or equivalent, fully insured and shipping charges prepaid.
Correct maintenance, repair, and use are necessary to obtain proper performance from this product. Therefore carefully read the Instruction

(2) Misuse, abuse, neglect or improper installation.
(3) Accidental or intentional damage.
All implied warranties, if any, including warranties of merchantability and fitness for a particular purpose, terminate three (3) years from the
date of the original purchase.
The foregoing constitutes R.L. DRAKE COMPANY’S entire obligation with respect to this product, and the original purchaser shall have no
other remedy and no claim for incidental or consequential damages, losses or expenses. Some states do not allow limitations on how long
an implied warranty lasts or do not allow the exclusions or limitation of incidental or consequential damages, so the above limitation and
exclusion may not apply to you.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state. This warranty shall be
construed under the laws of Ohio.
