All  La  Marche  Manufacturing  Co.  equipment  has  been  thoroughly  tested  and  found  to  be  in  proper 

operating  condition  upon  shipment  from  the  factory.    Any  part  or  parts  of  the  equipment  (except 

protective devices, DC connectors and other wear-related items) that prove defective within a one (1) 

year period from the date of our invoice to you shall be replaced without charge providing such defect, in 

our opinion, is due to faulty material or workmanship and not caused by tampering, abuse, misapplication 

or improper installation.  Labor and parts are covered during this one (1) year period.   

For the next four (4) years after the expiration of the one-year warranty, on a parts replacement only 

basis, any part or parts of the equipment (except protective devices, DC connectors and other wear-

related  items)  that  prove  defective  within  the  additional  four  (4)  year  period  shall  be  replaced 

providing  such  defect,  in  our  opinion,  is  due  to  faulty  material  or  workmanship  and  not  caused  by 

tampering,  abuse,  misapplication  or  improper  installation.  During  this  four  (4)  year  period,  the 

warranty covers parts replacement only, no labor or other services are provided by La Marche, nor is La 

Marche obligated to reimburse the owner or any other person for work performed.  

In addition, magnetics and power diodes are warranted for ten (10) years after the date of our invoice to 

you.  The defect in the magnetics or power diodes must, in our opinion, be due to faulty material or 

workmanship and not caused by tampering, abuse misapplication, or improper installation.  Labor and 

replacement magnetics and power diodes are covered during the initial one (1) year period from the date 

of our invoice to you.  During the last nine (9) years of this ten (10) year warranty period for magnetics 

and power diodes, the warranty covers parts replacement only, no labor or other services are provided by 

La Marche, nor is La Marche obligated to reimburse the owner or any other person for work performed. 
Should  a  piece of  equipment  require  major  component  replacement  or  repair  during  warranty  period, 

these can be handled in one of three ways: 

1.

 

If the Purchaser elects to take the responsibility of repairing the equipment and requests replacement part(s), Purchaser or 

Sales Representative must contact Factory for return authorization and a purchase order must be issued. Replacement part(s) 

will be promptly shipped and invoiced. After the defective part(s) are returned and inspected at the Factory, if the defect(s) 

were due to faulty material or workmanship, credit will be issued. 

2.

 

The equipment can be returned to the La Marche factory to have the inspections, parts replacements and testing performed by 

factory  personnel.    Should  it  be  necessary  to  return  a  piece  of  equipment  or  parts  to  the  factory,  the  customer  or  sales 

representative must obtain authorization from the factory.   If upon inspection at the factory, the  defect was due to faulty 

material or workmanship, all repairs will be made at no cost to the customer during the first year. If the Extended Warranty is 

purchased, the parts required for repair will also be at no cost but La Marche will notify the Purchaser of the costs of Labor to 

replace the defective part(s). A Purchase Order to cover this labor is required before repairs will be initiated.  Transportation 

charges or duties shall be borne by Purchaser. 

3.

 

If  the  purchaser  elects  not  to  return  the  equipment  to  the  factory  and  wishes  a  factory  service  representative  to  make 

adjustments and/or repairs at the equipment location, La Marche's field service labor rates will apply.  A purchase order to 

cover the labor and transportation cost is required prior to the deployment of the service representative. 

In accepting delivery of the equipment, the purchaser assumes full responsibility for proper installation, 

installation adjustments and service arrangements.  Should minor adjustments be required, the local La 

Marche sales representative should be contacted to provide this service only. 
All sales are final.  Only standard La Marche units will be considered for return.  A 25% restocking fee is 

charged when return is factory authorized.  Special units are not returnable. 
In  no  event  shall  La  Marche  Manufacturing  Co.  have  any  liability  for  consequential  damages,  or loss, 

damage or expense directly or indirectly arising from the use of the products, or any inability to use them 

either  separately  or  in  combination  with  other  equipment  or  materials,  or  from  any  other  cause.    In 

addition, any alterations of equipment made by anyone other than La Marche Manufacturing Co. renders 

this warranty null and void. 
La Marche Manufacturing Co. reserves the right to make revisions in current production of equipment, 

and assumes no obligation to incorporate these revisions in earlier models. 
The  failure  of  La  Marche  Manufacturing  Co.  to  object  to  provisions  contained  in  customers'  purchase 

orders or other  communications  shall  not  be  deemed  a  waiver  of  the  terms  or  conditions  hereof,  nor 

acceptance of such provisions. 

THE ABOVE WARRANTY IS EXCLUSIVE, SUPERCEDES AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR 

IMPLIED,  INCLUDING  ANY  IMPLIED  WARRANTY  OF  MERCHANTABILITY  OR  FITNESS.    NO  PERSON,  AGENT  OR 

DEALER IS AUTHORIZED TO GIVE ANY WARRANTIES ON BEHALF OF THE MANUFACTURER, OR TO ASSUME FOR THE 

MANUFACTURER ANY OTHER LIABILITY IN CONNECTION WITH ANY OF ITS PRODUCTS UNLESS MADE IN WRITING 

AND SIGNED BY AN OFFICIAL OF THE MANUFACTURER.
