For actual wiring of your unit(s) refer to

The NEC requires that over current protection and supply wire for electric heating equipment be rated at least 125% of the fu
of the circuit. A field supplied disconnect switch should be used to control the input voltage to the unit.

All supply wiring shall conform to the latest edition of the NEC and to all local codes having jurisdiction. Conduit knockouts are
provided in the back of the wiring compartment. Make sure all field wiring connections are properly made and are tight.

LIMITED WARRANTY

Products manufactured by TPI Corporation are warranted to the original consumer to be free from defects in material and
workmanship for twelve (12) months from the original purchase date.

The TPI limited warranty does not cover products that have been modified outside of our factory, damage or failure caused by acts
of God, abuse, misuse, connected to or placed on other than rated voltage, abnormal usage, fault, installation, failure to follow
suggested maintenance procedures enclosed with the product, improper maintenance or any repairs other than those provided by
an authorized TPI service center.

There are no obligations or liabilities on the part of the Corporation for consequential damages arising out of or in
connection with the use or performance of the product or other indirect damages with respect to loss of property,
revenues, profit, costs of removal installation, or reinstallation.
