INSTALLATION
Complete Pre-installation Checks

stallation. When unpacking indoor unit, be careful not to
lift unit by condensate drain discharge pipe or by refrigerant
connections.

indoor and outdoor units for damage. If there is any dam-
age, forward claim papers directly to the transportation
company. Manufacturer is not responsible for damage in-
curred in transit.

against parts list (see page 4). If any items are missing, noti-
fy your distributor or Carrier office.
To prevent loss or damage, leave all parts in original packages until
