Drain water must be directed to an appropriate place
such as an open building drain. Include an air gap per
local and national plumbing codes.
The humidifi er requires normal tap water as the water
supply. If the supply water is high in particulate, an
external fi lter may be needed.
CAUTION
Do not use demineralized water.
Refer to the humidifi er operator’s manual, supplied
with the equipment, for complete manufacturer’s infor-
mation on the humidifi er and for supply water recom-
mendations.
2.8 Utility Connections
2.8.1 Main Power
The CyberRow product offering is available in single or
three phase variations and a wide range of voltages.
It is imperative that the unit nameplate be examined
to determine the operating voltage, frequency and
phase of the system (see Figure 6). The nameplate 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 protec-
tion. The unit’s nameplate is located inside the cabinet
within the electrical box.
NOTE
If the nameplate states MAX FUSE/CKT BKR, it
is required to use fuses or a HACR type circuit
breaker to protect the system. Other protection
devices are not allowed based upon the product
listing.
Figure 6- Sample Nameplate
The unit is provided with terminals for all required
fi eld-wiring. Refer to the electrical drawing supplied
with the unit for all power and control fi eld-wiring. It is
important to identify the options that were purchased
with the unit in order to confi rm which fi eld connec-
tions are required.
NOTE
All wiring must conform to local and national
electrical code requirements. Use of copper con-
ductors only is required. Wiring terminations may
become loose during transit of the equipment;
therefore, it is required to verify that all wiring
terminations are secure.
