Filter Box includes filter box with 1" (25.4mm) duct flange connection, quantity 2, 20" x 20" x 4"
nominal (508mm x 508mm x 102mm) filters and a 1" (25.4 mm) duct flange for use on the supply air
opening. Filters are MERV 8 efficiency per ASHRAE Standard 52.2-2007.
Condensate Pump is equipped with a discharge check valve. The pump is supplied with a mounting
bracket for field-mounting onto ductwork and can be field-wired to the unit power block. A secondary
float can be field-wired to shut down the unit upon high condensate level.
Condensate Pump Mounting Bracket is available for a mounting condensate pump on the end of
the unit instead of on the duct work for easy alignment and installation of the condensate pump.
Remote Temperature and Humidity Sensors include sensors mounted in an attractive case with
30 ft. (9m) of cable. Installing the remote temperature and humidity sensor module disable the
temperature and humidity sensors mounted in the wall box.
Field-installed kits are available for filter clog, smoke sensor, high temperature sensor, electric
reheat and humidifier. The kits include installation instructions and are designed to be added to the
evaporator unit before it is installed in the ceiling. Electric reheat kits cannot be installed in units
with free-cooling.
Refrigerant-line sweat adapter kit contains two suction and two liquid-line compatible fittings
that allow use of field-supplied, interconnecting refrigerant lines.
Single Point Power Kit contains the necessary electrical components to interconnect the high
voltage sections of a close-coupled evaporator and indoor condensing unit.

Remote Monitoring, Autochangeover and Leak Detection Equipment
The Liebert RCM4™ is a four-point, normally open, dry contact monitoring panel. One Form-C, dry
contact common alarm relay output (rated at 24VAC, 3A) is provided. Four red LEDs illuminate on
the respective alarm and the alarm buzzer is silenced by a front panel switch. The RCM4 requires a
24VAC or 24VDC power source. Power supply is not included.
The Liebert AC4™ Autochangeover Controller provides autochangeover and autosequence
control for up to four Liebert Mini-Mate2 units within a room. The Liebert AC4 will enable redundant
units in an alarm condition, balance usage and test standby units at programmed intervals. Two
common alarm relay outputs are available. A built-in LCD and RS-232 port for direct PC/terminal
connection provides two options for configuration and monitoring of the product. The Liebert AC4
requires 24VAC input power.
The Liebert AC8™ is ideal for coordinated control of systems with redundant units. The Liebert AC8
enables redundant devices during an alarm condition, balances usage of devices and tests standby
devices at programmable intervals. Supports four zones and can use the 4-20mA temperature sensor
(TW420) for temperature staging in each zone. Two programmable output control relays are available
for auxiliary control such as humidity lockout. Emergency power operation input provided for device
control during an emergency. Two common alarm relay outputs are available. A built-in LCD and
RS-232 port for direct PC/terminal connection provides two options for configuration and monitoring
of the product.
The Liebert ENV-DO™ interface card provides 16 discrete outputs, corresponding to status and
major alarm conditions of Environmental units. The Liebert ENV-DO-ENCL1 packages one
Environmental DO interface card in its own steel enclosure and the ENV-DO-ENCL2 packages two
Environmental DO interface cards in one enclosure for installation external to the Liebert
Mini-Mate2. The self-contained kit includes an external 120VAC-to-24VAC power transformer.
Wiring harnesses are not provided. Power and communication wiring is field-provided.
The Liebert Liqui-tect® 410 Point Leak Detection Sensor detects the presence of conductive
liquid using a pair of corrosion-resistant, gold-plated probes mounted in a painted, height-adjustable
enclosure. Dual Form-C, dry contact common alarm relays (rated at 24VAC, 3A) signal a leak
detected as well as loss of power and cable fault. The Liebert Liqui-tect 410 requires an external
24VAC or 24VDC power source.
Liebert LT460 Zone Leak Detection Kits include one LT460 sensor, a specified length of
LT500-xxY cable (maximum length is 100 ft [30.5m]) and a corresponding number of hold-down clips.
The Liebert LT460 requires an external 24VAC, 0.12A power source, such as EXT-XFMR or XFMR24.
