4.6 CLEAN-UP
To help remove potentially dangerous chemicals prior to service or shipment, the
pump should be flushed with DI water or disassembled and thoroughly cleaned.
Allow DI water to flush through the inlet and out the outlet to prevent pressure
build up.
CAUTION:
When handling pump, wear appropriate personal protection
gear, including safety glasses.

maintenance procedures to ensure its continued high performance. This section
and the next (4.8
