GENERAL
This work package contains information and operator instructions to be followed for the product flush, short-term
shutdown (less than 96 hours), long-term shutdown with preservation (more than 96 hours), and for an
emergency shutdown of the Lightweight Water Purifier (LWP).
A product flush is performed when system is shutdown for more than 4 hours.
A short term shutdown is performed when more than 4 hours and less than 96 hours and/or LWP is being moved
to another location or exposure to freezing temperatures of 32F or less is expected within 24 hours. This is
basically a product flush followed by draining.
A long-term shutdown is performed when the LWP operation will be suspended for more than 96 hours. The
LWP is thoroughly flushed with dechlorinated product water, preserved and drained.
