Section 3 - Installation - IEC Vertical F*C Series Installation, Operation & Maintenance Manual

While the manufacturer is not involved in the design and
selection of support methods and components, it shall be
noted that unacceptable system operating characteristics
and/or performance may result from improper or
inadequate unit structural support. In addition, adequate
clearance must be provided for service and removal of the
equipment and its accessory components, consult local
codes. See Figure 2 for minimum recommendation for
clearances by manufacturer. Anchoring the equipment
in place is accomplished by using the mounting points
provided, and positioning the unit to maintain the drain pan
on a LEVEL plane. Care must be taken to insure that the unit
drain pan does not slope away from the outlet connection.
Vertical unit models FHC, FXC, FVC are designed to be floor
mounted or otherwise supported from below, and bolted
to the wall or floor structure through the mounting holes
provided in the chassis. These units may be wall hung only
when originally ordered from the factory for wall-mount
applications.
The type of mounting device is a matter of choice; however,
the mounting point shall always be that provided in the
chassis or cabinet. Refer to the unit product drawings for
hole mounting locations and sizes.
After mounting, the unit is then ready for the various service
connections such as water, drain and electrical. At this time,
verify that the proper types of service are actually provided
to the unit. On units requiring chilled water and/or hot
water, verify the proper line size and water temperature are
available to the unit.

Place Units In Position
F*C UNITS
1. Select the unit location. Allow adequate space for
free air circulation, service clearances, piping and
electrical connections, and any necessary ductwork.
For specific unit dimensions, refer to the submittal
drawing for your model. Allow clearances according to
local and national electric codes. See Figure 2 for basic
minimum clearance recommendations.

2. Make sure the floor is able to support the weight of
the unit. See Table 1 for nominal unit weight.
3. Ensure wall behind unit is smooth and plumb; if
necessary, install furring strips on walls with irregular
surfaces or mullions. Furring strips must be positioned
behind mounting holes in unit (FHC, FXC, FVC units).
Fasteners, furring strips, and other seals (if required)
must be field-supplied.
4. Remove all wall and floor moldings from behind the
unit.
5. Ensure FHC top panel (under window application)
and FXC, FVC front panel has been removed from unit
to obtain access to the four 0.75-in. mounting holes.
Fasteners and other required hardware must be field-
supplied.
6. Move unit into position. Ensure unit is level or slightly
pitched towards drain to ensure proper drainage and
operation.
