SECTION II – Product Line Specific Installation
Part 1 – Universal Hi-Rise Units (MUY)
The unique design of the Universal Modular Fan Coil unit
allows for field configuration for each unit. Air discharge,
riser, drain, and outside air knockouts have been strategically
located on each unit. Risers, shown with unit, are for
reference only. All risers are factory fabricated and shipped
loose for field installation.
It is important that you identify all of the unit feature
locations and which knockouts you intend to use before
proceeding with the installation. Also, it must be determined
whether your application requires a Mating Unit (primary/
secondary) and its configuration. Consult your local sales
representative or the factory for further details on primary/
secondary arrangements.
Potential Unit Configurations
Risers:
Three Locations–The pre-installed Supply, Return, and
Drain risers (2-pipe or 4-pipe applications) can be oriented on
any of three sides of the unit (see Figure 1).
NOTE:
Risers can not be installed on the Return Air side of the
cabinet.

Figure 1
Unit orientation is determined based on the location of the
risers in the building. The riser side of the Universal Modular
unit always determines the rear of the unit (see Figure 2).
Return Air:
Single Location–The Return Air/Access panel
may then be oriented on the left, right, or front of the unit.
Supply Air:
Five Locations (4 sides and top) includes
stitched design for 1/2” duct flanges.
Outside Air:
Two Locations–Either side adjacent to the
Return Air opening.
NOTE:
Outside Air opening may not be used on a side if risers are
configured on that same side.
