1.2 Warranty
The company GRIMM Aerosol Technik warrants to each customer that the device described in this doc-
ument has been developed, designed and manufactured according to the existing technical require-
ments for the application described. The device is free of material defects and has passed strict quality
inspections. However, no further warranty is given for an application-specific function or damages due
to material defects or assembly errors. Detailed records are prepared for each unit through production
technology, especially the calibration and validation data.
Should the device fail during the 1-year warranty period or fail to meet the requirements, the company
GRIMM Aerosol Technik has the right to replace defective parts or the device; operating errors are ex-
cepted. The company GRIMM Aerosol Technik shall perform repairs free of charge at the factory. Only
transportation costs and the resulting incidental costs are borne by the customer. On-site repairs are
only carried out in exchange for reimbursement of the travel expenses and service costs. GRIMM as-
sumes no liability for any further claims that would be derived from the warranty.
GRIMM only warrants the goods sold if they are used under normal conditions and according to the
instructions in this manual. The warranty expires at the end of the 12-month period, starting on the day
of delivery from the plant. Returns for warranty work are at the customer’s expense.
The warranty is subject to the following exceptions:
For replacement parts that are replaced or repaired during the warranty period in order to make
the device operational again, the warranty is 90 days under conditions of normal use.
The supplier is not liable for third-party products, batteries or consumables –only the original
warranty is maintained.
Without its written confirmation, GRIMM offers no warranty on parts from suppliers that were
modified and/or removed or installed by untrained personnel.
All of the above replaces any other warranty agreements and/or restrictions. There are no fur-
ther warranty claims, especially outside of normal use.
The buyer is responsible for use and/or operation. Complying with the applicable legal require-
ments and regulations as well as operating the device in accordance with the applicable legal
and operating technology provisions is the responsibility of the buyer. Deviations void the war-
ranty.
Legal means against GRIMM from any party after more than 12 months are groundless.
The buyer and seller agree that this LIMITATION OF LIABILITY which describes the require-
ments and limits shall not be called into question. Both partners are general merchants accord-
ing to German law.
Should a dispute nevertheless arise, the jurisdiction is Traunstein in the Federal Republic of
Germany.
