7 . MAINTENANCE AND GUARANTEE
The P11P, P13P and P13B transducers do not
require any periodical maintenance. In case of
some incorrect unit operations:
1. In the 18 months period from the date of
shipment:
One should return the transducer to the
LUMELs Quality Control Dept. If the unit has
been used in compliance with the instructions,
LUMEL S.A. guarantees to repair it free of
charge. The disassembling of the housing
causes the cancellation of the granted
guarantee.
2. After the guarantee period:
One should turn over the transducer to repair
it in a certified service workshop. Spare parts
are available for the period of ten years from
the date of purchase.
LUMEL S.A. reserves the right to make
changes in design and specifications of any
products as engineering advances or
necessity requires.
