3.0 OPTIONAL FACTORY-INSTALLED FEATURES - EVAPORATOR/CHILLED WATER UNITS
3.1 Reheat
Electric Reheat includes 304/304 stainless steel finned tubular reheat elements, with high limit
safety switch.
SCR Electric Reheat uses an SCR controller and unit control software to provide full cooling with
modulating of the electric reheat elements to control air temperatures. Reheat capacity is up-sized to
offset the cooling capacity. (The SCR Electric Reheat is not available on chilled water, free-cooling or
575V units.)
Hot Water Reheat includes hot water coil, two-way solenoid valve and Y-strainer.
3.2 Humidifier
The Canister Humidifier includes a steam-generating type humidifier with automatic flushing
circuit, inlet strainer, drain, 1" (25.4mm) air gap on fill line and solenoid valves. Humidifier problem
alarm annunciates at the wall-mounted display panel.
Remote Humidifier Contact allows the unit’s humidity controller to control a humidifier outside
the unit. Power to operate the remote humidifier does not come from the Liebert Mini-Mate2.
Available on units with or without internal humidifier.
3.3 Sensors
Smoke Sensor checks return air, shuts down the unit upon sensing smoke and activates visual and
audible alarms at the wall-box display. This smoke sensor is not intended to function as or replace
any smoke sensor system that may be required by local or national codes.
High-Temperature Sensor senses the return air temperature and shuts down unit if the
temperature reaches 125°F (52°C). This device is not meant to replace any fire detection system that
may be required by local or national codes.
3.4 Switches and Motors
Filter Clog senses pressure drop across the filters and activates visual and audible alarms at the
wall-box display. The wall-box display annunciates the alarm audibly and flashes a notification upon
reaching a customer setpoint.
A Factory-Installed Non-Fused Disconnect Switch allows unit to be turned off for maintenance.
A disconnect switch is standard for the evaporators, chilled water units and indoor condensing units,
but these units may be specified without the switch.
2hp Blower Motor is available for high static applications (0.9 to 1.5 in. [23 to 38 mm] w.g.).
NOTE
This option is available only on chilled water units, but not with other reheat options.
