EXECUTION
EXAMINATION
Do not begin installation until substrates have been properly prepared.
If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
Start of installation shall be considered acceptance of substrates.
PREPARATION
Clean surfaces thoroughly prior to installation.
Prepare surfaces using methods recommended by manufacturer for achieving best result for substrate under the project conditions.
Coordinate with window installation and placement of concealed blocking to support shades.
INSTALLATION
Install shades level, plumb, square, and true per manufacturer's instructions and approved shop drawings. Locate so shade band is at least 2 inches (51 mm) from interior face of glass. Allow proper clearances for window operation hardware. Use mounting devices as indicated.
Replace shades exceeding specified tolerances at no extra cost to Owner.
Adjust and balance roller shades to operate smoothly, easily, safely, and free from binding or malfunction throughout entire operational range. Adjust level, projection, and shade centering from mounting bracket. Verify there is no telescoping of shade fabric.
Clean roller shade surfaces after installation, per manufacturer's written instructions.
Demonstrate operation and maintenance of window shade system to Owner's personnel.
Manufacturer's authorized personnel are to train Owner's personnel on operation and maintenance of system.
Use operation and maintenance manual as a reference, supplemented with additional training materials as required.

Turn-Key Single-Source Responsibility for Motorized Interior Roller Shades: Design, engineering, and installation of motorized roller shade systems, motors, controls, and low voltage electrical control wiring specified is to be performed by a single manufacturer and their authorized installer/dealer.
The Architect will not provide a set of electrical drawings for installation of control wiring for motors, or motor controllers of motorized roller shades.
Power wiring (line voltage), to be provided by roller shade installer/dealer, per requirements provided by manufacturer. Coordinate following with roller shade installer/dealer:
Contractor To Provide the Following:
Power Panels and Circuits: Size to accommodate roller shade manufacturer's requirements, as indicated on mechanical and electrical drawings.

Line voltage as dedicated home runs, of sufficient quantity, and capacity as required. Terminate in junction boxes at locations designated by roller shade installer/dealer.
Run line voltage from terminating points to motor controllers. Wire roller shade motors to motor controllers. Run low voltage control wiring from motor controllers to switch/control locations designated by Architect.
Above-ceiling and concealed wiring to be plenum-rated, or in conduit, as required by the electrical code having jurisdiction.
Use conduit with pull wire in areas, not accessible to roller shade contractor due to building design, equipment location or schedule.
PROTECTION AND CLEANING
Protect installed products until completion of project.
Touch-up, repair or replace damaged products before Substantial Completion.
Clean soiled shades and exposed components as recommended by manufacturer.
Replace shades that cannot be cleaned to "like new" condition.
