HOUSING INSTALLATION
Lectric 2-C is designed for flush ceiling mount. As shown in Figure 2a, Option 1 is the preferred mounting
method which requires access space above the ceiling. The mounting brackets may be placed anywhere along
the housing length as desired. However, it is best to evenly space them for uniform weight distribution. It is
recommended the end mounting brackets should not be more than 4 inches from each end of housing.
The housing has a built-in trim flange around the bottom. Ceiling tiles or drywall may be placed on top of this
flange for a finished appearance.
WARNING:SUPPORTINGSTRUCTUREMUSTBECAPABLEOFCARRYING4TIMESTHEUNITWEIGHT.CHECKWEIGHTDATAATTHEENDOF
THISDOCUMENT.
Threaded rods of 3/8 (10mm) diameter, hex nuts and helical lock washers are to be provided by installers.
After securing the housing in the ceiling check that the housing is level and plumb. Make adjustments as
necessary then tighten the hex nuts.
It is recommended that safety cables be added to the housing for additional safety concern. The cables may be
looped and tied to end mounting brackets between the housing and bracket (Figure 2c).
An alternate mounting method is available as shown in Figure 3. This mounting option must be requested in
advance at the time of order placement for the mounting holes to be drilled.
It is the installer responsibility to supply proper mounting hardware for option 2 mounting.
Option 2 mounting requires the screen roller assembly to be removed to gain access for the mounting screws
along the middle section of the housing.
