GENERAL INFORMATION CONT·

CLEANING MATERIALS:

Cement, plaster, terrazzo, alkaline and acid based materials used to clean masonry are very harmful to

finishes and should be removed

ith

water and a mild soap immediately or permanent staining

will occure. A spot test is recommended before any cleaning agent is used.

EXPANSION JOINTS:

Expansion joints and perimeter seals shown in these instructions and in the shop draw ings are show n at

normal size. Actual dimensions may vary due to perimeter conditions and/or differences in metal tempera-

ture between the time of fabrication and time of installation. For example, a 12 foot unrestrained length of

aluminum extrusion can expand or contract 3/32 of an inch over a 50 degree Fahrenheit change. Any

movement potential should be accounted for at time of the installation.

THERMAL IMPROVEMENT SUGGESTIONS:

To maintain or improve your wall installation, the following items should be considered:

1. Blinds or drapes prevent warm air from washing the window.

2. Warm air ventilators too far from window will not adequately wash the window with air to

prevent condensation.

3. In extreme conditions, the fan of the heating systems should not cycle on and off, but run

continuously.

4. Some heating systems have a water injection feature that can raise humidity levels. The

higher the humidity levels the more likely condensation or frost will form. Raising the

temperature and reducing humidity will usually solve this problem.

5. On rare occasions, an extremely cold storm may cause frost to appear on the glass or

framing. A space heater and electric fan blowing along the plane of the window wall can

reduce or eliminate this temporary condition.

FABRICATION SUGGESTIONS:

The use of our EZ Punch tool is reccommended for faster and more accurate fabrication of wall

systems. If hand fabricating the mullions; drill fixtures are available to improve accuracy. Fabrication

instructions for use of these drill fixtures are described within this manual on pages 37 through 41.
