatically meter the
fl ow of chilled water to the cooling coil in response to a
proportional signal (0-10 VDC) provided to the valve by the
microprocessor controller w.w.p.
3-WAY (OPTIONAL)
The water circuit shall include a factory mounted, 3-way
modulating (0 - 10 VDC) control valve. Design pressure
shall be 400 psig.
STEAM GENERATING HUMIDIFIER
(OPTIONAL FOR 24” CABINET DESIGN)
The humidifi er shall be of a self-contained steam generating
electrode type, utilizing a plastic disposable cylinder with
full probes, connected to electric power via cylinder plugs
that slide onto the electrode pins. The electrode pins shall
be constructed from expanded low carbon steel, zinc
plated, and dynamically formed for precise current control.
