Ship-Loose Accessories-Field-Installed; Remote Monitoring, Autochangeover, And Leak Detection Equipment - Vertiv Liebert Mini-Mate2 MMD24E Technical Data Manual

4 SHIP-LOOSE ACCESSORIES—FIELD-INSTALLED
A High Static Blower Assembly can be field-attached to the evaporator to provide up to 2.0" (51mm) of
external static pressure on the discharge side of the evaporator. The blower box contains a centrifugal-
type double-inlet blower. This blower is equipped with a belt drive and 1.5 hp single speed motor mounted
to an adjustable motor base. Note: Unit must be ordered without the internal direct drive motor and the
high static blower disables the two-speed fan operation feature.
Filter box kit (for ducted applications) includes filter box with duct flange connection, one MERV 8
(ASHRAE 52.2-2007) filter (20"x20"x4" [508mm x 508mm x 102mm]), and a duct flange for use on the
supply air opening of the unit.
Air Distribution Plenum includes molded plastic three-way discharge plenum, 16"x25"x4" (406mm x
535mm x 102mm) MERV 8 filter (ASHRAE 52.2-2007), and sheet metal block-off plates for covering the
duct openings on the evaporator unit. Plenum mounting requires T-bar ceiling grid.
The Condensate Pump is field-mounted external to the cabinet, wired to the unit power block and is
equipped with a check valve. A secondary float can be field-wired to shut down the unit upon high
condensate level.
A Remote Temperature and Humidity Sensor package includes sensors in an attractive case with 30 ft. (9
m) 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.
NOTE: Installing the remote sensors disables the sensors included in the wall box.
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.
277-to-208V step-down transformer (37.5 amps) allows use of 277-1-60 supply power with a 208-1-60
Prop Fan Condensing unit. The transformer is coated with epoxy and contained in an enclosed, non-
ventilated electrical box with adaptable mounting brackets.
Single-Point Power Kit contains the necessary electrical components to interconnect the high-voltage
sections of a close-coupled evaporator and an MCD condensing unit.
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.
The 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.

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.
