STANDARD FEATURES/ALL SYSTEMS
2.1.1 Evaporator Cabinet Construction
The cabinet and chassis shall be constructed of heavy gauge galvanized steel, and shall be serviceable
from one side. Mounting brackets shall be integral to the cabinet design. Internal cabinet insulation shall
meet ASHRAE 62.1 requirements for Mold Growth, Humidity & Erosion, tested per UL 181 and
ASTM 1338 standards.
2.1.2 Air Distribution
The air distribution system shall be constructed with a quiet, direct-drive fan assembly equipped with
double-inlet blower, self-aligning ball bearings and lifetime lubrication. Fan motor shall be permanent-
split capacitor, high-efficiency type, equipped with two speeds for airflow modulation. The
microprocessor controller shall use the lower fan speed for precise dehumidification control. Fan speed
shall also be user selectable from the wall controller.
Each system shall be capable of delivering ____CFM (____ CMH) at high fan speed. The fan motor shall
be ____ HP (____ W).
System shall be suitable for supply and return air plenum or ducted supply and return air distribution.
Refer to 2.5.2 - Air Filter Box, 2.5.3 - Air Distribution Plenum and 2.5.4 - High Static Blower Assembly.
2.1.3 Microprocessor Control
The control system shall be microprocessor-based, factory-wired into the system and tested prior to
shipment. The wall-mounted controller shall include a 2-line by 16-character character liquid crystal
display (LCD) providing continuous display of operating status and alarm condition and shall be capable
of displaying values in °F or °C. An 8-key membrane keypad for setpoint/ program control, fan speed
selection and unit On/Off shall be located below the display. Controller shall be password protected to
prevent unauthorized set point adjustments. Field-supplied 4-conductor thermostat wire shall be used to
connect the wall-mounted controller to the unit control board.
Temperature and humidity sensors shall be located in the wall controller, which shall be capable of being
located up to 300 ft (91.4m) from the evaporator unit when using a remote temperature/humidity sensor
in the conditioned space.
2.1.3.1 Monitoring
The LCD shall provide On/Off indication, operating mode indication (cooling, heating, humidifying,
dehumidifying), fan speed indication and current day, time, temperature and humidity (if applicable)
indication. The monitoring system shall be capable of relaying unit operating parameters and alarms to
the Liebert iCOM-CMS or Liebert
®
SiteScan monitoring systems.
