PerkinElmer Photovac 2020 User manual

Warning: Limitation of Liability
The ultimate responsibility of the consequences of use of toxic
compounds rests with the user. PerkinElmer’s role is as a supplier of
instrumentation to assist in the early detection of hazardous
conditions involving such compounds.
2020 represents a major advance in this field and, as with all
complex instruments, it is vitally important to ensure that 2020 is
maintained in accordance with PerkinElmer’s instructions and that
proper calibration is regularly performed.
As with any complex device, 2020 is subject to failure and, while
PerkinElmer has taken, and continues to take, all possible
precautions to (a) reduce the possibility of failure, and (b) warn the
user in the event of failure, circumstances may occasionally occur in
which there is a failure despite such precautions on PerkinElmer’s
part. PerkinElmer regrets that it cannot accept liability for damages
of any kind caused as a result of either failure of the user to follow
instructions or of 2020 to perform.
