Pump
Maintenance
NOTE: Any unauthorized field
repair voids the warranty, the
hazardous location rating, and
Factory Mutual approval.
As the motors are oil filled, no
lubrication or other maintenance
is required.
If the heat sensor and seal failure
are hooked up properly, no
attention is necessary as long
as the seal failure indicator
light doesn't come on. To ensure
continuity of the seal sensor
leads, a test light is provided on
intrinsically safe Hydromatic
panels as standard equipment.
Pump should be checked every
quarter for corrosion and wear.
Servicing instructions:
iMPOrTANT: read
directions before replacing any
parts.
WArNiNg: Before handling
these pumps and controls, always
disconnect the power first.
Do not smoke or use sparkable
electrical devices or flames in a
septic (gaseous) or possible
septic sump.
