HOUSING INSTALLATION

Lectric IIe (Self-supporting fabric) and Lectric IVe (Tab-tensioned fabric) are

designed for flush ceiling mount. These units are suitable for use in environmental air space in accordance with

Section 300-22 (C) of the National Electric Code, ANSI/NFPA 70, and Sections 2-128, 12-010(3) and 12-100 of

the Canadian Electric Code, Part 1, CSAC22.1. As shown in Figure 2a, Opti on 1 is the preferred m ounting

method which requires access space above the ceiling. The m ounting brackets m ay be placed any where along

the housing length as desired. However, it is best to even ly space them for uniform weight distribution. It is

recommended the end m ounting brackets should not be m ore 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

to provide 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 th

e housing is level and plum b. Make adjustm ents 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).

Option 1 - Suspended Mounting

An alternate m ounting method is available as shown in Figure 3. This m ounting option m ust 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 clearance for the m ounting screws

along the middle section of the housing.
