INI-SPACE EC INSTALLATION, OPERATION AND MAINTENANCE MANUAL
A water supply line for the humidifi er must be connected to
the end of the copper tubing provided by the factory. Refer
to the installation drawing provided with your unit for the size
and location of the connection. The humidifi er requires normal
tap water for 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 information on the
humidifi er and the supply water recommendations.
2.8 Utility Connections
2.8.1 Main Power
The Mini-Space EC is available in single or three phase power
in a wide range of voltages. The unit nameplate (see Figure 8)
lists the operating voltage, frequency and phase of your unit
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 protection. The unit’s
nameplate is located inside the cabinet within the electric box.
NOTE
If the nameplate states MAX FUSE/CKT BKR, it
is required to use fuses or an HACR-type circuit
breaker to protect the system. Other protection
devices are not allowed based upon the product
listing.
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 connections are required.
WARNING
Verify power is turned off before making connections
to the equipment.
NOTE
All wiring must conform to local and national
electrical codes. Only use copper conductors. Wiring
terminations may become loose during transit of
the equipment; therefore, it is required to verify
that all wiring terminations are secure prior to initial
operation.
