Macerator Pump (optional)
The macerator pump is designed to empty RV holding tanks of normal waste. The
unique dual-cut blade design ensures waste is ground up thoroughly. A flow rate of
up to (13) gallons per minute conveniently empties any tank in minutes. A standard
1” garden hose can be used to pump waste a reasonable distance if you are not able
to park next to a dump station.
Operation
The pump switch is located near the pump so that the operator can hear the pump
running. Make sure shut-off valve to pump and dump valve (if equipped) are both
open. Turn on the switch to self-priming pump and pump out the tank. When the
tank is empty, the pump will get louder with a high-pitch sound. Immediately turn
the pump off, or damage to the housing would occur. Do not run the pump dry for
more than fifteen to twenty seconds. Flush the tank and pump with water after each
use. The macerator will handle normal waste tissue.
CAUTION
The macerator will not handle large or hard objects such as bone, fruit pits,
rags, or feminine sanitary products.
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, the pump impeller can be lubricated by running a
small amount of mineral oil through the holding tank system. Whenever possible,
drain the holding tanks prior to traveling. The carrying capacity of your unit will be
reduced if water is left in the black or gray tanks. The holding tanks should only be
drained when they are at least 3/4 full. Doing this will provide enough water to
allow the complete flushing of waste materials in the drain lines and hose. If the
tanks are not 3/4 full, add enough water to allow for enough flushing.
After you have drained the black water tank, immediately drain the gray water
tank. Doing this helps to flush the black water from the sewage hose.
