When unpacking indoor unit, be careful not to lift unit by con-
densate drain discharge pipe or by refrigerant connections.
2. Inspect Shipment - - Upon receipt of shipment, check the in-
door and outdoor units for damage. If there is any damage,
forward claim papers directly to the transportation company.

3. Inspect Parts Supplied With Units – Check all items
against parts list (see the PARTS LIST section). If any items
are missing, notify your distributor or manufacturer office.
To prevent loss or damage, leave all parts in original pack-
ages until installation.
Consider System Requirements
1. Consult local building codes and NEC for special installa-
tion requirements.
2. When deciding the location of the indoor and outdoor units,
ensure that the piping run does not exceed the allowed dis-
tances listed in Table 9.
3. Make sure the indoor and outdoor units are easily accessible
to electrical power.
4. Allow sufficient clearances for airflow, wiring, refrigerant
piping, and servicing the unit (see the "CLEARANCES - -
INDOOR" and "CLEARANCES - - OUTDOOR" sections).
