authorized service center, and provided that none of the following warranty-voiding characteristics are evident.
The manufacturer shall not be liable under this Warranty if the product has not been properly installed; if it has been
disassembled, modified, abused or tampered with; if the electrical cord has been cut, damaged or spliced; if the pump
discharge has been reduced in size; if the pump has been used in water temperatures above the advertised rating, or
water containing sand, lime, cement, gravel or other abrasives; if the product has been used to pump chemicals or
hydrocarbons; if a non-submersible motor has been subjected to excessive moisture; or if the label bearing the serial,
model and code number has been removed. Liberty Pumps, Inc. shall not be liable for any loss, damage or expenses
resulting from installation or use of its products, or for consequential damages, including costs of removal, reinstallation or
transportation.
