NOTICE

It is very important to read the installation instructions thoroughly before beginning 

the project. Make sure you have drawings and instructions for the equipment being 

installed. If not, call the manufacturer to receive the proper instructions and draw-

ings. Every manufacturer of electronic equipment should have a knowledgeable staff, 

willing to answer your questions or provide additional information. Following correct 

wiring procedures will ensure proper installation and consequently, proper operation 

of your electronic equipment.
