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.
