4.4 Equipment Inspection
Concealed Damage
Inspect all cartons and packages upon receipt for damage in transit. Remove cartons and check for
concealed damage. Important: Keep the unit upright at all times. Remove access panels and examine
component parts. ( Note: The top ( optional ) and bottom brackets are stored in the condenser air compart-
ment. Remove them before replacing the side screen ). Inspect refrigerant circuit for fractures or breaks.
The presence of refrigerant oil usually indicates a rupture. If damage is apparent, immediately file a claim
with the freight carrier.
Units that have been turned on their sides or tops may have concealed damage to compressor motor
mounts, to the oil system or to other components. If the unit is not upright, immediately file a claim for
concealed damages and follow these steps:
1. Set unit upright and allow to stand for 24 hours with primary power turned on.
2. Attempt to start the compressor after 24 hours.
3. If the compressor will not start, makes excessive noise, or will not operate, return the unit to the
freight carrier.
General

information in section 5.6, Installation Kits.
