Supply and Return Grille Kit includes supply and return grilles, 1" x 20" x 20"
(25mm x 508mm x 508mm) MERV 8 rated filter to ASHRAE 52.2-2007, for installation into a
2ft. x 4ft. (610mm x 1220mm) ceiling grid.
Duct Kit includes return air filter box with 1" duct collar, 1" duct collar for supply air, and air
block-off plates. Duct kit is supplied with a 4" x 16" x 20" (102mm x 406mm x 508mm) MERV 8 filter
(based on ASHRAE 52.2-2007)
Duct Collar Kit (no filter) includes 1" supply duct collar, a 1" return collar, and the necessary
block-off plates to make the Liebert Mini-Mate2 a ducted configuration. Filter box and filter are not
included.
Condensate Pump is field-mounted on the outside of the cabinet, wired to the unit power block and
is equipped with a discharge check valve. A secondary float is field-wired to shut down the unit upon
high condensate level. Power can be obtained from the Liebert Mini-Mate2 electrical panel.
Pre-Charged Refrigerant Line Set (R-407C) contains an insulated copper suction line and a
copper liquid line for interconnection of the indoor and outdoor sections. Available in 15-foot (4.5m)
and 30-foot (9m) sections.
Refrigerant-Line Sweat Adapter Kit contains two suction and two liquid line fittings that allow
field-supplied refrigerant piping between the evaporator and condensing unit.
A
Remote Temperature and Humidity Sensor package includes sensors in an attractive case
with 30 ft. (9m) of cable. Can be wall- or duct-mounted. Remote sensors should be used when the wall
box is not located in the space to be conditioned.
Field-Installed Kits 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.
4.1 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 24 VAC, 3 Amp) 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.
NOTE
Installing the remote sensors disables the sensors included in the wall box.
