 WARNING: Before performing service or maintenance operations on a system,

turn off main power switches to the indoor unit. If applicable, turn off the accessory heater

power switch. Electrical shock could cause personal injury.

Installing and servicing heating and air conditioning equipment can be hazardous due to

system pressure and electrical components. Only trained and qualified service personnel should

install, repair or service heating and air conditioning equipment.

Untrained personnel can perform the basic maintenance functions of cleaning coils and

cleaning and replacing filters. All other operations should be performed by trained service

personnel. When working on heating and 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 a quenching cloth for

brazing operations and have a fire extinguisher available.

Move units in the normal “up” orientation as indicated by the arrows on each carton. Horizon-

tal units may be moved and stored per the information on the carton. Do not stack more than

three units in total height. Vertical units may be stored one upon another to a maximum height of

two units. Do not attempt to move units while stacked. When the equipment is received, all items

should be carefully checked against the bill of lading to be sure all crates and cartons have been

received. Examine units for shipping damage, removing the units from the cartons if necessary.

Units in question should also be internally inspected. If any damage is noted, the carrier should

make the proper notation on the delivery receipt, acknowledging the damage.
