Seller warrants the products it manufactures to be free from defects in material and workmanship for a period of eigh-
teen (18) months from the date of shipment from Seller’s manufacturing plant or twelve (12) months from date of
installation at the initial end users location, whichever occurs first. In addition, Seller provides the following extended
warranties: (a) three (3) years from the date of shipment on single screw compressor internal rotating parts, (b) two
(2) years from the date of shipment on reciprocating compressors and single screw and reciprocating compressor
parts, and (c) two (2) years on all other parts on a single screw compressor unit. Such warranties do not apply to
ordinary wear and tear. Seller does not warrant that the product complies with any particular law or regulation not ex-
plicitly set forth in the specifications, and Buyer is responsible for ensuring that the product contains all features nec-
essary to safely perform in Buyer’s and its customer’s plants and operations. Buyer must notify Seller of any warranty
claim within ten (10) days after such claim arises, otherwise Buyer waives all rights to such claim. Products supplied
by Seller, which are manufactured by others, are not warranted by Seller, but rather Seller merely passes through the
manufacturer’s warranty to Buyer.
SELLER EXPRESSLY DISCLAIMS ALL OTHER WARRANTIES, WHETHER EXPRESS OR IMPLIED, INCLUDING THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
Unless otherwise agreed in writing, Buyer’s sole remedy for breach of warranty is, at Seller’s option, the re-pair of the
defect, the correction of the service, or the providing a replacement part FOB Seller’s office. Seller will not be respon-
sible for costs of dismantling, lost refrigerant, reassembling, or transporting the product. Further, Seller will not be
liable for any other direct, indirect, consequential, incidental, or special damages arising out of a breach of warranty.
THESE WARRANTY REMEDIES ARE EXCLUSIVE AND ALL OTHER WARRANTY REMEDIES ARE EXCLUDED. Products or
parts for which a warranty claim is made are to be returned transportation prepaid to Seller’s factory. Any improper
use, corrosion, neglect, accident, operation beyond rated capacity, substitution of parts not approved by Seller, or
any alteration or repair by others which, in Seller’s judgement, adversely affects the Product, shall void all warranties
and warranty obligations. Further, Seller shall not be liable under the above warranties should Buyer be in default of its
payment obligations to Seller under this Agreement or any credit agreement.

READ CAREFULLY BEFORE OPERATING YOUR COMPRESSOR.
The following instructions have been prepared to assist in operation of Vilter Vission 20/20 micro-controllers.
The entire manual should be reviewed before attempting to operate.
Vilter micro-controllers are thoroughly inspected at the factory. However, damage can occur in shipment.

reported immediately to the Transportation Company. This way, an authorized agent can examine the unit,
determine the extent of damage and take necessary steps to rectify the claim with no serious or costly delays.
At the same time, the local Vilter representative or the home office should be notified of any claim made.
All inquires should include the Vilter sales order number, compressor serial and model number. These can be
found on the compressor nameplate on the compressor.
