Locating The Unit - Daikin Enfinity VFC Installation And Maintenance Manual

1 .
Locate the unit in an area that allows for easy
removal of the filter and access panels, and has
enough space for service personnel to perform
maintenance or repair. Provide sufficient room to
make water, electrical and duct connections.
2 . Make sure that sufficient access has been provided for
installing the unit, including clearance for duct collars
and fittings at water and electrical connections.
3 . Allow adequate room around the unit for a
condensate piping.
4 . The unit can be installed "free standing" in an
equipment room. However, closet installations are
more common for small vertical type units.
Generally, the unit is located in the corner of a closet
with the non-ducted return air facing 90° to the door and
the major access panels facing the door as in Figure 1.
Alternatively, the unit can have a ducted return air with
the opening facing the door and the major access panels
facing 90° to the door as in Figure 2.
5 . Unit must be located on top of a vibration absorbing
material such as a rubber (Isolation pad) that is
the same size as the base of the unit, to minimize
vibration and noise. See Figure 9 on page 10.
