Vertiv Liebert Mini-Mate MT048 - PRE-INSTALLATION PREPARATION AND GUIDELINES; Planning Dimensions; Location Considerations

3 PRE-INSTALLATION PREPARATIONANDGUIDELINES
NOTE: Before installing unit, determine whether any building alterations are required to run piping,
wiring and ductwork. Follow all unit dimensional drawings and refer to the submittal engineering
dimensional drawings of individual units for proper clearances.
Refer to Model-number Digit Definitions on page9, and submittal drawings to determine the type of
system being installed and anticipate building alterations, piping and ductwork needed.
The unit dimensions, pipe-connection locations, and piping schematics are described in the submittal
documents included in the Submittal Drawings on page53.
• Confirm that the room is properly insulated and has a sealed vapor barrier.
• For proper humidity control, keep outside or fresh air to an absolute minimum (less than 5% of
total air circulated in the room).
• Install the units as close as possible to the largest heat load.
• Allow at least the minimum recommended clearances for maintenance and service. See the
appropriate submittal drawings for dimensions.
• We recommend installing a water detection system. Contact your Vertiv representative for
information.

3.2 Location Considerations
The evaporator is usually mounted above the dropped ceiling and must be securely mounted to the roof
structure. For ducted systems, the evaporator may be located in a different room. See Guidelines for
Ducted Systems on page29, for additional guidelines. For a split system with an air-cooled, outdoor
condensing unit, the condensing unit may be mounted on the roof or remotely in an outdoor area. See
Location Considerations for Outdoor Condensing Unit on the next page, for additional guidelines.
Refer to Refrigerant-line Sizes and Equivalent Lengths on page17 for maximum refrigerant line lengths.
The ceiling and ceiling supports of existing buildings may require reinforcement. See Mini-Mate Unit
Weights on page13. Be sure to follow all applicable national and local codes.
Install the ceiling-mounted unit over an unobstructed floor space if possible. This will allow easy access for
routine maintenance or service. Do not attach additional devices (such as smoke detectors, etc.) to the
housing, as they could interfere with the maintenance or service.
Do not install units in areas where normal unit operating sound may disturb the working environment.
