Installation
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.
[ ] Verify that the power supply complies with the electric
heater specifications on the uit nameplate.
[ ] 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!
FOR ACCESS TO COMPONENTS, THE BASE SHEET
METAL SURFACE MUST BE REINFORCED.
Bridging between the unit's main supports may consist
of multiple 2 by 12 boards or sheet metal grating.
Failure to comply could result in death or severe
personal injury from falling.
[ ] 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
material from the receiving location. Take photos of the
damage, if possible. The owner must provide reasonable
evidence that the damage did not occur after delivery.
[ ] Remove the protective plastic coverings that shipped
over the compressors.
Storage
Take precautions to prevent condensate from forming inside
the unit’s electrical compartments and motors if:
a. the unit is stored before it is installed; or,
b. the unit is set on the roof curb, and temporary heat is
provided in the building. Isolate all side panel service
entrances and base pan openings (e.g., conduit
holes, S/A and R/A openings, and flue openings)
from the ambient air until the unit is ready for startup.
Note: Do not use the unit's heater for temporary
heat without first completing the startup procedure
detailed under "Starting the Unit".
Trane will not assume any responsibility for
equipment damage resulting from condensate accumulation
on the unit's electrical and/or mechanical components.
Unit Clearances
Figure 3-1 illustrates the minimum operating and service
clearances for either a single or multiple unit installation.
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, "short-circuiting" of ex-
haust and economizer airflows, or recirculation of hot con-
denser air.
Unit Dimensions & Weight Information
Overall unit dimensional data for a SAHF (20 thru 75 Ton)
cooling only unit is illustrated in Figure 3-2A. Tables 3-1A,
3-1B, and 3-1C list the dimensions. Dimensional data for
SEH_, SFH_, SLH_, SSH_, and SXH_ (20 thru 130 Ton)
units are illustrated in Figure 3-2B. Tables 3-2A, 3-2B, and
3-2C list the dimensions for the 20 thru 75 Ton units. Di-
mensions for 90 through 130 Ton units are listed on the il-
lustration in Figure 3-2C.
A Center-of-Gravity illustration and the dimensional data is
shown in Figure 3-3.
Table 3-3 list the typical unit and curb operating weights.
Weights shown represent approximate operating weights.
Actual weights are stamped on the unit nameplate.
