PRIMING. Be sure suction lines are airtight or pump will not
self prime.
DISCHARGE. When transferring liquids further than 25 feet,
use one size larger discharge line than discharge port size.
RUNNING DRY. Unit depends on liquid pumped for
lubrication. DO NOT RUN DRY for more than 30 seconds. Lack
of liquid will damage the impeller.
TEMPERATURES. The operating temperature limits of the
pump depend on the impeller compound. The following
ranges apply:
EPDM - 45° to 185° F (7° to 85° C).
CLEANING. Before using pump, it should be disassembled
and cleaned to remove any dust and dirt resulting from
storage or shipping. Wash parts in standard cleaning solutions
approved for handling stainless steel. Thoroughly rinse before
reassembly.
DO NOT USE IODINE BASED SANITIZERS as the iodine attacks
the elastomer materials used in the impeller.
All parts have been expertly machined and polished.
HANDLE WITH CARE. DO NOT DROP OR MISHANDLE.
