All  La Marche Manufacturing  Co. equipment has been thoroughly tested  and  found  to be in proper  operating 
condition  upon  shipment  from  the  factory  and  is  warranted  to  be  free  from  any  defect  in  workmanship  and 
material  that  may  develop  within  one  year  from  date  of  purchase.  In  addition  to  the  standard  one  (1)  year 

warranty, La Marche warrants its magnetics and power diodes on a parts replacement basis only for nine (9) 
more years under normal use. 
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 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.  Magnetics and power diodes are warranted for ten (10) years after date of purchase.  During the 
last nine (9) years of this ten (10) year warranty 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.  
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  inverters will be considered for return.  A 25% restocking fee is 
charged when return is factory authorized.  Special inverters 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. Failure 

to follow safety precautions specified  by the manufacturer  during  replacement of components or  verifications 
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, SUPERSEDES 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.
