    FILE NO. SVM-14017 1. SAFETY PRECAUTIONS Installing, staring up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.). Only trained, qualified installers and service mechanics should install, start-up, and service this equipment. Untrained personnel can perform basic maintenance functions such as cleaning coils.
  • Page 4 FILE NO. SVM-14017 DANGER FOR USE BY QUALIFIED PERSONS ONLY. • • TURN OFF MAIN POWER SUPPLY BEFORE.ATTEMPTING ANY ELECTRICAL WORK. MAKE SURE ALL POWER SWITCHES ARE OFF. FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK. • CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED WRONGLY, ELECTRIC PARTS MAY BE DAMAGED.
  • Page 5 FILE NO. SVM-14017 CAUTION CAUTION • Exposure of unit to water or other moisture before installation could result in electric shock. Do not store it in a wet basement or expose to rain or water. • After unpacking the unit, examine it carefully for possible damage. Report any damages to your distributor. Do not install in a place that can increase the vibration of the unit.
