These operating instructions are an integral part of both the device and our terms of

warranty. They must be handed over to the user. The technical design of the appliance

is subject to change without prior notification. PEHA products are manufactured
and quality-checked with the latest technology according to applicable national and
international regulations. Nevertheless, if a product should exhibit a defect, PEHA
warrants to make remedy as follows (regardless of any claims against the dealer to
which the end user may be entitled as a result of the sales transaction):
In the event of a justified and properly established claim, PEHA shall exercise its
prerogative to either repair or replace the defective device. Further claims or liability
for consequential damage are explicitly excluded. A justifiable deficiency is deemed to
exist if the device exhibits a structural, manufacturing, or material defect that makes it
unusable or substantially impairs its utility at the time it is turned over to the end user.
The warranty does not apply to natural wear, improper usage, incorrect connection,
device tampering or the effects of external influences. The warranty period is 24 months
from the date of purchase by the end user from a dealer and ends not later than 36
months after the device's date of manufacture. German law shall be applicable for the

settlement of warranty claims.
