SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be

hazardous due to system pressure and electrical components. Only

trained and qualified personnel should install, repair, or service

air-conditioning equipment.

Untrained personnel can perform basic maintenance functions of

by trained service personnel. When working on air-conditioning

equipment, observe precautions in the literature, tags, and labels

attached to the unit, and other safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work gloves. Use

quenching cloth for unbrazing operations. Have fire extinguisher

available for all brazing operations. Consult a qualified installer or

service agency for information or assistance. The qualified in-

staller or agency must use only factory-authorized kits or acces-

sories when modifying this product.

WARNING: Before performing service or maintenance

operations on system, turn off power to unit. Turn off

accessory heater power switch, if applicable. Electrical

shock can cause personal injury.

Recognize safety information. This is the safety-alert symbol .

When you see this symbol in instructions or manuals, be alert to

the potential for personal injury.
