Unit Inspection
As soon as the unit arrives at the job site
[ ] Verify that the nameplate data matches the data on the
sales order and bill of lading (including electrical data).
[ ] Verify that the power supply complies with the unit name-
plate specifications.
[ ] Visually inspect the exterior of the unit, including the roof,
for signs of shipping damage.
[ ] Check for material shortages. Refer to the Component
Layout and Shipwith Location illustration.
If the job site inspection of the unit reveals damage or mate-
rial shortages, file a claim with the carrier immediately.
Specify the type and extent of the damage on the "bill of
lading" before signing.
[ ] Visually inspect the internal components for shipping
damage as soon as possible after delivery and before it
is stored. Do not walk on the sheet metal base pans.
WARNING
No Step Surface!
Do not walk on the sheet metal drain pan. Walking on
the drain pan could cause the supporting metal to col-
lapse. Failure of the drain pan could result in death or
serious injury.
Bridging between the unit's main supports may consist
of multiple 2 by 12 boards or sheet metal grating.
[ ] If concealed damage is discovered, notify the carrier's
terminal of damage immediately by phone and by mail.
Concealed damage must be reported within 15 days.
Request an immediate joint inspection of the damage by
the carrier and the consignee. Do not remove damaged ma-
terial from the receiving location. Take photos of the dam-
age, if possible. The owner must provide reasonable evi-
dence that the damage did not occur after delivery.
[ ] Notify the appropriate Trane office before installing or re-
pairing a damaged unit.
Installation
Unit Clearances
Figure 1 illustrates the minimum operating and service
clearances for either a single, multiple, or pit application.
These clearances are the minimum distances necessary to
assure adequate serviceability, cataloged unit capacity, and
peak operating efficiency.
Providing less than the recommended clearances may re-
sult in condenser coil starvation or recirculation of hot con-
denser air.
Locate the unit as close to the applicable system support
equipment as possible to minimize refrigerant piping
lengths.
Unit Dimensions & Weight Information
Overall unit dimensional data for each unit is illustrated in
Figure 2.
A Center-of-Gravity illustration and the dimensional data is
shown in Figure 3.
Table 1 lists the typical unit operating and point loading
weights.
Foundation
If the unit is installed at ground level, elevate it above the
snow line. Provide concrete footings at each support loca-
tion or a slab foundation for support. Refer to Table 1 for the
unit operating and point loading weights when constructing
the footing foundation.
Anchor the unit to the footings or slab using hold down bolts
or isolators. Isolators should be installed to minimize the
transmission of vibrations into the building. Refer to the
"Unit Isolation" section for spring or rubber isolator installa-
tion instructions.
For rooftop applications, ensure the roof is strong enough to
support the unit. Refer to Table 1 for the unit operating
weights.
Anchor the unit to the roof with hold-down bolts or isolators.
Follow the instructions under "Unit Isolation" for proper iso-
lator placement and installation.
Check with a roofing contractor for proper waterproofing
procedures.
