Appendix F: Manufacturer’s Extended Parts Warranty

(THIS  IS  YOUR  WARRANTY  IF  YOU  HAVE  PURCHASED  THE  EXTENDED  PARTS  WARRANTY  AS  SHOWN  ON  OUR

INVOICE TO YOU OR IF YOU PURCHASE THE EXTENDED PARTS WARRANTY ANYTIME DURING THE FIRST 12 MONTHS

AFTER THE DATE OF OUR INVOICE)

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, d.c. 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,  d.c.  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. If you return the

equipment to our factory (freight prepaid), we will repair and cover parts and labor.

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 under the extended warranty

during the initial five (5) year period from the date of our invoice to you. During the next five (5) 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 the extended 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 under the Extended Warranty. 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 alteration 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, 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.
