Transportation & Storage
Installation
General
Upon receipt of the equipment, check carton for visible
damage . Make a notation on the shipper’s delivery ticket
before signing . If there is any evidence of rough handling,
immediately open the cartons to check for concealed dam-
age . If any damage is found, notify the carrier within 48
hours to establish your claim and request their inspection
and a report . The Warranty Claims Department should then
be contacted .
Do not stand or transport the machines on end . For stor-
ing, each carton is marked with “up” arrows .
In the event that elevator transfer makes up-ended posi-
tioning unavoidable, absolutely ensure that the machine is
in the normal upright position for at least 24 hours before
operating .
Temporary storage at the job site must be indoors,
completely sheltered from rain, snow, etc . High or low tem-
peratures naturally associated with weather patterns will
not harm the conditioners . Excessively high temperatures,
140°F (60°C) and higher, may deteriorate certain plastic
materials and cause permanent damage .
1 . To prevent damage, this equipment should not be oper-
ated for supplementary heating and cooling during the
construction period .
-2 . Inspect the carton for any specific tagging numbers
indicated by the factory per a request from the installing
contractor . At this time the voltage, phase and capacity
should be checked against the plans .
3 . Check the unit size against the plans to ensure unit
installation is in the correct location .
4 . After removing the carton, remove the hanger kit from
the fan housing .
5 . Before installation, check the available ceiling height
versus the height of the unit .
6 . Note the location and routing of water piping, conden-
sate drain piping, and electrical wiring . The locations of
these items are clearly marked on submittal drawings .
7 . The installing contractor will find it beneficial to confer
with piping, sheet metal, ceiling and electrical foremen
before installing any conditioners .
NOTE: Check the unit name plate for correct voltage with
the plans before installing the equipment . Also,
make sure all electrical ground connections are
made in accordance with local code .
8 . Remove all shipping blocks in the fan wheel .
9 . Change the airflow direction from straight discharge to
end discharge or vice versa before the unit is installed
in the ceiling . Refer to the section in this bulletin for
instructions .
10 . We recommend that the contractor cover the condi-
tioners with plastic film to protect the machines during
finishing of the building . This is critical while spraying
fireproofing material on bar joists, sandblasting, spray
painting and plastering . If plastic film is not available,
the shipping carton may be modified to cover the units
during construction .
