operation. The humidifier requires a 1/4 inch water
supply line, connected to the compression fitting on
the side of the humidifier chassis. The humidifier
empties directly into the condensate pan for the flush/
drain cycle.

Main Power
The
Compact CWE
product offering is available in 208,
460 and 575 volt three-phase configurations. 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 that the
unit will draw under full design load, the minimum
circuit ampacity (MCA) for wire sizing, and the maxi-
mum fuse or HACR (Heating, Air Conditioning, Refrig-
eration) breaker size (MAX FUSE/CKT BKR) for circuit
protection. 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 utilize fuses or HACR type cir-
cuit breakers to protect the system. Other pro-
tection devices are not allowed based upon the
product listing.
The unit is provided with terminals for all required field-
wiring connections. Refer to the electrical schematic
supplied with the unit for all power and control field-
wiring connections. It is important to identify the
options that were purchased with the unit in order to
confirm which field connections are required.
WARNING
Verify power is turned off before making connec-
tions to the equipment.
NOTE
All wiring must conform to local and national elec-
trical code requirements. Use of copper conduc-
tors 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.
