Liberty Engineered Products Limited Warranty
Liberty Pumps, Inc. warrants that pumps of its Engineered Product line are free from all factory defects in material and workmanship for a
period of 18 months from the date of installation or 24 months from the date of manufacture, whichever occurs first, and provided that
such products are used in compliance with their intended applications as set forth in the Liberty Engineered Products specifications and
technical manuals. The date of installation shall be determined by a completed pump start-up report and warranty registration form.
A pump startup report, filled out by a qualified installer, is required for warranty to take effect. The report must be submitted within 30
days from the installation date and submitted through the Liberty Pumps website. During the warranty period, the manufacturer's
obligation, and at its discretion, shall be limited to the repair or replacement of any parts found by the manufacturer to be defective,
provided the product is returned freight prepaid to the manufacturer or its 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 or maintained in accordance with
the printed instructions provided; if it has been disassembled, modified, abused or tampered with; if the pump discharge has been
reduced in size; if the pump has been used in water temperatures above those shown in the specifications; if the thermal overload(s) and
seal moisture probe(s) have not been properly connected (where equipped); if the pump has been used in water containing sand, lime,
cement, gravel or other abrasives; if the product has been used to pump chemicals or hydrocarbons; if the product has been moved from
its original installation location, or if the label bearing the serial 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 field labor costs, travel expenses, rental equipment, costs of removal, reinstallation or transportation to
and from the factory or an authorized Liberty Pumps repair facility.
There is no other express warranty. All implied warranties, including those of merchantability and fitness for a particular purpose, are
limited to 18 months from the date of installation or 24 months from the manufacturing date. This Warranty contains the exclusive
remedy of the purchaser, and, where permitted, liability for consequential or incidental damages under any and all warranties are
excluded.
