INTERMITTENT DUTY ONLY!
Pump switch must be near pump and tank so operator
can hear pump running.
Make sure shut-off valve to pump and dump valve [if
equipped] are both open. Turn on momentary switch
and pump out tank.
When tank is empty, pump will get louder with a high
pitch sound. Immediately turn pump off, or damage to
impeller and housing will occur.
Do not run pump dry for more than 15 – 20 seconds.
Flush tank and pump with water after each use. This
macerator will handle normal waste, tissues, cigarettes,
fish scales, etc. It is not designed to handle large hard
objects such as large bones or fruit pits.
Periodic Maintenance and Storage: Flush with water after
each use. Check wire connections occasionally. After
periods of non-use, impeller can stick. To loosen, open rear
shaft cover and turn motor shaft clockwise with a flat tip
screwdriver. Then replace shaft cover. For extended periods
of non-use, pump impeller can be lubricated by running a
small amount of mineral oil through holding tank system.
Maintenance: Turn off all power!
