WARRANTY POLICY
The seller is obligated to provide a warranty of five years for the de-
livered goods regarding material and manufacturing. The warranty
period is considered to start on the delivery date of the product. If
a defect in raw materials or a production flaw is found, the seller is
obligated, when the product is sent to the seller without delay or
before expiration of the warranty, to amend the mistake at his/her
discretion either by repairing the defective product or by delivering
free of charge to the buyer a new flawless product and sending it to
the buyer. Delivery costs for the repair under warranty will be paid
by the buyer and the return costs by the seller. The warranty does
not comprise damages caused by accident, lightning, flood or other
natural phenomenon, normal wear and tear, improper or careless
handling, abnormal use, overloading, improper storage, incorrect
care or reconstruction, or changes and installation work not done
by the seller or his/her authorized representative. The selection of
materials for devices prone to corrosion is the buyer’s responsibility,
unless otherwise is legally agreed upon. Should the manufacturer
alter the structure of the device, the seller is not obligated to make
comparable changes to devices already purchased. Appealing for
warranty requires that the buyer has correctly fulfilled his/her duties
arisen from the delivery and stated in the contract. The seller will give
a new warranty for goods that have been replaced or repaired within
the warranty, however only to the expiration of the original product’s
warranty time. The warranty includes the repair of a defective part or
device, or if needed, a new part or device, but not installation or ex-
change costs. Under no circumstance is the seller liable for damages
compensation for indirect damage.
