3.0OPTIONAL FACTORY-INSTALLED FEATURES - EVAPORATOR/CHILLED WATER UNITS
3.1Reheat
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.
NOTE
This option is available only on chilled water units, but not with other reheat options.
3.2Humidifier
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.
3.3Sensors
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.
3.4Switches 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-InstalledNon-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.).
