2. Remo v e all packaging or b lockers.
3. Remo v e all of the accessories or packages that
w ere shipped on the same skid, inside the air
handler or inside the control enclos u re.
4. Inspect the air handler to:
• Verify that there is no damage as a res u lt of

• Ens u re that it is appropriately rated for the
u tilities a v aila b le at the installation site.
• Verify that the lifting l u gs are intact,
u ndamaged and sec u red to the air handler.
• Ens u re factory-installed hard w are is

Shipped Vertically
Models TT112 thro u gh TT218 are shipped v ertically
