Kenco Engineering KSF Sight Flow Indicator - Manual (Page 2)

FLOW INDICATOR POSITIONING
• The plain model can be mounted in any plane or position
• The propeller model can be mounted in any plane or position (except horizontally
facing out and the nameplate upside down)
• The drip tube model should be mounted vertically with the flow downward
• The flapper model should be mounted horizontally or mounted vertically with the
flow upward
START-UP
*** CAUTION: Prior to start up compare the data on the information tag to the
conditions of the system. If any discrepancy is apparent, contact KENCO for
clarification and advice.
Gaskets and seals frequently assume a compression-set (loss of resiliency) over a
period of time. Some materials tend to compression-relieve or creep. It is
recommended that the unit have its glass retainer fasteners retorqued to the proper
value before start-up.
*** CAUTION: Do not tighten any fasteners while the equipment is in operation.
Check the glass in the unit prior to start-up to ensure that there are no chips, scratches,
or blemishes. Use a flashlight or another source of bright concentrated light to
examine the glass carefully. If any type of flaw is apparent, start-up should be delayed
pending the replacement of the glass and gaskets.
MAINTENANCE
Periodic visual inspections should be made to ensure that no leaks are evident and
that there is no clouding, scratching, or blemishing of the glass. In new installations,
daily inspections are recommended to establish a routine inspection cycle.
Keep glasses clean, using commercial glass cleaners. Cleaning must be done without
removing the glass. Never use harsh abrasives, wire brushes, steel wool, metal
scrapers or other materials could scratch the glass.
*** CAUTION: Do not attempt to clean when the equipment is in operation.
A. GLASS INSPECTION
To examine for scratches, shine a bright concentrated light at about a 45 degree angle
to the glass. Anything that glistens brightly must be looked at closely. Any scratch
that glistens and catches a fingernail is cause for glass replacement. If the inner
surface appears cloudy or roughened and will not respond to cleaning procedures, the
glass must be replaced, since this is evidence of a chemical attack.
