ATTENTION: An incorrectly applied or installed heat exchanger
can result in component damage or a reduction in product life.
Wiring or application errors, such as, undersizing the heat
exchanger, incorrect or inadequate AC supply, or excessive
ambient temperatures may result in malfunction of the system.
!
ATTENTION: Only qualified personnel familiar with adjustable
frequency AC drives and associated machinery should plan or
implement the installation, start-up, and subsequent maintenance
of the system. Failure to comply may result in personal injury and/
or equipment damage.
